Councils, schools and government offices were among global public sector and education organizations hit badly by DNS attacks last year – with nearly half reporting dealing with the issue cost them hundreds of thousands of pounds.
One in five (19 percent) of public sector sites and 11 percent of education bodies affected by DNS attacks say sensitive information was stolen. A fifth (20 percent) of public sector and 12 percent of educational victims also think intellectual property data was lost, while 10 percent of schools and colleges affected say they needed to take more than one day to recover.
This is in the context of yearly average costs of DNS security breaches to be now running at £1.7m ($2.2m) for organizations globally, with malware (35 percent), DDoS (32 percent), Cache Poisoning (23 percent), DNS Tunnelling (22 percent) and Zero-Day Exploits (19 percent) as the main threats.
