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 |

Vidar | Vidar is a forked malware based on Arkei. It seems this stealer is one of the first that is grabbing information on 2FA Software and Tor Browser. | No Attribution |

xmrig | According to PCrisk, XMRIG is a completely legitimate open-source application that utilizes system CPUs to mine Monero cryptocurrency. Unfortunately, criminals generate revenue by infiltrating this app into systems without users' consent. This deceptive marketing method is called "bundling".In most cases, "bundling" is used to infiltrate several potentially unwanted programs (PUAs) at once. So, there is a high probability that XMRIG Virus came with a number of adware-type applications that deliver intrusive ads and gather sensitive information. | No Attribution |
