TECHNICAL DETAILS
Installation
This Trojan Spy drops the following copies of itself into the affected system and executes them:
- %User Temp%\{Random characters}.exe
(Note: %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local\Temp on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)
It drops the following files:
- %User Temp%\{Random characters}.dat
- %User Temp%\~{File name that ran explorer.exe}.tmp
(Note: %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local\Temp on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)
It adds the following processes:
- {Malware file name} /C
- {Malware copy} /C
- {Malware copy} /W
- %Windows%\explorer.exe (%System\mobsync.exe or %Program Files%\Internet Explorer\iexplore.exe if not found)
- "%System%\schtasks.exe" /create /tn {GUID} /tr "\"{Malware copy}\"" /sc HOURLY /mo 5 /F
- "%System%\cmd.exe" /c ping.exe -n 6 127.0.0.1 & type "%System%\calc.exe" > "{Malware file name}" (overwriting itself with calc.exe)
(Note: %Program Files% is the default Program Files folder, usually C:\Program Files in Windows 2000(32-bit), Server 2003(32-bit), XP, Vista(64-bit), 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit) , or C:\Program Files (x86) in Windows XP(64-bit), Vista(64-bit), 7(64-bit), 8(64-bit), 8.1(64-bit), 2008(64-bit), 2012(64-bit) and 10(64-bit).. %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.)
It adds the following mutexes to ensure that only one of its copies runs at any one time:
- Global\{GUID}
Autostart Technique
This Trojan Spy adds the following registry entries to enable its automatic execution at every system startup:
HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Run
{Random characters} = {Malware copy}
