Pieter Zatko joins Twitter

Social media giant Twitter has appointed Peiter Zatko, one of the world’s best-regarded hackers to tackle everything from engineering missteps to misinformation.

The company on Monday night named Zatko, widely known by his hacker handle Mudge, to the new position of head of security.

He has a broad mandate to recommend changes in structure and practices.

Zatko answers to CEO Jack Dorsey and is expected to take over management of key security functions after a 45- to 60-day review.

In an interview, Zatko said he will examine “information security, site integrity, physical security, platform integrity — which starts to touch on abuse and manipulation of the platform — and engineering.”

Zatko most recently oversaw security at the electronic payments unicorn Stripe.

Before that, he worked on special projects at Google and oversaw handing out grants for projects on cybersecurity at the Pentagon’s famed Defense Advanced Research and Projects Agency (DARPA).

Zatko’s colourful career began in the 1990s, when he simultaneously conducted classified work for a government contractor and was among the leaders of Cult of the Dead Cow, a hacking group notorious for releasing Windows hacking tools in order to goad Microsoft into improving security. reut.rs/2IxWD3Q

Twitter faces numerous security challenges.

A year ago, the U.S. government accused two men of spying for Saudi Arabia when they worked at Twitter years earlier, saying that they passed along private information about the kingdom’s critics. here
