Security hacks is one of the major concern with most mobile phones - be it high end devices or low-end phone. Now, a report has revealed the security vulnerability in Samsung's high-end handsets, namely Galaxy S6, Note 5 and S6 Edge which are powered by Exynos 7420 chipset which fall under "Shannon" line of baseband LTE modems.
According to a report, Security researchers have found a way to snoop on phone calls made through a Samsung smartphone through a malicious base station. The flaw has been found by Daniel Komaromy and Nico Golde who have classified this as "man in the middle attack" on phones that carry Samsung's modems.
The researchers set up a mobile base station close to the target phone and released a malicious firmware to the phone's baseband processor, which is a chipset that handles voice calls. The reroutes phone then automatically connects through this malicious base station due to vulnerability in Samsung's chipset. Such a way, calls can be recorded automatically each time a user talk to someone through these phones. All of this can be done without letting the user ever know about the process.
The researchers have not given out full details of this attack but they have disclosed that it affects Samsung's high end devices. Hopefully, this security flaw will be fixed in the near future.
