If the attachment is opened, it sends similar emails to addresses found on the computer and downloads code intended to add the PC to a botnet used for sending spam. Symantec's analysis shows that the latest versions of the malware include a rootkit capable of hiding several files and registry keys, although it fails to conceal the ports it uses and has other bugs that can cause crashes.
An infected machine has been observed sending nearly 1800 stock-pumping messages in five minutes before falling quiet. Symantec reports that this Trojan accounts for over a quarter of all the spam being sent around the world in the last month. The company gives it a 3 on its 5-point severity scale as although the potential for damage is high, it is easily contained.
