Backdoors allow hackers to download any program they choose, including those that steal personal information, to turn the PCs into spam relay
points, or create foot soldiers to carry out other Internet attacks.
These not only allow the competitors to compete in such events as the Spam Toss, the Spam Cram and the Spam Relay
, but also provide the justification for me putting this in my column.
It can spread via network shares and email, usually requiring an absentminded user to actually open an attachment, and installs malicious backdoor and spam relay
software on the infected machine.
