What Happened?
On August 25th, 2026, Ransomware.live reported that the ransomware group Dark Project added Pump Engineering Company to its dark-web leak site. According to the attacker’s unverified claim, approximately 120,000 files totaling 115 GB were stolen. Dark Project alleges that the stolen data includes a customer database, insurance documents, confidential financial documents, and a large number of project drawings. These data categories are attacker-side allegations only and have not been confirmed by Pump Engineering Company or any independent source such as a regulatory filing or news report. No corroborating sources were found.
Ransomware.live itself flags Dark Project as an emerging group and advises that its claims should be treated with caution until independently verified. Threat intelligence sources describe Dark Project as a financially motivated ransomware and data-extortion operation first publicly observed in August 2026. Security researchers note that the group’s victim selection appears consistent with opportunistic, affiliate-driven targeting of mid-market organizations. No prior data breaches involving Pump Engineering Company were identified, and no litigation related to this incident has been reported.
