BlackRock is derived from the leaked source code of the Xerxes banking malware, a known strain of LokiBot Android trojan. Unlike other banking trojans, it targets a lot of non-financial Android apps, with a focus on social, communication, networking, and dating platforms. BlackRock’s credential theft target list includes Microsoft Outlook, Gmail, Uber, Amazon, Netflix, Cash App, and banks like Santander, Barclays, RBS, Lloyds, ING, and Wells Fargo.
