  "textContent": "Hello everyone!\n\nMe and my friend. We are still learning, and recently we tried to make a very simple, hobby antivirus/security project written in C. We call it, F4us.\n\nIt is far from perfect and still in a very early development phase. We just wanted to learn how some basic security concepts work under the hood.\n\nWhat we tried to build:\n\n  * A simple honeypot script to log suspicious access.\n  * A basic entropy function to check file structures.\n  * A background daemon loop to monitor files.\n\n\n\nSince we are still beginners, we know there are probably a lot of bugs and messy code in it. We just wanted to share this hobby journey here. Thank you for reading!\nhere is the link(github), sorry if include many bugs or critical,it just an experiment:\nhttps://github.com/CornelI5/F4us\nmy friend was out, he are in crashout cause this project is too hard.\nbtw, dont use this in your real computer, trust me. just use VM(Virtual Machine),or you will get BSOD(blue screen of death) or kernel panic.",
