Incident Analysis

Cosmon was targeted by Beast ransomware, one of the most active ransomware groups in our database with 72 confirmed victims globally. The attack was disclosed on August 25, 2026, when Cosmon appeared on the group's dark web leak site.

Cosmon is based in United States , operating in the Technology sector. United States ranks #1 globally for ransomware attacks, with 9,420 victims in our database.

Sector context: Technology companies hold intellectual property, customer data, and source code β€” all highly valuable assets. A successful ransomware attack can also put downstream customers at risk through supply chain exposure.

Beast 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 β€” 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.
