The 4G wireless telecommunications protocol is vulnerable to the same types of remote exploitation as its 3G predecessor, new research emphasizes.

As with the flaw-ridden protocol underlying 3G, the 4G protocol is susceptible to attacks that disclose mobile users’ information or impose a denial of service, according to a report from mobile-security company Positive Technologies.

Security researchers have long warned that spies or hackers could exploit the protocol supporting 3G — known as Signaling System No. 7 (SS7) — to intercept or track call data. The move from 3G to 4G, and the latter’s Diameter protocol, was supposed to mitigate some vulnerabilities, but security experts also have made clear that Diameter is no safeguard against hacking.
