The e-mail appeared to be an invitation from an old, junior high school friend. Yet when the hospital employee clicked on the link, it instead led her to a malicious site that installed a Trojan horse on her computer. In a little over a week, international cybercriminals used that beachhead to steal more than $600,000 from the woman's employer, according to a terse description of the incident on the Information Systems Security Association’s Web site.
A number of similar incidents to this one highlight the threats of online crime facing small and midsize businesses (SMBs), says Stan Stahl, president of Citadel Information Group and president of the Los Angeles chapter of the ISSA.
"Typically, they say, 'We have firewalls in place and have AV on all the desktops, so I guess we are secure,'" Stahl says. "But today cybercrime is so sophisticated that is not enough anymore."
