WASHINGTON (AP) — Catching a cheating lover online using commercial spyware seems to be easier than nabbing the hacker behind it.

The FBI this week added to its list of most wanted cybercriminals a former San Diego college student who developed an $89 program called “Loverspy” or “Email PI.” Sold online from his apartment, the program would send the suspected cheater an electronic greeting card that, if opened, would install malicious software that could capture emails and instant messages, even spy on someone using the victim’s own webcam.
