Arvinclub ransomware group
Arvinclub 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
Arvin Club first appeared around early to mid-2021, debuting on its Tor leak site with posts dating back to May 5, 2021. While frequently characterized as ransomware, there is no verified evidence of file encryption or RaaS operations—its behavior aligns more closely with data-leak and hacktivist activity. The group actively publishes stolen data via its Onion site and maintains a prominent presence on Telegram, operating both official channels and group chats (notably with Persian-language content). A known target includes India's Kendriya Vidyalaya school network among others. Arvin Club has shown ideological leanings (notably support for REvil) and claims to have “hacktivist” motivations, including activities against the Iranian regime. No encryption algorithms, file extensions, or ransom notes have been publicly documented.
Current status
Arvinclub'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 (6 Nov 2023 04:08 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 Arvinclub 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.
