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.

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

→ impactgame\poker\poker.exe
