One of the CIA Cyberweapon Called “Pandemic” Document Leaked by Vault 7 Projects of WikiLeaks.This Malware tool Specifically interact and run as kernel shellcode to install File system Driver.
This Malware will the attack the Victim Machine if user accesses the file via SMB, the Payload files will be Replaced to the Actual Target file .This Function will work in Read-only Mode.
“Pandemic” Malware’s Actual Goal is to be installed in Victims Machine when the Victims remote users use SMB to download/execute PE files.
According the Leaked CIA’s “Pandemic” Secret Document, It won’t make sense and it will not replace the Target file if the file is opened on the machine Where Pandemic is running on.
Pandemic Leads to Unchanged the File But Replaced
While “Pandemic” entered into the Victims Machine when user accesses the file via SMB,it will not do any physical Changes in the Target Files.
According to leaked Source of Vault 7 ,Users that are targeted by Pandemic, and use SMB to download the targeted file, will receive the ‘replacement’ file.
“Pandemic” can operate both 32 and 64 bit .CONOP(Concept of Operation) done by the CIA ,version 1.0 can works only on 64 bit targets.
A “Pandemic” Tool ability to Replace up to 20 files by using the Latest version of Pandemic 1.0.As per the Document “The 1.1 builder will dynamically re-size the output bin file to the appropriate size needed to contain all the payload data, so there is no longer an absolute cap on total output bin size. There is, however, a hard-coded cap on the maximum size a single replacement file can be (800MB). Pandemic 1.1 also made some changes to improve the robustness of the swapping mechanism”
File Information of “Pandemic”
First version (1.0) of the “Pandemic” Developed on17 April, 2014 by Engineering Development Group of CIA and the versions has been updated on16 January 2015 with some extra capability including Replaced files up to 20 in victims machines.
Files Executable and DLL looks like Pandemic_Builder.exe, Control.dll
According to the Leaked Sources File Registry access by “Pandemic” Performs like below“S//NF) Pandemic registers a minifilter driver using Windows’ Flt* functions. As a result, FltMgr requires that all drivers registering as minifilters contain certain registry keys. Pandemic uses the ‘Null’ service key (on all Windows systems) as its own driver service key. Pandemic will create 2 sub keys and 3 values under the ‘Null’ service key in the registry. These values and sub keys are deleted when Pandemic is uninstalled at the end of its configured run timer, or when it is uninstalled via a special F&F (v2) DLL.These keys will NOT//NOT be deleted if the system is rebooted before the aforementioned scenarios occur”
