Unlike desktops, your mobile devices carry all sorts of information from your personal emails to your sensitive financial details. And due to this, the hackers have shifted their interest to the mobile platform.
Every week new exploits are discovered for iOS and Android platform, most of the times separately, but the recently discovered exploit targets both Android as well as iOS devices.
A team of security researchers from Tel Aviv University, Technion and The University of Adelaide has devised an attack to steal cryptographic keys used to protect Bitcoin wallets, Apple Pay accounts, and other highly sensitive services from Android and iOS devices.
The team is the same group of researchers who had experimented a number of different hacks to extract data from computers. Last month, the team demonstrated how to steal sensitive data from a target air-gapped computer located in another room.
Past years, the team also demonstrated how to extract secret decryption keys from computers using just a radio receiver and a piece of pita bread, and how to extract the cryptographic key just by solely touching the chassis of the computer.
According to the researchers, the recent exploit is a non-invasive Side-Channel Attack: Attack that extracts the secret crypto key from a system by analyzing the pattern of memory utilization or the electromagnetic outputs of the device that are emitted during the decryption process.
The exploit works against the Elliptic Curve Digital Signature Algorithm (ECDSA), a standard digital signature algorithm that is most widely used in many applications like Bitcoin wallets and Apple Pay and is faster than several other cryptosystems.

Good choice putting $4,000 rims on your 1990 Honda Civic. That's like Betty White going out and getting her tits done.
