InfernoLogsCloud Combo Breach: 715,411 Passwords Exposed

715,411 records, to be exact. That is the precise count HEROIC analysts logged from a combolist called FR COMBO FREE186, distributed by a Telegram seller operating under the name InfernoLogsCloud in October 2025. The file pairs email addresses with plaintext passwords and the URLs where each login was captured, harvested from infected devices rather than a single hacked company.

Why This Is Dangerous

A combolist this size gives attackers a ready supply of working logins to test automatically, at scale, with minimal effort. Each entry links an email to a password and the exact site it opens, meaning there is no guesswork involved. The FR label suggests a concentration of French-language or France-linked accounts, but stealer logs like this frequently include victims well beyond any single country.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each login

Why This Matters

With over 700,000 credential pairs in one file, this combolist is a prime candidate for large-scale credential stuffing campaigns. Attackers run automated scripts that test each email and password against banking portals, email providers, and online retailers. Because password reuse remains common, a single match can lead directly to account takeover, identity theft, or financial fraud.

How Stealer Logs and Combolists Work

Stealer malware quietly infects devices through fake downloads or cracked software, then extracts saved browser passwords and autofill data. Sellers like InfernoLogsCloud compile these individual logs into combolists, giant text files organized and labeled for distribution, then release them for free or for sale on Telegram to attract buyers and build a reputaton in underground marketplaces.

Check If You Are Affected

With more than 700,000 records involved, the odds that your information is included are worth taking seriously. HEROIC's free breach scanner checks your email against a database of over 400 billion exposed records, so you can confirm your exposure and update any at-risk passwords right away.
