Ghost Squad 

A small group of Blackhat hackers that cause havoc on popular Instagram pages, small companies and anybody they disagree with. They typically go after targets with a large following on social media sites and applications like Instagram, Twitter or Facebook. The organizations end goal is unclear, but the one thing that is clear about these hackers is that if you come across them DO NOT piss them off.

The Ghost Squad hackers took down another popular Instagram account, this the tenth time this week!

Ghost Squad (GS4) 

Underground Hip-Hop group formed in 2005 in Macon, GA. GS4 consists of the four original members of the group, Chris Wind, Hot Flame, D'andre O'range (formerly known as Orange B.), and Legacy aka Double LL's. Members of the group have since released individual mixtapes, worked with George Clinton of P-Funk, and performed in venues from across the country. They are best known for their "Graveyard Vol. 1" mixtape. "Ghost Squad" was abbreviated to "GS4" to only include the four original members whereas artists such as Spit Phi have also been included in the Ghost collective from time to time. It was also abbreviated to prevent confusion with the Sega arcade game with same name, though it was released long after the group had been formed.

Ghost Squad (GS4) isn't your average Mactown group!
