The Blueyonder.com Log Contains Exactly 13,224 Stolen Passwords

HEROIC analysts found a stealer log tied to blueyonder.com that a Telegram user uploaded on 10 June 2026. The file contains exactly 13,224 records, each one an email address paired with a plaintext password and the URL of the login page that password was used on.

Why This Is Dangerous

This exposure did not come from a breach of blueyonder.com's own systems. It came from infostealer malware running on infected devices, quietly copying login details as people used them. Because the passwords in this file are stored in plaintext, an attacker can read every one of the 13,224 entries instantly, with no cracking required. The URL tied to each record tells an attacker exactly which login page a stolen password belongs to.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of stolen credentials

Why This Matters

With over 13,000 records in one file, this is a sizeable stealer log, and the risk grows with the number of people affected. Attackers take stolen credentials like these and test them against banking, email, and shopping accounts through credential stuffing, betting that people reused a password. Every successful match is a potential account takeover, which can quickly escalate into identity theft or financial fraud.

How Stealer Logs Work

Infostealer malware infects a device through a malicious download, phishing link, or infected attachment, then silently copies saved passwords, autofill data, and session cookies from the browser. That stolen information is bundled into a log file and sent to the attacker, often within hours of infection. Logs like this one are then sold or freely shared on Telegram, which is exactly how this blueyonder.com related file ended up circulating.
