SIM Cards in 29 Countries Vulnerable to Remote Simjacker Attacks

SIM Cards in 29 Countries Vulnerable to Remote Simjacker Attacks

October 12, 2019Swati Khandelwal
Until now, I'm sure you all might have heard of the SimJacker vulnerability disclosed exactly a month ago that affects a wide range of SIM cards and can remotely be exploited to hack into any mobile phone just by sending a specially crafted binary SMS. If you are unaware, the name "SimJacker" has been given to a class of vulnerabilities that resides due to a lack of authentication and proprietary security mechanisms implemented by dynamic SIM toolkits that come embedded in modern SIM cards. Out of many, two such widely used SIM toolkits — S@T Browser technology and Wireless Internet Browser (WIB) — have yet been found vulnerable to SimJacker attacks, details of which we have provided in our previous articles published last month. At that time, a few experts in the telecom industry confirmed The Hacker News that the SimJacker related weaknesses were internally known to many for years, and even researchers also revealed that an unnamed surveillance company has been
Google Tracks Android, iPhone Users Even With 'Location History' Turned Off

Google Tracks Android, iPhone Users Even With 'Location History' Turned Off

Google tracks you everywhere, even if you explicitly tell it not to. Every time a service like Google Maps wants to use your location, Google asks your permission to allow access to your location if you want to use it for navigating, but a new investigation shows that the company does track you anyway. An investigation by Associated Press revealed that many Google services on Android and iPhone devices store records of your location data even when you have paused "Location History" on your mobile devices. Disabling " Location History " in the privacy settings of Google applications should prevent Google from keeping track of your every movement, as its own support page states: "You can turn off Location History at any time. With Location History off, the places you go are no longer stored." However, AP found that even with Location History turned off, some Google apps automatically store "time-stamped location data" on users without ask
Security flaw in 3G could allow anyone to track your smartphone

Security flaw in 3G could allow anyone to track your smartphone

New privacy threats have been uncovered by security researchers that could allow every device operating on 3G networks to be tracked, according to research from the University of Birmingham with collaboration from the Technical University of Berlin. Researchers said that standard off-the-shelf equipment, such as femtocells, could be used to exploit the flaw, allowing the physical location of devices to be revealed. The 3G standard was designed to protect a user's identity when on a given network. A device's permanent identity, known as International Mobile Subscriber Identity (IMSI) is protected on a network by being assigned a temporary identity called a Temporary Mobile Subscriber Identity TMSI. The TMSI is updated regularly while the 3G networks are supposed to make it impossible for someone to track a device even if they are eavesdropping on the radio link. Researchers have discovered that these methods can easily be sidestepped by spoofing an IMSI paging reques
