Babuk | Babuk Ransomware is a sophisticated ransomware compiled for several platforms. Windows and ARM for Linux are the most used compiled versions, but ESX and a 32bit old PE executable were observed over time. as well It uses an Elliptic Curve Algorithm (Montgomery Algorithm) to build the encryption keys. | No Attribution |

STOP, Djvu | STOP Djvu Ransomware it is a ransomware which encrypts user data through AES-256 and adds one of the dozen available extensions as marker to the encrypted file's name. It is not used to encrypt the entire file but only the first 5 MB. In its original version it was able to run offline and, in that case, it used a hard-coded key which could be extracted to decrypt files. | No Attribution |

Glupteba | Glupteba is a trojan horse malware that is one of the top ten malware variants of 2021. After infecting a system, the Glupteba malware can be used to deliver additional malware, steal user authentication information, and enroll the infected system in a cryptomining botnet. | No Attribution |

RedLine Stealer | RedLine Stealer is a malware available on underground forums for sale apparently as standalone ($100/$150 depending on the version) or also on a subscription basis ($100/month). This malware harvests information from browsers such as saved credentials, autocomplete data, and credit card information. A system inventory is also taken when running on a target machine, to include details such as the username, location data, hardware configuration, and information regarding installed security software. More recent versions of RedLine added the ability to steal cryptocurrency. FTP and IM clients are also apparently targeted by this family, and this malware has the ability to upload and download files, execute commands, and periodically send back information about the infected computer. | No Attribution |

SmokeLoader | The SmokeLoader family is a generic backdoor with a range of capabilities which depend on the modules included in any given build of the malware. The malware is delivered in a variety of ways and is broadly associated with criminal activity. The malware frequently tries to hide its C2 activity by generating requests to legitimate sites such as microsoft.com, bing.com, adobe.com, and others. Typically the actual Download returns an HTTP 404 but still contains data in the Response Body. |
