ThreatAI Analysis

Compiled from this incident record and the threat intelligence profile for Insomnia. Figures and technique mappings are quoted from the source data, not inferred.

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 49 victims since February 2025.

Incident Analysis

The Syverson Group was targeted by Insomnia ransomware, one of the most active ransomware groups in our database with 52 confirmed victims globally. The attack was disclosed on February 13, 2026, when The Syverson Group appeared on the group's dark web leak site.

The Syverson Group is based in United States , operating in the Business Services sector. United States ranks #1 globally for ransomware attacks, with 9,567 victims in our database.

Sector context: Business services firms often have access to multiple client environments, making them high-value pivot points for ransomware operators seeking to maximise impact across multiple victim organisations.

Insomnia typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.
