Wait, how secure is IRC anyway? The article states that he trusted Sabu, but didn't he also trust the people who ran the IRC servers plus anybody able to sniff their traffic?
He connected to IRC via Tor overlay. I don’t know what IRC network is Anonymous using, but even Freenode offers native Onion gateway to their network[1].
Ok, scratch "anybody able to sniff their traffic" (assuming both sides use the native gateway.) This still leaves the IRC server itself as a potential vulnerability.
