Malicious hackers are turning their attention to the technology behind net phone calls, says a report.

The biannual Symantec Threat Report 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.
