Android Device is Vulnerable to a Hardware called RAMpage

DELHI, India - July 4, 2018 - PRLog -- RAMpage is a hardware threat which hampers the devices by many ways like Rowhammer, Shattered Trust, Cloak and Dagger and other various other attack. Rampage enables to get root access on a device.

It might be used to bypass JavaScript sandboxes and performs an attack on virtual machines. The android device which embeds ARM processor is also vulnerable to the Smartphone. DRAMMER(Deterministic Row hammer Attacks) is a new attack on mobile devices that exploits the Row hammer hardware vulnerability on android devices.

RAMpage is vulnerable for the unified memory management interface for Android ion. ION was primarily announced with android 4.0 at 2011 and enables to gives application the memory they need to execute. But this hardware able to access all memory on the devices from within any applications.

It become hard to safeguard against DRAMMER as it's a hardware threat , protecting Android ion will reduce most of the damage which can be done. The researchers calls it GuardION and have announced it as open source.

This susceptible hardware attacks on the memory of the devices by exploiting all the matter from the particular devices. When CPU reads a row of bits in the RAM module available on the devices, the hardware affects the proximity rows by tiny electric discharge.

It is an ordinary problem but what if we start hammering the same row by again and again read or writes the particular row to distort proximity rows? The Rowhammer acquires this ability and its being used as a part of a greater vulnerability, known as RAMpage. It causes a bit- flip in a rows of memory which is not accessible at all for users.

Rowhammer is a vulnerable in DRAM(dynamic random access memory) chips that enables an attacker to draw out DRAM memory by continuously accessing (known as hammering) a row of memory. It causes a bit flip in a memory of rows and transistors in proximity rows of memory reverse their binary state.
