Ciphbit ransomware group
Ciphbit 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 12h ago.
Who they are
CiphBit is a crypto-ransomware first detected in April 2023. It utilizes a double-extortion model, encrypting files and threatening to leak stolen data via a Tor-hosted portal if ransom demands are not met. The malware appends encrypted files with a vector including a unique victim ID, the attacker’s email address (onionmail.org), and a four-character random extension—making file identification and recovery especially difficult. Victims span various sectors including banking, manufacturing, healthcare, logistics, and professional services across North America and Europe. The group is classified as a data broker due to its evolving extortion methods involving free leaks and selective leaks to pressure victims. Recent high-profile victims include iptelecom GmbH (Germany) and Therma Seal Insulation Systems (USA), reaffirming its cross-industry reach and impact.
Current status
Ciphbit'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.
The last change we recorded on it was 12h ago (20 Oct 2026 18:16 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 Ciphbit 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.
