Is It Still Possible to Do Phone Phreaking? Yes, With Android On LTE
But South Korean researchers say they've found several weaknesses in VoLTE networks in the U.S. and South Korea [itworld.com].
Their findings, released in a research paper, conclude that it would be possible to spoof phone calls, conduct denial-of-service attacks and overbill customers. They also found it would be possible for a malicious Android app to make secret phone calls in the background due to a flaw in the mobile OS.
The fault also lies in part with operators, which haven't full vetted their infrastructure for security issues. Also, LTE standards have been implemented in different ways by operators, opening up a variety security holes.
"Basically, there are mistakes and things they have overlooked," said Yongdae Kim, a professor with the Korea Advanced Institute of Science and Technology's (KAIST) electrical engineering department, in a phone interview Tuesday.
