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.

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 ★★

Trending Cyber News and Threat Intelligence First-Ever Attack Leveraging Kubernetes RBAC to Backdoor Clusters (published: April 21, 2023) A new Monero cryptocurrency-mining campaign is the first recorded case of gaining persistence via Kubernetes (K8s) Role-Based Access Control (RBAC), according to Aquasec researchers. The recorded honeypot attack started with exploiting a misconfigured API server. The attackers preceded by gathering information about the cluster, checking if their cluster was already deployed, and deleting some existing deployments. They used RBAC to gain persistence by creating a new ClusterRole and a new ClusterRole binding. The attackers then created a DaemonSet to use a single API request to target all nodes for deployment. The deployed malicious image from the public registry Docker Hub was named to impersonate a legitimate account and a popular legitimate image. It has been pulled 14,399 times and 60 exposed K8s clusters have been found with signs of exploitation by this campaign. Analyst Comment: Your company should have protocols in place to ensure that all cluster management and cloud storage systems are properly configured and patched. K8s buckets are too often misconfigured and threat actors realize there is potential for malicious activity. A defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) approach is a good mitigation step to help prevent actors from highly-active threat groups.

CyberheistNews Vol 13 #14 CyberheistNews Vol 13 #14  |   April 4th, 2023 [Eyes on the Prize] How Crafty Cons Attempted a 36 Million Vendor Email Heist The details in this thwarted VEC attack demonstrate how the use of just a few key details can both establish credibility and indicate the entire thing is a scam. It\'s not every day you hear about a purely social engineering-based scam taking place that is looking to run away with tens of millions of dollars. But, according to security researchers at Abnormal Security, cybercriminals are becoming brazen and are taking their shots at very large prizes. This attack begins with a case of VEC – where a domain is impersonated. In the case of this attack, the impersonated vendor\'s domain (which had a .com top level domain) was replaced with a matching .cam domain (.cam domains are supposedly used for photography enthusiasts, but there\'s the now-obvious problem with it looking very much like .com to the cursory glance). The email attaches a legitimate-looking payoff letter complete with loan details. According to Abnormal Security, nearly every aspect of the request looked legitimate. The telltale signs primarily revolved around the use of the lookalike domain, but there were other grammatical mistakes (that can easily be addressed by using an online grammar service or ChatGPT). This attack was identified well before it caused any damage, but the social engineering tactics leveraged were nearly enough to make this attack successful. Security solutions will help stop most attacks, but for those that make it past scanners, your users need to play a role in spotting and stopping BEC, VEC and phishing attacks themselves – something taught through security awareness training combined with frequent simulated phishing and other social engineering tests.

Trending Cyber News and Threat Intelligence Threat Analysis: Active C2 Discovery Using Protocol Emulation Part3 (ShadowPad) (published: October 27, 2022) ShadowPad is a custom, modular malware in use by multiple China-sponsored groups since 2015. VMware researchers analyzed the command-and-control (C2) protocol in recent ShadowPad samples. They uncovered decoding routines and protocol/port combinations such as HTTP/80, HTTP/443, TCP/443, UDP/53, and UDP/443. Active probing revealed 83 likely ShadowPad C2 servers (during September 2021 to September 2022). Additional samples communicating with this infrastructure included Spyder (used by APT41) and ReverseWindow (used by the LuoYu group). Analyst Comment: Researchers can use reverse engineering and active probing to map malicious C2 infrastructure. At the same time, the ShadowPad malware changes the immediate values used in the packet encoding per variant, so finding new samples is crucial for this monitoring.

Raspberry Robin works as a three-file infection: Raspberry Robin LNK file on an USB drive, Raspberry Robin DLL (aka Roshtyak) backdoor, and a heavily-obfuscated .NET DLL that writes LNKs to USB drives. Microsoft researchers analyzed several infection chains likely centered around threat group EvilCorp (aka DEV-0206/DEV-0243). Besides being the initial infection vector, Raspberry Robin was seen delivered by the Fauppod malware, which shares certain code similarities both with Raspberry Robin and with EvilCorp’s Dridex malware. Fauppod/Raspberry Robin infections were followed by additional malware (Bumblebee, Cobalt Strike, IcedID, TrueBot), and eventually led to a ransomware infection (LockBit, Clop). Analyst Comment: Organizations are advised against enabling Autorun of removable media on Windows by default, as it allows automated activation of an inserted, Raspberry Robin-infected USB drive.

Trending Cyber News and Threat Intelligence Hacker Pwns Uber Via Compromised VPN Account (published: September 16, 2022) On September 15, 2022, ride-sharing giant Uber started an incident response after discovering a data breach. According to Group-IB researchers, download file name artifacts point to the attacker getting access to fresh keylogger logs affecting two Uber employees from Indonesia and Brazil that have been infected with Racoon and Vidar stealers. The attacker allegedly used a compromised VPN account credentials and performed multifactor authentication fatigue attack by requesting the MFA push notification many times and then making a social-engineering call to the affected employee. Once inside, the attacker allegedly found valid credentials for privilege escalation: a PowerShell script containing hardcoded credentials for a Thycotic privileged access management admin account. On September 18, 2022, Rockstar Games’ Grand Theft Auto 6 suffered a confirmed data leak, likely caused by the same attacker. Analyst Comment: Network defenders can consider setting up alerts for signs of an MFA fatigue attack such as a large number of MFA requests in a relatively short period of time.

Trending Cyber News and Threat Intelligence What’s With The Shared VBA Code Between Transparent Tribe And Other Threat Actors? (published: February 9, 2022) A recent discovery has been made that links malicious VBA macro code between multiple groups, namely: Transparent Tribe, Donot Team, SideCopy, Operation Hangover, and SideWinder. These groups operate (or operated) out of South Asia and use a variety of techniques with phishing emails and maldocs to target government and military entities within India and Pakistan. The code is similar enough that it suggests cooperation between APT groups, despite having completely different goals/targets. Analyst Comment: This research shows that APT groups are sharing TTPs to assist each other, regardless of motive or target. Files that request content be enabled to properly view the document are often signs of a phishing attack. If such a file is sent to you via a known and trusted sender, that individual should be contacted to verify the authenticity of the attachment prior to opening. Thus, any such file attachment sent by unknown senders should be viewed with the utmost scrutiny, and the attachments should be avoided and properly reported to appropriate personnel.

While they were adopted for certain niche uses, they never did quite reach their full potential. They are a bit like Rick Astley in that regard, really popular for one song, but well after the boat had sailed. Do not get me wrong, Rick Astley achieved a lot. In recent years, he has become immortalized as a meme and Rick roller, but he could have been so much more. However, in recent years, with lockdown and the drive to keep things at arms length, QR codes have become an efficient way to facilitate contactless communications, or the transfer of offers without physically handing over a coupon. As this has grown in popularity, more people have become familiar with how to generate their own QR codes and how to use them as virtual business cards, discount codes, links to videos and all sorts of other things. QRime Codes As with most things, once they begin to gain a bit of popularity, criminals move in to see how they can manipulate the situation to their advantage. Recently, we have seen fake QR codes stuck to parking meters enticing unwitting drivers to scan the code, and hand over their payment details believing they were paying for parking, whereas they were actually handing over their payment information to criminals. The rise in QR code fraud resulted in the FBI releasing an advisory warning against fake QR codes that are being used to scam users. In many cases, a fake QR code will lead people to a website that looks like the intended legitimate site. So, the usual verification process of checking the URL and any other red flags apply.

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. Administrators should keep their important public-facing applications (such as Microsoft Exchange and Oracle GlassFish Server) updated.

Historically, Phorpiex utilized sextortion, ransomware delivery, and cryptocurrency clipping. Twizt however, appears to be primarily focused on stealing cryptocurrency and have stolen half a million dollars since November 2020 in the form of Bitcoin, Ether and ERC20 tokens.The botnet features departure from it’s traditional command and control (C2) infrastructure, opting for peer-to-peer (P2P) communications between infected hosts, eliminating the need for C2 communication as each host can fulfill that role. Analyst Comment: Bots within a P2P network need to communicate regularly with other bots to receive and share commands. If the infected bots are on a private network, private IP addresses will be used. Therefore, careful monitoring of network traffic will reveal suspicious activity, and a spike in network resource usage as opposed to the detection of C2 IP addresses.

These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. 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.

Trending Cyber News and Threat Intelligence UK and Allies Accuse China for a Pervasive Pattern of Hacking, Breaching Microsoft Exchange Servers (published: July 19, 2021) On July 19th, 2021, the US, the UK, and other global allies jointly accused China in a pattern of aggressive malicious cyber activity. First, they confirmed that Chinese state-backed actors (previously identified under the group name Hafnium) were responsible for gaining access to computer networks around the world via Microsoft Exchange servers. The attacks took place in early 2021, affecting over a quarter of a million servers worldwide. Additionally, APT31 (Judgement Panda) and APT40 (Kryptonite Panda) were attributed to Chinese Ministry of State Security (MSS), The US Department of Justice (DoJ) has indicted four APT40 members, and the Cybersecurity and Infrastructure Security Agency (CISA) shared indicators of compromise of the historic APT40 activity. Analyst Comment: Network defense-in-depth and adherence to information security best practices can assist organizations in reducing the risk. Pay special attention to the patch and vulnerability management, protecting credentials, and continuing network hygiene and monitoring. When possible, enforce the principle of least privilege, use segmentation and strict access control measures for critical data.

Trending Cyber News and Threat Intelligence Google: This Spectre proof-of-concept shows how dangerous these attacks can be (published: March 15, 2021) Google has released a proof of concept (PoC) code to demonstrate the practicality of Spectre side-channel attacks against a browser's JavaScript engine to leak information from its memory. Spectre targeted the process in modern CPUs called speculative execution to leak secrets such as passwords from one site to another. While the PoC demonstrates the JavaScript Spectre attack against Chrome 88's V8 JavaScript engine on an Intel Core i7-6500U CPU on Linux, Google notes it can easily be tweaked for other CPUs, browser versions and operating systems. Analyst Comment: As the density of microchip manufacturing continues to increase, side-channel attacks are likely to be found across many architectures and are difficult (and in some cases impossible) to remediate in software. The PoC of the practicality of performing such an attack using javascript emphasises that developers of both software and hardware be aware of these types of attacks and the means by which they can be used to invalidate existing security controls. Tags: CVE-2017-5753 Threat Assessment: DearCry Ransomware (published: March 12, 2021) A new ransomware strain is being used by actors to attack unpatched Microsoft Exchange servers. Microsoft released patches for four vulnerabilities that are being exploited in the wild. The initial round of attacks included installation of web shells onto affected servers that could be used to infect additional computers. While the initial attack appears to have been done by sophisticated actors, the ease and publicity around these vulnerabilities has led to a diverse group of actors all attempting to compromise these servers. Analyst Comment: Patch and asset management are a critical and often under-resourced aspect of defense in depth.

Trending Cyber News and Threat Intelligence US 2020 Presidential Apps Riddled with Tracking and Security Flaws (published: September 17, 2020) The Vote Joe 2020 application has been found to be potentially leaking personal data about voters. The app is used by the Joe Biden campaign to engage with voters and get supporters to send out promotional text messages. Using TargetSmart, an intelligence service, the app receives their predictions via API endpoint which has been found to be returning additional data. Voter preference and voter prediction could be seen, while voter preference is publically accessible, the information for TargetSmart was not meant to be publicly available. The app also let users from outside of the United States download, allowing for non-US citizens to have access to the data, as there was no email verification. Vote Joe isn’t the only campaign app with security issues, as the Donald Trump application exposed hardcoded secret keys in the APK. Recommendation: The exposure of Personally Identifiable Information (PII) requires affected individuals to take precautionary measures to protect their identity and their finances. Identity theft services can assist in preventing illicit purchases, or applying for financial services from taking place by actors using stolen data.

In an apparent ransomware attack, the hospital’s systems crashed with staff unable to access data. While there was no apparent ransom note, 30 servers at the hospital had been encrypted last week, with a ransom note left on one server addressed to Heinrich Heine University. Duesseldorf police contacted the perpetrators to inform them they had attacked the hospital instead of the university, with the perpetrators providing decryption keys, however patients had to be rerouted to other hospitals and therefore a long time before being treated by doctors. Recommendation: Educate your employees on the risks of opening attachments from unknown senders. Anti-spam and antivirus applications provided by trusted vendors should also be employed. Emails that are received from unknown senders should be carefully avoided, and attachments from such senders should not be opened. Furthermore, it is important to have a comprehensive and tested backup solution in place, in addition to a business continuity plan for the unfortunate case of ransomware infection.
