Accusations fly over voice encryption hack

Vendor accuses rival of being behind ‘tests’.

German encryption firm SecurStar has strenuously denied being behind an apparently independent test of voice encryption products that found many of its rivals could be hacked using a $100 phone-tapping program.

In a blog on the subject, Fabio Pietrosanti, founder and CTO of Swiss encryption startup Khamsa, alleges that a supposedly independent test of 15 encryption products was in fact a marketing exercise designed to publicise one of only three products to pass the hacking test, SecurStar’s PhoneCrypt.

The tests by an anonymous researcher, ‘Notrax’, found that all but three programs and hardware products looked at could be bypassed by installing a simple wiretapping Trojan called FlexiSPY to record voice output without the programs giving the user any indication that security had been compromised.
