TROJ_FAKEAV.GAC

This Trojan connects to a website to send and receive information.

It displays fake alerts that warn users of infection. It also displays fake scanning results of the affected system. It then asks for users to purchase it once scanning is completed. If users decide to purchase the rogue product, users are directed to a certain website asking for sensitive information, such as credit card numbers.

Installation

This Trojan drops the following copies of itself into the affected system:

• %System Root%\Documents and Settings\All Users\Application Data\f0171\MS314.exe

(Note: %System Root% is the root folder, which is usually C:\. It is also where the operating system is located.)

It creates the following folders:

• %Application Data%\My Security Shield
• %System Root%\Documents and Settings\All Users\Application Data\MSEHSFS
• %System Root%\Documents and Settings\All Users\Application Data\f0171
• %Desktop%\Quarantine Items
• %Desktop%\MSSSys
• %Desktop%\BackUp

(Note: %Application Data% is the current user's Application Data folder, which is usually C:\Windows\Profiles\{user name}\Application Data on Windows 98 and ME, C:\WINNT\Profiles\{user name}\Application Data on Windows NT, and C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000, XP, and Server 2003.. %System Root% is the root folder, which is usually C:\. It is also where the operating system is located.. %Desktop% is the current user's desktop, which is usually C:\Windows\Profiles\{user name}\Desktop on Windows 98 and ME, C:\WINNT\Profiles\{user name}\Desktop on Windows NT, and C:\Documents and Settings\{User Name}\Desktop on Windows 2000, XP, and Server 2003.)

Autostart Technique

This Trojan adds the following registry entries to enable its automatic execution at every system startup:

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Run
My Security Shield = "%System Root%\Documents and Settings\All Users\Application Data\f0171\MS314.exe" /s /d

It drops the following files:

• %Start Menu%\\My Security Shield.lnk - shortcut to its copy
• %Start Menu%\\Programs\\My Security Shield.lnk- shortcut to its copy
• %Desktop%\\57.mof - non-malicious component
• %Desktop%\\My Security Shield.lnk- shortcut to its copy
• %Application Data%\\Microsoft\\Internet Explorer\\Quick Launch\\My Security Shield.lnk - shortcut to its copy
• %User Profile%\\Recent\\DBOLE.sys - non-malicious component
• %User Profile%\\Recent\\pal.exe - non-malicious component
• %User Profile%\\Recent\\PE.exe - non-malicious component
• %User Profile%\\Recent\\DBOLE.drv - non-malicious component
• %User Profile%\\Recent\\fan.dll - non-malicious component
• %User Profile%\\Recent\\hymt.drv - non-malicious component
• %User Profile%\recent\SICKBOY.sys - non-malicious component
• %User Profile%\recent\ANTIGEN.sys - non-malicious component
• %User Profile%\recent\energy.drv - non-malicious component
• %User Profile%\recent\ANTIGEN.dll - non-malicious component

(Note: %Start Menu% is the current user's Start Menu folder, which is usually C:\Windows\Profiles\{user name}\Start Menu on Windows 98 and ME, C:\WINNT\Profiles\{user name}\Start Menu on Windows NT and C:\Windows\Start Menu or C:\Documents and Settings\{User name}\Start Menu on Windows 2000, XP, and Server 2003.. %Desktop% is the current user's desktop, which is usually C:\Windows\Profiles\{user name}\Desktop on Windows 98 and ME, C:\WINNT\Profiles\{user name}\Desktop on Windows NT, and C:\Documents and Settings\{User Name}\Desktop on Windows 2000, XP, and Server 2003.. %Application Data% is the current user's Application Data folder, which is usually C:\Windows\Profiles\{user name}\Application Data on Windows 98 and ME, C:\WINNT\Profiles\{user name}\Application Data on Windows NT, and C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000, XP, and Server 2003.. %User Profile% is the current user's profile folder, which is usually C:\Windows\Profiles\{user name} on Windows 98 and ME, C:\WINNT\Profiles\{user name} on Windows NT, and C:\Documents and Settings\{user name} on Windows 2000, XP, and Server 2003.)
