About the Insomnia group

Insomnia is a data-theft and extortion group that emerged in October 2025, targeting primarily US-based healthcare organizations — stealing patient files and threatening public exposure rather than encrypting files — and avoiding former Soviet states, consistent with Russian-speaking cybercrime norms. Insomnia has listed 53 victims since February 2025.

Incident analysis

*********** was listed by Insomnia ransomware, a group with 59 victims recorded in this database. The listing appeared on the group's leak site on August 19, 2026.

*********** is based in United States. United States ranks #1 worldwide for ransomware disclosures, with 10,292 victims in this database.

Insomnia typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.
