Bad Leaver Digital Forensics: Key Investigation Techniques
Posted on 3rd June 2024 at 16:10
The term "bad leaver" refers to an employee who leaves an organisation under negative circumstances, often taking sensitive data or causing disruption as they exit. Digital forensics plays a crucial role in investigating and mitigating the risks associated with such departures.
Understanding the Bad Leaver Phenomenon
A bad leaver can be an employee who resigns, is terminated, or leaves under contentious circumstances. Unlike a "good leaver," who exits the company on amicable terms, a bad leaver might engage in malicious activities, such as:
Data Theft: Stealing confidential information, client lists, or intellectual property.
Data Destruction: Deleting or corrupting important files and records.
System Sabotage: Tampering with IT systems, introducing malware, or causing operational disruptions.
The motivations behind such actions can vary, ranging from personal vendettas to financial gain or competitive advantage. Regardless of the reason, the aftermath can be devastating for an organisation, highlighting the need for robust digital forensic measures.
The Role of Digital Forensics
Digital forensics is the practice of collecting, analysing, and preserving electronic data to uncover and investigate digital crimes. At Tower Forensics, we specialise in providing comprehensive digital forensic services to help organisations navigate the complexities of bad leaver incidents. Here’s how we approach the role of digital forensics in these situations:
Identify Malicious Activities: Detecting unauthorised access, data exfiltration, or sabotage attempts. This involves scrutinising system logs, user’s digital activities, and access patterns to pinpoint any unusual or unauthorised actions.
Gather All Types of Digital Evidence: Collecting digital evidence is a critical step. We gather a wide range of evidence, including:
System Logs: Detailed records of system activities.
Digital Devices: Seize and secure Corporate digital devices that the Bad Leaver had access to.
File Metadata: Information about file creation, modification, and access.
Network Traffic: Data packets and transfer logs to trace data movement.
Emails and Communications: Correspondence that might indicate malicious intent.
Cloud Data: Forensically acquire data held in the cloud at the earliest opportunity to ensure data is retained and not lost.
Deleted Files: Recovering files that may have been intentionally deleted.
Contacting Subject Matter Experts: Engaging experts is crucial for a thorough investigation. At Tower Forensics, we collaborate with organisations and legal advisors to ensure a comprehensive and accurate investigation.
Gather Evidence: Utilise SME’s to forensically acquire digital evidence so that can be used in legal proceedings or internal investigations without suggestion of wrongdoing or data changes. This involves maintaining the integrity of the data, following strict chain-of-custody protocols, and ensuring that all evidence is admissible in court.
Mitigate Damage: Assessing the extent of the damage and implementing measures to prevent further harm. This includes identifying compromised systems, isolating affected areas, and initiating recovery procedures.
Enhance Security: Strengthening the organisation’s security posture to prevent future incidents. This involves conducting thorough security audits, implementing advanced monitoring tools, and educating employees on best practices.

To effectively handle bad leaver incidents, organisations should adopt a proactive and comprehensive strategy. Here are some best practices we recommend at Tower Forensics:

Clear Policies: Establish clear policies regarding data access, usage, and exit procedures.
