Contractor Unisys Corp. allegedly failed to detect cyber break-ins traced to a Chinese-language Web site. DHS was not aware for at least three months of cyber-intrusions that began in June 2006.

The contractor also allegedly falsely certified that the network had been protected to cover up lax oversight.”]
