Researchers Link ‘Redline Cloud ulpss 24’ to 2.5 Million Stolen Logins

In July 2026, HEROIC analysts identified a large stealer log collection labeled Redline Cloud ulpss 24 circulating on Telegram. The file contains 2,540,556 records of email addresses, plaintext passwords, and login URLs, consistent with logs harvested by Redline, one of the most widely used password-stealing malware families. Why This Is Dangerous: Redline malware infects a computer and copies every saved password, browser cookie, and autofill entry it can find, then sends that data back to whoever controls the malware. Unlike a typical database leak, this means the passwords in this file were taken directly from victims' own devices, often alongside their browsing history and other saved logins for the same accounts. What Was Exposed: - Email addresses - Plaintext passwords - URLs of the sites each login was used on Why This Matters: With over 2.5 million records, this file can power large scale credential stuffing campaigns, where attackers automatically test stolen logins across banking, email, and shopping sites. Because stealer logs often capture multiple accounts per infected device, a single victim's exposure here can extend to several of their online accounts at once. How Redline Stealer Logs Work: Redline is malware that spreads through phishing emails, cracked software, and fake downloads. Once installed, it silently harvests credentials stored in web browsers and applications, then uploads them to the attacker. Criminals collect these logs into large files like this one and label them by the tool and batch they came from before selling or sharing them further.
