Researchers exploit cellular tech flaws to intercept phone calls

Researchers showed a Black Hat audience how femotcell technology, used by phone companies to boost cell phone coverage, can be hacked to intercept cell phone calls, text messages and other data. Tom Ritter and Doug DePerry , researchers from iSec Partners, used an femtocell from Verizon to demonstrate how hackers can eavesdrop on phone conversations and see text messages and photos sent or received by nearby cell phone users.
