Hotspot sniffer eavesdrops on iPhone in real-time
“As the private call is in progress, we can see and hear what is happening,” said Jason Ostrom, a developer of UCSniff and director of Viper Labs, the research arm of security firm Sipera Systems. “There’s real-time violation of confidentiality.”
In addition to monitoring voice conversations as they happen, UCSniff can also bug video conferences in real time. Ostrom said he and fellow Viper Labs researcher Arjun Sambamoorthy plan to show those capabilities at Toorcon as well.
With the proliferation of iPhones and other smartphones, plenty of businesses and individuals have sought to save money on roaming charges by routing calls over the internet instead of over carrier networks. Adam Boone, a vice president at Sipera, said one large, unnamed client logs more than 1 million minutes per month in such VoIP calls.
The problem, he added, is that many of the iPhone apps for VoIP calls don’t provide encryption capabilities, making the conversations ripe for eavesdropping. (Sipera plans to unveil a new product to protect such users next week).
