At least twenty suspects have been arrested for hacking the 2025 Computer-based test examinations conducted by the Joint Admissions and Matriculation Board (JAMB).
The suspects were nabbed by operatives of the Department of State Services (DSS) and the Nigerian Police Force, in Abuja,

The suspects are part of a syndicate believed to have over 100 persons, who specialise in hacking the computer servers of examination bodies like JAMB and the National Examinations Council (NECO).

According to security sources, the suspects have confessed to sabotaging the CBT system to discredit JAMB and discourage students from using CBT for future examinations to be conducted by NECO and the West African Examination Council (WAEC).

The entire hacking process was to influence high scores for special candidates who paid between ₦700,000 and ₦2 million.
It was gathered that several members of the syndicate own private schools and colleges, and make huge sums of money from their special centres.

This comes two weeks after JAMB released the 2025 UTME results.

An analysis showed that more than 78 per cent of candidates scored less than 200 points out of the 400 maximum points obtainable.
On May 14, Ishaq Oloyede, JAMB registrar, said that the results of 379,997 candidates across 157 centres in its Lagos and South-East zones were affected.

He cited faulty server updates that prevented candidate responses from being uploaded during the first three days of the exam.

Oloyede said the problem, which was caused by one of its technical service providers, went undetected before the results were released.

The board conducted a resit examination, starting from May 16 and extending beyond May 19.
