Digital Forensics

Case Study 1: Employee Data Theft & Insider Threat

The Challenge:

A financial services firm suspected that a departing employee had stolen sensitive client data before leaving the company. Suspicious activity was detected on the employee’s company laptop, but IT lacked the forensic capabilities to confirm the extent of the breach.

Our Approach:

• Hard drive forensic imaging to prevent data tampering.

• Analysis of file access logs and USB activity to track data exfiltration.

• Review of cloud storage sync logs to check if files were uploaded externally.

The Outcome:

Our forensic investigation revealed that the employee had transferred confidential client files to a personal USB drive and attempted to delete activity logs. The evidence was used in legal proceedings, and the company successfully prevented further misuse of stolen data.

Case Study 2: Ransomware Attack & Incident Response

The Challenge:

A UK-based retail company fell victim to a ransomware attack, with all customer transaction records encrypted overnight. The attackers demanded Bitcoin payment for decryption, and the company faced significant operational downtime.

Our Approach:

• Conducted memory forensics & malware analysis to identify the ransomware strain.

• Traced initial entry point (compromised employee email with a phishing attachment).

• Identified shadow copies & backup recovery options to restore encrypted data.

The Outcome:

We helped the company recover 92% of its data without paying the ransom. Security recommendations, including email security upgrades and network segmentation, were implemented to prevent future attacks.

Case Study 3: Fraud Investigation & Digital Evidence Recovery

The Challenge:
A legal firm required digital forensic evidence in a fraud investigation involving a business partner accused of misappropriating funds and falsifying invoices. The suspect denied any wrongdoing, and key financial records had been deleted.

Our Approach:
Performed disk forensics & deleted file recovery on the suspect’s work laptop.
Analysed email correspondence and document metadata for tampering.
Recovered altered invoices & hidden transactions stored in cloud backups.
The Outcome:
The forensic evidence we uncovered proved the fraudulent activity, leading to a successful legal case. The business recovered over £250,000 in stolen funds, and the suspect faced prosecution.
