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. -
Xilinx XAPP545 Statistical Profiler for Embedded IBM Powerpc, Application Note
Product Not Recommended for New Designs Application Note: Virtex-II Pro R Statistical Profiler for Embedded IBM PowerPC XAPP545 (v1.0) September 15, 2004 Author: Njuguna Njoroge Summary This application note describes how to generate statistical profiling information from the IBM PowerPC 405D, which is embedded in some Virtex-II Pro™ FPGAs. Specifically, the application note details how to convert trace output files generated from the Agilent Technologies Trace Port Analyzer into a gprof (GNU profiler) readable format. The gprof tool is capable of generating a histogram of a program's functions and a call-graph table of those functions. Introduction Profiling allows a programmer to assess where a program is spending most of its time and how frequently functions are being called. With this information, a programmer can gain insight as to what optimizations to make. In some cases, a programmer can identify bugs that would be otherwise undetectable. Using the RISCWatch application is a first step in profiling a program. Nonetheless, manually mulling through approximately 350 MB (or 8 million cycles) of trace data to discern the run-time profile of the program is a fruitless endeavor. In fact, the designers of RISCWatch realized this, so they standardized the trace output format to enable post processing of the trace. The regular format of the trace files allows scripts to parse through the trace and convert it to the gprof format. By converting the trace files into the gprof format, the widespread use of gprof in the profiling community -

Flare-On 5: Challenge 7 Solution – Worldofwarcraft.Exe
Flare-On 5: Challenge 7 Solution – WorldOfWarcraft.exe Challenge Author: Ryan Warns Summary This challenge implements a 32-bit Windows binary meant to run in a Windows on Windows (WOW) environment. Analysis I often start my analysis of samples by quickly skimming the output of static analysis tools and looking through IDA. Performing basic static analysis on the binary we see that WorldOfWarcraft.exe is a simple 32-bit DLL. Running strings.exe on this binary shows us several strings that look like they might be related to the key. USER32 WS2_32 %[email protected] Cannot read payload! n1ght_4lve$_R_c00L.bin A_l1ttl3_P1C_0f_h3aV3n RSDS R:\objchk_win7_x86\i386\WorldOfWarcraft.pdb Figure 1 - strings in WorldOfWarcraft.exe Opening the binary in IDA we can see that the binary doesn’t appear to implement much in the way of functionality, with the main function only calling 3 subroutines. The subroutine at address 0x1001A60 contains references to our strings of interest. FireEye, Inc., 1440 McCarthy Blvd., Milpitas, CA 95035 | +1 408.321.6300 | +1 877.FIREEYE (347.3393) | [email protected] | www.FireEye.com 1 Figure 2 - Decompilation of function using interesting strings I’ve cleaned up the decompilation in the screenshot above to be slightly more accurate. Quickly skimming sub_1001910 reveals that this function grabs the contents of a file, so it looks like sub_0x1001A60 will read the file n1ght_4lve$_R_c00L.bin and XOR the contents against the string A_l1ttl3_P1C_0f_h3aV3n. The result of this operation is compared to a static array on the stack, and if the two match the sample will print our key. -
