(lien direct)	CyberheistNews Vol 13 #09 \| February 28th, 2023 [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.

Trending Cyber News and Threat Intelligence 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.

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.

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.

WannaCry is a ransomware worm that spread rapidly through across a number of computer networks in May of 2017. After infecting a Windows computer, it encrypts files on the PC's hard drive, making them impossible for users to access, then demands a ransom payment in bitcoin in order to decrypt them.A number of factors made the initial spread of WannaCry particularly noteworthy: it struck a number of important and high-profile systems, including many in Britain's National Health Service; it exploited a Windows vulnerability that was suspected to have been first discovered by the United States National Security Agency; and it was tentatively linked by Symantec and other security researchers to the Lazarus Group, a cybercrime organization that may be connected to the North Korean government.To read this article in full, please click here	Ransomware Vulnerability Medical	Wannacry Wannacry APT 38

Trending Cyber News and Threat Intelligence APT-C-35: New Windows Framework Revealed (published: August 11, 2022) The DoNot Team (APT-C-35) are India-sponsored actors active since at least 2016. Morphisec Labs researchers discovered a new Windows framework used by the group in its campaign targeting Pakistani government and defense departments. The attack starts with a spearphishing RTF attachment. If opened in a Microsoft Office application, it downloads a malicious remote template. After the victim enables editing (macroses) a multi-stage framework deployment starts. It includes two shellcode stages followed by main DLL that, based on victim fingerprinting, downloads a custom set of additional information-stealing modules. Analyst Comment: The described DoNot Team framework is pretty unique in its customisation, fingerprinting, and module implementation. At the same time, the general theme of spearphishing attachment that asks the targeted user to enable editing is not new and can be mitigated by anti-phishing training and Microsoft Office settings hardening.

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

Trending Cyber News and Threat Intelligence Lazarus Targets Chemical Sector (published: April 14, 2022) In January 2022, Symantec researchers discovered a new wave of Operation Dream Job. This operation, attributed to the North Korea-sponsored group Lazarus, utilizes fake job offers via professional social media and email communications. With the new wave of attacks, Operation Dream Job switched from targeting the defense, government, and engineering sectors to targeting South Korean organizations operating within the chemical sector. A targeted user executes an HTM file sent via a link. The HTM file is copied to a DLL file to be injected into the legitimate system management software. It downloads and executes the final backdoor: a trojanized version of the Tukaani project LZMA Utils library (XZ Utils) with a malicious export added (AppMgmt). After the initial access, the attackers gain persistence via scheduled tasks, move laterally, and collect credentials and sensitive information. Analyst Comment: Organizations should train their users to recognize social engineering attacks including those posing as “dream job” proposals. Organizations facing cyberespionage threats should implement a defense-in-depth approach: layering of security mechanisms, redundancy, fail-safe defense processes.

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.

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.

Trending Cyber News and Threat Intelligence Grindr Fixed a Bug Allowing Full Takeover of Any User Account (published: October 3, 2020) Grindr, an LGBT networking platform, has fixed a vulnerability that could allow any account to be hijacked. The vulnerability was identified by security researcher Wassime Bouimadaghene, finding that the reset token was leaked in the page’s response content. This would enable anyone who knows a users’ email address to generate the reset link that is sent via email. Gaining account access would enable an attacker to obtain sensitive information such as pictures stored on the app (including NSFW), HIV status, location, and messages. Grindr has announced a bug bounty program. Recommendation: If your account has been breached, you can reset the password using the reset link sent to the associated email address. Tags: Browser, Exposed tokens, Grindr, Sensitive Info XDSpy: Stealing Government Secrets Since 2011 (published: October 2, 2020) Security researchers from ESET have identified a new Advanced Persistent Threat (APT) group that has been targeting Eastern European governments and businesses for up to nine years. Dubbed “XDSpy,” ESET was unable to identify any code similarity or shared infrastructure with other known groups and believe the group operates in a UTC+2 or UTC+3 time zone, Monday to Friday. XDSpy mainly uses spearphishing emails with some variance, some will contain attachments or links to malicious files, usually a ZIP or RAR archive. When the malicious file has infected a victim, it will install “XDDown,” a downloader that will begin to install additional plugins that will begin to exfiltrate files, passwords, and nearby SSIDs. XDSpy has also been observed using “CVE-2020-0968” (Internet Explorer legacy JavaScript vulnerability) bearing some resemblance to DarkHotel campaigns and Operation Domino, ESET do not believe these campaigns are related but may be using the same exploit broker. Recommendation: 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. Furthermore, all employees should be educated on the risks of spearphishing and how to identify such attempts.

Trending Cyber News and Threat Intelligence ‘Baka’ Javascript Skimmer Identified (published: September 6, 2020) Visa have issued a security alert based on identification of a new skimmer, named “Baka”. Based on analysis by Visa Payment Fraud Disruption, the skimmer appears to be more advanced, loading dynamically and using an XOR cipher for obfuscation. The attacks behind Baka are injecting it into checkout pages using a script tag, with the skimming code downloading from the Command and Control (C2) server and executing in memory to steal customer data. Recommendation: eCommerce site owners must take every step necessary to secure their data and safeguard their payment card information. Visa has also released best practices in the security advisory.

After receiving many tech support calls, the computer networks were shut down to prevent further spread of the ransomware, which led to a cecission in border crossings until systems were up again. The ransomware used in this attack is Netwalker ransomware, that left a ransom note demanding initalling $2 million, however when this wasn’t paid in the first week, the ransom increased to $4 million. Recommendation: Ransomware can potentially be blocked by using endpoint protection solutions (HIDS). Always keep your important files backed up following the 3-2-1 rule: have at least 3 different copies, on 2 different mediums, with 1 off-site. In the case of ransomware infection, the affected system must be wiped and reformatted. Other devices on the network should be checked for similar infections. Always check for a decryptor before considering payment; avoid payment at all costs. Ransomware should be reported to law enforcement agencies who are doing their best to track these actors and prevent ransom from being a profitable business for cyber criminals. MITRE ATT&CK: [MITRE ATT&CK] Data Encrypted for Impact - T1486 Tags: Argentina, Government, Netwalker, Ransomware No Rest for the Wicked: Evilnum Unleashes PyVil RAT (published: September 3, 2020) Researchers on the Cybereason Nocturnus team have published their research tracking the threat actor group known as Evilnum, and an ongoing change in their tooling and attack procedures.

Whilst ActiveX controls are disabled on most systems, they are still enabled on most South Korean machines due to mandates by the South Korean government. These attacks have been attributed to Lazarus, a group thought to be linked to North Korea. Below we’ve shared our brief analysis of of the attack. Profiling Script The first step appears to have been a profiling script to get information on possible targets for their attack. We’ve seen Lazarus do this before on other sites they have infected, and it’s a technique that other advanced attackers have been seen to employ. This was followed by scripts to perform additional profiling and actually delivery the ActiveX exploit. Some details of these scripts were kindly shared by issuemakerslab, who identified a number of infections that moved over time:	Malware Vulnerability	APT 38	★★★★
