Peiter ‘Mudge’ Zatko, who was Twitter’s head of security from November 2020 until he was fired in January this year, claimed the site may even have foreign spies on its payroll.
He blamed the company’s “weak cybersecurity controls and poor judgement” for leaving it vulnerable to foreign exploitation.
Mr Zatko accused the CEO Parag Agrawal of putting Twitter users and employees at risk for financial gain.
Among Mr Zatko’s claims are that Twitter has accepted money from suspicious Chinese sources and has acquiesced to Russia’s propaganda demands.
A company spokesperson has said Zatko’s allegations overall are “riddled with inconsistencies and inaccuracies, and lacks important context”.
These allegations are part of a 200 page document handed to Congress, the Justice Department and federal regulators that exposes Twitter’s leadership’s “covering up [of] critical company vulnerabilities and defrauding [of] the public”, reported CNN.
The Senate Intelligence Committee’s top Republican, Marco Rubio, said: “Twitter has a long track record of making really bad decisions on everything from censorship to security practices.
“That’s a huge concern given the company’s ability to influence the national discourse and global events.
“We’re treating the complaint with the seriousness it deserves and look forward to learning more.”
It was supposedly a plan designed to increase the site’s user base in Russia, according to the disclosure.
Mr Zatko’s disclosure says: “The fact that Twitter’s current CEO even suggested Twitter become complicit with the Putin regime is cause for concern about Twitter’s effects on US national security.”
This disclosure is becoming public just two weeks after an ex-Twitter manager was convicted of spying for Saudi Arabia.
