Characteristics
-- Update November 17, 2006 --
The 4899 DAT files are being released early as there is concern that this thread will spread globally. The web site hosting malware downloaded by this threat also contains Exploit-MS06-014 to automatically download and installs this virus on vulnerable systems.
--
On execution, this variant copies itself into %WinDir%\Uninstall folder as rundl132.exe and adds a load registry entry to activate itself on reboot. It also creates the following registry entries:
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DownloadManager
- HKEY_LOCAL_MACHINE\SOFTWARE\Soft\DownloadWWW\auto: "1"
It drops a .DLL file named RichDll.dll (detected as W32/HLLP.Philis.dll since the 4896 DATs) in %WinDir%. It then injects this dll into processes Explorer.exe and IExplore.exe. This dll is responsible for downloading the PWS-Lineage password stealing trojan from the following location:
- guajfskajiw.43242.com/[hidden]/a1.exe
W32/HLLP.Philis.bq searches for executable files and prepends its viral code to target files.
The virus creates files with the name "_desktop.ini" in every folder that it visits while looking for executable files to infect. This is created as a hidden system file and contains the date on which virus was executed to visit the folder in which the file resides. The date is shown in yyyy/mm/dd format.
The virus tries to spread via existing network shares. It searches for all active machines within the subnet. When it finds an active machine it sends an ICMP ping request and waits for a response.
After getting the ping response it tries to access the ADMIN$, IPC$ and any other shares that might exist on the machine.
If the virus is able to access a shared resource, it first copies "_desktop.ini" to the root of the share to mark the share as visited and then infects executables present in the share.
While infecting executables via a network share the virus does not limit itself to infecting specific file names as mentioned above. In the case of a shared printer, the viruses' infection routine effectively creates printer job to print the date as contained in "_desktop.ini" file that the virus tries to copy.
Symptoms
- These files have the system (S) and hidden (H) attributes set
- These files are detected as W32/HLLP.Philis.ini
Method of Infection
W32/HLLP.Philis.bq is a file infecting virus. Infection starts with manual execution of the binary. For spreading, the virus also relies on improperly configured/protected (open) shared drives.
Removal
AVERT recommends to always use latest DATs and engine. This threat will be cleaned if you have this combination.
