Here is an interesting attack method: launch a denial-of-phone attack to prevent communication with a bank while draining the accounts. Apparently, fake VoIP accounts were setup to phone the victim repeatedly while the bad guys transferred thousands of dollars out of the accounts. This is an example of a cross-over attack using different types of technologies to perform the fraud.
The FBI says the calls were a diversionary tactic, meant to tie up Thousand’s line so that Ameritrade couldn’t reach him to authenticate the money transfer requests.
