Visser Precision, a parts maker and manufacturing solutions provider for the aerospace, automotive, industrial and manufacturing industries, has reportedly suffered a combination ransomware attack and data breach that has compromised files pertaining to multiple business partners, including Tesla, SpaceX, Boeing and Lockheed Martin.

In a statement, Denver, Colorado-based Visser confirmed it was “the recent target of a criminal cybersecurity incident, including access to or theft of data,” according to a report from TechCrunch, which was tipped off by the security company Emsisoft. The culprit in this instance was reportedly DoppelPaymer, a ransomware program that not only encrypts files but also steals assets so extortionists can dox them publicly if the ransom is not paid.

Reportedly, the cybercriminals behind the attack have already began publishing its Visser’s clients’ stolen files and documents and making certain ones available for download. These include non-disclosure agreements between Visser and the Elon Musk-founded Tesla and SpaceX, and what seems to be a partial schematic for a Lockheed Martin-manufactured missile antenna.

TechCrunch reported that Boeing, Tesla and SpaceX have not responded to requests for comment. However, a Lockheed Martin spokesperson, however reportedly said the company is “aware of the situation with Visser Precision and are following our standard response process for potential cyber incidents related to our supply chain.”
