In 2025, law enforcement keeps knocking criminal sites offline, yet the stolen password market keeps roaring back. Recent reporting tallies more than 53.3 billion distinct identity records in circulation. Criminal groups trade bundles of usernames, stolen passwords, and session cookies at speed, which means a single infected laptop can put an entire organization at risk. Utah businesses from the Wasatch Front to St. George face the same threats as national brands, and 1Wire is tracking these trends every day so local teams can stay ahead.
In this article, we explain the stolen password market and show you how to verify if you are compromised in one minute.
Key Takeaways
-
Infostealer logs fuel the modern stolen password market.
-
Browser-saved passwords are prime targets—use a password manager.
-
Quick wins: HIBP check, browser audit, rotate compromised creds, enable 2FA/passkeys.
-
If you used LastPass, verify your PBKDF2 iterations, strengthen your master password, and keep MFA on.
Why this matters right now
Law enforcement takedowns may slow criminal marketplaces for a short time, but credential shops and stealer log markets quickly return and continue selling your stolen password. These sites let buyers search by company domain and purchase “logs” that bundle usernames, passwords, and active session cookies from infected devices. That combination enables immediate impersonation, bypasses normal logins until sessions are invalidated, and fuels follow-on fraud and ransomware. For Utah organizations, this churn means the risk never truly pauses; routine exposure checks, fast password rotation, and 2FA on key accounts make the biggest difference.
The stolen-password market, in plain English
What’s being sold. Criminal marketplaces sell bundled infostealer logs harvested from infected devices. Listings are typically searchable by company domain and often include:
-
Usernames and passwords for websites and apps
-
Session cookies or tokens that enable access without a password until they expire
-
Autofill data such as names, addresses, and phone numbers
-
Email credentials and OAuth tokens used to pivot into other services
-
Payment and wallet details like stored card metadata or crypto wallet info
-
Saved browser data including form fills and sometimes bookmarks
-
System and device fingerprints such as IP address and user agent that help attackers imitate the victim
Why it works. Cheap malware-as-a-service kits make it easy for criminals to run infostealer campaigns, while malvertising and realistic phishing pages drive victims to trojaned installers. These tools pull browser-saved passwords, session cookies, and autofill data in seconds, and a single log can include dozens of active credentials plus device fingerprints that help attackers blend in.
What it costs. Pricing tracks value and freshness. Bulk consumer PII is inexpensive and often sold in large dumps, while credential packs for banking, crypto exchanges, payroll portals, or enterprise SaaS/admin access command significantly higher prices and are sometimes priced per account. Rates change with demand, recency, and whether valid session cookies or device fingerprints are included. Most markets operate like storefronts with search by domain, seller reputations, and recurring “restock” cycles. (Context, not endorsement.)
How passwords are harvested (and why “I’m careful” isn’t enough)
Infostealer malware is malicious software that quietly installs on a device and copies whatever the browser has saved. Examples include RedLine, Raccoon, Vidar, and Lumma. It looks for stored usernames, passwords, and session cookies, then sends that data back to the attacker. The stolen bundle is packaged as a “log,” which is a simple file that lists the accounts, websites, and tokens pulled from that device. Criminals then list these logs for sale in credential shops where buyers can search by company name or website.
Common infection paths (real-world examples):
-
Fake installers / cracked software bundles.
-
Poisoned search ads (malvertising) that lead to trojanized downloads.
-
Email attachments and drive-by downloads on compromised sites.
Ransomware crews and other actors increasingly pivot off stolen SaaS credentials found in these logs.
Case study: What the LastPass breach taught everyone (even if you never used it)
What happened. In August 2022 attackers breached parts of LastPass. Months later they compromised a DevOps engineer’s home computer and used that access to reach company cloud storage. From there they copied encrypted vault copies and also took unencrypted metadata such as website URLs, account names, and other vault details. The passwords inside the vaults remained encrypted, but the metadata could still help attackers target users with convincing phishing or identify high value accounts.
Why that matters:
-
Use a strong, unique master password and a high PBKDF2 iteration setting. PBKDF2 is the process that deliberately slows down password guessing by hashing your master password many times. A higher number of iterations makes each guess take longer, which makes cracking your encrypted vault far harder. Older accounts may still have a lower default, so check your setting and raise it before you rotate passwords.
-
Unencrypted metadata (like URLs) still helps attackers target you.
Takeaway. Password managers are safer than reusing the same password. To stay protected, use a strong and unique master password, set a high PBKDF2 iteration count if your manager allows it, turn on 2FA, and keep your devices clean and up to date.
Verify if your email/password is already exposed (60-second checks)
A) Check your email in breaches
Use Have I Been Pwned and enable notifications that alert you on stolen passwords. (CTA button: “Check my email”).
B) Check if a password has appeared in leaks—privately
HIBP Pwned Passwords uses k-anonymity (only the first 5 hash characters are sent), so your actual password isn’t revealed. Never test an active master password.
C) Use what you already have
- Google Password Checkup flags compromised/reused/weak passwords.
- Microsoft Edge Password Monitor alerts when saved creds appear in leak datasets.
- Apple Security Recommendations warn on reused/weak and “data leak” passwords.
Do this now:
- Run HIBP on your email → change any listed site passwords.
- Test an old password with HIBP Passwords; if “pwned,” retire it everywhere.
- Run your browser’s password audit; rotate anything marked “compromised.”
Stop the bleed: harden your password strategy in 3 moves
- Use a password manager (and harden it): strong unique master (high-entropy phrase), increase KDF iterations if your tool allows, enable 2FA on the vault, keep endpoints clean.
- Kill risky browser-saved passwords—infostealers target browser stores first; move them into your manager.
- Rotate “crown jewel” accounts first (email, bank, payroll, cloud admin). Attackers monetize those quickly once logs leak.
2FA (and passkeys): your safety net when passwords leak
Why it works. Even if your password shows up in a stolen password log, a second factor stops most takeovers. Enable MFA/2FA everywhere you can.
Phishing-resistant options (best): Passkeys / FIDO2 / WebAuthn.
Practical picks by risk:
- Best: device-bound passkeys (security keys or platform passkeys).
- Better: app-based TOTP codes.
- Avoid when possible: SMS (SIM-swap risk).
- Using push prompts? Turn on number-matching to curb push-bombing.
What to do if you find your creds for sale or exposed
Stay calm. Take the following steps to secure your accounts.
-
Change that password everywhere it’s reused (your manager’s “reused” report helps).
-
Invalidate open sessions (log out on all devices) and rotate app passwords/API keys.
-
Check inbox filters/forwarders and recovery methods (attackers plant persistence).
-
Watch for follow-on scams (invoice fraud, crypto drains, account takeovers).
-
If financial data is exposed, consider identity monitoring or a credit freeze.

FAQs
Is it safe to use a password manager after the LastPass breach?
Yes—reusing passwords is far riskier. Use a reputable manager, set a strong unique master password, ensure high PBKDF2 iterations (or modern memory-hard KDFs where available), and enable 2FA on your vault.
What’s the fastest way to see if I’m exposed?
Run Have I Been Pwned for your email, then your browser’s password audit; rotate anything flagged as compromised.
Are passkeys really better than passwords + 2FA?
Yes—passkeys are phishing-resistant by design and align with modern guidance. Where passkeys aren’t available, use app-based TOTP and turn on number-matching for push MFA.
Why avoid storing passwords in the browser?
Infostealers target browser stores first and exfiltrate saved passwords and cookies. A dedicated password manager with MFA is safer.
I saw my password in a leak—now what?
Change it everywhere it’s reused, log out of all sessions, rotate app passwords/API keys, and enable 2FA. Watch for suspicious inbox forwarding rules.
