Hackers are using Snowden leaks to reverse-engineer NSA techniques

Over the past year, we’ve learned of the many techniques the NSA has used to tap into global communications. However, Edward Snowden’s document leaks didn’t just uncover the gadgets the agency used, they also gave security researchers the necessary insights to develop their own. After the NSA’s classified Advanced Network Technology catalogue was published, Michael Ossmann and his team set about recreating two of its approved radio-based surveillance devices: one that could be fixed to a computer’s monitor connector to send on-screen images and another that can be fixed to a keyboard cable to collect keystrokes.
