D4rk4rmy ransomware group
D4rk4rmy 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 1y ago.
Who they are
D4rk4rmy is a data-extortion focused threat actor that emerged in mid-2025, targeting high-profile organizations across sectors like financial services, hospitality, and education. It operates primarily through leak site extortion rather than encryption, listing prominent entities—such as Bridgewater Associates, Magellan Financial, Onex Canada Asset Management, Tsai Capital, Casino de Monte-Carlo, and others—on its Tor-based platform. The group has also hit victims in technology, logistics, and university sectors across multiple continents. Their tactic centers on reputation manipulation and public exposure to pressure victims into negotiations.
Current status
D4rk4rmy'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 1y ago (30 Aug 2025 14:15 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 D4rk4rmy 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.
