The FBI may or may not have portable, password-stealing devices, the agency said in response to a Freedom of Information Act request.

“The mere acknowledgment of whether or not the FBI has any such records in and of itself would disclose techniques, procedures and/or guidelines that could reasonably be expected to risk of circumvention of the law,” the agency said in response to a records submitted by Motherboard. “Thus, the FBI neither confirms nor denies the existence of any records.”
