Incident Analysis

Stockham Construction was targeted by Storm ransomware, one of the most active ransomware groups in our database with 78 confirmed victims globally. The attack was disclosed on September 30, 2026, when Stockham Construction appeared on the group's dark web leak site.

Stockham Construction is based in United States , operating in the Manufacturing sector. United States ranks #1 globally for ransomware attacks, with 9,656 victims in our database.

Sector context: Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

Storm 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.
