Trojan.Redgamble – How Does It Infect
The main method via which this virus may be spread onto victims computers is by being attached in spammed email messages, whose main purpose is to get users to believe the infection file is an important type of document, such as:
- Invoice.
- Receipt.
- Banking statement.
- Waranty.
The e-mails that are sent may often seem as if they come fro big companies, like PayPal, DHL, FedEx, UPS, etc. The attached files to those e-mails may be executable types of files, like .exe, .bat, .cmd, .vbs, .sfx and others of such types. If so, these files are often in archives in order to evade detection. But if not, the files may be presented as .docx or .pdf files with malicious macros embedded. This basically means that the files themselves appear to be legitimate but when opened they ask victims to enable editing to see what is in the document and this action triggers malicious macros to activate the infeciton process.
Trojan.Redgamble –Activity Analysis
According to analysis at Symantec’s security center, when the Trojan.Redgamble infects your computer, the malware may drop the following files on the victim’s computer:
- %Windows%\WRMK.dll
- %Windows%\taskeng.exe
- %Windows%\addins\wrmk.dll
- %Windows%\addins\twain.dll
- %Windows%\addins\taskeng.exe
- %Windows%\Tasks\At1.job
The Trojan.Redgamble infection then proceeds to modify the following Windows Reigstry sub-keys and create entries in then to run tasks automatically and schedule tasks:
→ HKEY_LOCAL_MACHINE\software\Microsoft\SchedulingAgent\”LastTaskRun” = “HEX”
HKEY_LOCAL_MACHINE\system\CurrentControlSet\Services\Schedule\”NextAtJobId” = “3”
HKEY_LOCAL_MACHINE\system\CurrentControlSet\Services\Schedule\”AtTaskMaxHours” = “48”
HKEY_LOCAL_MACHINE\software\Microsoft\Internet Explorer\Main\”Start Page” = “URL”
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\”Start Page” = URL
The virus then creates a scheduled task to run the maliciosu files schtasks.exe and taskeng.exe fake processes with the following parameters:
→ %System%\schtasks.exe schtasks /create /tn “Microsoft\Windows\java\jued” /tr “%Windir%\taskeng.exe” /ru %USERNAME% /it /rl highest /sc minute /mo 1 /f
The malware then proceeds to check if the following types of executables are added as Windows Registry strings:
→ impactgame\poker\poker.exe
neowiz\pmang\common\pmlauncher.exe
cherrygame\poker\poker.exe
cherrygamej\poker\poker.exe
cherrygameh\poker\poker.exe
hangame\korean\baduki.exe
hangame\korean\poker7.exe
hangame\korean\highlow2.exe
hangame\korean\laspoker.exe
hangame\korean\hoola3.exe
When these scheduled tasks are executed, the malware injects it’s malicious DLL processes of the executables above if their strings are detected:
→ %Windir%\addins\wrmk.dll
%Windir%\addins\twain.dll
The malware then steals information from the games for online gambling and this information includes:
- Channel the user is in.
- The room the userparticipates in.
- The type of game played.
- The type of server.
