It’s been almost a month since the OPM breach, and there’s been much speculation and leaks pointing to the details of the attack. Here is a recap of released information so far:
June 4, 2015 - OPM announces they’ve been breached.
June 8, 2015 - Guidance Software announces that EnCase® was used in OPM’s investigation. I am quoted by SC Magazine, hinting that the PlugX Remote Access Trojan (RAT) was utilized by OPM’s attackers.
