WikiLeaks’ latest Vault7 release of leaked CIA documents detailing its hacking tools reveals malware called OutlawCountry that targets Linux systems.

OutlawCountry is described in documents dated June 4, 2015 as a kernel module for Linux 2.6 that allows CIA operators to redirect outbound traffic to a server they control by creating an hidden netfilter or iptables table.
