What do cyber investigators actually do?
Online harassment, fraud and scams leave traces, but few people know where to look or what a court will accept. We investigate defamation and smear campaigns, threats, anonymous attackers, fraud and stolen money. Our investigators combine open-source research, technical analysis of emails, accounts, domains and transactions, and support for legal process. Every case ends in a report you can use with your attorney, the police or your bank. When the evidence cannot get to a name, we tell you plainly.
Cyber investigations
Expose the people behind the attack
Defamation and smear campaigns, anonymous attackers, threats and attacks on executives. We work out who is responsible and document it for court.
Online defamation and smear campaigns
Fake reviews, smear campaigns, impersonation and coordinated harassment. We find the people and accounts behind them and document it for your attorney.
Online defamation and harassment →Identify anonymous accounts
We identify the people behind anonymous accounts, fake emails and IP addresses. We can identify trolls even when they hide behind a VPN, as long as there is a suspect.

Threats, stalking and impersonation aimed at executives, public figures and their families.
Executive and celebrity threats →Litigation support
Evidence, reports, subpoena support and expert testimony for attorneys building a case.

Fraudulent payments, hijacked inboxes, stolen crypto and hidden assets. We follow the funds. For wire fraud we work with banks, and we prepare findings for insurers and law enforcement.
Wire fraud and financial crime
We work with banks on wire fraud, tracing where the money went and identifying who received it. Time matters, so contact us as soon as you spot it.

What every investigation includes
- Evidence preserved. We make forensic copies and keep the originals unchanged, so no one can argue the evidence was altered.
- A written record of every step. We log who handled each item, what we did with it and what we found, so a third party can repeat our work and reach the same result.
- Findings with confidence levels. Our reports separate confirmed facts from reasoned inferences and say how strong each one is.
- Lawful methods only. We do not hack accounts or devices. Evidence gained that way would harm your case.

Common questions
Cyber investigation FAQ
Can you investigate defamation and smear campaigns?
Yes. We identify who is behind fake reviews, smear campaigns, impersonation and coordinated harassment, and we document the evidence so your attorney can act on it. We cannot promise an outcome in court.
Can you find who is behind an anonymous account?
Often, but not always. Open-source research often identifies the person: we link usernames, domains, email addresses and public records, and we score each suspect on the evidence. We state the confidence of each finding. We can identify trolls even when they use a VPN, as long as there is a suspect. When only the platform holds the answer, we use a lawful, controlled engagement to get it another way, and we support your attorney if the case goes to court.
Can you recover stolen cryptocurrency?
We trace where the funds went and prepare evidence for exchanges and law enforcement. We cannot promise recovery, and speed matters, so contact us as soon as you notice the theft.
Is a cyber investigation legal?
Yes. We use lawful methods only, and we advise clients on what evidence will hold up. Rexxfield is not a law firm, so legal advice and filings come from your attorney.
How much does an investigation cost?
Background investigations start at USD 2,000, digital investigations at USD 5,000 and corporate investigations at USD 10,000. After a free, confidential consultation we send a clear scope and fixed fee. See our fees page for details.
Who do you work with?
Most of our work is for companies, executives, attorneys and insurers. We also help individuals. We do not serve the gambling or sex industries, or other objectionable businesses.
