Key Takeaways From the Twitter Whistleblower’s Testimony

Former Twitter safety chief Peiter Zatko, aka “Mudge,” testified earlier than a Senate panel (video) Tuesday alleging widespread safety deficiencies on the social media firm. His testimony expanded on the 200+ web page whistleblower grievance submitted to Congress final month.

Zatko, who was Twitter’s head of safety from November 2020 till being fired in January 2022, alleged “excessive, egregious deficiencies” in areas of consumer privateness, digital and bodily safety, and platform integrity/content material moderation.

“What I found after I joined Twitter was that this enormously influential firm was over a decade behind trade safety requirements,” he stated in his testimony.

No Framework to Shield Consumer Information

As a social media platform, Twitter is sitting on a large trove of consumer data, such because the consumer’s telephone quantity, the consumer’s present and previous IP addresses used to connect with Twitter, present and previous e mail addresses, the individual’s approximate location primarily based on IP addresses, the consumer’s language, and details about the individual’s machine or browser they’re utilizing.

Defending that data is important. That data, within the mistaken arms, can be utilized to dox particular person customers and open them as much as bodily hurt. The communications can expose data customers might not need publicized.

Twitter would not know “what they’ve, the place it lives, or the place it got here from,” Zatko instructed Congressional lawmakers throughout his testimony. “And so, unsurprisingly, they cannot defend it.”

No Entry Logs

One of many core tenets of information safety is to have entry controls so that there’s a method to monitor if anybody is accessing data they shouldn’t be. Twitter didn’t have that sort of logging, Zatko stated, claiming that Twitter had no visibility over what anybody was doing with the info.

Workers have “an excessive amount of entry to an excessive amount of knowledge,” Zatko stated. The knowledge is out there to roughly half of Twitter’s employees, or about 4,000 workers, and engineers are given entry to the info by default, he stated.

The shortage of controls made account takeovers trivial. “It is not far-fetched to say an worker inside the corporate might take over the accounts of all of the senators on this room,” Zatko stated. “It would not matter who has keys if you haven’t any locks on the doorways.”

That state of affairs is not so far-fetched. Zatko got here to Twitter shortly after a 2020 incident the place a bunch of youngsters gained entry to an inner software after which took over the accounts of high-profile Twitter customers as a part of a crypto-currency rip-off.

“From analysis that I coordinated after the 2020 incident, it was apparent that Twitter didn’t have acceptable privileged consumer administration controls nor separation of obligation insurance policies for builders and directors of their programs,” Aaron Turner, CTO of SaaS Shield at Vectra, beforehand instructed Darkish Studying.

Pink Flags Have been Ignored

One system that tracked logins for Twitter engineers was registering “1000’s” of failed login makes an attempt every week, Zatko stated. Even if the corporate noticed as many as 3,000 failed makes an attempt every day, the corporate didn’t prioritize investigating to see the place the makes an attempt had been coming from, or what programs had been being focused.

Not investigating was a missed alternative. Making an attempt to determine what the failed makes an attempt had been focusing on might have helped establish probably susceptible programs, and whether or not they wanted extra layers of safety.

Twitter is “to date behind on their infrastructure,” and the engineers aren’t given the chance to modernize the platform, Zatko testified.

Twitter has pushed again on the allegations. A spokesperson stated, “At the moment’s listening to solely confirms that Mr. Zatko’s allegations are riddled with inconsistencies and inaccuracies.”
