| Description | (Trend Micro) ChewBacca is a PoS RAM scraper family, first discovered at the end of 2013, which uses the Tor network to exfiltrate stolen data. When first executed, ChewBacca copies itself to %USERPROFILE%\START MENU\Programs\Startup\spoolsv.exe and adds itself to an Auto Start runkey to remain persistent. It is self-contained and installs obfsproxy v0.2.3.25—a Tor proxy application—in %TEMP%. It then hooks WH_KEYBOARD_LL, which monitors keyboard input events. This allows ChewBacca to capture all keyboard events, which are then logged to %TEMP%\system.log. | |
