The 500PCS Free Logs: 5,248 Passwords Exposed. Yours Might Be One.

On June 4, 2023, a Telegram user uploaded a package labeled "500PCS - FREE LOGS" -- 500 individual infostealer log files handed out to anyone who wanted them, at no cost. Across all 500 files, the package contained 5,248 compromised records including email addresses, plaintext passwords, and the URLs of the services where each credential was originally stolen. The moment this package went live on Telegram, thousands of subcribers had access to 5,248 real passwords belonging to real people. HEROIC's DarkHive intelligence system captured and cataloged this upload as part of its continuous surveillance of dark web and Telegram credential markets.

Why This Is Dangerous

There is no barrier to entry with a free log drop. Anyone in the Telegram channel -- from a novice criminal with a credential stuffing script to a professional threat actor running automated attacks -- had immediate access to all 5,248 email and password pairs in this package. Unlike a paid breach sale where one buyer receives the data, a free drop means these 5,248 accounts were simultaneosly available to an unlimited number of attackers. Automated tools can test every combination against dozens of platforms in minutes. By the time most victims learn their password was stolen, it has already been tested thousands of times across the web.

What Was Exposed

• Email Addresses: 5,248 email addresses linked to device infections across 500 separate compromised sessions
• Plaintext Passwords: Unencrypted passwords captured live from browser storage by infostealer malware -- no cracking required
• URLs: The exact websites and services each stolen credential belongs to, letting attackers target high-value accounts directly

Why This Matters

Every password in this file was captured in plaintext from a real person's browser. It was then packaged with the URL of the site it belongs to -- meaning attackers didn't have to guess where to use it. If your password appeared in this file and you have not changed it, attackers may have already used it. Credential reuse is the primary amplifier here: if a password stolen from one site was also used for your email account, your bank, or your work login, a single record in this 5,248-entry file could cascade into a devasting account takeover across your entire digital life.

How Stealer Log Attacks Work

Infostealer malware spreads through phishing emails, pirated software, fake browser extensions, and malicious ads. Once it infects a device, it extracts every saved password from popular browsers including Chrome, Firefox, Edge, and Opera, along with session cookies and autofill data. A single infected device can surrender dozens of credential pairs across banking, email, shopping, and work platforms. The 500 devices compromised to produce this package each leaked an average of roughly ten credential pairs -- all captured in plaintext, all packaged into individual log files, and all released for free on Telegram the same day.

Check If You Are Affected

HEROIC's free breach scanner searches more than 400 billion exposed records, including stealer log free drops like this June 2023 package. If your email address appears in this collection or any other breach source in our database, you will receive an instant notification. The 5,248 passwords in this file were handed to attackers for free. Scan your email now and find out if your password is already in criminal hands -- before they use it.
