Leader Cllr Milan Radulovic says attacks on local authorities are happening almost daily.
Cyber thieves believed to be from Russia have attempted to hack into Broxtowe Borough Council's computer systems to steal personal information.
Councillor Milan Radulovic, leader of Broxtowe Borough Council, said local authorities are being targeted on an "almost daily basis" during the pandemic.
Thieves attempted to hack into the council's system which includes residents' personal information such as Council Tax details.
But the system's firewall held them off and no personal details were compromised.
The council's systems were down on Wednesday, February 3 and most of Thursday, February 4 while council staff dealt with the cyber attack. It is understood that the attack came from Russia.
Councillor Radulovic told Nottinghamshire Live: "There was an attempted hack on Broxtowe Borough Council but the firewall held it off.
"We think they were trying to get into the system. The system was down on Wednesday and most of Thursday while we were sorting it out.
"No one's details were compromised and they did not get in.
"It is an issue for every local authority, almost daily. We are constantly updating and upgrading systems and police are taking it seriously.
"I think it has got worse in Covid times because of some of the methods used are very current to the situation."
In response to the growing cyber threat in the UK, the Home Office is funding a nationwide network of Cyber Resilience Centres (CRCs).
CRCs are regional hubs supported by police forces, working with the private sector and academia.
They help businesses:
Learn more about cyber resilience;
Easily access Government recommended free tools from the National Cyber Security Centre (NCSC);
Learn how to procure good value private cyber security professional services.
Each centre provides advice and support regarding cyber security and protecting a business against cyber crime – with experts on hand to support visitors through all levels of the journey, whether it be protection against an attack, or support when an attack has already taken place. Businesses that join as members also gain access to free training and additional tools to help them stay safe online.
The CRC network aims to support businesses across the UK, with local students being offered work experience to help train them for a future role in cyber security.
Furthermore, CRCs have been designed to provide a targeted programme of work that will include training, ethical hacking, and recovery support via a range of trusted suppliers, who will provide everything from Cyber Essentials certification through to recovery from hacking and ransomware attacks.
