2025-02-11 20:00:00 | Cybercrime: A Multifaceted National Security Threat (lien direct) | Executive Summary Cybercrime makes up a majority of the malicious activity online and occupies the majority of defenders\' resources. In 2024, Mandiant Consulting responded to almost four times more intrusions conducted by financially motivated actors than state-backed intrusions. Despite this overwhelming volume, cybercrime receives much less attention from national security practitioners than the threat from state-backed groups. While the threat from state-backed hacking is rightly understood to be severe, it should not be evaluated in isolation from financially motivated intrusions. A hospital disrupted by a state-backed group using a wiper and a hospital disrupted by a financially motivated group using ransomware have the same impact on patient care. Likewise, sensitive data stolen from an organization and posted on a data leak site can be exploited by an adversary in the same way data exfiltrated in an espionage operation can be. These examples are particularly salient today, as criminals increasingly target and leak data from hospitals. Healthcare\'s share of posts on data leak sites has doubled over the past three years, even as the number of data leak sites tracked by Google Threat Intelligence Group has increased by nearly 50% year over year. The impact of these attacks mean that they must be taken seriously as a national security threat, no matter the motivation of the actors behind it. Cybercrime also facilitates state-backed hacking by allowing states to purchase cyber capabilities, or co-opt criminals to conduct state-directed operations to steal data or engage in disruption. Russia has drawn on criminal capabilities to fuel the cyber support to their war in Ukraine. GRU-linked APT44 (aka Sandworm), a unit of Russian military intelligence, has employed malware available from cybercrime communities to conduct espionage and disruptive operations in Ukraine and CIGAR (aka RomCom), a group that historically focused on cybercrime, has conducted espionage operations against the Ukrainian government since 2022. However, this is not limited to Russia. Iranian threat groups deploy ransomware to raise funds while simultaneously conducting espionage, and Chinese espionage groups often supplement their income with cybercrime. Most notably, North Korea uses state-backed groups to directly generate revenue for the regime. North Korea has heavily targeted cryptocurrencies, compromising exchanges and individual victims\' crypto wallets. Despite the overlaps in effects and collaboration with states, tackling the root causes of cybercrime requires fundamentally different solutions. Cybercrime involves collaboration between disparate groups often across borders and without respect to sovereignty. Any solution requires international cooperation by both law enforcement and intelligence agencies to track, arrest, and prosecute these criminals. Individual takedowns can have important temporary effects, but the collaborative nature of cybercrime means that the disrupted group will be quickly replaced by others offering the same service. Achieving broader success will require collaboration between countries and public and private sectors on systemic solutions such as increasing education and resilience efforts. aside_block | Ransomware Malware Tool Vulnerability Threat Legislation Medical Cloud Technical | APT 41 APT 38 APT 29 APT 43 APT 44 | ★★★ |

2024-10-25 16:11:10 | The Crypto Game of Lazarus APT: Investors vs. Zero-days (lien direct) | ## Snapshot Researchers at Kaspersky identified a cyberattack campaign by the Lazarus APT (tracked by Microsoft as [Diamond Sleet](https://security.microsoft.com/intel-profiles/b982c8daf198d93a2ff52b92b65c6284243aa6af91dda5edd1fe8ec5365918c5)) group and its BlueNoroff subgroup (tracked by Microsoft as [Sapphire Sleet](https://security.microsoft.com/intel-profiles/45e4b0c21eecf6012661ef6df36a058a0ada1c6be74d8d2011ea3699334b06d1)), which exploited a zero-day vulnerability in Google Chrome to execute remote code through a fake decentralized finance (DeFi) game targeting individuals in the cryptocurrency space. ## Description The attackers used a type confusion in V8 vulnerability in Google Chrome\'s Maglev optimizing compiler, [CVE-2024-4947](https://security.microsoft.com/intel-explorer/cves/CVE-2024-4947/), to gain read/write access to the entire address space of the Chrome process. They bypassed the V8 sandbox by exploiting a vulnerability in the Irregexp VM, allowing attackers to access memory outside the bounds of the register arrays, and to manipulate pointers and execute shellcode. The campaign involved social engineering tactics, including a malicious website that offered to download a beta version of the computer game called "DeTankZone" as a lure, which was a modified version of a legitimate game called DeFiTankLand. The initial infiltration was done through a hidden script on the website that exploited the Chrome vulnerabilities, allowing attackers to gain full control of the victim\'s device. The attackers built a presence on social media platforms and attempted to contact cryptocurrency influencers to promote their malicious website. Kaspersky reported the zero-day vulnerability to Google, which [released an update](https://chromereleases.googleblog.com/2024/05/stable-channel-update-for-desktop_15.html) to fix the issue in May 2024 on Chrome version 125.0.6422.60/.61. ## Microsoft Analysis and Additional OSINT Context [Microsoft](https://www.microsoft.com/en-us/security/blog/2024/05/28/moonstone-sleet-emerges-as-new-north-korean-threat-actor-with-new-bag-of-tricks/) attributes this activity to [Moonstone Sleet](https://security.microsoft.com/intel-profiles/8ba84cecf73bd9aca4e4ff90230dc1f277c039f78c40c1938b6f74b1b7cce20f), a threat actor behind a cluster of malicious activity that Microsoft assesses is North Korean state-aligned. Since February 2024, Microsoft has observed Moonstone Sleet infecting devices using the malicious tank game DeTankWar, also called DeFiTankWar, DeTankZone, or TankWarsZone. The game is portrayed as a nonfungible token (NFT)-enabled play-to-earn game, available on Windows, Mac, and Linux. In this campaign, Moonstone Sleet typically approaches its targets through messaging platforms, such as LinkedIn and Telegram, or by email with a link to download the game. When targeted users launch the game, the ZIP file is downloaded, and multiple malicious DLLs are loaded. This leads to connections to command-and-control (C2) infrastructure using a custom malware loader Microsoft calls YouieLoad. YouieLoad loads malicious payloads in memory and creates malicious services that perform functions such as network and user discovery and browser data collection. For compromised devices of particular interest to the group, the threat actor launches hands-on-keyboard commands with further discovery and conducts credential theft. The threat actors presented themselves as game developers seeking investment or developer support and either masquerading as a legitimate blockchain company or using fake companies like one called C.C. Waterfall, a purported IT consulting organization. Moonstone Sleet created a robust public campaign that includes the websites detankwar\[.\]com and defitankzone\[.\]com, and many X (Twitter) accounts for the personas it uses to approach targets and for the game itself. In a similar campaign, Moonstone Sleet sent emails, also using its fake company C.C. Waterfall, where they emailed higher education organizations, again, claiming the company was | Ransomware Malware Tool Vulnerability Threat | APT 38 | ★★ |

## Snapshot Last week\'s OSINT reporting highlights a broad spectrum of cyber threats with notable trends in malware campaigns, espionage, and ransomware attacks. Phishing remains a dominant attack vector, delivering a variety of payloads like custom backdoors, infostealers, and ransomware. Nation-state actors such as Russia\'s APT29 (Midnight Blizzard) and China\'s Earth Lusca were prominent, focusing on espionage and targeting specific regions like East Asia and the Middle East. Other notable threats included the use of deepfakes for scam campaigns and the exploitation of unpatched vulnerabilities in widely used software like Microsoft Office and WPS Office. The targeting of organizations ranged from government entities to private sector businesses, with some attacks focusing on specific industries like finance, healthcare, and technology. ## Description 1. [Unique Malware Campaign \'Voldemort\'](https://sip.security.microsoft.com/intel-explorer/articles/3cc65ab7): Proofpoint researchers uncovered a phishing campaign distributing custom malware via emails impersonating tax authorities across multiple countries. The malware, likely motivated by espionage, uses advanced techniques like abusing Google Sheets for command-and-control (C2) to avoid detection. 2. [Python-Based Infostealer \'Emansrepo\'](https://sip.security.microsoft.com/intel-explorer/articles/94d41800): FortiGuard Labs identified Emansrepo, a Python-based infostealer targeting browser data and files via phishing emails. The malware has evolved into a sophisticated multi-stage tool, expanding its capabilities to steal sensitive data like cryptocurrency wallets. 3. [Deepfake Scams Using Public Figures](https://sip.security.microsoft.com/intel-explorer/articles/6c6367c7): Palo Alto Networks researchers discovered deepfake scams impersonating public figures to promote fake investment schemes. These scams, involving a single threat actor group, target global audiences with AI-generated videos hosted on domains with significant traffic. 4.

Written by: Robert Wallace, Blas Kojusner, Joseph Dobson
Where money goes, crime follows. The rapid growth of Web3 has presented new opportunities for threat actors, especially in decentralized finance (DeFi), where the heists are larger and more numerous than anything seen in the traditional finance sector. Mandiant has a long history of investigating bank heists. In 2016, Mandiant investigated the world\'s largest bank heist that occurred at the Bank of Bangladesh and resulted in the theft of $81 million by North Korea\'s APT38. While the group\'s operations were quite innovative and made for an entertaining 10-episode podcast by the BBC, it pales in comparison to Web3 heists. In 2022, the largest DeFi heist occurred on Sky Mavis\' Ronin Blockchain, which resulted in the theft of over $600 million by North Korean threat actors. While North Korea is arguably the world\'s leading cyber criminal enterprise, they are not the only player. Since 2020, there have been hundreds of Web3 heists reported, which has resulted in over $12 billion in stolen digital assets

#### Targeted Industries - Financial Services ## Snapshot On August 19, 2024, Microsoft identified a North Korean threat actor exploiting a zero-day vulnerability in Chromium, now identified as [CVE-2024-7971](https://nvd.nist.gov/vuln/detail/CVE-2024-7971), to gain remote code execution (RCE). We assess with high confidence that the observed exploitation of CVE-2024-7971 can be attributed to a North Korean threat actor targeting the cryptocurrency sector for financial gain. Our ongoing analysis and observed infrastructure lead us to attribute this activity with medium confidence to [Citrine Sleet](https://security.microsoft.com/intel-profiles/740afa51582ebef367a7120efe99a535ba803f2169356580369a0fd680137145). We note that while the [FudModule](https://decoded.avast.io/janvojtesek/lazarus-and-the-fudmodule-rootkit-beyond-byovd-with-an-admin-to-kernel-zero-day/) rootkit deployed in the attack has also been attributed to [Diamond Sleet](https://security.microsoft.com/intel-profiles/b982c8daf198d93a2ff52b92b65c6284243aa6af91dda5edd1fe8ec5365918c5), another North Korean threat actor, Microsoft previously identified shared infrastructure and tools between Diamond Sleet and Citrine Sleet, and our analysis indicates this might be shared use of the FudModule malware between these threat actors. Google released a [fix for the vulnerability](https://chromereleases.googleblog.com/2024/08/stable-channel-update-for-desktop_21.html) on August 21, 2024, and users should ensure they are using the latest version of Chromium. Microsoft Defender for Endpoint detects Citrine Sleet activity with the alert *Emerging threat activity group Citrine Sleet detected*. To further protect from this kind of attack, organizations should ensure that Google Chrome and Microsoft Edge are updated and follow Microsoft\'s recommendations below in strengthening the endpoint. ## Activity Overview On August 19, 2024, Microsoft identified a North Korean threat actor exploiting an RCE exploit in the Chromium browser that has since been designated CVE-2024-7971. Entities that we identified who were targeted through this vector are associated with the cryptocurrency sector. One of these organizations is also a previous target of Sapphire Sleet. CVE-2024-7971 is a type confusion vulnerability in the V8 JavaScript and WebAssembly engine impacting versions of Chromium prior to 128.0.6613.84. Exploiting the vulnerability could allow threat actors to gain RCE in the sandboxed Chromium renderer process. Google released a fix for the vulnerability on August 21. CVE-2024-7971 is the third exploited V8 type confusion vulnerability that has been patched in V8 this year after [CVE-2024-4947](https://nvd.nist.gov/vuln/detail/CVE-2024-4947) and [CVE-2024-5274](https://nvd.nist.gov/vuln/detail/CVE-2024-5274). The attack used the typical stages seen in browser exploit chains. First, the targets were directed to the Citrine Sleet-controlled exploit domain *voyagorclub\[.\]space*. While we cannot confirm at this time how the targets were directed, social engineering is a common tactic used by Citrine Sleet. Once a target connected to the domain, the zero-day RCE exploit for CVE-2024-7971 was served. After the RCE exploit achieved code execution in the sandboxed Chromium renderer process, shellcode containing a Windows sandbox escape exploit and the FudModule rootkit was downloaded and then loaded into memory. The sandbox escape exploited [CVE-2024-38106](https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-38106), a vulnerability in the Windows kernel that Microsoft fixed on August 13, 2024, before we discovered this North Korean threat actor activity. CVE-2024-38106 was reported to Microsoft Security Response Center (MSRC) as being exploited; however, our investigations so far have not suggested any link between the reported CVE-2024-38106 exploit activity and this Citrine Sleet exploit activity, beyond exploiting the same vulnerability. This may suggest a "bug collision," where the same vulnerability is independentl | Malware Tool Vulnerability Threat | APT 38 | ★★ |

#### Targeted Geolocations - India - Korea - United States - Southeast Asia - North America #### Targeted Industries - Information Technology - Defense Industrial Base - Government Agencies & Services ## Snapshot On July 25, 2024, the United States Department of Justice (DOJ) indicted an individual linked to the North Korean threat actor that Microsoft tracks as Onyx Sleet. Microsoft Threat Intelligence collaborated with the Federal Bureau of Investigation (FBI) in tracking activity associated with Onyx Sleet. We will continue to closely monitor Onyx Sleet\'s activity to assess changes following the indictment. First observed by Microsoft in 2014, Onyx Sleet has conducted cyber espionage through numerous campaigns aimed at global targets with the goal of intelligence gathering. More recently, it has expanded its goals to include financial gain. This threat actor operates with an extensive set of custom tools and malware, and regularly evolves its toolset to add new functionality and to evade detection, while keeping a fairly uniform attack pattern. Onyx Sleet\'s ability to develop a spectrum of tools to launch its tried-and-true attack chain makes it a persistent threat, particularly to targets of interest to North Korean intelligence, like organizations in the defense, engineering, and energy sectors. Microsoft tracks campaigns related to Onyx Sleet and directly notifies customers who have been targeted or compromised, providing them with the necessary information to help secure their environments. ## Activity Overview ### Who is Onyx Sleet? Onyx Sleet conducts cyber espionage primarily targeting military, defense, and technology industries, predominately in India, South Korea, and the United States. This threat actor has historically leveraged spear-phishing as a means of compromising target environments; however, in recent campaigns, they have mostly exploited N-day vulnerabilities, leveraging publicly available and custom exploits to gain initial access. In October 2023, Onyx Sleet [exploited the TeamCity CVE-2023-42793 vulnerability](https://security.microsoft.com/intel-explorer/articles/b4f39b04) [as a part of a targeted attack](https://security.microsoft.com/vulnerabilities/vulnerability/CVE-2023-42793/overview). Exploiting this vulnerability enabled the threat actor to perform a remote code execution attack and gain administrative control of the server. Onyx Sleet develops and uses a spectrum of tools that range from custom to open source. They have built an extensive set of custom remote access trojans (RATs) that they use in campaigns, and routinely developed new variants of these RATs to add new functionality and implement new ways of evading detection. Onyx Sleet often uses leased virtual private servers (VPS) and compromised cloud infrastructure for command-and-control (C2). Onyx Sleet is tracked by other security companies as SILENT CHOLLIMA, Andariel, DarkSeoul, Stonefly, and TDrop2. **Affiliations with other threat actors originating from North Korea** Onyx Sleet has demonstrated affiliations with other North Korean actors, indicating its integration with a broader network of North Korean cyber operations. Microsoft has observed [an overlap](https://www.microsoft.com/en-us/security/blog/2022/07/14/north-korean-threat-actor-targets-small-and-midsize-businesses-with-h0lygh0st-ransomware/) between Onyx Sleet and [Storm-0530](https://www.microsoft.com/security/blog/2022/07/14/north-korean-threat-actor-targets-small-and-midsize-businesses-with-h0lygh0st-ransomware/). Both groups were observed operating within the same infrastructure and were involved in the development and use of ransomware in attacks in late 2021 and 2022. **Onyx Sleet targets** In pursuit of its primary goal of intelligence collection, Onyx Sleet has focused on targeting entities in the defense and energy industries, predominately in India, South Korea, and the United States.

Force Shadow est une menace qui cible les organisations sud-coréennes depuis 2013. Il cible principalement les serveurs Windows.Les chercheurs d'AHNLAB ont analysé l'activité du groupe en 2020-2022.Les activités de force fantôme sont relativement faciles à détecter car les acteurs ont tendance à réutiliser les mêmes noms de fichiers pour leurs logiciels malveillants.Dans le même temps, le groupe a évolué: après mars, ses fichiers dépassent souvent 10 Mo en raison de l'emballage binaire.Les acteurs ont également commencé à introduire divers mineurs de crypto-monnaie et une nouvelle porte dérobée surnommée Viticdoor.
Commentaire de l'analyste: Les organisations doivent garder leurs serveurs à jour et correctement configurés avec la sécurité à l'esprit.Une utilisation et une surchauffe du processeur inhabituellement élevées peuvent être un signe du détournement de ressources malveillantes pour l'exploitation de la crypto-monnaie.Les indicateurs basés sur le réseau et l'hôte associés à la force fantôme sont disponibles dans la plate-forme Anomali et il est conseillé aux clients de les bloquer sur leur infrastructure.

[Eye Opener] Should You Click on Unsubscribe?
By Roger A. Grimes.
Some common questions we get are "Should I click on an unwanted email's 'Unsubscribe' link? Will that lead to more or less unwanted email?"
The short answer is that, in general, it is OK to click on a legitimate vendor's unsubscribe link. But if you think the email is sketchy or coming from a source you would not want to validate your email address as valid and active, or are unsure, do not take the chance, skip the unsubscribe action.
In many countries, legitimate vendors are bound by law to offer (free) unsubscribe functionality and abide by a user's preferences. For example, in the U.S., the 2003 CAN-SPAM Act states that businesses must offer clear instructions on how the recipient can remove themselves from the involved mailing list and that request must be honored within 10 days.
Note: Many countries have laws similar to the CAN-SPAM Act, although with privacy protection ranging the privacy spectrum from very little to a lot more protection. The unsubscribe feature does not have to be a URL link, but it does have to be an "internet-based way." The most popular alternative method besides a URL link is an email address to use.
In some cases, there are specific instructions you have to follow, such as put "Unsubscribe" in the subject of the email. Other times you are expected to craft your own message. Luckily, most of the time simply sending any email to the listed unsubscribe email address is enough to remove your email address from the mailing list.

PyTorch Discloses Malicious Dependency Chain Compromise Over Holidays
(published: January 1, 2023)
Between December 25th and December 30th, 2022, users who installed PyTorch-nightly were targeted by a malicious library. The malicious torchtriton dependency on PyPI uses the dependency confusion attack by having the same name as the legitimate one on the PyTorch repository (PyPI takes precedence unless excluded). The actor behind the malicious library claims that it was part of ethical research and that he alerted some affected companies via HackerOne programs (Facebook was allegedly alerted). At the same time the library’s features are more aligned with being a malware than a research project. The code is obfuscated, it employs anti-VM techniques and doesn’t stop at fingerprinting. It exfiltrates passwords, certain files, and the history of Terminal commands. Stolen data is sent to the C2 domain via encrypted DNS queries using the wheezy[.]io DNS server.
Analyst Comment: The presence of the malicious torchtriton binary can be detected, and it should be uninstalled. PyTorch team has renamed the 'torchtriton' library to 'pytorch-triton' and reserved the name on PyPI to prevent similar attacks. Opensource repositories and apps are a valuable asset for many organizations but adoption of these must be security risk assessed, appropriately mitigated and then monitored to ensure ongoing integrity.

Alert (AA22-294A) #StopRansomware: Daixin Team
(published: October 21, 2022)
Daixin Team is a double-extortion ransomware group that has been targeting US businesses, predominantly in the healthcare sector. Since June 2022, Daixin Team has been encrypting electronic health record services, diagnostics services, imaging services, and intranet services. The group has exfiltrated personal identifiable information and patient health information. Typical intrusion starts with initial access through virtual private network (VPN) servers gained by exploitation or valid credentials derived from prior phishing. They use SSH and RDP for lateral movement and target VMware ESXi systems with ransomware based on leaked Babuk Locker source code.
Analyst Comment: Network defenders should keep organization’s VPN servers up-to-date on security updates. Enable multifactor authentication (MFA) on your VPN server and other critical accounts (administrative, backup-related, and webmail). Restrict the use of RDP, SSH, Telnet, virtual desktop and similar services in your environment.

Symantec detected a new custom data exfiltration tool used in a number of BlackByte ransomware attacks. This infostealer, dubbed Exbyte, performs anti-sandbox checks and proceeds to exfiltrate selected file types to a hardcoded Mega account. BlackByte ransomware-as-a-service operations were first uncovered in February 2022. The group’s recent attacks start with exploiting public-facing vulnerabilities of ProxyShell and ProxyLogon families. BlackByte removes Kernel Notify Routines to bypass Endpoint Detection and Response (EDR) products. The group uses AdFind, AnyDesk, Exbyte, NetScan, and PowerView tools and deploys BlackByte 2.0 ransomware payload.

This is a prime example of why it's important to always keep third-party PC manufacturer software, which is often neglected, up to date, as well as to add vulnerable versions to blocklists.“The most notable tool delivered by the attackers was a user-mode module that gained the ability to read and write kernel memory due to the CVE-2021-21551 vulnerability in a legitimate Dell driver,” security researchers from antivirus firm ESET said in a recent report. “This is the first ever recorded abuse of this vulnerability in the wild. The attackers then used their kernel memory write access to disable seven mechanisms the Windows operating system offers to monitor its actions, like registry, file system, process creation, event tracing etc., basically blinding security solutions in a very generic and robust way.”To read this article in full, please click here | Tool Vulnerability | APT 38 | |

2022-09-08 08:39:42 | Lazarus and the tale of three RATs (lien direct) |  By Jung soo An, Asheer Malhotra and Vitor Ventura.Cisco Talos has been tracking a new campaign operated by the Lazarus APT group, attributed to North Korea by the United States government. This campaign involved the exploitation of vulnerabilities in VMWare Horizon to gain an initial foothold into targeted organizations.Targeted organizations include energy providers from around the world, including those headquartered in the United States, Canada and Japan. The campaign is meant to infiltrate organizations around the world for establishing long term access and subsequently exfiltrating data of interest to the adversary's nation-state.Talos has discovered the use of two known families of malware in these intrusions - VSingle and YamaBot.Talos has also discovered the use of a recently disclosed implant we're calling "MagicRAT" in this campaign. IntroductionCisco Talos observed North Korean state-sponsored APT Lazarus Group conducting malicious activity between February and July 2022. Lazarus has been previously attributed to the North Korean government by the U.S. Cybersecurity and Infrastructure Security Agency (CISA). The entry vectors involve the successful exploitation of vulnerabilities in VMWare products to establish initial footholds into enterprise networks, followed by the deployment of the group's custom malware implants, VSingle and YamaBot. In addition to these known malware families, we have also discovered the use of a previously unknown malware implant we're calling "MagicRAT."This campaign was previously partially disclosed by other security firms, but our findings reveal more details about the adversary's modus operandi. We have also observed an overlap of command and control (C2) and payload-hosting infrastructure between our findings and the U.S. Cybersecurity and Infrastructure Security Agency's (CISA) June advisory that detailed continued attempts from threat actors to compromise vulnerable VMWare Horizon servers.In this research, we illustrate Lazarus Group's post-exploitation tactics, techniques and procedures (TTPs) to establish a foothold, perform initial reconnaissance, deploy bespoke malware and move laterally across infected enterprises. We also provide details about the activities performed by the attackers when the VSingle backdoor is instrumented on the infected endpoints.In this campaign, Lazarus was primarily targeting energy companies in Canada, the U.S. and Japan. The main goal of these attacks was likely to establish long-term access into victim networks to conduct espionage operations in support of North Korean govern |
