How do they work on linux? According to Wikipedia, file-less malware is a variant of computer related malicious software that exists exclusively as a computer memory-based artifact i.e. in RAM. In other words, the malware/program is never written to harddisk but directly loaded in memory. To get a better understanding of how that happens in linux, we need to understand how a normal program loads itself into memory and executes itself. https://ayedaemon.github.io/post/2021/02/keylogger-for-linux/ Tue, 02 Feb 2021 14:47:26 +0530 https://ayedaemon.github.io/post/2021/02/keylogger-for-linux/ <blockquote> <p>Developing a low level keylogger for linux using C.</p> </blockquote> https://ayedaemon.github.io/post/2020/12/advanced-intrusion-detection-environment/ Sat, 19 Dec 2020 14:25:28 +0530 https://ayedaemon.github.io/post/2020/12/advanced-intrusion-detection-environment/ <blockquote> <p>Host-based intrusion detection system (HIDS) for checking the integrity of files.</p> </blockquote> https://ayedaemon.github.io/post/2020/12/luks-disk-encryption/ Sat, 19 Dec 2020 13:15:55 +0530 https://ayedaemon.github.io/post/2020/12/luks-disk-encryption/ <blockquote> <p>Linux Unified Key Encryption — Disk Encryption</p> </blockquote>
