WikiLeaks Revealed another Secret Document of CIA Malware called “OutlawCountry” that targets Linux Running Machines which Control and Redirect all outbound network traffic on the target computer to CIA controlled machines.
Few days Before WikiLeaks Revealed anather CIA Malware Called “ELSA” have an ability to Tracking Geo-Location information of Wi-Fi enabled Windows OS.
According to Leaked Document to perform this Direct Operation , this malware consist of kernel module that creates a hidden netfilter table in the Victims Linux Machine.
OutlawCountry Malware using this hidden netfilter table an operator can create rules that take precedence over existing netfilter/iptables rules and are concealed from an user or even system administrator.
OutlawCountry v1.0 only supports adding covert DNAT rules to the PREROUTING chain.
OutlawCountry Cause more Damage with Servers
OutlawCountry v1.0 contains one kernel module for 64-bit CentOS/RHEL 6.x.This module will only work with default kernels.
To perform successful attack on the target victims Linux Machine ,CIA need Shell access and root privileges are needed to install Malware.
Initial Installation need to select the appropriate kernel module for the Target machine.
CIA Test OutlawCountry Malware required 2 WEST and EAST Networks and 5 Hosts.
The module creates a new netfilter table with an obscure name. The new table allows certain rules to be created using the “iptables” command.
These rules take precedence over existing rules, and are only visible to an administrator if the table name is known. When the Operator removes the kernel module, the new table is also remove.
CIA operatives must compromise machines via other Methods before deploying this malware strain.
This Malware can be used both servers and Desktops which running under Linux Environment.
Once Victims Traffic successful Redirected to CIA operator Control, then CIA can able to sniff Victims Activities and it will be used for other Attacks and it leads to compromise entire Victims network.
If the Malware leads to occur more damage if its performed with Linux Based servers and it cause to sniff many users traffic which under the compromised server control.
The installation and persistence method of the malware is not described in detail in the document.
