But South Korean researchers say they've found several weaknesses in VoLTE networks in the U.S. and South Korea.
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[y] 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.
T-Mobile, Verizon and AT&T were notified of the issues in May, according to an advisory updated on Monday from Carnegie Mellon University's CERT. None of the companies had an immediate comment.

What the hell does this have to do with this story?
The story isn't even about flaws in Andorid, but rather weaknesses in VOLTE. You can exploit them with any SIP client.
No, you are mistaken. I've always had this sig.
