Menguak Isi Email

13Apr09

Email sangat sering kita gunakan, apalagi zaman Blackberry seperti sekarang. Tapi tahukah Anda, informasi yang terkandung pada sebuah email sangat kompleks?

Tim investigasi mencoba mengirim email ke diri sendiri, yang hanya terdiri atas satu baris dan dua buah attachment file kecil, dan berikut inilah hasilnya.

Sebuah email terdiri atas bagian header dan body. Header email mendeskripsikan metadata (RS ™) mengenai sebuah email.
