Editing Keystroke logging (section)

=== Trojans ===
Researchers Adam Young and Moti Yung discussed several methods of sending keystroke logging. They presented a deniable password snatching attack in which the keystroke logging trojan is installed using a virus or [[Computer worm|worm]]. An attacker who is caught with the virus or worm can claim to be a victim. The [[cryptotrojan]] asymmetrically encrypts the pilfered login/password pairs using the [[public key]] of the trojan author and covertly broadcasts the resulting [[ciphertext]]. They mentioned that the ciphertext can be [[steganography|steganographically]] encoded and posted to a public bulletin board such as [[Usenet]].<ref name="auto">{{cite book |last1=Young |first1=Adam |last2=Yung |first2=Moti |title=Proceedings. 1997 IEEE Symposium on Security and Privacy (Cat.
