In this short video I will show you, how you can build a backdoor in OpenSSH 5.9
1. Define the backdoor password in auth.h 2. Edit the auth-passwd.c file and set the backdoor into it 3. Set integer ‘backdoorActive’ in log.h 4. Disable logging for the backdoor login in log.c 5. Compile 6. Test the backdoor :-)
