notorious hacking group owned by enigmagroup.org. It stands for Enigma Group Underground. Many claim it is a group of freemasons, hacking for the cause, while others claim its just a hacking association run by the administrators of this website. the staff and members claim the "EGU" doesn't exist, but attacks happen and their logo somehow gets on it.
oh no john, we've been targeted by the egu.
