Hackers of a group called Syrian Anonymous have managed to deface a total of 25 Nigerian government websites.
The list of hacked websites includes the ones of the Ministry of Justice, the Ministry of Finance, the Ministry of Education, the Ministry of Power, the Nigeria Christian Pilgrim Commission, the Federal Neuro Psychiatric Hospital Yaba, the Federal Ministry of Science and Technology and many others.
It’s uncertain why Syrian Anonymous has targeted these websites. As far as I know, there’s no direct conflict between Syria and Nigeria.
However, since the hackers are part of the Anonymous movement, it’s possible that they’ve targeted the Nigerian government for other reasons, not necessarily for something that has to do with Syria.
At the time of writing, many of the sites are still defaced. Some of them have been restored, while others have been shut down altogether. The complete list of websites and defacement mirrors are available on Pastebin.
