LastPass users warned their master passwords are compromised

Many LastPass users report that their master passwords have been compromised after receiving email warnings that someone tried to use them to log into their accounts from unknown locations.


The email notifications also mention that the login attempts have been blocked because they were made from unfamiliar locations worldwide.

"Someone just used your master password to try to log in to your account from a device or location we didn't recognize," the login alerts warn.

LastPass says it's credential stuffing

LogMeIn Global PR/AR Senior Director Nikolett Bacso-Albaum told BleepingComputer that "LastPass investigated recent reports of blocked login attempts and determined the activity is related to fairly common bot-related activity, in which a malicious or bad actor attempts to access user accounts (in this case, LastPass) using email addresses and passwords obtained from third-party breaches related to other unaffiliated services."

"It’s important to note that we do not have any indication that accounts were successfully accessed or that the LastPass service was otherwise compromised by an unauthorized party. We regularly monitor for this type of activity and will continue to take steps designed to ensure that LastPass, its users, and their data remain protected and secure," Bacso-Albaum added.

However, users receiving these warnings have stated that their passwords are unique to LastPass and not used elsewhere. BleepingComputer has asked LastPass about these concerns but has not received a reply as of yet.

While LastPass didn't share any details regarding how the threat actors behind these credential stuffing attempts, security researchers Bob Diachenko said he recently found thousands of LastPass credentials while going through Redline Stealer malware logs.

BleepingComputer was also told by LastPass customers who received such login alerts that their emails were not in the list of login pairs harvested by RedLine Stealer found by Diachenko.
