The Rowhammer glitch takes place in a densely-populated cell hardware environment allowing an attacker to modify memory cells without directly accessing it.

Rowhammer attack takes advantage of this Hardware vulnerability. For the intrinsic properties of DRAMs, this leads to a decreases in the charge of single cells and could cause electromagnetic coupling effects between cells. In this report, we will focus on the Rowhammer and Microarchitectural attacks that will be discussed in the following paragraphs.Īs miniaturization of hardware architectures is pushed more and more, the density of memory cells of the DRAM drives the size of these cells to a dramatic reduction in dimensions. A comprehensive list of examples for every type of attacks is given, along with a constructive discussion on possible countermeasures. The authors distinguish among Local, Vicinity and Remote Side Channel Attacks, depending on how close is the attacker to the attacked device. Also the distance of an attacker is a relevant element in the analysis of Side-channel attacks. The concept of Software and Hardware attacks are identified to separate attacks that exploit, respectively, logical and physical properties of a device. Side-channel attacks are initially categorized as active or passive, depending on the level of influence and involvement the attack has on the system.

Side-channel attacks aims to extract sensitive information taking advantage of apparently harmless information leakage of computing devices, both from the SW and HW point of view. The analyzed paper deals with Side-Channel attacks on mobile devices, providing a thorough categorization based on several factors.
