Monster Worldwide, the owner of employment search site,
began notifying this week the estimated 1.3 million users affected by a
breach that leaked résumé information and pledged to beef up network
monitoring and defenses to prevent such a leak from happening again.

As reported by SecurityFocus,
a malicious Trojan-horse program dubbed Infostealer.Monstres accessed
résumé data using stolen, but valid, employer credentials and copied
the information to a remote server. The information included names,
physical and e-mail addresses, and phone numbers. At least one reader
of SecurityFocus has claimed to have been notified by Monster that their information had been stolen.
