The hacker group TeamPoison has released data taken in a recent attack on the Nigeria National Assembly, listing the hack as a part of the ongoing OpNigeria campaign.

TeamPoison - a hacker group that, while autonomous, is often taken as an affiliate of the larger collective Anonymous - released the data on Wednesday via a post on Pastebin.

The data was taken from site's server and included database information and the usernames and encrypted passwords of several user accounts.

"Tonight we've got some databases from some influential sites in Nigeria. Contained within are admin passwords as well as tons of other information from these databases. Revolution is the only way for evolution; Nigeria, raise up and confront your oppressors," read TeamPoison's statement.

OpNigeria was previously announced by the Anonymous collective in January 2012. In its statement Anonymous clarified that the operation would primarily target the Jama'atu Ahlis Sunna Lidda'awati wal-Jihad (People Committed to the Propagation of the Prophet's Teachings and Jihad) - a fragmented group commonly referred to as Boko Haram.

The collective later clarified that it would look to work with groups such as Amnesty International to bring members of Boko Haram to justice.

Though the site is still under construction, the operation will follow the pattern previously seen in the collective's ongoing anti-nazi OpBlitzkrieg campaign. OpNigeria will see Anonymous hackers target Boko Haram's networks and emails, publishing all the data taken on the central site.

"We will use this database we create, and along with Amnesty International we will provide evidence to the ICC in the Hague. If the Nigerian government can not catch and bring to justice these despicable people, then Anonymous and the world will," read Anonymous's statement.

Boko Haram is a Nigerian militant Islamist group with the central ideology that: "Anyone who is not governed by what Allah has revealed is among the transgressors" - an idea the group has interpreted to mean it is forbidden for Muslims to take part in any political or social activity in Western society.

Under the leadership of Mohammed Yusuf the group was originally fairly unified, with a central base in the north-eastern city of Maiduguri. However, following their leader's arrest and death in 2009 the group broke apart into fragmented cells, each with their own nuances and beliefs.
