BlackWorm Ransomware is a malicious computer infection that encrypts your files, and then does everything it can to prevent you from restoring them. It needs you to pay $200 for the decryption key, but there is no guarantee that the people behind this infection would really issue the decryption tool for you.

The operators of the ALPHV/BlackCat ransomware began their activity in December 2021, making posts on Dark Web forums to promote their affiliate program, offering other actors the opportunity to engage in a 'new type of ransomware family' developed from scratch using the Rust programming language.<BR> <BR> Some clear evidence indicates that the actors behind this new ransomware are not new to cybercrime, and there were links to other affiliate programs such as DarkSide, BlackMatter, and REvil. (After several attacks against large companies, these groups faced pressure and arrests, necessitating the termination of their operations).<BR> <BR> As a security measure, the operators of ALPHV implemented the requirement for the execution of the ransomware payload by providing an 'access token,' which is supplied by the owners of the Ransomware-as-a-Service to the affiliate. This token is added to the victim's ransom note so that they can contact the threat actor responsible for encrypting the data.<BR> <BR> ALPHV affiliates employ double and triple extortion techniques, meaning the publication of the company's name on leak sites, threats of data leakage, and lastly, threats of DDoS attacks against the organization.<BR>Source: https://github.com/crocodyli/ThreatActors-TTPs

AiLock is a Ransomware-as-a-Service (RaaS) group first identified in March 2025. It employs a double-extortion approach—encrypting files and threatening to report breaches to regulators or share stolen data with competitors if the ransom isn’t paid. Victims have just 72 hours to respond and up to five days to pay; failure to pay results in data leaks and destruction of recovery tools. The ransomware appends the extension .AiLock to encrypted files, changes file icons to a green padlock with the “AiLock” name, and replaces the desktop wallpaper with a distinctive robot-skull logo. It employs a hybrid encryption scheme, combining ChaCha20 for file encryption with NTRUEncrypt for securing metadata, and uses a multi-threaded design (path-traversal and encryption threads with IOCP) for efficiency. While active campaigns and leak sites are confirmed, specific sectors, regions, and intrusion methods remain undisclosed in public sources.
