Oggetto: CIA Outlaw Country attack against CentOS / Rhel  (and Fedora?)
 Is this credible?

Wikileaks released a document about an attack against CentOS / Rhel.

https://wikileaks.org/vault7/#OutlawCountry

Here's the text, there are some docs there also.

OutlawCountry
29 June, 2017

Today, June 29th 2017, WikiLeaks publishes documents from the
OutlawCountry project of the CIA that targets computers running the
Linux operating system. OutlawCountry allows for the redirection of all
outbound network traffic on the target computer to CIA controlled
machines for ex- and infiltration purposes. The malware consists of a
kernel module that creates a hidden netfilter table on a Linux target;
with knowledge of the table name, an operator can create rules that
take precedence over existing netfilter/iptables rules and are
concealed from an user or even system administrator.

The installation and persistence method of the malware is not described
in detail in the document; an operator will have to rely on the
available CIA exploits and backdoors to inject the kernel module into a
target operating system. OutlawCountry v1.0 contains one kernel module
for 64-bit CentOS/RHEL 6.x; this module will only work with default
kernels. Also, OutlawCountry v1.0 only supports adding covert DNAT
rules to the PREROUTING chain.


My first take is that this doesn't represent a very serious threat.??Do
you disagree?

It's not much of a secret that you can mess with a system if you have
root access...

and in case you restart the box, this hack is gone :-)

The module doesn't represent an unknown security flaw, so my inclination 
is to say "no."  I'd also note that if your systems aren't
extremely
old, they probably boot via UEFI, and support Secure Boot.  Such a 
system will not load unsigned modules.
