AI-summarised brief · reviewed before publication

A former IBM cybersecurity executive, William Barlow, has accused the company of covering up several data breaches by foreign governments between 2013 and 2019. Barlow, who was IBM's vice president of threat intelligence until August 2019, filed a lawsuit in 2020 alleging that IBM's core network was breached at least three times, with data stolen and government agencies never notified. The alleged breaches also affected IBM subsidiaries and partners, including AT&T.
