Hacker attack on federal security contractor not noticed for months, report claims

A cyberattack on federal security clearance contractor USIS, was unnoticed for months before it was revealed by the company and government agencies earlier this year, according to a published report.

Officials and others familiar with an FBI investigation and related official inquiries told The Associated Press that the breach, similar to previous hacker intrusions from China, compromised the private records of at least 25,000 employees at the Homeland Security Department and cost the company hundreds of millions of dollars in lost government contracts.

In addition to trying to identify the perpetrators and evaluate the scale of the stolen material, the government inquiries have prompted concerns about why computer detection alarms inside the company failed to quickly notice the hackers and whether federal agencies that hired the company should have monitored its practices more closely.
