20,467 Credentials Leaked: The SunCloudNew Telegram Stealer Log

HEROIC's intelligence pipeline captured the SunCloudNew LogsFile.part2 dataset, a stealer log package uploaded to Telegram in November 2025 that exposed 20,467 records from infected US endpoints. The "1030 - 3850" range in the filename likely refers to a record batch or lot numbering scheme used by the operator to organize and distribute the collected data in segments. Each entry in the file includes an email address, a plaintext password, and the URL of the site from which the credentials were harvested.

At over 20,000 records, this is a substantial stealer log release. The combination of plaintext passwords and source URLs makes every record immediately usable for credential stuffing or direct account access attempts. Because the data was distributed via Telegram in late November 2025, it is among the more recent stealer log releases in HEROIC's database, and affected accounts are more likely to still be active and vulnerable to exploitation.

Why SunCloudNew 1030 - 3850 LogsFile.part2 uploaded by a Telegram User Credential Data Is Valuable to Attackers

Stealer logs like SunCloudNew LogsFile.part2 are particularly attractive to criminal actors because they eliminate the most time-consuming step in account takeover operations -- figuring out which credentials work where. With source URLs included alongside each email and plaintext password, attackers can target specific services directly rather than running broad stuffing campaigns. This enables highly efficient fraud: banking credentials are tested against the exact bank URL from the log, corporate login URLs are matched against enterprise targets, and e-commerce sites are hit with credentials harvested from the same storefront. Password reuse extends this further -- a single credential can unlock accounts across a dozen unrelated platforms. The November 2025 recency of this data increases the probability that passwords haven't yet been changed.

What Is a Stealer log and How Does It Work?

A stealer log originates from infostealer malware that silently infects a device and extracts browser-stored credentials, autofill data, and session tokens. The malware sends this data to an operator's infrastructure, where it is compiled into log files and then distributed -- typically through private Telegram channels. "SunCloudNew" appears to be a named collection or channel used by a specific operator, and the "LogsFile.part2" suffix indicates this is the second segment of a larger collection. The structured distribution model allows operators to sell or share credential packages to many buyers simultaenously. Victims have no reliable way of knowing their device was infected until account compromise occurs.
