Anonymous will not stop trolling Isis. But instead of calling for "boots on the ground" or increased drone strikes, the hacker collective is offering DIY guides on how to hack, "rickrolling" the terror group and now, replacing propaganda on their websites with click through links to "the No.1 Bitcoin Online Pharmacy" selling Prozac and Viagra.

Ghost Sec is a division of Anonymous, an organisation closely affiliated with the group. In a bid to counter Isis’ move onto the darknet to spread its message, Ghost Sec hacked one of its sites and left a message saying "Enhance your calm. Too many people are into this ISIS-stuff. Please gaze upon this lovely ad so we can upgrade our infrastructure to give you ISIS content you so desperately crave".

Basically, the message seems to be – stop it with all this Isis shit, visit this pharmacy, take more drugs and have sex for longer. As mission statements go it’s not bad really. Analysts have suggested that Isis are moving their websites onto the darknet in a bid to stop things like hackers taking over their sites and replacing the homepage with an ad for a online pharmacy, but there’s obviously still some work be done.
