Former Twitter executive Peiter "Mudge" Zatko said the social media giant has major security problems and accused the company of cybersecurity negligence, which could pose a threat to the personal information of its users, company shareholders and national security, reporting by CNN and The Washington Post has revealed.

Zatko, who was previously the company's head of security of Twitter, was fired from his role in January 2022 over “poor performance and ineffective leadership”.

In his disclosure, Zatko claimed that Twitter had hired two people whom he believes to be foreign government agents. The two had “direct unsupervised access” to internal Twitter data and information, the disclosure revealed.

Predictably, Twitter CEO Parag Agrawal, in an internal email, dismissed Zatko's claims as a "false narrative" that is "frustrating and confusing to read".

Zatko sent the disclosure to the US Congress and federal agencies last month.

In response to the claims, a Twitter spokesperson told CNN that the company has had security and privacy as long-time priorities. The statement said that there were “inconsistencies and inaccuracies, and lacks important context" in the accusations levelled by Zatko.

"Mr. Zatko's allegations and opportunistic timing appear designed to capture attention and inflict harm on Twitter, its customers and its shareholders," the statement added.

Congress leader and Lok Sabha MP Manish Tewari shared the news on Twitter, highlighting Zatko's claims about two Indian government agents.

Christopher Bouzy, founder of Bot Sentinel — a platform against disinformation and targeted harassment online — said he has no doubt that Zatko is being truthful.

The whistleblower alleges that the company is “Lying about Bots to Elon Musk.”
