Elirks is a basic backdoor Trojan, first discovered in 2010, that is primarily used to steal information from
compromised systems. Mostly attacks using Elirks occurring in East Asia. One of the unique features of the
malware is that it retrieves its C2 address by accessing a pre-determined microblog service or SNS. Attackers
create accounts on those services and post encoded IP addresses or the domain names of real C2 servers in
advance of distributing the backdoor. Multiple Elirks variants using Japanese blog services for the last couple of
years.
