Loading threat actor…
Insomnia is a ransomware and extortion threat actor known to publicly claim intrusions by naming victims on a data leak site. The group has been linked to the compromise of a U.S. clinical laboratory, where unauthorized access reportedly led to theft of sensitive personal and protected health information. Publicly observed behavior supports the use of data-theft extortion and operation of a leak site. Available high-confidence reporting does not establish additional technical tradecraft, sub-groups, or a confirmed national affiliation.
