Haron ransomware group
Haron 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 4y ago.
Who they are
Haron is a ransomware group that emerged in July 2021 and is believed to share operational similarities with the Avaddon ransomware, which shut down the month prior. Haron uses a double-extortion model—encrypting victims’ data and threatening to publish stolen files on a Tor-based leak site. The ransomware is written in C# and uses the Salsa20 encryption algorithm with RSA-1024 for key protection. File extensions are typically not changed during encryption, but ransom notes named HOW TO RESTORE YOUR FILES.txt are dropped across affected systems. Initial access methods are not comprehensively documented in public sources but may include phishing campaigns and exploitation of exposed RDP services. Haron’s leak site and negotiation structure closely resemble Avaddon’s, suggesting either code reuse or a shared affiliate network.
Current status
Haron'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 4y ago (15 Apr 2022 03:07 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 Haron 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.
