A few weeks ago, Wikileaks released another slew of hacking tools from the CIA.  This batch outlined an interesting tool codenamed ExpressLane that was used to determine if agencies that were sharing biometric data with the CIA was withholding information from the CIA.  The Hacker News has a breakdown of the process and how it was used, but it is a fascinating looking into how distrustful the CIA is with “partner” agencies (both in and outside of the US).  It also highlights why physical security still plays a key role in protecting information assets.
