Chaos began in 2021 as a low-cost, builder-based Windows ransomware whose code was influenced by the older Dharma family; early builds were reportedly written in AutoIt with later versions in C/C++ (vendor research, 2021). A distinct 'Chaos' extortion brand operating a public leak site has been active since 2022 and became one of the more prolific name-and-shame posters, frequently listing small and mid-sized victims, sometimes in high volumes. In 2024, the FBI issued a FLASH advisory on Chaos ransomware, reflecting continued use of the strain against victims. Initial access is widely reported to rely on exposed remote-access services with weak or stolen credentials and phishing rather than a single exploited vulnerability. The group's country of origin, estimated earnings, and the precise relationship between the original builder family and the current leak-site brand are not definitively established (unknown).
Tactics & tooling
- Initial access via exposed RDP/VPN services with weak or stolen credentials (widely reported)
- Phishing-delivered ransomware and loader campaigns
- Dharma-influenced encryptor; partial encryption of large files
- Renames files with random names/extensions and drops a readme.txt ransom note (documented in early-family analyses)
- Deletes volume shadow copies to hinder recovery
- Cheap ransomware-as-a-service builder spawned many derivative builds, complicating attribution
- Data-theft extortion with public leak-site posts, sometimes mass-posting victims
