A mysterious hacker has hacked 250 Twitter accounts affiliated with the Isalmic State terror group in the past month, CNN Money reported.

The hacker launched an effort to sabotage IS-affiliated accounts by giving them LGBT pride makeovers in solidarity with the victim’s of last Sunday’s terrorist attack on a gay nightclub Orlando, Florida. Omar Mateen, the killer in the attack that left 49 dead and 53 wounded, pledged allegiance to the Islamic extremist group before initiating the massacre.

After the breach, the typically black and white terrorist Twitter pages displayed flamboyant rainbow images and pro-LGBT messages replaced Arabic writing.

The individual responsible for the hacking goes by the handle WauchulaGhost. He told CNN Money that in addition to this past week’s operation, he has posted explicit pornographic images to IS-affiliated accounts “to humiliate them.”
