Pump Engineering Company Data Breach

Pump Engineering Company, a US-based industrial manufacturer specializing in pump systems, engineering, distribution, and service for fluid management applications, was added to the Dark Project ransomware group’s leak site on August 25, 2026. This listing was identified through SOCRadar’s Dark Web Monitoring. The inclusion of Pump Engineering Company highlights the group’s continued targeting of the American manufacturing sector, which consistently appears on Dark Project’s list of victims. In the 60 days preceding this listing, Dark Project claimed 25 other victims. The group’s primary targets by sector are Manufacturing, Healthcare, and Transportation. Geographically, the United States is the most frequently targeted country, followed by the United Kingdom and the Philippines. Recent victims with similar profiles to Pump Engineering Company include Design-Aire Engineering INC, Rocky Mount Recyclers, Leviton, and Mayco International. This indicates that US industrial manufacturers are a deliberate and primary targeting category for Dark Project, rather than an incidental one.

A query was performed against stealer-log data for the domain pumpengineering[.]net. The query returned no records. It is important to note that this dataset is paginated and sampled, meaning that credentials may exist in other data feeds not covered by this specific query. Furthermore, credentials could still exist under alternative corporate domains or be associated with employee personal email aliases. The absence of records in this specific stealer-log query does not rule out the possibility of a compromise. Infostealer logs are a common tool for ransomware operators to gain initial access. Threat actors or brokers often harvest and validate corporate credentials from these logs, which are then used to access systems via platforms like Microsoft 365 or VPN portals before deploying ransomware. Therefore, a null query result does not negate the potential for such an attack vector. Given these limitations, continued dark web and stealer-log monitoring is advised. Proactive credential hygiene checks, including password rotation and multi-factor authentication review, are also recommended. Monitoring of Microsoft 365, VPNs, and other remote-access portals should be maintained.
