A possible cyber attack on the GSEs was one of the focuses of a semi-annual report to Congress by the Federal Housing Finance Agency’s Office of Inspector General. The computer systems of Fannie and Freddie could be vulnerable to security breaches and unauthorized access, according to the report, which noted that the IG specifically worries about hackers possibly stealing confidential information and/or planting computer viruses within the systems of the GSEs. “Among other things, a breach of an enterprise’s security system could disrupt its business operations or result in the unauthorized disclosure or misuse, computer viruses or other malicious codes, or other attempts to harm them or misuse or steal confidential information,” said the report.
