How did the crooks get in given that the needed access credentials of 4 developers at LastPass were locked up in a secure password vault to which only four developers had access?”
Access to the vault password was accomplished by targeting the DevOps engineer’s home computer and exploiting a vulnerable third-party media software package, which enabled remote code execution capability and allowed the threat actor to implant keylogger malware. 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.
Why there was apparently no requirement for 2FA for opening up the corporate vault, in addition to the 2FA used when the employee first authenticated? Why was the 3rd party software not updated?
