If you use LastPass, make sure to change your master password. Just in case.
According to a newly released statement by LastPass, there is ‘no indication’ of any data breach following users' reports that they had been notified of unauthorized logins. The popular password manager company claims that it has never been hacked and that no user accounts have been accessed by malicious actors.
The scare about a potential data breach originally came to light on December 27 when a LastPass user submitted a post to Hacker News, stating that they received a security alert from LassPass about a blocked login attempt from Brazil. According to the user, the person who attempted the login was using their LastPass account's master password.
As panic among LastPass users began to spread across social media, the company launched an investigation into the possible incident.
LastPass points to credential stuffing attacks
“Our initial findings led us to believe that these alerts were triggered due to LastPass’s ongoing efforts to defend its customers from bad actors and credential stuffing attempts. It is also important to remember that LastPass’ zero-knowledge security model means that at no time does LastPass store, have knowledge of, or have access to a user’s Master Password(s),” Gabor Angyal, VP of Engineering at LastPass, said in the company’s blog post.
If these findings are correct, the security warnings might have been sent as a result of threat actors trying to gain access to multiple LastPass accounts using stolen login credentials acquired from unrelated data breaches.
According to Angyal, the investigation has shown “no indication that any LastPass accounts were compromised,” and the company found no evidence that any login credentials were stolen by “malware, rogue browser extensions, or phishing campaigns.”
“Our investigation has since found that some of these security alerts, which were sent to a limited subset of LastPass users, were likely triggered in error. As a result, we have adjusted our security alert systems and this issue has since been resolved,” reads the LastPass statement.
If you’re a LastPass user, this might be a good time to change your master password.
Even though the company’s own investigation found ‘no indication’ of compromise, we highly recommend you create a new master password immediately and enable two-factor authentication if possible.
