Serious Damage from Unauthorised Acts and the Law
Under section 3ZA of the Computer Misuse Act 1990, it is an offence to carry out any unauthorised act in relation to a computer that causes, or creates a significant risk of causing, serious damage of any kind.
- Damage to human welfare, national security, or the economy.
- Disruption to essential services such as energy, health, or transport.
- Severe loss of data or operational capability for organisations.
- Performed an unauthorised act on a computer system.
- Knew, or ought to have known, that the act was unauthorised.
- Intended to cause, or was reckless as to causing, serious damage.
Investigations can involve multiple agencies such as the Crown Prosecution Service (CPS), Serious Fraud Office (SFO), National Crime Agency (NCA), HMRC, or FCA, depending on the nature of the alleged damage. Digital forensics, IP tracing, server logs, and communications records often form the core evidence.
Our expert computer misuse act lawyers are trained to challenge the validity of such evidence, ensuring proper procedure, authorisation, and forensic accuracy. By addressing both legal and technical elements, Ashmans protects clients from misinterpretation and overreach.
