October 10, 2026: Emails, photographs, financial records and business documents are increasingly stored in the cloud rather than on individual devices. While cloud services offer convenience, they also create new challenges when cybercrime occurs and digital evidence must be traced.

This is where cloud forensics becomes essential.

Day 10 of the Centre for Police Technology (CPT) 31-Day Cybersecurity Knowledge Series explores how cloud forensics works, how criminals exploit cloud environments, and how investigators, organisations and individuals can respond.

What Is Cloud Forensics?

Cloud forensics is the process of identifying, collecting, preserving and analysing digital evidence stored or generated within cloud environments.

This evidence may include login records, emails, file-sharing activity, access logs, administrative changes and backups.

Unlike traditional digital forensics, investigators may not have direct access to the physical servers storing the data. They often depend on cloud service records, provider tools and lawful evidence-collection procedures.

The objective is to reconstruct what happened, identify suspicious activity and preserve evidence that can support an investigation.

How Do Criminals Exploit Cloud Services?

Criminals can misuse cloud platforms to commit fraud, steal information and conceal their activities.

Common examples include:

Account hijacking: Using stolen passwords or session tokens to access cloud accounts.
Business email compromise: Manipulating emails or mailbox rules to redirect payments.
Data theft: Downloading confidential files or sharing them without authorisation.
Ransomware attacks: Deleting or encrypting accessible data and targeting backups.
Phishing: Using deceptive links or cloud-hosted pages to steal login credentials.
Malicious infrastructure: Abusing cloud resources to host fraudulent websites or distribute harmful content.

Cloud services can also be used legitimately by criminals to store or transfer stolen information, making activity logs and access records important sources of investigative evidence.

How Can Police and Law Enforcement Agencies Use Cloud Forensics?

Cloud forensics helps police and law enforcement agencies (LEAs) reconstruct cybercrime and identify evidence that may not exist on a suspect’s or victim’s device.

Investigators can examine:

Login histories and authentication records to identify suspicious access.
Audit logs to trace file modifications, deletions and permission changes.
Emails and sharing records to investigate fraud and data theft.
Available backups and file versions to recover historical information.
Timestamps and related records to establish a sequence of events.

Investigators must obtain evidence lawfully, preserve original records, document collection methods and maintain a clear chain of custody.

A critical distinction is that a compromised account does not automatically prove who performed an action. Stolen credentials, shared accounts and hijacked sessions must be considered, and findings should be corroborated with other evidence.

How Can Everyday People Stay Safe?

Individuals can reduce cloud-related risks by adopting a few essential practices:

Use strong, unique passwords and enable multi-factor authentication.
Avoid clicking suspicious links or entering credentials on unfamiliar websites.
Review account login activity and connected devices regularly.
Check file-sharing permissions and remove access that is no longer needed.
Keep recovery information updated and secure.
Maintain independent backups of important files where appropriate.
Report suspicious account activity promptly and preserve relevant messages or alerts.

If an account is compromised, change credentials from a trusted device, revoke suspicious sessions where possible and contact the service provider through its official support channel.

What Should Companies Do?

Organisations need both preventive controls and forensic readiness. Important measures include:

Enable audit logging: Record relevant login, file-access and administrative activity.
Set retention policies: Keep essential records long enough to support investigations and legal obligations.
Strengthen access controls: Apply least privilege, multi-factor authentication and regular permission reviews.
Protect backups: Restrict access and maintain recovery copies that attackers cannot easily alter or delete.
Prepare incident-response procedures: Define how evidence will be preserved and obtained from cloud providers.
Train employees: Recognise phishing, account compromise and fraudulent payment requests.
Secure evidence: Protect collected logs against unauthorised changes and document the chain of custody.

Companies should also review their cloud providers’ logging capabilities, data-retention options and procedures for lawful evidence requests.

From Cloud Activity to Digital Evidence

Cloud forensics is not simply about recovering files. It is about understanding digital activity, tracing suspicious events and establishing what the available evidence can reliably prove.

For police and LEAs, it strengthens cybercrime investigations. For individuals, it highlights the importance of protecting online accounts. For organisations, it reinforces the need for secure configurations, reliable logs and effective incident-response planning.

In the cloud, security prevents incidents where possible, while forensic readiness helps establish what happened when prevention fails.
