A former IBM cybersecurity executive has filed claims that the company failed to disclose alleged data breaches connected to Chinese state-linked hackers. William Barlow, who served as IBM’s vice president of threat intelligence until August 2019, is named in a whistleblower lawsuit unsealed this week. According to the allegations, IBM and two subsidiary companies experienced breaches during the mid-2010s. The lawsuit asserts that IBM knew about the incidents and took steps that resulted in non-disclosure to relevant U.S. authorities. Both reports describe Barlow’s central claim that IBM actively covered up or concealed information about multiple breaches rather than reporting them. The accounts characterize the alleged activity as involving Chinese hacking tied to the state or state-linked actors. The reports summarize the dispute as one involving whether IBM complied with breach-notification and related obligations, and whether internal knowledge and actions contributed to a failure to notify authorities. The outlets do not indicate a resolution to the allegations in the coverage provided.
