Over the last few days, several Muslim hacker groups have hacked government and financial websites in Sri Lanka in protest against the government’s attitude toward the violent clashes between Buddhists and Muslims.
As you can see in the graph below, there were hundreds of tweets over the weekend with the related hashtag #OpSriLanka.

For example, one Twitter account named Global Revolution called for the hacking of the Sri Lanka central bank website.

There is also a group page on Facebook named #OpSriLanka with 1,590 members. The main targets of the group are Sri Lankan government websites and official websites of the Buddhist population in Sri Lanka. The attack tools are mostly DDoS tools for computers and Android phones.

Additionally, on June 22, 2014, a group of hackers nicknamed Izzah Hackers leaked Sri Lankan government emails and passwords via Pastebin.

Sri Lanka is not alone. Muslim hacker groups are responsible for previous cyber-attacks against Myanmar (Burma) and the Central African Republic (CAR), protesting the killing of Muslims on religious grounds.
