Pija is a proof of concept about how malware can easily detect and steal homemade adult content from the victim's computer.

This PoC only contains the detection bits of the concept, but can be further improved using different techniques such as biometrics and metadata analysis to find matches between suspicious pictures and victim's social network's photos.

Ths was developed as part of a presentation we (@mattaereal & @alcuadrado) gave at Ekoparty 2013. You can watch it here (spanish) and grab the slides from here (mostly spanish).
