How Malware Led to 3,371 Stolen Logins in the SunCloudNew Dump

HEROIC discovered a stealer log file labeled SunCloudNew 1260 - 5000 LogsFile.part2 being distributed through Telegram. The archive contains 3,371 records stolen from infected devices, with each entry including an email address, a plaintext password, and the URL of the service where the credentials were saved. This data represents the output of an active infostealer malware operation.

The Danger of Passwords Stored in Plain Text

None of the 3,371 passwords in this SunCloudNew dump have been encrypted or hashed. They sit in the file as ordinary readable text, meaning anyone with a copy can log into affected accounts without needing any cracking software or technical knowledge. From the moment this file was shared, every credential inside it became immediately exploitable.

What Was Exposed

• Email Addresses — personal identifiers tying victims to accounts across the web
• Plaintext Passwords — unprotected login credentials in human-readable form
• URLs — the specific websites and applications where each password was stored

From One Password to Total Account Compromise

Credential stuffing turns a single stolen password into a weapon against every account that shares it. Attackers load these 3,371 email-password pairs into automated tools that hammer login pages across banking, email, retail, and social media platforms. The widespread habit of password reuse means that victims often lose access to multiple services from a single compromised entry in this SunCloudNew file.

The Infostealer Infection Chain

Every record in this dump tells the same story: a device was infected with infostealer malware. These programs — variants like RedLine, Raccoon, or Mystic Stealer — spread through fake software downloads, phishing attachments, and compromised websites. Once on a system, they silently scrape the browser’s password manager, capture session cookies, and record autofill data. The stolen information is then packaged into log files and funneled to criminal operators for resale or public distribution.
