Extrusion

Extrusion is a group of computer hackers. Using distributed-denial-of-service attacks, database exploitation, and remote access trojans primarily, the main intent of their activities were financial and notoriety gains.

It isn't known just how many members Extrusion has, though it has been revealed that the leader uses the online alias Plutonus, PlutonusHD, and as recently as December 2018, PlutonusDev.

Background

First appearing in 2016, Extrusion began their journey with 27 separate reported strains of a new kind of botnet that ran almost universally on Windows- and Linux- based operating systems, codenamed Nfluence. It is estimated that 365,000 or more devices were infected.

HiFriendo

HiFriendo was an undocumented PHP exploit that, after gaining access to a low-level console, would take advantage of a poorly crafted file and arbitrarily execute commands as root. HiFriendo in particular gave sudo access to attackers.
