PSW Trojans (Password-stealing Trojans)

These Trojans are designed to steal passwords from the victim’s computer (although some steal other types of information also:

IP address, registration details, e-mail client details, and so on).

This information is then sent to an e-mail address coded into the body of the Trojan.

The first PSW Trojans emerged in the 1990s and were AOL password stealing Trojans.
