Web3 mrt. 2024 · Historically, there’s been a substantial impact on CPU performance when scanning memory, limiting its ability to be used broadly for attack detection. To meet the threat of fileless attacks in a performant way, CrowdStrike partnered with Intel Corporation to integrate its Intel TDT AMS into our Falcon sensor. 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.
