The URLLOGINPASS Leak Contains More Records Than the Population of Houston

HEROIC analysts documented a large stealer log file uploaded to Telegram in November 2025 simply labeled URLLOGINPASS. The file contained 2,454,089 records in URL:Login:Password format -- pairing each victim's exact website address with their email address and plaintext password. At nearly 2.5 million records, this is one of the largest files in this batch and one of the more significant Telegram credential uploads HEROIC has indexed from that period. The plaintext nature of every password in the file means there is zero barrier between download and attack for any criminal who obtains it.

Why a 2.4 Million Record Plaintext Credential File Is an Immediate Threat

In most data breaches, stolen passwords are protected by hashing -- a process that forces attackers to spend time and computing power cracking them. In the URLLOGINPASS file, every single password is stored in plaintext. There is nothing to crack. A criminal who downloads this file has 2.4 million ready-to-use username and password pairs, each tied to the specific URL where they work. Automated credential stuffing tools can process files like this at tens of thousends of login attempts per minute across dozens of websites simultaneously.

What the URLLOGINPASS Telegram Upload Exposed

• Email Addresses (2,454,089 unique accounts)
• Plaintext Passwords (no encryption, no hashing)
• URLs (the exact websites where each credential was captured)

Why 2.4 Million Stolen Credentials Enable Attacks Well Beyond Account Takeover

Files like URLLOGINPASS do not just enable account takeover. They are the raw material for a chain of downstream crimes. Once an attacker has access to a victim's email account using credentials from this file, they can reset passwords for banking, shopping, and social media accounts linked to that email. They can intercept two-factor authentication codes, read private communications, and impersonate the victim to their contacts. At 2.4 million records, the aggregate damage -- in finacial losses, identity theft, and personal distress -- is significant if victims do not act quickly to change their passwords.

How Telegram-Distributed Stealer Logs Like URLLOGINPASS Are Built and Spread

URLLOGINPASS-style files are the product of information-stealing malware deployed across thousands of individual devices. The malware reaches victims through phishing emails, pirated software downloads, fake browser extentions, and compromised game modification tools. Once installed, it quietly collects every saved browser credential alongside the URLs where they are used. This harvested data is aggregated by criminal operators into structured ULP files and published on Telegram channels where subscribers can download them. The November 2025 date reflects when the file was made public -- the underlying infections almost certainly occurred weeks or months earlier, giving the operators a period of exclusive access before publication.
