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 |

CryptBot | A typical infostealer, capable of obtaining credentials for browsers, crypto currency wallets, browser cookies, credit cards, and creates screenshots of the infected system. All stolen data is bundled into a zip-file that is uploaded to the c2. | No Attribution |

Nymaim | Nymaim is a trojan downloader. It downloads (and runs) other malware on affected systems and was one of the primary malware families hosted on Avalanche. Nymaim is different in that it displays a localized lockscreen while it downloads additional malware. Nymaim is usually delivered by exploit kits and malvertising. | 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 |
