The identity thieves who ransacked Monster.com's database also made off with the personal information of 146,000 people who use USAJobs, the federal government's official job search site, federal officials said today.

Monster Worldwide Inc. operates the USAJobs.gov Web site for the Office of Personnel Management (OPM), the independent agency that manages the federal civil service. Like Monster's commercial sites, USAJobs lets job seekers post resumes and federal agencies post job openings.

Of the 2 million subscribers to the federal job site, about 146,000 were affected by the heist engineered by Infostealer.Monstres, a Trojan horse that used legitimate log-on credentials stolen from recruiters to sift through the Monster database. According to Monster executives, the Trojan absconded with the names, addresses, e-mail addresses and phone numbers of some 1.3 million people. Although stored in the Monster databases, some of those people were USAJobs users. No Social Security numbers were stolen, the OPM stressed in an alert posted to USAJobs.
