A council has been fined £100,000 after being accused of failing to repair a ‘vulnerability’ in the authority’s software which allowed hackers to access sensitive information.
The Information Commissioner’s Office (ICO) issued Gloucester City Council with the fine after a cyber attacker accessed council employees’ sensitive personal information.
The council said they were ‘disappointed’ by the decision which they would appeal.
The attacker took advantage of a weakness in the council’s website in July 2014, which led to over 30,000 emails being downloaded from council mailboxes.
The messages contained financial and sensitive information about council staff.
According to the ICO, the attacker — someone claiming to be part of the hacking group Anonymous — exploited the much publicised ‘Heartbleed’ software flaw.
The council’s failure to fix this vulnerability left personal information at risk and broke data protection law, said the ICO.
‘This was a serious oversight on the part of Gloucester City Council. The attack happened when the organisation was outsourcing their IT systems,’ Sally Anne Poole, group enforcement manager at the ICO.
‘A lack of oversight of this outsourcing, along with inadequate security measures on sensitive emails, left them vulnerable to an attack.’
The ICO investigation found that the council did not have sufficient processes in place to ensure its systems had been updated while changes to suppliers were made.
Responding to the ICO’s decision, Jon McGinty, managing director of Gloucester City Council, said: ‘The council is very disappointed with this decision by the Information Commissioner, and is considering its position whether to appeal.
‘The council takes the security of its data very seriously and remains of the view that it did take swift and reasonable steps in 2014 to prevent a data breach as soon as it was alerted to the existence of this hacking vulnerability and the availability of a security patch.
‘The Heartbleed vulnerability was a threat to businesses for some time before a patch was issued by software providers.’
‘There is insufficient evidence to show that the hacking event took place after the council became aware of the existence of the potential vulnerability,’ he continued.
‘The council believes that the penalty issued by the ICO will have a serious and detrimental impact on its finances, and the services that we will be able to provide to the residents of Gloucester in the future.
‘The council has invested more than £1m over the past 3 years to further improve its IT security and remains vigilant to the threats that all businesses face on a daily basis.
‘The council did account for the risk of this potential fine in its accounts for 2016-17 but nevertheless its payment will only result in money being taken away from the people of Gloucester and given to Treasury.’
