The infamous Anonymous “Hacktivists” group would have succeeded in bringing down the website of the Central Bank of Nigeria yesterday evening but for additional security measure hurriedly installed by I.T engineers of the apex bank.
Investigations revealed that the CBN engineers in anticipation of a DDOs (Distributed Denial of Service) attack from Anonymous, had hurriedly deployed a protection technology from Cloudfare, a firm that sells application to protect websites from all manner of attacks. Consequently, every visit to the CBN website is first routed through the DDoS protection application before entrance access is granted.

This according to sources close to the CBN translates to five seconds delay in accessing the website, a situation which some erroneously attributed to hacking activities of the Anonymous group.
Confirming this development in a statement dismissing claims that website of the apex bank had been hacked, CBN Acting Director of Corporate Communications, Osita Nwanisobi issued a press statement titled, “CBN Website not hacked.

According to kaspersky.com, a Distributed Network Attacks are often referred to as Distributed Denial of Service (DDoS) attacks. … The DDoS attack will send multiple requests to the attacked web resource – with the aim of exceeding the website’s capacity to handle multiple requests… and prevent the website from functioning correctly.
The Anonymous “Hacktivists” had earlier succeeded in hacking and taking over the Twitter Account of the Nationbal Broadcasting Corporation of Nigeria (NBC).
