The cyber unit of Bogura police has arrested two students from Chandpur and Gopalganj since Thursday on charges of hacking more than 20 websites.

The arrestees are Bashir Ullah Sarder, 21, a 3rd-year student of a polytechnic institute in Gopalganj, and Azhar Uddin Abir, 19, a 2nd-year HSC student at a government college in Chandpur.

Police arrested Bashir from Gopalganj on Thursday and Abir from Chandpur on Friday, the law enforcers said, adding that the two used codenames -- FabiHaxor and 4zuc0d3r -- respectively and used to work for a hackers' group named Black Web.

The duo hacked various educational and business websites between December 2018 and January 2019, claimed police, adding they recovered 36 gigabytes of files related to hacking from the duo's computers.

A case was filed under the Digital Security Act with Bogura Police Station in this regard.

Emran Mahmud Tuhin, inspector of Detective Branch of Bogura police, claimed they recovered 3689 website defacements from the Black Web team. The team consists of eight to 10 hackers, he added.

Ali Ashraf Bhuiyan, superintendent of police in Bogura, also the head of the district's cyber unit police, said the hackers aimed to steal information from the hacked websites and wanted to be popular among local and international hackers' communities.

Police claimed to have recovered two desktops, one laptop and three mobile phones from the arrestees.

Police also prayed for a 5-day remand for the duo to a Bogura court which is yet to be heard.
