Your Login Data May Be Exposed: 4M URL LOG PASS Leaked 1.3M Records

Your credentials could already be sitting in a file with an inflated name. In May 2025, HEROIC analysts examined a Telegram upload titled 4M URL LOG PASS, which its uploader labeled as containing 4 million records. HEROIC's verification found 1,319,334 actual email and plaintext password pairs, along with the URLs each was used on. The real number is significantly smaller than the file name suggests, and this article reports the verified count rather than the name's claim. Why This Combolist Is Dangerous: Even at the verified count of over 1.3 million, this remains a large file. Every credential is stored as plaintext, meaning an attacker can immediately test each pair against other websites without cracking any encryption. What Was Exposed: - Email addresses - Plaintext passwords - URLs tied to each login pair Why This Matters: At more than 1.3 million pairs, automated credential stuffing tools can churn through this entire file in a short period, testing logins against banking, retail, and social media sites at scale. If you reuse passwords, a file like this can turn one old, forgotten login into access to your more important accounts today. How a Combolist Like This Gets Assembled and Inflated: Sellers on Telegram often round up or exaggerate record counts to make a file sound more valuable, combining smaller batches from old breaches, phishing kits, and malware logs into one list. HEROIC verifies actual record counts rather than relying on file names or uploader claims, which is why the number reported here differs from the '4M' in the title. Check If You Are Affected: Use HEROIC's free breach scanner to check your email against more than 400 billion verified leaked records, including this one, and find out if your credentials need to be changed.
