I'm preparing for my Wednesday talk about the security market, and just found this BBC report, with some analysis of the recent biannual Symantec Threat Report which identified Voice over IP (Voip) systems as a technology starting to interest hi-tech criminals.
The report predicted that within 18 months, Voip will start to be used as a "significant" attack vector. As well as prompting new attacks, Voip could also resurrect some old hacking techniques, warned the report.
The growing use of Voip could encourage the emergence of:
- audio spam that clogs voicemail boxes with spoken adverts
- voice phishing that tries to con people into handing over confidential details
- caller-ID spoofing which allows conmen to make it look like they are calling from a legitimate number such as a victim's bank
- call hi-jacking that re-directs calls to conmen and criminals
