The FDIC and security experts have responded to the House Committee on Science, Space and Technology's scathing investigation report about hackers breaching the banking agency's computers repeatedly between 2010 and 2013.

The report claimed cyberattackers, purportedly from China, placed backdoor malware on a dozen workstations and 10 servers, including those of the chairman, chief of staff and the FDIC's general counsel. The House committee investigation concluded the agency misled auditors about the extent of those breaches and told employees not to talk about the breaches.

In April, the FDIC detected and moved to mitigate a breach of 44,000 customer records after an employee leaving the agency in February inadvertently downloaded the data containing personally identifiable information to a removable media device. Within three days of the breach, an agency data loss prevention tool detected the download. The employee returned the device with the data the next day, according to the original FDIC account.
