LastPass Says Home Computer of DevOps Engineer Was Hacked

wiredmikey shares a report from SecurityWeek: Password management software firm LastPass says one of its DevOps engineers had a personal home computer hacked and implanted with keylogging malware as part of a sustained cyberattack that exfiltrated corporate data from the cloud storage resources. LastPass on Monday fessed up a 'second attack' where an unnamed threat actor combined data stolen from an August breach with information available from a third-party data breach, and a vulnerability in a third-party media software package to launch a coordinated attack.

LastPass worked with incident response experts at Mandiant to perform forensics and found that a DevOps engineer's home computer was targeted to get around security mitigations. The attackers exploited a remote code execution vulnerability in a third-party media software package and planted keylogger malware on the employee's personal computer. 'The threat actor was able to capture the employee's master password as it was entered, after the employee authenticated with MFA, and gain access to the DevOps engineer's LastPass corporate vault,' the company said. 'The threat actor then exported the native corporate vault entries and content of shared folders, which contained encrypted secure notes with access and decryption keys needed to access the AWS S3 LastPass production backups, other cloud-based storage resources, and some related critical database backups,' LastPass confirmed. LastPass originally disclosed the breach in August 2022 and warned that 'some source code and technical information were stolen.'

SecurityWeek adds: 'In January 2023, the company said the breach was far worse than originally reported and included the theft of account usernames, salted and hashed passwords, a portion of Multi-Factor Authentication (MFA) settings, as well as some product settings and licensing information.'
