For the very first time, security researchers have discovered an effective way to exploit a four-year-old hacking technique called Rowhammer to hijack an Android phone remotely.
Dubbed GLitch, the proof-of-concept technique is a new addition to the Rowhammer attack series which leverages embedded graphics processing units (GPUs) to carry out a Rowhammer attack against Android smartphones.
Rowhammer is a problem with recent generation dynamic random access memory (DRAM) chips in which repeatedly accessing a row of memory can cause “bit flipping” in an adjacent row, allowing anyone to change the value of contents stored in computer memory.
