Process Information :
Process running in the name of "Traymgr.exe" and this is also hooked on to several other processes such as csrss.exe and lsass.exe
Symptoms :
Connects to the below mentioned server
- legion014.com
Once the trojan connects to the server, a remote attacker can spam itself using instant messenger (MSN). With complete control over the compromised computer, a remote attacker can use it to execute further commands specified by attacker.

This Trojan also attempts to create an autorun.inf file on the root of any accessible disk volumes.
The file "AutoRun.inf" is pointing to the malware binary executable. When the removable or networked drive is accessed from a machine supporting the Autorun feature, the malware is launched automatically.
The autorun.inf is configured to launch the Trojan file via the following command syntax.

A remote attacker can use the Trojan to perform various tasks:
- Gather system information Run IRC commands (PING, NICK, NOTICE, JOIN)
When the user is compromised, the malware binary connect to the IRC channels. Once the malware connects to the IRC server, it can take complete control over the compromised computer. A remote attacker can use it to execute malicious commands.It would also join an IRC channel to receive the following commands from the attacker:

BackDoor-DOQ is a backdoor that allows unauthorized access and control of a compromised computer to the remote attacker. This malware then opens a backdoor server that allows other computers to connect to the compromised user and control it in from the remote.
When executed, the following registry entry was created:
- [HKEY_LOCAL_MACHINE \SOFTWARE\Microsoft\Windows\CurrentVersion\Run\]
- MSN: %WinDir%\system.exe"
The above mentioned registry entry confirms that the malware binary is executed every time the system boots.
When executed the malware binary connects to the following site using remote port 80.
- 1.justca[removed].info
When the user is compromised, the malware binary connect to the IRC channels. Once the malware connects to the IRC server, it can take complete control over the compromised computer. A remote attacker can use it to execute malicious commands.
When executed the malware binary copies itself to the following system location:
- %WinDir%\system.exe
This malware binary also monitors for removable drives. When a removable drive is inserted into any compromised system the malware spreads by copying itself into that removable media connected to the compromised system and creates an "autorun.inf" file to execute itself whenever the device is connected to another system.
From the above screenshot, it’s clear that the malware copies itself to the removable drive in the following location.
- %RemovableDrive%\ SERVICES\SYSTEM\autorunme.exe
- %RemovableDrive%\AutORuN.inf
%WinDir% = \WINDOWS (Windows 9x/ME/XP/Vista), \WINNT (Windows NT/2000) %SystemDir% = \WINDOWS\SYSTEM (Windows 98/ME), \WINDOWS\SYSTEM32 (Windows XP/Vista), \WINNT\SYSTEM32 (Windows NT/2000) %ProgramFiles% = \Program Files, %SystemDrive% = Driver in which the Operating System is installed mostly C:\, %RemovableDrive% = Removable drive inserted into the system
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>------------------------------------------------------------------------------------------------
When run, this backdoor Trojan deletes itself and creates a process called msile.exe. msile.exe establishes an outbound connection with a remote server using IRC as follows:
PASS h4xg4ng NICK [00-USA-XP-9714670] USER SP2-ojd, followed by the name of the computer

The Trojan drops msile.exe into %windir%\system\. msile.exe is detected under the same name, BackDoor-DOQ. In addition, the Trojan drops a sysdrv32.sys file into %windir%\system32\drivers\. This file is detected as Generic Rootkit.g. Here %windir% is the Windows directory, in most cases, C:\Windows.
The Trojan creates the following registry keys to install msile.exe and sysdrv32.sys as system services:
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msile
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sysdrv32
Symptoms
- Presence of the IRC connection mentioned above
- Presence of the files and registry keys mentioned above
Method of Infection
- Trojans do not self-replicate. They spread manually, often under the premise that the executable is something beneficial.
- Trojans may also be received as a result of poor security practices, or un-patched machines and vulnerable systems.
- Distribution channels include IRC, peer-to-peer networks, email, newsgroups postings, etc.
Removal
All Users:
Use current engine and DAT files for detection and removal.
Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).

Overview -
This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.

When run, this backdoor Trojan deletes itself and creates a process called msile.exe. msile.exe establishes an outbound connection with a remote server using IRC as follows:
PASS h4xg4ng NICK [00-USA-XP-9714670] USER SP2-ojd, followed by the name of the computer

The Trojan drops msile.exe into %windir%\system\. msile.exe is detected under the same name, BackDoor-DOQ. In addition, the Trojan drops a sysdrv32.sys file into %windir%\system32\drivers\. This file is detected as Generic Rootkit.g. Here %windir% is the Windows directory, in most cases, C:\Windows.
The Trojan creates the following registry keys to install msile.exe and sysdrv32.sys as system services:
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msile
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sysdrv32
Symptoms
Symptoms -
- Presence of the IRC connection mentioned above
- Presence of the files and registry keys mentioned above

Method of Infection -
- Trojans do not self-replicate. They spread manually, often under the premise that the executable is something beneficial.
- Trojans may also be received as a result of poor security practices, or un-patched machines and vulnerable systems.
- Distribution channels include IRC, peer-to-peer networks, email, newsgroups postings, etc.
