Through the Looking Glass: Webcam Interception and Protection in Kernel
VIRUS BULLETIN www.virusbulletin.com Covering the global threat landscape THROUGH THE LOOKING GLASS: and WIA (Windows Image Acquisition), which provides a WEBCAM INTERCEPTION AND still image acquisition API. PROTECTION IN KERNEL MODE ATTACK VECTORS Ronen Slavin & Michael Maltsev Reason Software, USA Let’s pretend for a moment that we’re the bad guys. We have gained control of a victim’s computer and we can run any code on it. We would like to use his camera to get a photo or a video to use for our nefarious purposes. What are our INTRODUCTION options? When we talk about digital privacy, the computer’s webcam The simplest option is just to use one of the user-mode APIs is one of the most relevant components. We all have a tiny mentioned previously. By default, Windows allows every fear that someone might be looking through our computer’s app to access the computer’s camera, with the exception of camera, spying on us and watching our every move [1]. And Store apps on Windows 10. The downside for the attackers is while some of us think this scenario is restricted to the realm that camera access will turn on the indicator LED, giving the of movies, the reality is that malware authors and threat victim an indication that somebody is watching him. actors don’t shy away from incorporating such capabilities A sneakier method is to spy on the victim when he turns on into their malware arsenals [2]. the camera himself. Patrick Wardle described a technique Camera manufacturers protect their customers by incorporating like this for Mac [8], but there’s no reason the principle into their devices an indicator LED that illuminates when can’t be applied to Windows, albeit with a slightly different the camera is in use. -
