Even the LastPass Will be Stolen, Deal with It!

I am back from Amsterdam after presenting our research at Blackhat “Even the LastPass Will be Stolen, Deal with It!” together with Alberto Garcia. We had a blast at the conference and we got great feedback from the audience. Many asked for the video, slides, etc. so I though it was worth writing a post with all the details of our talk.

Motivation

During one of Alberto’s red team pentests, he gained access to several machines and found that all of them had files with references to LastPass. He came to me and told me it would be cool to check how LastPass works and if it was possible to steal LastPass credentials. 10% of our time is for research so we made that our small project.

We found how creds where stored locally and wrote a Metasploit plugin so he could use it to extract vault contents from all the compromised machines. Thanks to the module, he was able to obtain SSH keys to critical servers and the pentest was a success.
