Twitter "don't know what data they have, where it lives, or where it came from and so, unsurprisingly, they can't protect it." That was just one of the claims made by the company's former security lead, Peiter "Mudge" Zatko in testimony to the US Senate's Judiciary Committee. Zatko alleged Twitter had made false statements about its security, defrauded investors and had been either negligent or complicit in the face of foreign influence operations. He added that, a week before he was fired, the FBI had told him there was at least one Chinese intelligence agent on Twitter's payroll.
Zatko's testimony would be comic if it weren't so serious. As he explains, he joined the company to lead its security operations after an infamous hack in which "a group of teenagers launched what at the time was the largest hack of a social media platform in history." When he arrived he found "10 years of overdue critical security issues" with no meaningful progress in addressing them. "This was a ticking bomb of security vulnerabilities," he added. He said he repeatedly disclosed his concerns which went "unheeded." When he told an executive that there was a foreign spy inside the organisation, he said he was told, "Well, since we already have one, what does it matter if we have more? Let's keep growing the office.”
Not all social media platforms are like Twitter but we continue to be deeply concerned about entrusting them with sensitive information. Last week, two senior Facebook engineers admitted that they didn't know where all the data about a user is stored and thought there was no single person who would know. Their admission came during a court hearing as part of a lawsuit over the mishandling of private user information during the Cambridge Analytica affair. Facebook's parent company argues that it continues to make significant investments to meet its privacy commitments. We don't doubt that's true but it's not the same as ensuring privacy is protected.
