U.S. Central Intelligence Agency team specializes in reusing bits of code and techniques from public malware samples. Leaked documents show the Umbrage team is part of the Remote Development Branch under the CIA’s Center for Cyber Intelligence. It maintains a library of techniques borrowed from in-the-wild malware that could be integrated into its own projects. One of the techniques borrowed was the file wiping implementation in Shamoon, a cybersabotage program used to destroy data from 30,000 computers at Saudi Arabia’s national oil company in 2012.”]
