The ‘Redline Cloud ulpss 17’ Dump: 3.9 Million Stolen Logins Found

In July 2026, HEROIC analysts identified a large stealer log file labeled Redline Cloud ulpss 17 circulating on Telegram, containing 3,876,033 records of email addresses, plaintext passwords, and login URLs, consistent with data harvested by Redline info-stealing malware. Why This Is Dangerous: Redline malware infects a device and quietly copies every password saved in the browser, along with autofill data and session details, then sends it all back to the attacker. With almost 3.9 million records in this batch, the file likely represents credentials pulled from a very large number of infected computers, not a single company's database. What Was Exposed: - Email addresses - Plaintext passwords - URLs of the sites each login was used on Why This Matters: A file of this size can be used to run large scale credential stuffing attacks against banks, email providers, and online retailers all at once. Because stealer logs often include several accounts per victim, one infected computer can expose an entire household or business's worth of logins. How Redline Stealer Logs Work: Redline spreads through phishing emails, pirated software, and fake downloads. Once installed, it harvests saved credentials and browser data from the infected device and uploads them to the attacker, who bundles the results into large files like this one, labeled by tool and batch for resale or further distribution.
