Late last week, Gyrodata, a major oil drilling specialist, conceded that it had suffered from a ransomware attack that likely led to the compromise of employee data, including former and current staff. The company is based in Houston and claims to be one of the world’s leading suppliers of technology and tools designed to extract hydrocarbons from the earth. The company stated that it discovered the security breach on February 21.

It is unclear whether the cyberattack caused any disruption to the firm or its services, however, the data leaked pertaining to employees contains information such as names, addresses, dates of birth, Social Security numbers, passport numbers, W-2 tax forms, information related to health plan enrollment, and driver’s license numbers. The firm has allegedly been contacting affected individuals by post. Gyrodata boasts roughly 1000 employees worldwide.
