A program used by U.S. and British spies to record computer keystrokes was part of sophisticated hacking operations in more than a dozen countries, security experts said on Tuesday, after former NSA contractor Edward Snowden reportedly leaked the source code for the program.
On Tuesday, researchers at security software firm Kaspersky Lab said that much of that code, published this month by German magazine Spiegel, matched what they previously found in machines infected by Regin, a major suite of spying tools exposed in November.
Lead Kaspersky researcher Costin Raiu said that the key -logging program, called Qwerty, would work only with Regin, and that it appeared several Western countries' spies had been using Regin over the course of a decade.
