DESCRIPTION
Trojans-
PSWs
Trojans stealing
passwords
Trojans stealing passwords (Password
Stealing Ware); they steal users'
accounts, for example, software
registration information. They find
confidential information in the system files
and in the registry and send it to their
developer by e-mail, via FTP, accessing
the intruder's website or using other
methods.
Some of these Trojan programs fall into
specific types described in this table.
These are Trojan programs stealing
banking account information
(Trojans-Bankers), Trojan programs
stealing personal data of the users of IM
client programs (Trojans-IMs) and Trojan
programs stealing data from the users of
network games (Trojans-GameThieves).
Trojans-
Spies
Trojan spy
programs
These programs are used for spying after
the user: they collect information about
the user's actions on the computer, for
example, they intercept data entered by
the user from the keyboard, make
snapshots of the screen and collect lists of
active applications. After they receive this
information, they transfer it to the intruder
by e-mail, via FTP, by accessing the
intruder's website or using other methods.
Trojans-
DDoS
Trojan programs -
network attacks
They send numerous requests from the
user's computer to the remote server. The
server will then exhaust its resources for
processing requests and will stop
functioning (Denial-of-Service (DoS)).
These programs are often used to infect
multiple computers in order to attack the
server from them.
