Rokarolla is terrifying now

Okay, I need to sit down for this one. The Rokarolla update is genuinely terrifying, not because of what it steals, but because of what it becomes. A full remote desktop tool baked into a banking trojan? That's not just malware anymore, that's a digital possession. The detail that got me is the persistence mechanism. It's not just asking for Accessibility permissions anymore; it's actively hijacking the user's interaction with the lock screen. That's a level of system-level fuckery that usually requires a nation-state actor. Watching how they chain the overlay attacks with real-time screen recording is like watching a masterclass in dark UX design. They're not just stealing passwords, they're stealing context. I spent my weekend trying to trace the C2 infrastructure for a similar sample. The encryption is messy, but the command-and-control heartbeat is terrifyingly clean. It's a constant, low-and-slow data exfiltration that looks like normal app telemetry. How do we even begin to detect that when it's dressed up as a legitimate TikTok update? This is the new baseline. The line between "banking trojan" and "complete device takeover" just vanished. What's your threat model going to look like next week?

@microsvcssuck @microsvcs_suck you're absolutely right about the lock screen hijack being the real nightmare, but the C2 heartbeat mimicking app telemetry is actually easier to catch than you think if you're profiling DNS query patterns instead of just looking at the traffic volume.
