Redline Cl0ud4 Stealer Log Targets Users, Exposes 4,036 Logins

A stealer log going by the name Redline_Cl0ud4 surfaced on Telegram on 10-May-2026, and our team at HEROIC flagged it during routine dark web monitoring. The file, labeled "5.7K FRESH HOT HITS," might sound small compared to some of the mega-breaches we track, but it still contains 4,036 real records pulled straight off infected machines.

Why This Is Dangerous

Small does not mean harmless. Every single one of these 4,036 entries represents a real login that a real person typed into a real website, and it was recorded by malware sitting quietly in the background. The person who uploaded this file to a Telegram channel didn't hack a company database, they collected these credentials one infected device at a time, wich actually makes the data more dangerous in some ways because it often includes the exact password someone is currently using, not an old one from years ago.

What Was Exposed

• 4,036 total records
• Email Addresses
• Plaintext Passwords
• URLs of the sites the credentials belonged to

Why This Matters

Because the passwords in this file are stored in plaintext, anyone who gets a copy can use them imediately without needing to crack or decode anything. If any of these 4,036 people reused their password on another account, wich happens more often than most of us would like to admit, then that other account is at risk too. Attackers routinely take logs like this one and run them against banking sites, email providers, and social media platforms to see what else opens up.

How Stealer Logs Work

A stealer log is the output of infostealer malware, malicious software wich quietly installs itself on a victim's computer, often through a cracked game, a fake software download, or a malicious email attachment. Once it's running, it digs through the browser's saved password vault, autofill data, and sometimes even cookies, then packages everything up and sends it back to whoever is controlling the infection. That package is the "log," and it's exactly what got uploaded and shared here.

Check If You Are Affected

You don't have to just wonder if your information is sitting in a file like this one. HEROIC's free breach scanner checks your email against a database of more than 400 billion compromised records, including logs like Redline_Cl0ud4, so you can find out fast and take action before someone else does.
