Inside Redline Cl0ud4 Jul 13 Logs: 2,919,449 Passwords Harvested

HEROIC detected a massive stealer log collection labeled Redline Cl0ud4 ULPP (dated July 13, 2026) being distributed through Telegram channels. This single dump contains 2,919,449 compromised credential records captured by RedLine infostealer malware. With all passwords stored in plaintext, this represents one of the largest single-day credential exposures HEROIC has tracked.

Nearly 3 Million Unprotected Passwords

The scale of this exposure is severe. Each of the 2,919,449 passwords exists in its original, unmodified form — no hashing, no salting, no encryption of any kind. Attackers can query the data for specific email domains, service URLs, or individual addresses and retrieve working credentials within seconds. The plaintext format transforms this dataset into an instant-access credential warehouse.

What Was Exposed

• Email Addresses — nearly 3 million account identifiers exposed to exploitation and phishing
• Plaintext Passwords — stored in their original form and immediately usable for account takeover
• URLs — providing a comprehensive map of every compromised website and login portal

Credential Stuffing at an Unprecedented Volume

Nearly 3 million credential pairs represent a massive ammunition supply for credential stuffing operations. Attackers deploy distributed bot networks to test these combinations across every major service category — financial platforms, email providers, government portals, healthcare systems, and enterprise SaaS applications. The volume ensures that even with low individual success rates, the total number of compromised accounts reaches into the tens or hundreds of thousands.

RedLine Stealer: Technical Profile of the Threat

RedLine remains one of the most technically capable and widely deployed infostealer malware families. Sold as malware-as-a-service on underground forums, it provides attackers with a turnkey credential harvesting platform. The malware targets all Chromium-based and Gecko-based browsers, extracting passwords from local storage databases. It also captures session cookies that can bypass multi-factor authentication, steals cryptocurrency wallet files and keys, and collects detailed system fingerprints. Stolen data is automatically exfiltrated to attacker-controlled servers and organized into the structured log format seen in this dump.

Check If Your Credentials Were Exposed

At nearly 3 million records, this is among the largest stealer log dumps in circulation. HEROIC's breach monitoring platform indexes over 400 billion compromised records from data breaches and stealer logs across the globe. Search your email address or domain with HEROIC's breach scanner to see if your credentials have been exposed in this or any other known breach. If found, change your passwords immediately and enable multi-factor authentication on all critical accounts.
