Durandal is not known for any hacks or accomplishments. The only thing he is known for is his time in SOLDIERX and for being the only member that was ever exiled by SOLDIERX. He was brought into SOLDIERX by BadGer, the former Vice President of SOLDIERX. According to BadGer, Durandal was an annoying kid who would not leave him alone until he let him become a member. This went unknown for almost 10 years (when BadGer came forward after hearing of Durandal's expulsion from the group).
Through snitching and hustling, Durandal lied his way into the rank of Vice President of SOLDIERX. After promising to give a speech at Defcon 16 and then failing to work on it or even show up, Durandal was stripped of his rank in SOLDIERX. Several weeks later, recordings surfaced of a conversation where he attempted to dime out other members of SOLDIERX. Upon this revelation, Amp posted the recordings and announced his immediate expulsion from the group. Afterwards, other accounts were submitted and verified - including his involvement as a narc against both David Condrey (Conundrum) and Anthony Jerdine. On another note, it turns out that the person who social engineered him over the phone was Kevin Mitnick (or at least claimed to be).
