Muslim hackers have targeted ISIS terrorist group’s propaganda network and published a list of almost 2,000 subscribers’ email addresses.

In what came as the latest blow to the online propaganda of ISIS, a Muslim hacking collective called Di5s3nSi0N attacked ISIS’s propaganda network.

Following numerous cyber attacks targeting Amaq news agency, ISIS issued a message on Friday night, claiming it had increased security.

“In response to recent events, we have imposed more stringent security measures on our systems,” the message read. “We can now handle email attacks or any type of hack.”

Di5s3nSi0N, which disabled the automated email service last month, attacked ISIS’s email again and in less than three hours, another email was sent out to the news agency’s subscribers, displaying the hackers’ logo and a warning.

“We have hacked the full ‘secure’ email list for Amaq,” it said. “Daesh...shall we call you dogs for your crimes or snakes for your cowardice? We are the bugs in your system.”

According to the Independent, the email contained a list of 1,784 subscribers’ email addresses.

“Challenge complete – too easy!” Di5s3nSi0N activists tweeted. “2,000 email subscribers hacked from Amaq...what is next?”

Amaq news agency is one of ISIS’s key propaganda outlets, which claims responsibility for terrorist attacks add issues updates from battles across the Middle East, Africa and Asia.
