American manufacturing firm Mercury Corp. announced the leak of confidential information for more than 3,000 people after a cyberattack that occurred in February 2025. The attackers were on the system for only 24 hours, but that was enough to gain access to driver’s licenses, social security numbers, and other personal data.
Although the company stated in the letter that the investigation could not establish with certainty the scale of the breach or the fact of data export, the very fact of gaining access to such sensitive PII (personally identifiable information) already poses a serious threat to victims. Cybercriminals can use this information to commit fraud: open credit accounts, file false tax returns, or conduct phishing campaigns that will be extremely convincing due to the presence of real personal data.
Mercury Corp. (formerly Mercury Aircraft) is a company with a nearly century-old history that began as a supplier of aircraft parts for the US military. Today, its partners include giants such as IBM, Lockheed Martin, USPS, and Kodak. Despite its long-standing presence in the market and cooperation with government and defense contractors, the company has found itself vulnerable to modern cyber threats.
Incident with Mercury Corp. once again demonstrates that even experienced players in the market, with a long reputation, can become victims of quick and targeted attacks. One day of an attacker’s stay in the system and thousands of people are left at risk of identity theft. Such cases should serve as an incentive for manufacturing companies to strengthen security policies, especially when it comes to the data of employees, customers and government partners.
