This Black Hat Europe session frames mobile malware as a state surveillance channel for Russian, Chinese, and North Korean threat actors. The source does not provide the full technical slide detail, but it states that the presenters compare targeting choices and operating methods across those regions and introduce previously unreported malware families. For Lazarus Day use, the DPRK relevance is the session's North Korea case-study coverage of mobile surveillance tradecraft rather than a single incident or IOC set.
