Classification

Name Description Attribution Blogpost URLs Link
Agent Tesla, AgentTesla A .NET based information stealer readily available to actors due to leaked builders. The malware is able to log keystrokes, can access the host's clipboard and crawls the disk for credentials or other valuable information. It has the capability to send information back to its C&C via HTTP(S), SMTP, FTP, or towards a Telegram channel.

Name Description Attribution Blogpost URLs Link
DarkTortilla DarkTortilla is a complex and highly configurable .NET-based crypter that has possibly been active since at least August 2015. It typically delivers popular information stealers and remote access trojans (RATs) such as AgentTesla, AsyncRat, NanoCore, and RedLine. While it appears to primarily deliver commodity malware, Secureworks Counter Threat Unit (CTU) researchers identified DarkTortilla samples delivering targeted payloads such as Cobalt Strike and Metasploit. It can also deliver "addon packages" such as additional malicious payloads, benign decoy documents, and executables. It features robust anti-analysis and anti-tamper controls that can make detection, analysis, and eradication challenging.From January 2021 through May 2022, an average of 93 unique DarkTortilla samples per week were uploaded to the VirusTotal analysis service. Code similarities suggest possible links between DarkTortilla and other malware: a crypter operated by the RATs Crew threat group, which was active between 2008 and 2012, and the Gameloader malware that emerged in 2021.
