ISIS cyber-hacker Junaid Hussain has left behind a legacy of hate that spans the globe and continues to haunt the online world after his death. David Ibsen, director of the Counter Extremism Project, a US-based group combating terrorism and radicalisation, said: “Former British computer hacker Junaid Hussain was one of the most skilled and persuasive of ISIS’s recruiters, and propagandists. The number of attacks Hussain can be directly associated with by law enforcement officials likely pales when compared to the actual number he encouraged and engineered. Hussain also trained other ISIS operatives in the computer hacking skills. Despite the fact that Hussain was targeted and killed in 2015, a whole army of ISIS hackers continues, as do the ISIS propagandists and recruiters he trained."
