There have been tons of spam runs I have seen from "hijacked" blocks were simply announcing an unused block or a de-agg of a used block, sending spam for a few minutes / hours / days, and stopping the announcement.
This does not require special techniques, just an upstream willing to accept & propagate your announcement. Alex & Anthony's preso is about intercepting legit traffic, not sending illegitimate traffic.
