Hacked Device & Network Investigation Lawyers

Your phone behaves strangely. Emails you never sent appear in the outbox. Someone knows things they should not. You need to know what is on the device, and who put it there.

Our forensic examiners image phones, computers, email tenants and networks without altering them. Our lawyers turn the findings into preservation demands, claims and referrals.

Why It Matters

The device is the evidence. Most people destroy it in the first hour.

The instinct is to reset the phone or reinstall the laptop. That erases the proof of how the attacker got in and what they took.

Without that proof, there is no claim against the carrier, the platform or the person responsible. There is only a story.

Forensic imaging preserves the device as it was. Analysis then shows the malware, the sessions, the exfiltration and, often, the entry point.

The Landscape

Devices and inboxes are the entry point for most account theft.

FBI data on the attack patterns that start with a phone, a laptop or an email account.

31,675
Identity theft complaints reported to the FBI in 2025, up from 21,403 in 2024
971
SIM swap complaints in 2025, with $17.4 million in reported losses
47,794
Tech and customer support impersonation complaints in 2025
$2.13B
Losses from those impersonation schemes, many beginning with remote access to a device

Once a phone number is hijacked, the FBI notes, criminals use it to send “Forgot Password” requests and intercept one-time passcodes for the victim’s other accounts. Sources: FBI Internet Crime Complaint Center, 2025 Internet Crime Report; FBI IC3, SIM Swap Public Service Announcement.

How We Work

How a device investigation runs.

Preservation first. Analysis second. Legal action on the findings.

01

Stop using the device

Power it down. Do not reset it. Move communications to a clean device.

02

Forensic imaging

Examiners create verified images. The original is sealed and preserved.

03

Analysis

Malware, unauthorized sessions, exfiltration and installation dates are documented.

04

Third-party records

Carrier, platform and cloud logs are requested to corroborate the device findings.

05

Report and action

A report written for court or arbitration. Then claims, protective relief or referrals.

The Team Behind the Case

Investigators and lawyers, under one roof.

The investigative team

Retired federal law enforcement.

Former federal investigators and analysts who spent their careers on cyber and financial crime. They handle the forensics, the tracing and the contact with current law enforcement.

The legal team

Arbitrating cybercrime disputes since 2019.

Counsel in more than 130 arbitrations before AAA, JAMS and NAM, most arising from cybercrime and account takeovers. We try these cases on the evidence.

If It Is Happening Now

If you think your device is compromised.

What you do in the next hour decides whether the evidence survives.

Do
  • Power the device down and set it aside
  • Use a different, clean device for calls and password changes
  • Change email and banking passwords first, then everything else
  • Add a port-out PIN with your mobile carrier
  • Write down what you noticed and when
Do not
  • Factory reset, update or “scan” the device
  • Log into sensitive accounts from it
  • Confront a suspected insider before evidence is preserved
  • Let a repair shop or IT contractor wipe it
  • Assume a new phone solves the problem if the number or email is still compromised

FAQ

Frequently asked.

Common signs are unexpected password resets, unfamiliar sessions, battery drain, messages you did not send and contacts receiving odd requests.

Only forensic examination confirms it. Stop using the device and call.

Often. Installation dates, the receiving account and physical-access windows narrow it quickly.

Attribution is strongest when device findings are matched with carrier and platform records.

No. Examiners work from a verified image. The original is preserved as evidence.

Yes. Reports are prepared to evidentiary standards and examiners can testify.

Yes. Insider investigations cover access logs, file movement, personal cloud uploads and device activity, under privilege.

Email tenant review is a core part of the practice. Forwarding rules, OAuth grants and session logs usually tell the story.
