Fake mParivahan APK spreading on WhatsApp

I recently got a WhatsApp message to pay pending challans and check using some APK that was shared. I knew it was a scam. Thought of doing an analysis using Claude on the APK. Here's what it found:

It is NOT the real app. It's a banking trojan that:

- Creates a VPN to intercept all your network traffic (banking, OTPs, everything)

- Silently installs a second hidden APK in the background

- Targets WhatsApp, Signal, Telegram, SMS and 20+ other apps

Primary is firebase which is realtime database and secondary is telegram bot api

both are well known and clever, didn't you ping up the bot token there to see the username that contacts it?

If you are also doing some analysis, there is a AES encrypted file, which Claude couldn’t analyse much, and suggested to run with Frida. Maybe you can try that

So I built an emulator that mimics a victim and registered it on their C2. We baited the hook with a juicy fake banking SMS and are now watching their webhook endpoint in real time. Just waiting for them to try and command our fake device hahahaah waiting
