Facebook admits it stored ‘hundreds of millions’ of account passwords in plaintext

Flip the “days since last Facebook">Facebook Security incident” back to zero.

Facebook confirmed Thursday in a blog post, prompted by Security.com/2019/03/Facebook-stored-hundreds-of-millions-of-user-passwords-in-plain-text-for-years/">a report by cyberSecurity reporter Brian Krebs, that it stored “hundreds of millions” of account passwords in plaintext for years.

The discovery was made in January, said Facebook’s Pedro Canahuati, as part of a routine Security review. None of the passwords were visible to anyone outside Facebook, he said. Facebook admitted the Security lapse months later, after Krebs said logs were accessible to some 2,000 engineers and developers.

“This caught our attention because our login systems are designed to mask passwords using techniques that make them unreadable,” said Canahuati. “We have found no evidence to date that anyone internally abused or improperly accessed them.”

Facebook said it will notify “hundreds of millions of Facebook Lite users,” and “tens of millions of other Facebook users.” The company also said “tens of thousands of Instagram users” will be notified of the exposure.

It’s the latest in a string of embarrassing Security issues at the company, prompting Facebook-cicilline-antitrust-house-congress/">congressional inquiries and Facebooks-cambridge-analytica-disclosures/">government investigations.
