Twitter whistleblower testifies of serious security flaws to Senate

Twitter’s former security chief Peiter “Mudge” Zatko testified to a Senate panel on Tuesday that his former employer prioritized income over addressing security considerations that he mentioned put person data in danger of falling into the flawed palms.

“It’s not far-fetched to say that an employee inside the company could take over the accounts of all of the senators in this room,” Zatko advised members of the Senate Judiciary Committee, lower than a month after his whistleblower criticism was publicly reported.

Zatko testified that Twitter lacked fundamental security measures and had a freewheeling method to knowledge entry amongst staff, opening the platform to main dangers. As he wrote in his criticism, Zatko mentioned he believed an agent of the Indian authorities managed to turn into an worker on the firm, an instance of the implications of lax security practices.

The testimony provides gasoline to the criticism by legislators that main tech platforms put income and development targets over person safety. While many firms have flaws of their security methods, Twitter’s distinctive place as a de facto public sq. has amplified Zatko’s revelations, which took on additional significance given Twitter’s authorized spat with Elon Musk.

Musk sought to purchase the corporate for $44 billion however then tried to again out of the deal, claiming Twitter ought to have been extra forthcoming with details about the way it calculates its share of spam accounts. A decide within the case lately mentioned Musk might revise his counterclaims to reference points Zatko raised.

A Twitter spokesperson disputed Zatko’s testimony and mentioned the corporate makes use of entry controls, background checks and monitoring and detection methods to management entry to knowledge.

“Today’s hearing only confirms that Mr. Zatko’s allegations are riddled with inconsistencies and inaccuracies,” the spokesperson mentioned in an announcement, including that the corporate’s hiring is impartial from overseas affect.

Here are the important thing takeaways from Zatko’s testimony

Lack of management over knowledge

According to Zatko, Twitter’s methods are so disorganized that the platform cannot say for positive if it is deleted a customers’ knowledge solely. That’s as a result of Twitter hasn’t tracked the place all that knowledge is saved.

“They don’t know what data they have, where it lives or where it came from, and so, unsurprisingly, they can’t protect it,” Zatko mentioned.

Karim Hijazi, CEO of cyber intelligence agency Prevailion, mentioned giant organizations like Twitter typically expertise “infrastructure drift,” when folks come and go, and completely different methods are typically uncared for.

“It tends to be a little bit like someone’s garage over time,” mentioned Hijazi, who beforehand served as director of intelligence at Mandiant, now owned by Google. “Now the problem is, unlike a garage where you can go in and you can start pulling it all apart sort of methodically … you can’t simply wipe away the database because it’s a patchwork quilt of new information and old information.”

Taking down some elements with out figuring out for positive whether or not they’re important items might danger bringing down the broader system, Hijazi mentioned.

But security specialists expressed shock by Zatko’s testimony that Twitter did not also have a staging surroundings to check updates, an intermediate step engineers can take between the event and manufacturing environments to work out points with their code earlier than setting it reside.

“That was quite surprising for a big tech firm like Twitter to not have the basics,” Hijazi mentioned. Even the smallest little startups on this planet which have began seven and a half weeks in the past have a dev, staging and manufacturing environments.”

Chris Lehman, CEO of SafeGuard Cyber and a former FireEye vice president, said “that will be surprising to me” if it’s true Twitter doesn’t have a staging environment.

He said “most mature organizations” would have this step to prevent systems from breaking on the live website.

“Without a staging surroundings, you create extra alternatives for bugs and for issues,” Lehman said.

Broad employee access to user information

Zatko said the lack of understanding of where data lives means employees also have far more access than they should to Twitter’s systems.

“It would not matter who has keys if you haven’t any locks on the doorways,” Zatko said.

Engineers, who make up a large portion of the company, are given access to Twitter’s live testing environment by default, Zatko claimed. He said that type of access should be restricted to a smaller group.

With so many employees having access to important information, the company is vulnerable to problematic activities like bribes and hacks, Hijazi and Lehman said.

One-time fines that often result from settlements with U.S. regulators like the Federal Trade Commission are not enough to incentivize stronger security practices, Zatko testified.

Zatko told Sen. Richard Blumenthal, D-Conn., that a $150 million settlement like the one Twitter reached with the FTC in May over allegations it misrepresented how it used contact information to target ads, would be insufficient to deter the company from bad security practices.

The company, he said, would be far more worried about European regulators that could impose more lasting remedies.

“While I used to be there, the priority solely actually was a few considerably greater quantity,” Zatko said. “Or if it will have been a extra institutional restructuring danger. But that quantity would have been of little concern whereas I used to be there.”

Despite the flaws, users shouldn’t necessarily feel compelled to delete their accounts, Zatko and other security experts said.

“People can at all times choose to simply disconnect,” Lehman said. “But the fact is, social media platforms are platforms for dialogue. And they’re the brand new city sq.. That serves a public good. I feel it will be dangerous if folks simply stopped utilizing it.”

Hijazi said there’s no point in going into hiding.

“That’s not possible this present day,” he said. “However, I feel that being naive to the idea that these organizations actually have this beneath management and really have your data secured is defective.”
