Managing the finance impacts of a cyber incident

Use this module if your cyber incident involves activity such as finance and treasury management, income collection, and payments to residents and suppliers.


A serious cyber incident can have significant impacts on your council’s financial management, and in turn your ability to deliver critical services. The response to an incident typically requires an immediate, total shut down of IT services whilst the cause and impact are identified. This will cause significant impacts across service delivery and financial management, potentially for an extended period.

Even if an attack does not directly affect your core finance system, you may still experience significant impacts because of the incident and impacts on other systems (e.g. revenues, benefits, and housing rents).

Impacts are likely to include:

  • immediate operational risks due to lack of access to financial systems and data
  • revenue and cash flow impacts, with potential long-term impact on income collection and other revenue streams (e.g. benefits subsidy)
  • statutory and regulatory impacts, including reporting and audit
  • significant costs relating to the work of response and recovery, including costs due to increased demand and backlogs affecting services across the council.

Your key strategic actions

These are the critical actions to keep in focus throughout your response and recovery work. (Note: these are a strategic guide, not an exhaustive list of every action you should take.)

  • Do not expect a rapid recovery; plan for your systems to be impacted for weeks or months.
  • Expect services across the council to need additional support from the finance team, in addition to the work required to sustain and recover the finance operation itself.
  • Engage early with external partners (including auditors, banking providers, the Ministry of Housing, Communities and Local Government (MHCLG) and the Department for Work and Pensions (DWP)).
  • Prioritise financial processes with critical timings (e.g. payroll, month-end and year-end).
  • Establish clear teams and coordination for the financial response and recovery.
  • Clarify decision-making and governance for financial commitments during disruption.
  • Plan for continuity of essential services like payroll and urgent payments (e.g. benefits and payments to suppliers who have less financial resilience), including identifying where business continuity workarounds may introduce financial risk (e.g. benefits subsidy / local authority error).
  • Clarify insurance arrangements and engage insurers early.
  • Maintain communication with suppliers, debtors, and creditors.
  • Plan for income recovery and managing backlogs (e.g. council tax, rents).
  • Validate interim payment arrangements and make sure you have measures in place to mitigate fraud risks.
  • Ensure clear reconciliations between workaround systems and restored systems to avoid qualified accounts following recovery.
  • Account accurately for all response and recovery spending by using a unique emergency analysis code.
  • Capture learning for future resilience. 

Learning from previous incidents

Other councils who have experienced serious cyber incidents have found that:

  • Using the Cyber Grab Bag as a comprehensive guide has helped to deliver a thorough response and recovery.
  • It is essential to define clear priorities for business continuity arrangements, focused on the most critical impacts for the council and residents so that teams know where to focus while normal working is disrupted.
  • While many of your usual controls and processes will rely on your finance systems, in the event of system disruption or unavailability it is still possible to set up manual or workaround control processes using alternative tools and approaches (e.g. additional checks on payments, manual records etc).
  • It is helpful to keep an offline copy of your scheme of delegation. If this is unavailable after an incident, work quickly to recreate and validate this, so you are clear about decision making authority.
  • It is also essential to work closely with legal and governance teams to ensure that appropriate arrangements are in place for financial decision making and approvals during the period of disruption.
  • It is safest to assume that sensitive data will have been stolen as part of the attack. This could include sensitive finance data. It is important to prepare for mitigations against these data breaches, and only step those down when you are confident that they are no longer needed. These may last for longer than the service recovery itself.
