Stamos confirmed in a March 19 tweet that he is leavng and that his role at the company has changed, but he said he is still fully engaged in his new tasks focusing on emerging risks and election security on the site. Facebook has promised an investigation and Cambridge has denied any wrongdoing.
Facebook Chief Security Officer Alex Stamos gives a keynote address during the Black Hat information security conference in Las Vegas, Nevada, U.S. July 26, 2017. In a tweet, Stamos said his role changed, but "I'm now spending more time exploring emerging security risks and working on election security".
Stamos released a statement addressing the reports Monday night. "I'm now spending more time exploring emerging security risks and working on election security", Stamos wrote. "He has held this position for almost three years and leads our security efforts especially around emerging security risks". His decision to leave Yahoo in 2014 was at least partly to do with disagreements he had with CEO Marissa Mayer over the company's security standards, which he felt were not strict enough.
The Times report also follows Facebook's announcement last week that it had suspended Cambridge Analytica over evidence that it used data from 50 million user profiles to craft messages on the social network designed at influencing elections.
This isn't the first time Stamos has left a C-suite position at a major tech company in the midst of controversy.
Facebook has a very tight, and long-tenured executive team, and while Stamos was not necessarily in CEO Mark Zuckerberg's most immediate circle, he had a significant role at a very significant moment for the company. The tweets said the situation, in which the firm accessed information from millions of Facebook accounts, wasn't a data breach or a leak. "Nobody is not aware of the risks".
