Ex-Twitter exec blows the whistle, alleging reckless and negligent cybersecurity policies

Twitter has major security problems that pose a threat to its own users' personal information, to company shareholders, to national security, and to democracy, according to an explosive whistleblower disclosure obtained exclusively by CNN and The Washington Post.

The disclosure, sent last month to Congress and federal agencies, paints a picture of a chaotic and reckless environment at a mismanaged company that allows too many of its staff access to the platform's central controls and most sensitive information without adequate oversight. It also alleges that some of the company's senior-most executives have been trying to cover up Twitter's serious vulnerabilities, and that one or more current employees may be working for a foreign intelligence service.
