Hackers target Kent Council Council's computer systems
Kent County Council has been victim to dozens of attempted cyber attacks and three bogus callers trying to access personal information.
Figures obtained by BBC Radio Kent show criminals regularly tried to access personal information the council holds.
The authority said it regularly reviewed its electronic safeguards.
Over the past two years it said it had detected 26 phishing and 50 malicious software attacks which were not automatically blocked.
In its response to the Freedom of Information request, the council said it had "pre-emptively blocked" an attack from China on 27 February 2012.
It had been warned by Unisys, the company which manages its network, that a range of Chinese IP addresses were attempting to attack targets in the UK.
A council spokesman said the authority took the security of its computer systems very seriously.
He said: "The arrangements put in place to safeguard data held electronically are regularly reviewed and tested as the challenge of this kind of security is evolving all the time.
"As potential threats can come in different guises, and from anywhere around the world, we are careful not to discuss its security set-up so that its arrangements are not compromised."
The authority said it had paid a local IT company to test the security of its internal systems in May 2012.
