What Is The Lockdown?

The Mirror shows you what’s publicly findable. The Lockdown goes one layer deeper — into the places you can’t search yourself. Corporate data dumps, credential pair databases, stealer log dumps traded on Telegram and Russian underground channels, dark forum archives, and pastebin repositories that circulate long after the original breach is forgotten.

Have you ever worked at a company that was breached? Read Why Using AI for OSINT Leaves a Trail — it explains how modern investigators trace digital behaviour and why your corporate exposure may extend far beyond what you expect.

The key question The Lockdown answers: based on what’s circulating, which of your accounts are at realistic risk of takeover right now — and what should you do about it? Leaked credentials don’t just enable password-based attacks — they feed AI-driven KYC bypass and vishing attacks that defeat the controls most people trust.

Investigation Foundation Included:

  • Username & Account Discovery Across Platforms and Forums
  • Google Trace & Associated Account Mapping
  • Social Media Profile Assessment
  • Profile Photo Cross-Reference & Reverse Image Search
  • Dark Web & Breach Database Search
  • Data Broker Exposure Assessment + Opt-Out Instructions
  • Per-Category Risk Assessment & Prioritized Action Plan

The Lockdown includes the full Mirror investigation (€595) as its foundation, then goes deeper into credential markets, dark forums, and corporate leak databases.

What’s included in The Lockdown

Corporate Leak Investigation

Breach data cross-referenced against your employer and company name — looking for credential pairs, internal email formats, and references to you in corporate data dumps.

Credential Pair Analysis

We look for where your username and password appear together in circulating datasets — not just isolated mentions, but complete credential pairs that enable account takeover.

Stealer Log Exposure Mapping

Beyond breach databases, we check your credentials against stealer log indexes that Have I Been Pwned does not catalogue. These are live logs traded on Telegram and the Russian underground, often containing session cookies that bypass password resets and MFA.

Pastebin & Dark Forum Reference Search

Targeted search for your name, email, and username in paste dumps and closed forum posts that circulate on dark web channels.

Account Takeover Risk Assessment

Based on findings, we identify which specific accounts are at realistic risk and explain exactly why — no generic advice.

Personalised Security Recommendations

Tool and setup advice based specifically on what was found — the right password manager, the right authentication method, based on your actual threat profile.

Priority Support (24-48hr)

Direct analyst access for follow-up questions on your findings within 24-48 hours of delivery.

Who The Lockdown is for

  • Your current or former employer has been breached and you don’t know what was taken or where it ended up
  • You reuse passwords across personal and work accounts — and suspect that one of them may already be compromised
  • You saw your Mirror results and want to go deeper — into what’s circulating in credential markets and dark forums
  • You suspect your accounts may be compromised but haven’t been able to confirm it through normal channels

How Account Takeover Actually Works

Most account takeover doesn't happen through brute-force password guessing. It happens because the credential — the exact email and password combination — was already stolen, and is circulating in a market where buyers pay as little as $2 per log.

The mechanism has three entry points.

Credential replay. A stealer log or breach database contains your email and the password you used when that service was compromised. If you reused that password anywhere else — which SpyCloud's 2026 analysis puts at 51% of accounts — the attacker doesn't guess. They walk in. The login looks legitimate because it is a legitimate credential. No anomalous behaviour to flag.

Session cookie theft. Modern infostealers harvest more than passwords. They copy session cookies — the tokens a browser holds to keep you logged in after authentication. A stolen session cookie doesn't need your password. It doesn't need to pass your MFA. It presents as an already-authenticated session. Changing your password after an infection doesn't invalidate tokens copied before you knew you were compromised. The technical mechanics of how infostealers harvest these are covered in detail in How Infostealers Work in 2026.

The password reset chain. The third route is the most underestimated. Access to your email inbox — current or a previous one — gives access to every account that accepts a password reset via that address. The forgot-password flow hands back entry without requiring the original password. This matters particularly for old addresses: an inbox you abandoned may still be the registered address for banking portals, SaaS tools, or corporate systems from a previous employer. Whoever controls that inbox can reset their way into all of them.

A Lockdown investigation maps all three surfaces: which credentials are in circulation, whether session tokens from your accounts appear in stealer log indexes, and which email addresses in your history remain active reset routes for accounts you may have forgotten you own.

Ready to Secure Your Digital Accounts?

Most breaches succeed not because of sophisticated hacking, but because of weak account security. The Lockdown helps you implement bank-grade protection across your entire digital life.

Credential-based attacks account for over 80% of breaches. Knowing what’s already leaked — and locking it down — costs less than the first fraudulent transaction.

Lockdown FAQs

The Mirror tells you what’s publicly visible and what’s been exposed in breaches. The Lockdown goes one layer deeper — into what’s actively circulating in corporate data dumps, credential markets, and closed forums. It also assesses which accounts are at realistic takeover risk based on what was found, and provides personalised security recommendations tied to those findings.

Recommendations are specific to what we found — not a generic checklist. If we found a plaintext password in a corporate dump, we tell you which accounts to rotate and what password manager to use. If we found your email in a credential market, we tell you which services are at risk and how to lock them down. Everything is tied to actual findings.

Delivery is typically within 5 business days. The investigation includes all Mirror-scope work plus the deeper credential and forum search layers, so it takes a little longer to compile fully. Priority support (24–48hr response) is included throughout.

The most important first step is understanding what was actually exposed — not just the company’s notification, which describes what was in their breached system, not what’s circulating and being used. Rotate the passwords you know were included. Enable two-factor authentication on any account that shares those credentials. Beyond that, an investigation tells you what’s specifically circulating in credential markets and which of your accounts are at realistic risk — so you’re acting on evidence, not assumptions.

It depends on what was taken and where it’s ended up. An email address alone is low risk. A cracked password hash is higher. A full credential pair circulating in a credential market is immediately actionable for attackers. Most breaches don’t result in immediate fraud — they feed long-tail attacks that emerge months later. The question isn’t how serious the breach was. It’s what’s been done with your specific data since.

Account takeovers often begin quietly — credential testing, session hijacking, or a slow build-up of profile data for a targeted attack. Free tools like Have I Been Pwned check known public breach databases, but they don’t cover closed credential markets, corporate data dumps, or dark forum references. A Lockdown investigation checks all of these and tells you which accounts are at realistic risk based on what’s actually circulating — not just what’s been publicly disclosed.
