The National Information Technology Development Agency (NITDA) says Nigeria is free from the WannaCry virus that has been affecting computers of organisations and institutions worldwide.
In a statement on Sunday in Abuja, Isa Ibrahim, director-general of NITDA, however called for sustained security from stakeholders to forestall future attacks.
On May 12, computers around the world were hit by the attack which has since affected over 200,000 computers about 150 countries
The ransomware attack targets computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency.
Ibrahim said that Nigeria was spared from the attack following sensitisation from relevant stakeholders.
“The management of NITDA would like to bring to the attention of Nigerians that the recent WannaCry or WannaCrypt ransomware attack has been contained,” he said.
“Nigeria was largely spared from the attack due to the massive enlightenment campaign, awareness and proactive measures put in place to swiftly deal with any reported incident.
“The efforts of all stakeholders in the information technology industry are highly commendable and appreciated.
“The attack which was considered to be one of the biggest cyber security attacks in recent history showed traces that Nigeria appeared to be isolated, as no major incident is reported in the country.
“We, therefore, call on all citizens, especially critical stakeholders in the IT industry, to support NITDA in this onerous task by always following best practices.
“They should be proactive in the way information and systems are handled as these will help in minimising risks of attacks as well as possible loss of vital information.”
The DG said that IT had become an integral part of Nigerians and that it required vigilance to ensure maximum protection.
He further called on users of outdated operating systems to upgrade to Windows 10 and obtain the latest protection patch, MS17-010, released by Microsoft.
He said there was hope for systems that had already been affected by the attack.
“For systems that have been attacked, tools have been developed to unlock the files locked by this ransomware,” he noted.
“The WannaDecrpyt or Wannakey can be used to unlock the file; they have been found to have successfully decrypted systems infected with the ransomware.”
