Found Your Data on the Dark Web?
Verify the exposure. Preserve the evidence. Harden what's at risk.

You got an alert, or a friend or a monitoring service told you your information is on the dark web. The right next step is not to panic and not to ignore it — it is to find out what was actually exposed, whether it's still a live risk, and what to lock down first. We verify the leak, interpret what it means for your accounts, preserve the discovery as documentation you can use in a police or identity-theft report, and give you a concrete hardening plan. SleuthX, Inc. is an independent digital-forensics company.

A dark-web alert is an exposure signal, not a verdict.

It almost always means a company you did business with was breached and the stolen records — your email, and often a password, phone number, date of birth, or more — were posted or sold on a criminal forum.

That is worth taking seriously.

It is also frequently misread: many alerts point to old, recycled breach collections that were already mitigated by a password you changed years ago, and some scans overstate the danger to sell a subscription.

The first job is always to separate a fresh, actionable exposure from stale noise.

What a forensic review does that a free scan can't

A free scan answers one question — does your email appear in a known breach — and stops.

Tools like Have I Been Pwned do that well and for nothing, and they are a sensible first check.

A forensic review begins where the scan ends:

  1. Verify the exposure. Match the leaked record against known breach corpora, date it to a specific incident where possible, and identify exactly which fields were exposed — an email alone is low-risk; an email plus a reused password is urgent.
  2. Interpret the risk. Determine whether the exposed credentials are still valid on any account you hold, and which of your accounts the exposure actually threatens. Proportionate action beats panic.
  3. Preserve the evidence. Capture the posting or listing with its context and timestamps and preserve it under a defensible chain of custody, so if the exposure turns into fraud, extortion, or identity theft, you have documentation designed to support a police report, an FBI IC3 complaint, or an insurance or identity-theft claim.
  4. Harden what's at risk. Rotate exposed and reused passwords, move two-factor authentication to an app or hardware key, freeze credit where financial data or a Social Security number was involved, and reduce the public attack surface that made you a target.

What we don't promise

We do not claim to name the person who leaked your data or to remove it from the dark web — data that is already circulating on criminal forums cannot be deleted, and anyone who guarantees otherwise is selling a false promise.

Attribution on dark-web forums is the work of agencies with subpoena power; our role is to produce the evidentiary record that lets them act.

What we deliver is an analyst's honest read of what your exposure means and a defensible record of it — not a scare banner and not a guarantee.

Ongoing monitoring, so the next exposure reaches you fast

A one-time review tells you where you stand today.

Continuous monitoring is what turns the next breach from a months-late surprise into an alert you get in hours.

Our Protections layer watches for new breach and credential exposures and routes them into the same forensic response workflow, and every discovery can be preserved in the Evidence Vault with its chain of custody intact.

Frequently asked about dark-web exposure

My email address showed up in a dark-web alert. Does that mean I've been hacked?
Not necessarily, and the distinction matters. A dark-web alert almost always means one thing: a company you had an account with was breached, and the stolen records — which included your email address and often a password, phone number, or more — were posted or sold on a criminal forum. That is an exposure event, not proof that any of your own accounts is currently under someone else's control. The first job of a forensic review is to separate the two. We determine which breach the exposed record came from, how old it is, what fields were actually in it (an email alone is low-risk; an email plus a reused password is urgent), and whether the credentials are still valid on any account you hold. Only then can you act proportionately instead of panicking or, worse, ignoring a genuinely live exposure.
Is this leak real, or is a monitoring service just trying to scare me into buying something?
Both happen, which is exactly why verification comes first. A large share of dark-web 'alerts' point to old, recycled, or repackaged breach collections — the same credential dumps reshuffled and re-sold for years — and some marketing-driven scans overstate the risk to drive a subscription. A forensic examination checks the exposed record against the known breach corpora, dates it to a specific incident where possible, and tells you plainly whether the exposure is fresh and actionable or stale and already mitigated by a password you changed years ago. We do not sell fear. If your exposure is low-risk, we will tell you that and tell you the two or three things worth doing, rather than manufacturing an emergency.
Can you find out who posted my data or take down the criminal who leaked it?
Be clear-eyed about this. Attribution on dark-web forums is genuinely hard, and no honest analyst will promise to name the individual behind a breach or a paste. What we can do is document the exposure forensically: capture the posting or listing with its context and timestamps, preserve it under a defensible chain of custody, and interpret what it means for your risk. Where the exposure is tied to a crime against you — extortion, targeted harassment, identity theft — that preserved documentation is what your report to the FBI Internet Crime Complaint Center, local law enforcement, or a platform's abuse team is built on. Identifying and prosecuting the actor is the work of agencies with subpoena power; our role is to produce the evidentiary record that lets them act, not to overstate what a private examination can deliver.
What should I actually do right now, in order?
First, change the password on the exposed account and on any other account where you reused that password, and turn on app-based or hardware-key two-factor authentication everywhere it is offered — SMS codes are better than nothing but are the weakest option. Second, if a financial account or your Social Security number was in the exposure, place a free credit freeze with all three bureaus and consider a fraud alert; the Federal Trade Commission's IdentityTheft.gov walks through this at no cost. Third, preserve the evidence before it disappears — screenshots with context, the alert itself, dates — because if this turns into fraud or extortion you will need it. Fourth, decide whether ongoing monitoring is worth it so a future exposure reaches you in hours rather than after the damage. We can do the whole sequence with you, or hand you a checklist and let you run it yourself.
How is a SleuthX forensic review different from a free dark-web scan?
A free scan answers one question — 'does my email appear in a known breach?' — and stops there. That is a useful first signal, and services like Have I Been Pwned do it well for nothing. A forensic review starts where the scan ends: it interprets the exposure in the context of your specific accounts and risk, verifies whether the leaked credentials are still live, preserves the discovery as documentation you can use in a police report or an insurance or identity-theft claim, and produces a concrete hardening plan. The deliverable is not a red 'you're exposed' banner; it is an analyst's read of what the exposure actually means for you and a defensible record of it.
