Data Theft & Information Leakage
Investigating the Unauthorised Access, Transfer and Disclosure of Sensitive Information.
Data Theft & Information Leakage.
Data theft is often insidious, carried out over weeks or months by trusted insiders or sophisticated external actors who understand where high-value assets reside.
Our investigative workflow uncovers hidden data movements across endpoints, cloud storage synchronizations, USB connections, and encrypted messaging channels, establishing court-admissible facts.
Key Incident Indicators
Unusual volumes of file downloads, copying or transfers
Unauthorised access to confidential or restricted information
Unexplained use of USB devices or removable storage media
Unusual uploads to personal email, cloud storage or external platforms
Abnormal file synchronisation or data transfer activity
Suspicious access to sensitive repositories outside normal working patterns
Unexpected changes in data access permissions
Reports of confidential information appearing outside authorised environments
Key Challenges & Stellar Forensic Interventions
Detecting Unauthorised Data Activity
Unusual access, file activity, copying or transfer of sensitive information may indicate that data has been accessed or moved outside its intended use. Establishing what occurred requires analysis of relevant digital activity across affected systems and users.
Investigating Suspected Employee Data Theft
Employees, contractors or other authorised users may have legitimate access to sensitive information but misuse that access to copy, retain or transfer company data before departure.
Understanding How Information May Have Left the Organisation
Sensitive information may be transferred through email, cloud storage, removable media, messaging platforms, web services or shadow IT channels.
Establishing the Scope of Potential Information Leakage
An organisation needs to understand which specific datasets were involved, which users or systems were affected, when activity occurred, and whether exposure is continuing.
Responding to Insider Threats and Departing Employee Concerns
Employee departures, anomalous user downloads, suspected policy violations, or concerns regarding trade secrets require rapid, evidence-led triage within agreed legal boundaries.
