WindowsUpdate.exe Gaming Trojan – How Did I Get It?

One way that this trojan may use to distribute itself is by utilising spam bots on gaming engines such as Steam which is widely used by PC games. The trojan is distributed mainly in Windows 7, Windows Xp and Vista computers.

Steam users may witness unfamiliar users adding them and promising them free game giveaways, as a part of a Black Friday or Christmas promotions. The message may feature a web link to the ‘giveaway’ which is actually the malicious link inserting the payload of the trojan.

Another way this trojan may use is via spam or spoof mails pretending to be from a website the user is registered in. Usually cybercriminals tend to collect user information via cookies or using other methods before actually infecting the computer itself.

Windows Update.exe Gaming Trojan – What Does It Do?

Symantec researchers report that once the trojan has been executed it modifies the following object:

→%System%\drivers\etc\hosts

It then creates a registry entry for the process WindowsUpdate.exe which is it`s payload to run every time the computer starts up. The registry key and its value is:

→“HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\Windows Update = “%AppData%\WindowsUpdate.exe”

This trojan then could try to run as Administrator on the computer.

Once done that, it starts deleting files:

→%AppData%:
WindowsUpdate.exe
pid.txt
pidloc.txt
.minecraft\lastlogin
Roaming\jagex_cache\reg\
Roaming\jagex_cache\regPin\PCNAME Pin.jpeg
%Temp%:
SysInfo.txt
PCNAME\_wallet.dat
wallet.dat
screens\screenshotDIGIT.jpeg
EBFile.exe
BFile
External Removable Drive:
\autorun.inf
\Sys.exe

The trojan also has the ability to terminate processes and clear user data. It also can interact with Steam and delete key steam files that may cause the user to log out.

This cyber threat may also delete or stop key system processes and services.

→Command interpreter
System configuration
Windows Task Manager
Windows Registry Editor

This infostealer then begins to gather info about the infected system:

→Computer name;CPU name;Server name;OS platform;OS version;.NET version;Predator version;Predator services status: keylogger, clipboard-logger, report frequency, stealers;Local date and time;Installed language;Installed AVs;Installed;Firewalls;Internal and External IPs

After doing so, the questionable cyber threat is reported to directly steal vital user information from the computer:

→Bitcoin wallet.dat;Email credentials;Browser credentials;Downloader credentials;Internet Downloader ;Manager credentials;Minecraft credentials;Steam credentials;PIN screenshots from RuneScape and EpicBot video games.

Also, symantec report that this trojan has the ability to perform other related tasks to its sole purpose which is to steal data:

→Display fake error messages;Log all keystrokes;Download and execute files;Visit websites;Delete cookies from IE and Firefox browsers;Block certain websites;Spread to removable drives

Since the severity of this threat it is highly advisable to take special precautions when some of the symptoms outlined above are seen and to immediately change all of the passwords on your accounts from a safe PC.
