Search Your Email: The Binance_API_Keys Leak Exposed 4,068 Logins

On 19-Mar-2026, HEROIC analysts identified a file labeled "Binance_API_Keys" circulating after being uploaded by a Telegram user. Despite the name, the confirmed contents are 4,068 records pairing email addresses with plaintext passwords and associated login URLs, the same structure as a standard combolist rather than actual crypto exchange API credentials. Why This Is Dangerous Files that reference cryptocurrency exchanges by name are often used to bait buyers into paying for what looks like high-value data. Whether or not the file lives up to its title, the 4,068 email and password pairs inside it are still real, plaintext, and ready to use. Anyone whose login appears here and who reuses that password elsewhere can be logged into instantly by an attacker. What Was Exposed Email addresses Plaintext passwords Associated website URLs (the login pages tied to each credential) Why This Matters Credentials that surface near crypto-themed files are especially attractive to attackers because victims who use one password for a crypto exchange often reuse it for email, banking, or exchange-adjacent services. The email, password, and URL combinations in this file can be run through automated credential stuffing tools, putting anyone who reused a password at risk of account takeover, financial fraud, or identity theft. How This Combolist Was Packaged A combolist is a plain text file of email and password pairs, usually pulled from older breaches, phishing pages, or malware-infected devices and repackaged for resale or free distribution. Giving a file a name like "Binance_API_Keys" is a common tactic on Telegram to make a routine combolist sound more valuable than it is, since buyers pay a premium for anything tied to cryptocurrency accounts. The actual data inside frequently turns out to be ordinary login credentials, as it does here. Check If You Are Affected With 4,068 email and password pairs exposed in this leak, it is worth checking whether your information is included, especially if you use crypto exchanges or reuse passwords. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records and tells you immediately if you have been exposed.
