Antibrok3rs ransomware group
Antibrok3rs 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 17h ago.
Who they are
Antibrok3rs emerged as an access broker (not a ransomware operator itself) linked to the aftermath of the 2023 MOVEit supply-chain exploitation. From November 2024 through early 2025, this actor has posted stolen data from at least 15 energy-sector victims, including U.S. utilities such as CenterPoint Energy, Entergy, Nevada Energy, and Appalachian Power—data likely obtained via the MOVEit breach. While some analysts suspected ties to the Cl0P ransomware collective, Antibrok3rs publicly denied any such affiliation. The extortion model centers on data leakage without accompanying file encryption—a purely leak-based threat. No delivery, encryption, or ransom note behaviors have been observed, nor is there evidence of RaaS activity.
Current status
Antibrok3rs's leak site is answering our checks. That does not mean the group is actively posting — plenty of sites stay up for months with nothing new on them — but the infrastructure is live.

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 Antibrok3rs 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.
