Security watchers have identified a new batch of malicious e-greeting spam that conceals keylogging spyware designed to steal online banking passwords and other sensitive information.
Targeting South American PC users, the spam campaign poses a "dangerous financial risk," according to SurfControl.
In June 2005, the security firm predicted that there would be an increase and spread of malicious e-greeting spam and now, a year later, the threat appears to be showing no sign of abating.
With the Easter holidays just round the corner, the firm said it anticipates a flurry of malicious e-greetings as malcode writers and spammers seek to exploit the religious festivities.
"A user's inquisitive nature can often be the weakest link in a company's fight against malware, as employees are known to open the email and follow the links, believing the spam to have originated from friends or family members," said Susan Larson, vice president of SurfControl's Adaptive Threat Intelligence service.
