The reported problem is with the Skype software. SIP is a protocol. There's
no useful comparison to be made.

Aware that Skype is a proprietary system whilst SIP is an open
protocol.

Reported in above story that Skype has a habit of port hopping to dodge
firewalls presumably to make user setup easy, along with large userbase
makes it attractive to hackers.

As anything takes off it will become target of attacks, happens with
browsers all the time, Firefox has had quite a few security
vunerabilities patched recently.

Seem to remember a variant of PGP being introduced to allow secure,
scrambled, voice communication.

Just wondering if there are yet any reported attempted attacks on SIP
based systems be it `tapping` or exploitation of SIP clients to run
malicious code?

Thanks
Adam

Some resources related to VoIP security may be found at

http://www.voipsa.org/

There you will find a recent publication, the Threat Taxonomy document,
which identifies and discusses what that organisation perceives the
threats to VOIP security to be.

Also of interest is
