A threat actor using Iranian-language tools, Iranian hosting companies, operating from the Iranian IP space at times was observed targeting the Syrian opposition in an elaborately staged malware operation, Citizen Lab researchers reveal. The operation was first noticed in late 2015, when a member of the Syrian opposition flagged a suspicious email containing a PowerPoint slideshow, which led researchers to a watering hole website with malicious programs, malicious PowerPoint files, and Android malware. The threat actor was targeting Windows and Android devices of well-connected individuals in the Syrian opposition, researchers discovered.
