# AFL ###### tags: `pentest log` ## Amercan Fuzzy Lop I've tried two afl-* compiler, one is `afl-gcc` and the other is `afl-clang-fast`, to know what's different on the speed. The reason is that when I use afl-gcc on my laptop, it turn out to be some cpu scaling issue required by afl. Meanwhile, I tried it on my Desktop, nothing happened. ### Result - Laptop, Kali ![](https://i.imgur.com/7Go85I7.png) However, by running `afl-fuzz`, I felt no different comparing these two. Curiously I search some relative material about it, which shown below. It said that the total path is less while compile with afl-clang-fast. ![](https://i.imgur.com/Vheb0ZB.png) ### Result - Desktop, Ubuntu ![](https://i.imgur.com/83nbpIy.png) ![](https://i.imgur.com/wxFIR1A.png) ![](https://i.imgur.com/tiDO0aL.png) ### Crashes Analysis I was trying to use `exploitable plugin` in gdb, and crashwalk( automated crash analysis)... But facing an issue that I cannot use it even though I've intalled it. ![](https://i.imgur.com/LdaKTKQ.png) Therefore, I wish there will be more time introduce it deeply and widely.
