Researchers Link the ULP Abyss Cloud 3.950.059 Dump to 2 Million Stolen Credentials

HEROIC analysts identified one of the largest individual stealer log files in this batch: a Telegram upload in April 2026 labeled ULP Abyss Cloud 3.950.059 containing 2,029,254 records. Each entry in this file follows the URL:Login:Password format -- pairing a specific website address with the exact email and plaintext password used to log in there. The scale of this file is striking. Over two million people had their login credentials silently stolen and published in a single Telegram post. The Abyss Cloud infrastructure has demonstrated it operates at industrial scale, producing multi-million-record credential files on a regular basis.

Why 2 Million Plaintext Credentials in One File Is an Exceptional Threat

Most stealer log files contain tens of thousands of records. This file contains over two million. That means a single criminal actor downloading the ULP Abyss Cloud 3.950.059 file gains instant access to credentials for more than two million real online accounts across hundreds of different websites. With plaintext passwords and exact URLs already provided, automated credential stuffing attacks can begin within minutes of download. At this volume, the potential for identity theft, finacial fraud, and account takeover is not measured in individuals -- it is measured in communities.

What the ULP Abyss Cloud 3.950.059 Dump Exposed

• Email Addresses (over 2 million unique accounts)
• Plaintext Passwords (unencrypted, immediately usable)
• URLs (exact websites matched to each email and password pair)

Why the Abyss Cloud 3.950.059 Breach Has Long-Lasting Consequences

Files of this size do not simply disappear after the initial Telegram upload. A 2-million-record credential set is valuable enough to be resold repeatedly, incorporated into combolist databases, and used in credential stuffing campains for years. Every platform listed in this file -- banking apps, social media, email providers, e-commerce sites -- becomes a potential attack surface for every victim whose credentials appear. Because the passwords are plaintext, there is no time limit on their usability. As long as victims have not changed their passwords, every entry in this file remains a working attack vector.

How the Abyss Cloud Operation Assembles Multi-Million Record Credential Dumps

Building a file with over two million credentials requires systematic infrastructure. Abyss Cloud and similar operations deploy information-stealing malware at mass scale, infecting thousands of devices simultaneously through phishing campains, pirated software, fake game tools, and malicious browser extentions. Each infected device quietly sends back all of its saved browser credentials. These are aggregated, cleaned, formatted into ULP files, and uploaded to Telegram in numbered batches. The 3.950.059 designation likely reflects the cumulative record count across multiple uploads from the same operation. This is not a one-time incident -- it is an ongoing automated credential harvesting pipeline.
