Stealer Check Find out if an infostealer has your logins.
Breach lists tell you what leaked. Stealer Check tells you what malware took from your device: which sites had saved logins, and when. Free, and the result goes only to your inbox.

Not a breach. A copy of your browser.
A data breach means a company you use lost a copy of its customer list, usually with hashed passwords, often years ago. Change that one password and you're done.
A stealer log is different. Infostealer malware ran on your own computer and copied everything the browser had saved: every site, every password, every signed-in session. Changing one password doesn't fix that. Cleaning the device, then signing out everywhere, does.
Have I Been Pwned is the place to check data breaches. Stealer Check looks at what malware took from an infected device, and tells you what to do about it. Use both.
What are infostealers?Am I affected by an infostealer?
Most victims never notice the infection. These are the signs people report before they check, and none of them is proof either way.
Accounts signed in from places you've never been
Security alerts for Google, Microsoft, Steam, Discord or PayPal logins from another country, often with no password-reset email, because a stolen cookie didn't need one.
Passwords changed that you didn't change
Locked out of email, gaming or crypto accounts, or recovery details swapped for ones you don't recognise.
You ran something you now doubt
Cracked software, a game cheat, a mod, a fake installer from a search ad, or a file a stranger sent you on Discord or Telegram.
Friends get messages from you
Spam, crypto offers or odd links sent from your social or chat accounts while you were doing nothing.
A clean antivirus scan proves nothing
Most infostealers run once, upload the browser's saved data in seconds, then delete themselves. The log is what remains, and it's the log we search.
No sign at all
The common case. The stolen credentials sit in a log for months before anyone uses them. A check is the only way to know.
How it works
Three steps, and the only person who sees the result is you.
Enter your email
Any address: personal or work. This page never says whether it was found.
Read the result in your inbox
We email it to that address and nowhere else. Only someone who can open the inbox sees it.
Fix it, in order
Clean the device first, then sign out everywhere, then change passwords. The email walks you through it.
What you'll see
Sites with saved logins
Every service the malware found saved in your browser for this address.
When it reached us
The date each stealer log was added to our data, so you can match it to when something went wrong.
How many logins
How many saved logins each log holds for this address, so you know the size of the clean-up.
What to do, in order
Clean the device, sign out everywhere, then change passwords. The email walks you through it.
Passwords are never in the email, masked or otherwise. Change the password for every site listed, from a clean device.
If we find you, do this
The order matters. Resetting passwords on a still-infected machine just hands the attacker the new ones.
Clean the device
Run a full scan with a reputable antivirus, or back up and reinstall. Remove cracked software and game cheats: they're the usual way in.
Sign out everywhere
Google, Microsoft, Apple, Facebook, Discord, Steam and your bank all have a "sign out of all devices" option. Stolen cookies bypass passwords and 2FA, so this comes before any reset.
Change passwords, from a clean device
Email first, then every service listed, then anything that shared a password with them.
Turn on 2FA and check recovery
Prefer passkeys or an authenticator app. Check email forwarding rules, recovery addresses and connected apps for anything you didn't add.
Was it a work device?
If the infected machine had work logins on it, your employer's accounts are exposed too. Tell your IT team, or check your whole company's domain for free. It takes one work email and emails back an exposure report.
Keep watching
New stealer logs reach us every day. Your result email has a link to turn on free alerts: we'll email that address whenever new data containing it arrives. Every alert has a one-click unsubscribe, and once a year we'll ask if you still want them.
Stealer Check: common questions
What people ask before they check.
What is an infostealer?
Infostealer (or info stealer) malware is a program that runs on your computer, copies everything the browser has saved (passwords, session cookies, autofill, crypto wallets) and uploads it to the attacker. The bundle it uploads is called a stealer log. Logs are sold and traded in bulk, which is how your logins end up in criminal hands months after the infection.
How do I check if I've been infected by an infostealer?
Enter your email address above. We search over 200 billion credentials collected from infostealer logs for that address and email you the result: when each log reached us, which sites had a saved login for it, and what to do. If nothing is found we tell you that too. It's free and takes a few minutes.
Is Stealer Check really free?
Yes. Checking an email address, receiving the result and getting alerts about new logs all cost nothing. There's no card, no trial and no sales call. DarkStrata is paid for by businesses that monitor their whole domain.
My antivirus is clean. Can I still be in a stealer log?
Yes. Most infostealers run once, upload the browser's saved data within seconds, then remove themselves, so a later scan finds nothing. The log they uploaded is permanent. Checking the logs is the only way to know whether your data was taken.
Can I check someone else's email address?
No. Results only ever go to the address itself, by email. Typing in someone else's address tells you nothing and sends them a confirmation link. If you're worried about a friend or family member, send them this page.
If nothing is found, am I safe?
A clean result means we haven't seen your address in the stealer logs we hold. It doesn't mean it has never been taken. Turn on alerts from the result email, and if your device behaves oddly, follow the infection guide anyway.
Can Stealer Check alert me if my email turns up in a new infostealer log?
Yes, for free. The result email has a link to turn on alerts. Each time we add new stealer logs, we check them for your address and email you which sites had a saved login and when the data reached us. Never the passwords. Every alert has a one-click unsubscribe.
Why do you email the result instead of showing it?
Because a stealer log is far more sensitive than a breach record: it shows which sites you use and your usernames. Sending it to the address itself means only someone who can open that inbox ever sees it.
How is this different from Have I Been Pwned?
Have I Been Pwned is the best place to check data breaches, and it shows results on the page. Stealer Check is about infostealer logs: what malware copied from your own device, including saved passwords and session cookies. Because that detail is private, we verify you first and show the fix steps alongside it.
Will you show me my passwords?
No, never. The result lists the sites and dates, not the passwords. Change the password for every site listed, from a clean device, not just the one you think was taken.
What do you store about me?
The address you asked us to check, for 30 days. If you turn on alerts, we keep the address until you unsubscribe (one click in any alert) and delete it within 30 days after that, and we stop alerts if you don't confirm once a year. The stolen data itself was collected from criminal sources and is held to detect and respond to compromise, as set out in our privacy policy.
Check your own email. Free.
Takes a minute. The result goes to your inbox and nowhere else.
