Submission + - Spoken commands crash bank phone lines (scmagazine.com.au) 1

mask.of.sanity writes: A series of attacks have been made that are capable of disabling touch tone and voice activated phone systems or forcing them to disclose sensitive information.

The commands can be keyed in using touchtones or even using the human voice.

In one test, a phone system run by an unnamed Indian bank had dumped customer PINs. In another, a buffer overflow was triggered against a back-end database. Other attacks can be used to crash phone systems outright.
