Compressed VoIP Calls Vulnerable To Bugging
holy_calamity writes "Security researchers at Johns Hopkins report that a variable bit-rate compression scheme being rolled out on VoIP systems leaves encrypted calls vulnerable to bugging. Simpler syllables are squeezed into smaller data packets, with more complex ones taking up more space; the researchers built software that uses this to spot phrases of interest in encrypted calls simply by measuring packet size."http://slashdot.org/slashdot-it.pl?f.../06/13/1449232
