I never said I got root at Linode, but I did have root at Linode.
FWIW I dumped all the MIT, nmap and Sucuri data in HTP5 and popped the shells on swiftircd boxes (who IIRC ended up being the first ones to alert linode to our presence). It’s not any kind of an achievement, but hard to claim I wasn’t deeply involved.
As far as I know none of the stuff about informants in the Linode section was true. I don’t think anyone got hacked and had their handler standing behind them, at least I never heard more of that story. Ryan King and Rory Guidry continued their involvement with HTP long after the Linode stuff.
Did informants kill hacker groups? I don’t think so. FBI infiltration of hacker groups predates the death of hacker groups by well over a decade, it never stopped anyone.
