在AndroidManifest.xml文件中添加所需的权限。我们需要添加android.permission.SET_TRACE和android.permission.PTRACE_ATTACH权限,以便开启ptrace。 <manifestxmlns:android="package="com.example.myapplication"><!-- 添加ptrace相关权限 --><uses-permissionandroid:name="android.permission.SET_TRACE"/><uses-permission...
我建议 jann horn 将这个变量名改成 ptracelinkcreater_cred, 当 trace link 由 PTRACE_ATTACH 建立时, 它等于 tracer 的 cred, 当 trace link 由 PTRACE_TRACEME 建立时, 它等于 tracee 的 cred, 它实际上记录的是 trace 关系建立者的权限 ! exploit 本漏洞利用的关键是找到合适的可执行程序启动 task B, ...
When a ptrace(PTRACE_ATTACH, ..) is called with the pid to be traced, it is roughly equivalent to the process calling ptrace(PTRACE_TRACEME, ..) and becoming a child of the tracing process. The traced process is sent a SIGSTOP, so we can examine and modify the process as usual. Af...
init(); let target_pid: pid_t = 7777; let traced_process = TracedProcess::attach(RawProcess::new(target_pid))?; // OwnedProcess / Die on detach // // let process = OwnedProcess::from( // std::process::Command::new(executable_path) // .spawn() // .expect("spawn")); // /...
Theptrace(2)interface entails interpreting a series ofwait(2)statuses. The context used to interpret a status includes the attach options set on each tracee, previously-seen stops, recent ptrace requests, and in some cases, extra event data that must be queried using additional ptrace calls. ...

Now, we can attach to dummy2 by using the code below: #include <sys/ptrace.h> #include <sys/types.h> #include <sys/wait.h> #include <unistd.h> #include <linux/user.h> /* For user_regs_struct etc. */ int main(int argc, char *argv[]) { pid_t traced_process; struct user_...
There are a few things to note about this example. First, although it is not documented anywhere, you must first PTRACE_ATTACH to the target process before you can open the /proc memory image file. This is a security feature. Also, unless you're attaching to yourself (/proc/self/mem),...
