Photo by Matheus Queiroz on Unsplash In late 2022 we decided to start monitoring PyPI, arguably the most important Python repository, as there were a number of reports on it hosting malware. PyPI took exceptional relevance amongst all repositories as, historically, it was trusted by default by many software developers. Any security breach or abuse […] more…Deception at scale: How attackers abuse governmental infrastructure
Continuing our initiative of sharing VirusTotal’s visibility to help researchers, security practitioners and the general public better understand the nature of malicious attacks, we are proud to announce our “Deception at scale: How attackers abuse governmental infrastructure” report. Here are some of the main ideas presented there: Governmental domains are among the top categories used […] more…57 Million Users Compromised in Uber Leak: Protect Your Digital Privacy and Identity
“I’ll just Uber home.” Who hails a taxi anymore? These days, city streets are full of double-parked sedans with their hazards on, looking for their charges. Uber is synonymous with ridesharing and has made it so far into our culture that it’s not just a company name but a verb. Uber’s reputation has ebbed and […] more…MoonBounce: the dark side of UEFI firmware

At the end of 2021, we were made aware of a UEFI firmware-level compromise through logs from our Firmware Scanner, which has been integrated into Kaspersky products since the beginning of 2019. Further analysis has shown that a single component within the inspected firmware’s image was modified by attackers in a way that […] more…ScarCruft surveilling North Korean defectors and human rights activists
The ScarCruft group (also known as APT37 or Temp.Reaper) is a nation-state sponsored APT actor we first reported in 2016. ScarCruft is known to target North Korean defectors, journalists who cover North Korea-related news and government organizations related to the Korean Peninsula, between others. Recently, we were approached by a news organization with a request […] more…Trickbot module descriptions
Trickbot (aka TrickLoader or Trickster), is a successor of the Dyre banking Trojan that was active from 2014 to 2016 and performed man-in-the-browser attacks in order to steal banking credentials. Trickbot was first discovered in October 2016. Just like Dyre, its main functionality was initially the theft of online banking data. However, over time, its […] more…Ransomware in the CIS
Introduction These days, when speaking of cyberthreats, most people have in mind ransomware, specifically cryptomalware. In 2020–2021, with the outbreak of the pandemic and the emergence of several major cybercriminal groups (Maze, REvil, Conti, DarkSide, Avaddon), an entire criminal ecosystem took shape, leading to a mounting worldwide wave of attacks on large organizations with pockets […] more…Detection evasion in CLR and tips on how to detect such attacks
In terms of costs, the age-old battle that pits attacker versus defender has become very one sided in recent years. Almost all modern attacks (and ethical offensive exercises) use Mimikatz, SharpHound, SeatBelt, Rubeus, GhostPack and other toolsets available to the community. This so-called githubification is driving attackers’ costs down and reshaping the focus from malware […] more…APT10: sophisticated multi-layered loader Ecipekac discovered in A41APT campaign
Why is the campaign called A41APT? In 2019, we observed an APT campaign targeting multiple industries, including the Japanese manufacturing industry and its overseas operations, that was designed to steal information. We named the campaign A41APT (not APT41) which is derived from the host name “DESKTOP-A41UVJV” from the attacker’s system used in the initial infection.

FireEye did not link this activity to any known actor; […] more…Dox, steal, reveal. Where does your personal data end up?

Every year the online and offline spheres have become more and more connected and are now completely intertwined, leading to online actions having real consequences in the physical realm — both good and […] more…An overview of targeted attacks and APTs on Linux
Perhaps unsurprisingly, a lot has been written about targeted attacks on Windows systems. Windows is, due to its popularity, the platform for which we discover most APT attack tools. At the same time, there’s a widely held opinion that Linux is a secure-by-default operating system that isn’t susceptible to malicious code. It’s certainly true that […] more…Transparent Tribe: Evolution analysis,part 1
Background and key findings Transparent Tribe, also known as PROJECTM and MYTHIC LEOPARD, is a highly prolific group whose activities can be traced as far back as 2013.
