Several government websites including those of the prime minister's office, the home ministry and the president's office have been hacked.

Around 10:00 pm yesterday, the homepage of those sites became replaced with a page demanding quota reform, along with a photo of the ongoing protests.

Google search result for the education ministry on Tuesday midnight showed 'Hacked by Bangladesh'.

However, when contacted on Wednesday morning, Posts, Telecommunications and Information Technology (ICT) Minister Mustafa Jabbar told UNB, "The intelligence department is working to find out the hackers involved. They (hackers) might have used the name of the agitating anti-quota platform."

By this time all the websites should be up and running well as the recovery works were initiated immediately after the incident happened last night.

"Websites across the world were being hacked in recent time. In line with those incidents the government websites might have been hacked," the minister added.

The websites of home ministry, education ministry and agriculture ministry and the same of public service commission (PSC) were found hacked around 12:00 am Wednesday.

Students and job seekers around the country have been demonstrating against the existing quota system in government jobs. In the last few days the protests escalated to violent confrontations with police in the Dhaka University area.
