Former Vice-President Atiku Abubakar has raised concerns over the reported use of an outdated operating system on the Bimodal Voter Accreditation System (BVAS), warning that it could expose Nigeria’s electoral system to cybersecurity and operational risks ahead of the 2027 general elections. The former Vice-President also questioned why INEC had not upgraded the BVAS software ahead of the 2027 elections, despite what he described as the commission’s substantial budget. He warned that cybercriminals could exploit vulnerabilities in an outdated operating system to gain unauthorised access to devices or interfere with voter accreditation and polling unit results data before transmission. Atiku also warned that software defects in legacy systems could cause application crashes, particularly during periods of heavy usage, potentially delaying voter accreditation at polling units. According to Atiku, continuing to operate critical national electoral infrastructure on an end-of-life operating system could increase the system’s attack surface and expose the electoral process to avoidable risks.
