Raspberry Robin Malware Targets Telecom, Governments
We found samples of the Raspberry Robin malware spreading in telecommunications and government office systems beginning September. The main payload itself is packed with more than 10 layers for obfuscation and is capable of delivering a fake payload once it detects sandboxing and security analytics tools.
From mid-June through mid-July 2022, CISA conducted an incident response engagement at a Federal Civilian Executive Branch (FCEB) organization where CISA observed suspected advanced persistent threat (APT) activity. In the course of incident response activities, CISA determined that cyber threat actors exploited the Log4Shell vulnerability in an unpatched VMware Horizon server, installed XMRig crypto mining software, moved laterally to the domain controller (DC), compromised credentials, and then implanted Ngrok reverse proxies on several hosts to maintain persistence.
The offensive macOS cyber capabilities of the WINDSHIFT APT group provide us with the opportunity to gain insight into the Apple-specific approaches employed by an advanced adversary. In this talk we’ll comprehensively dissect OSX.WindTape, a second-stage tool utilized by the WINDSHIFT APT group when targeting Apple systems. First we’ll discuss the malware’s anti-analysis mechanisms, and then once these have been thwarted, we’ll explore its capabilities. To conclude, we’ll present heuristic methods that can generically both detect and prevent WindTape, as well as other advanced macOS threats.
Our recent investigation at Certfa Lab, the APT42 has been running multiple phishing campaigns since late 2021 and some of them are ongoing and still active.
Kimsuky’s GoldDragon cluster and its C2 operations | Securelist
Kimsuky is a prolific and active threat actor primarily targeting Korea-related entities. In early 2022, we observed this group was attacking the media and a think-tank in South Korea.
Justice Department seizes $500K from North Korean hackers who targeted US medical organizations
The US Justice Department seized approximately half a million dollars that North Korean government-backed hackers had either extorted from US health care organizations or used to launder ransom payments, deputy Attorney General Lisa Monaco said Tuesday as she touted an aggressive US strategy to claw back money for victims of ransomware attacks.
China: Declaration by the Minister for Foreign Affairs on behalf of the Belgian Government urging Chinese authorities to take action against malicious cyber activities undertaken by Chinese actors

Why the Equation Group (EQGRP) is NOT the NSA | xorl %eax, %eax
I had covered this topic in my 2021 talk “In nation-state actor’s shoes” but after my recent blog post I saw again people referring to the EQGRP as the NSA which is not entirely c…
When Pentest Tools Go Brutal: Red-Teaming Tool Being Abused by Malicious Actors
Unit 42 continuously hunts for new and unique malware samples that match known advanced persistent threat (APT) patterns and tactics. On May 19, one such sample was uploaded to VirusTotal, where it received a benign verdict from all 56 vendors that evaluated it. Beyond the obvious detection concerns, we believe this sample is also significant in terms of its malicious payload, command and control (C2), and packaging.
The SessionManager IIS backdoor: a possibly overlooked GELSEMIUM artefact
In early 2022, we investigated an IIS backdoor called SessionManager. It has been used against NGOs, government, military and industrial organizations in Africa, South America, Asia, Europe, Russia and the Middle East.
Unveiling an unknown APT actor attacking high-profile entities in Europe and Asia ToddyCat is a relatively new APT actor that we have not been able to relate to other known actors, responsible for multiple sets of attacks detected since December 2020 against high-profile entities in Europe and Asia. We still have little information about this actor, but we know that its main distinctive signs are two formerly unknown tools that we call ‘Samurai backdoor’ and ‘Ninja Trojan’.
BRATA is evolving into an Advanced Persistent Threat
Here we go with another episode about our (not so) old friend, BRATA. In almost one year, threat actors (TAs) have further improved the capabilities of this malware. In our previous blog post [1] we defined three main BRATA variants, which appeared during two different waves detected by our telemetries at the very end of 2021. However, during the last months we have observed a change in the attack pattern commonly used.
From the Front Lines | Unsigned macOS oRAT Malware Gambles For The Win
Researchers looking into a new APT group targeting gambling sites with a variety of cross-platform malware recently identified a version of oRAT malware targeting macOS users and written in Go. While neither RATs nor Go malware are uncommon on any platform, including the Mac, the development of such a tool by a previously unknown APT is an interesting turn, signifying the increasing need for threat actors to address the rising occurrence of Macs among their intended targets and victims. In this post, we dig deeper into the technical details of this novel RAT to understand better how it works and how security teams can detect it in their environments.
Operation CuckooBees: Cybereason Uncovers Massive Chinese Intellectual Property Theft Operation
Cybereason recently an attack assessed to be the work of Chinese APT Winnti that operated undetected, siphoning intellectual property and sensitive data - the two companion reports examine the tactics and techniques of the overall campaign as well as more detailed analysis of the malware arsenal and exploits used...
Iranian linked conglomerate MuddyWater comprised of regionally focused subgroups
Cisco Talos has observed new cyber attacks targeting Turkey and other Asian countries we believe with high confidence are from groups operating under the MuddyWater umbrella of APT groups. U.S. Cyber Command recently connected MuddyWater to Iran's Ministry of Intelligence and Security (MOIS).
Asylum Ambuscade: State Actor Uses Compromised Private Ukrainian Military Emails to Target European Governments and Refugee Movement
Proofpoint has identified a likely nation-state sponsored phishing campaign using a possibly compromised Ukrainian armed service member’s email account to target European government personnel involved in managing the logistics of refugees fleeing Ukraine. * The email included a malicious macro attachment which attempted to download a Lua-based malware dubbed SunSeed. * The infection chain used in this campaign bears significant similarities to a historic campaign Proofpoint observed in July 2021, making it likely the same threat actor is behind both clusters of activity. * Proofpoint is releasing this report in an effort to balance accuracy with responsibility to disclose actionable intelligence during a time of high-tempo conflict.
ZINC weaponizing open-source software - Microsoft Security Blog
In recent months, Microsoft has detected a wide range of social engineering campaigns using weaponized legitimate open-source software by an actor we track as ZINC. Microsoft Threat Intelligence Center (MSTIC) observed activity targeting employees in organizations across multiple industries including media, defense and aerospace, and IT services in the US, UK, India, and Russia. Based on the observed tradecraft, infrastructure, tooling, and account affiliations, MSTIC attributes this campaign with high confidence to ZINC, a state-sponsored group based out of North Korea with objectives focused on espionage, data theft, financial gain, and network destruction.
