Group profile
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.
