FCW.com News - Lawmakers to DHS: Investigate response to cyberattacks

Unisys provided inaccurate and misleading information to DHS about the source of the attacks and attempted to hide security gaps, the lawmakers said in their letter. Furthermore, DHS officials did not act on the information once they were informed.

“When presented with the reality that hackers were within their systems, department officials preferred to complete the fiscal year’s financial transactions rather than immediately take steps to mitigate the problem,” the lawmakers wrote. That decision could have further compromised critical DHS' financial information.
