Donex ransomware group
Donex is one of the extortion operations we watch continuously. This page covers what is known about the group and the current state of its leak site, which we last saw change 3y ago.
Who they are
Donex is a ransomware family that emerged in early 2022 as a rebrand of the older Muse ransomware. It uses a double-extortion strategy, combining file encryption with threats to leak stolen data on a Tor-hosted portal. Written in C++, Donex encrypts files using a combination of ChaCha20 and RSA-4096 algorithms and appends a custom extension unique to each victim. The group targets a broad range of sectors, including manufacturing, logistics, and professional services, with victims reported across North America, Europe, and Asia. Initial access methods include exploitation of public-facing applications and the use of stolen RDP credentials.
Current status
Donex's leak site is not answering. Sites go dark for infrastructure trouble, a deliberate quiet period, or a takedown, and a good number return weeks later under the same name, so the entry stays on the list either way.
The last change we recorded on it was 3y ago (2 Apr 2024 13:18 UTC).
Which organisations this group has named, and when, is part of the SINON platform rather than this page. Create an account to search it, or to be told automatically if a name you care about turns up.
Sectors targeted
This group does not state an industry on its site, so we have nothing reliable to report. Most crews are opportunistic rather than sector-specific in any case — they hit what they can reach.
Watching for your name
If Donex posts your company, a supplier or a subsidiary, you want to hear it from us rather than from a journalist. SINON checks these sites continuously and alerts on the names you give it.
