Third-Party Cyber Forensics & Attorney-Client Privilege

Protect your organization's attorney-client privilege after a cyber incident by engaging a qualified third-party forensics team. Using in-house IT for forensic investigations can compromise your legal protections.

Why Third-Party Forensics Matters for Privilege

When your company falls victim to a cyber attack, the temptation is to have your in-house IT department investigate. It seems faster and cheaper. However, this decision can have devastating legal consequences: using internal staff for forensic investigation can effectively waive your attorney-client privilege over the findings.

Here is the critical principle: when outside counsel retains a third-party forensics firm for the purpose of providing legal advice in anticipation of litigation, the resulting communications and work product are typically protected by attorney-client privilege. When the same investigation is conducted by in-house IT staff as part of normal business operations, that protection often disappears.

Petronella Technology Group serves as the third-party forensics team that outside counsel needs to preserve privilege. We are not a law firm, but we understand the legal landscape and conduct our investigations with litigation and admissibility in mind.

Key Legal Precedents

Several notable cases have established the importance of using third-party forensics to preserve privilege:

Genesco, Inc. v. Visa USA, Inc.

The court upheld attorney-client privilege because outside counsel retained the forensics firm (Stroz Friedberg) specifically for legal advice in anticipation of litigation, with clear documentation of the engagement purpose and scope.

Target Data Security Breach

Target successfully preserved privilege by using two distinct Verizon teams -- one for business remediation and one specifically retained through counsel for legal purposes. The clear separation between teams was critical to the court's ruling.

Experian Data Breach

Privilege was upheld because outside counsel clearly retained Mandiant for legal advice purposes, and the forensic report was delivered through attorneys rather than directly to Experian.

Premera Blue Cross Data Breach

In contrast, the court ruled against Premera's privilege claims because there was insufficient separation between the forensics team's legal advisory role and their normal business activities. This case highlights what happens when the engagement is not properly structured.

Frequently Asked Questions

Why can't we use our in-house IT team for forensic investigation?
When in-house IT investigates a breach, courts have consistently found that the work was conducted in the ordinary course of business rather than for legal advice. This classification strips the findings of attorney-client privilege protection, potentially exposing damaging information in litigation.
How should the engagement be structured to preserve privilege?
Your outside counsel should retain the third-party forensics firm directly for the purpose of providing legal advice. The engagement letter, scope of work, and reporting chain should all reflect this legal advisory purpose.
Can PTG handle both forensics and remediation?
Yes, but best practice is to clearly separate the forensic investigation scope from any remediation work. We can use distinct teams and documentation to maintain the separation that courts look for when evaluating privilege claims.
Does this apply to businesses in North Carolina?
Yes. While specific outcomes depend on the court and jurisdiction, the principles around third-party forensics and privilege apply broadly across federal and state courts, including those serving Raleigh-Durham and North Carolina.
What should we do first if we experience a breach?
Contact your outside counsel immediately. They should then retain a third-party forensics team like PTG to investigate. Do not have internal staff begin investigating until this structure is in place. Call PTG at 919-348-4912 for urgent forensic needs.

PTG Digital Forensics Methodology

PTG follows a rigorous, court-accepted digital forensics methodology developed through years of experience in law enforcement collaboration, litigation support, and corporate investigations. Our process adheres to the National Institute of Standards and Technology digital forensics guidelines and the Scientific Working Group on Digital Evidence standards, ensuring that all findings are defensible and admissible in legal proceedings. Every step of our investigation is documented in detail, creating a clear chain of custody and audit trail.

The forensic investigation process begins with evidence identification and preservation. Our examiners use forensic imaging tools and write-blocking hardware to create exact bit-for-bit copies of storage media without altering the original evidence. We capture volatile data from running systems when appropriate, including memory contents, network connections, and running processes. Each forensic image is verified using multiple hash algorithms to ensure complete integrity throughout the investigation.

During the analysis phase, our forensic examiners use specialized tools to examine file systems, recover deleted data, analyze application artifacts, examine email communications, review internet browsing history, analyze log files, and reconstruct timelines of user activity. We look for indicators of compromise, unauthorized access, data exfiltration, malware activity, and other relevant evidence depending on the nature of the investigation. Our analysis covers computers, servers, mobile devices, cloud accounts, and network infrastructure as needed to build a complete picture of events.

The final phase involves comprehensive reporting and, when needed, expert witness testimony. PTG forensic reports are written to be technically accurate while remaining understandable to non-technical readers including attorneys, judges, and juries. Reports include detailed methodology descriptions, findings with supporting evidence, timeline reconstructions, and conclusions supported by the evidence. Craig Petronella and our forensic team are available to provide depositions and courtroom testimony, explaining complex technical concepts in clear, accessible language that helps legal professionals and triers of fact understand the significance of digital evidence.

Our Approach to Cybersecurity

At Petronella Technology Group, cybersecurity is not just about installing antivirus software or setting up a firewall. We take a comprehensive, layered approach to security that addresses people, processes, and technology. Our methodology is built on industry-standard frameworks including NIST Cybersecurity Framework, CIS Controls, and MITRE ATT&CK, ensuring that your security program is aligned with the same standards used by Fortune 500 companies and government agencies. Every engagement begins with a thorough assessment of your current security posture, followed by a prioritized remediation roadmap that addresses your most critical risks first.

Our security operations team provides continuous monitoring through our Security Information and Event Management platform, which correlates events across your entire environment to detect threats in real time. When a potential threat is identified, our analysts investigate and respond immediately, often containing threats before they can cause damage. This proactive approach dramatically reduces the risk of successful cyberattacks and provides the rapid response capability that is essential in today's threat landscape.

We believe that employee awareness is one of the most important layers of defense. Human error remains the leading cause of data breaches, and no amount of technology can fully compensate for untrained employees. PTG provides comprehensive security awareness training programs that educate your team about phishing, social engineering, password security, data handling, and incident reporting. Our training programs include simulated phishing campaigns that test employee readiness and identify areas where additional education is needed, helping organizations build a strong security culture from the ground up.

Beyond prevention, PTG prepares organizations for the reality that breaches can occur despite the best defenses. Our incident response planning services help businesses develop, document, and test response procedures so that when an incident does occur, your team knows exactly what to do. From tabletop exercises to full incident simulations, we ensure that your organization is prepared to respond quickly and effectively, minimizing damage, preserving evidence, and meeting all regulatory notification requirements within required timeframes.

Our expert witness services cover depositions, court testimony, and technical consultation for attorneys.
How long does a typical digital forensic investigation take?
The duration of a digital forensic investigation depends on the scope, complexity, and volume of data involved. Simple investigations involving a single device may be completed in one to two weeks. Complex investigations involving multiple devices, network forensics, or cloud-based evidence may require several weeks to several months of analysis and documentation. PTG provides regular status updates and preliminary findings throughout the investigation process. Emergency investigations can be expedited when time-sensitive situations require immediate analysis, such as active data breaches or imminent legal deadlines.
What is the difference between computer forensics and incident response?
Incident response focuses on containing and remediating an active security incident to minimize damage and restore normal operations as quickly as possible. Computer forensics focuses on thoroughly analyzing digital evidence to determine what happened, how it happened, who was responsible, and what data was affected. While incident response is time-critical and operationally focused, forensics is methodical and evidence-focused. PTG provides both services, often working in parallel during a breach to simultaneously contain the incident and preserve evidence for investigation, insurance claims, and potential legal action.
