Lumma Stealer, LummaC2 Stealer | Lumma Stealer (aka LummaC2 Stealer) is an information stealer written in C language that has been available through a Malware-as-a-Service (MaaS) model on Russian-speaking forums since at least August 2022. It is believed to have been developed by the threat actor "Shamel", who goes by the alias "Lumma". Lumma Stealer primarily targets cryptocurrency wallets and two-factor authentication (2FA) browser extensions, before ultimately stealing sensitive information from the victim's machine. Once the targeted data is obtained, it is exfiltrated to a C2 server via HTTP POST requests using the user agent "TeslaBrowser/5.5"." The stealer also features a non-resident loader that is capable of delivering additional payloads via EXE, DLL, and PowerShell. | No Attribution |

Amadey | Amadey is a botnet that appeared around October 2018 and is being sold for about $500 on Russian-speaking hacking forums. It periodically sends information about the system and installed AV software to its C2 server and polls to receive orders from it. Its main functionality is that it can load other payloads (called "tasks") for all or specifically targeted computers compromised by the malware. | No Attribution |

Stealc | Stealc is an information stealer advertised by its presumed developer Plymouth on Russian-speaking underground forums and sold as a Malware-as-a-Service since January 9, 2023. According to Plymouth's statement, stealc is a non-resident stealer with flexible data collection settings and its development is relied on other prominent stealers: Vidar, Raccoon, Mars and Redline.Stealc is written in C and uses WinAPI functions. It mainly targets date from web browsers, extensions and Desktop application of cryptocurrency wallets, and from other applications (messengers, email clients, etc.). The malware downloads 7 legitimate third-party DLLs to collect sensitive data from web browsers, including sqlite3.dll, nss3.dll, vcruntime140.dll, mozglue.dll, freebl3.dll, softokn3.dll and msvcp140.dll. It then exfiltrates the collected information file by file to its C2 server using HTTP POST requests. | No Attribution |
