Memory performance attack
WebThese types of attacks are referred to as integrity attacks because the values in memory are not the same as what the VM intended. While an attacker cannot easily put known data into a VM’s memory without knowledge of the encryption key, they may be able to corrupt memory so that the VM sees random values or conduct replay attacks. Web14 okt. 2024 · A Jiao Tong University researcher has exploited side-channel attack techniques to crack the encryption codes protecting 3G and 4G cards. “ [The cards use] AES-128, which is supposed to be virtually unbeatable by a brute-force attack, but turns out to be easy to defeat using side-channel analysis,” explained Iain Thomson of The Register.
