Whistleblower Accuses Twitter of Cybersecurity Negligence

A former head of security at Twitter alleged that the company misled regulators about its cybersecurity defenses, privacy protections and its ability to detect and root out fake accounts, according to a whistleblower complaint filed with US officials.

The revelation could create serious legal and financial problems for the social media platform, which is currently attempting to force Tesla CEO Elon Musk to consummate his $44 billion offer to buy the company.

Peiter Zatko, Twitter's security chief until he was fired early this year, filed complaints last month with the US Securities and Exchange Commission, the Federal Trade Commission and the Department of Justice. The legal nonprofit Whistleblower Aid, which is working with Zatko, confirmed the authenticity of a redacted copy of the complaint posted online by the Washington Post.

Among Zatko's most serious accusations is that Twitter violated the terms of a 2011 FTC settlement by falsely claiming that it had strong security measures in place to protect the security and privacy of its users. Zatko also accuses the company of deceptions involving its handling of “spam" or fake accounts, an allegation that is at the core of Musk's attempt to back out of the Twitter takeover.

Shares of Twitter Inc. slid 5.4% Tuesday. Zatko didn't immediately respond to a request for comment Tuesday. But he told the Post he “felt ethically bound” to come forward.

Better known by his hacker handle “Mudge,” Zatko is a highly respected cybersecurity expert who first gained prominence in the 1990s and later worked in senior positions at the Pentagon’s Defense Advanced Research Agency and Google.

He joined Twitter at the urging of then-CEO Jack Dorsey in late 2020, the same year the company suffered an embarrassing security breach involving hackers who broke into the Twitter accounts of world leaders, celebrities and tech moguls, including Musk, in an attempt to scam their followers out of bitcoin.

Twitter said in a prepared statement Tuesday that Zatko was fired for “ineffective leadership and poor performance” and said the “allegations and opportunistic timing appear designed to capture attention and inflict harm on Twitter, its customers and its shareholders.” The company called his complaint “a false narrative” that is “riddled with inconsistencies and inaccuracies and lacks important context.”

Zatko's attorneys, Debra Katz and Alexis Ronickher, said Twitter's claim about his poor performance is false and that he repeatedly raised concerns about “grossly inadequate information security systems” with top executives and Twitter's board of directors. The lawyers said that in late 2021, after the board was given “whitewashed” information about those security problems, Zatko escalated his concerns, “clashed” with CEO Parag Agrawal and board member Omid Kordestani and was fired two weeks later.

The 84-page complaint describes a broken corporate culture at Twitter that lacked effective leadership and where Zatko said top executives practiced “deliberate ignorance” of pressing problems. His description of Dorsey’s leadership style is particularly scathing, saying the Twitter founder was “extremely disengaged” during the last months of his tenure as CEO to the point where he would not even speak during meetings on complex issues facing the company.

Zatko said he heard from colleagues that Dorsey would remain silent for “days or weeks.” Dorsey announced he was stepping down as Twitter CEO in November 2021.

The disclosure says Twitter offered no monetary incentives for improving security and platform integrity, although the company did offer $10 million bonuses last year for top executives who could generate short-term user growth.

Among Zatko’s damning accusations of cybersecurity malpractice: Software and security updates were disabled on more than a third of employees’ computers -- unduly exposing them to malware -- and it was common for people to install “whatever software they wanted on their work systems.” Such lapses are typically considered cardinal sins in cybersecurity.

Whistleblower Aid said it is legally precluded from sharing Zatko's statement. The same group worked with former Facebook employee Frances Haugen, who testified to Congress last year after leaking internal documents and accusing the social media giant of choosing profit over safety.

A spokesperson for the US Senate's intelligence committee, Rachel Cohen, said the committee has received Zatko's complaint and "is in the process of setting up a meeting to discuss the allegations in further detail. We take this matter seriously.”

Sen. Dick Durbin, an Illinois Democrat, said in a prepared statement that if the claims are accurate, “they may show dangerous data privacy and security risks for Twitter users around the world.”

Among the most alarming complaints is Zatko’s allegation that Twitter knowingly allowed the Indian government to place its agents on the company payroll where they had “direct unsupervised access to the company’s systems and user data.”

A 2011 FTC complaint noted that Twitter’s systems were full of highly sensitive data that could allow a hostile government to find precise location data for specific users and target them for violence or arrest.

Zatko also describes “deliberate ignorance” by Twitter executives on counting the millions of accounts that are automated “spam bots" or otherwise have no value to advertisers because there is no person behind them.

Alex Spiro, an attorney representing Musk in his effort to back out of his Twitter acquisition deal, said lawyers have issued a subpoena for Zatko. “We found his exit and that of other key employees curious in light of what we have been finding,” Spiro wrote in an email Tuesday. Spiro said Zatko and Musk have not been in contact at any time this year.

Founder of TikTok Owner ByteDance Jumps to Top of China’s Rich List

ByteDance founder Zhang Yiming is China's richest person, with personal wealth of $49.3 billion, an annual rich list showed on Tuesday, although counterparts in real estate and renewables have fared less well.

Zhang, 41, who stepped down as chief executive of ByteDance in 2021, becomes the 18th individual to be crowned China's richest person in the 26 years since the Hurun China Rich List was first published.

He overtook bottled water magnate Zhong Shanshan, who slipped to second place as his fortune dropped 24% to $47.9 billion.

Despite a legal battle over its US assets, ByteDance's global revenue grew 30% last year to $110 billion, Hurun said, helping to propel Zhang's personal fortune.

Third on the list was Tencent's low-profile founder, Pony Ma, while Colin Huang, founder of PDD Holdings, slipped to fourth place from third last year, even as his firm's discount-focused e-commerce platforms, Pinduoduo and Temu, continue to show healthy revenue growth.

The number of billionaires on the list dropped by 142 to 753, shrinking more than a third from its 2021 peak.

"China’s economy and stock markets had a difficult year," said Hurun Report Chairman Rupert Hoogewerf.

The most dramatic falls in fortunes have come from China's real estate sector, he added, while consumer electronics is clearly rising fast, with Xiaomi founder Lei Jun adding $5 billion to his wealth this year.

"Solar panel, lithium battery and EV makers have had a challenging year, as competition intensified, leading to a glut, and the threat of tariffs added to uncertainties," said Hoogewerf, who is also the list's chief researcher.

"Solar panel makers saw their wealth down as much as 80% from the 2021 peak, while battery and EV makers were down by half and a quarter respectively."
