Electronic greeting card spam has been the most recent way criminals try to infect people's computers with botnet software.

With enough bots in place, researchers at McAfee believe a massive DDoS attack driven by the botnet could happen on a mammoth scale.
Researcher Rachit Mathur wrote on McAfee's Avert Blog that variants of this Storm worm employ server-based polymorphism to evade detection.
"The code for the top-level decryptor of the executable hosted on the server keeps changing while still preserving the overall semantics," said Mathur.
The worm has been tucked into thousands of spams bearing fake greeting card executables. By using various polymorphism techniques, the worm can evade detection by security software.
Criminals backing the botnet will likely use it for financial gain, continuing a trend of fortune-seeking through malicious technology. A botnet can churn out millions of spams, or be used to extort money from a website with a DDoS threat.
