Researchers at Kaspersky Lab released a detailed analysis of two modules belonging to the Regin malware platform. One module is for lateral movement, the other establishes a backdoor in order to move data off compromised machines. The researchers concede that the modules, named Hopscotch and Legspin, have likely been put out of commission by those responsible for Regin and replaced by new modules. Regin has been detected on Windows computers belonging to 27 organizations in 14 countries, most of those in Asia and the Middle East.
