小白初学AFL(American Fuzzy Lop)
小白初学AFL(American Fuzzy Lop)_读书笔记-CSDN博客有幸从一位师哥那里知道这个软件,但是由于实习刚刚结束,终于有时间一探当前最为强大而有效的漏洞挖掘技术。首先我的电脑系统是WINDOWS10,而AFL支持的是Linux系统,当然大家如果不想安装双系统或者是虚拟机,可以下载WINAFL:下载地址我正好想更熟悉Linux系统就下了个虚拟机,开始了我的探索旅程。安装AFL在指定目录下检查LLVM和CLANG是否安装:sudo apt-get i...https://blog.csdn.net/weixin_39448417/article/details/99703723
在执行sudo make install的失败
提醒错误如上。
ommand 'afl' not found的错误。最后发现afl -fuzz多了个空格去掉后执行成功。
在执行afl-fuzz -i testcase -o output ./afl_test又出错了。
又去借鉴文章
AFL从入门到放弃_47大宝贝的博客-CSDN博客AFL-Fuzz工具学习AFL-Fuzz 模糊测试工具学习AFL初探安装AFL以及相关工具AFL安装llvm+clang安装开始第一次AFL-FuzzAFL-Fuzz 模糊测试工具学习AFL初探afl-fuzz全称American Fuzzy Loop,是一款特别强大的Fuzzing工具。Fuzzing是指模糊测试,Fuzzing起源很早,其思想是通过自动化产生大量的无目的输入来对目标系统进行测试。afl也是根据这一基本原理,再结合几位大佬的巧妙的构思而产生。其具体的原理、fork策略、变异策略有空的https://blog.csdn.net/weixin_41013492/article/details/107712623
afl-fuzz -i in -o out ./test的指令也发生了同样的错误。
est@ubuntu:~/AFL/AFLTest$ sudo afl-fuzz -i in -o out ./test
afl-fuzz 2.52b by <lcamtuf@google.com>
[+] You have 4 CPU cores and 3 runnable tasks (utilization: 75%).
[+] Try parallel jobs - see /usr/local/share/doc/afl/parallel_fuzzing.txt.
[*] Checking CPU core loadout...
[+] Found a free CPU core, binding to #0.
[*] Checking core_pattern...
[-] Hmm, your system is configured to send core dump notifications to an
external utility. This will cause issues: there will be an extended delay
between stumbling upon a crash and having this information relayed to the
fuzzer via the standard waitpid() API.
To avoid having crashes misinterpreted as timeouts, please log in as root
and temporarily modify /proc/sys/kernel/core_pattern, like so:
echo core >/proc/sys/kernel/core_pattern
[-] PROGRAM ABORT : Pipe at the beginning of 'core_pattern'
Location : check_crash_handling(), afl-fuzz.c:7275
test@ubuntu:~/AFL/AFLTest$
对于该问题在下面文章帮助下完成了。

AFL-FUZZ使用笔记(1)_我不是哈哈镜的博客-CSDN博客_afl-fuzz一,AFL简介AFL(American Fuzzy Lop)是一款基于覆盖引导(Coverage-guided)的模糊测试工具,它通过记录输入样本的代码覆盖率,从而调整输入样本以提高覆盖率,增加发现漏洞的概率。①从源码编译程序时进行插桩,以记录代码覆盖率(Code Coverage);②选择一些输入文件,作为初始测试集加入输入队列(queue);③将队列中的文件按一定的策略进行“突变”;④如果经过变异文件更新了覆盖范围,则将其保留添加到队列中;⑤上述过程会一直循环进行,期间触发了crash的https://blog.csdn.net/qq_42896005/article/details/108886195可以更加深入的了解
