Commercial spamflooding used by crooks to tie up their victims at key moments

Security expert Brian Krebs was the target of a malicious email flood, and writes firsthand about the experience. These floods -- which can be directed at any and all of your phone (voice or SMS) and email -- are used by crooks who want to busy-out all their victims' communications channels while they are ripping them off electronically. This kind of flooding is available as a (surprisingly cheap) commercial service.

Used mostly in private for myself and now offered to the respected public.

  1. krebs walks into a seedy bar, and the bartender says “what’ll ya have?” krebs orders a full bottle of mezcal tequila, opens it, and pours the contents on the floor. the dumbfounded barkeep has to know why he did it, and krebs replies “just here to remove a worm.”

  2. Hmmm…doesn’t Marcus do something like this to another classmate early in Little Brother creating a diversion so he and his friends sneak out of class?

  3. This sounds very Shadowrun.  Tie up the corporate network to cause a distraction while your team sneaks in to kidnap/rescue/recruit a talented employee who’s been working on a brilliant unauthorized side project.   Plus orks.
