About six months ago, I discovered something on my smartphone that horrified me: I went to undelete a file in DiskDigger, and I stumbled upon a plethora of unexpected jpegs: screenshots of my activity. Screenshots that I didn't take. Screenshots of my conversations. Screenshots of my GPS position. And screenshots of my bitcoin wallet.
I was perplexed. I was astonished. And, to be honest, I was scared. How did this happen? Was it a vulnerability shipped with LineageOS? Could it be some malicious binary embedded into AOSP? Or is it some exploit in one of those damned closed-source apps that I was forced to install through social pressure (*cough* whatsapp)?
