Monster Worldwide, the owner of employment search site Monster.com, 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.
