Stealth Mango and the Prevalence of Mobile Surveillanceware presented at blackhatUSA2018 2018

by Andrew Blaich, Michael Flossman,

Summary : In this talk, we will unveil the new in-house capabilities of a nation state actor who has been observed deploying both Android and iOS surveillance tooling, known as Stealth Mango and Tangelo. The actor behind these offensive capabilities has successfully compromised the devices of government officials and military personnel in numerous countries with some directly impacting Western interests. Our research indicates this capability has been created by freelance developers who primarily release commodity spouse-ware but moonlight by selling their own custom surveillanceware to state actors. One such state actor has been observed deploying Stealth Mango and this presentation will unveil the depth and breadth of their campaigns, detailing not only how we watched them grow and develop, test, QA, and deploy their offensive tooling, but also how operation security mistakes ultimately led to their attribution.
