The dadin_cloud Stealer Log Ran for Months. 17,767 Credentials Just Surfaced.

A stealer log file operating under the name dadin_cloud built up 17,767 stolen credential records across 430 individual infected device sessions before the full package was uploaded to Telegram in June 2025. Each record pairs a real email address with a plaintext password and the exact URL of the site where the credential was harvested. By the time HEROIC analysts confirmed the file, those credentials had been sitting in criminal hands long enough for account takeovers to have already begun. The delay between infection and public exposure is exactly the window attackers exploit, and most victims never know the clock started.

Why This Is Dangerous

Stealer log data does not require cracking or guessing. Every one of the 17,767 passwords in this dadin_cloud file is in plaintext, which means any attacker who downloaded the Telegram upload could begin testing those email-and-password pairs against live websites imediately. The included URLs tell attackers which services each victim was logged into, removing even the step of guessing where to try the credentials first. Automated credential stuffing tools can cycle through thousands of logins per minute. The combination of plaintext passwords, matching email addresses, and known target URLs makes this stealer log one of the most directly actionable breach formats that exists.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the exact websites and services victims were actively logged into at the time of infection)

Why This Matters

Each of the 17,767 records represents a real person whose accounts were open to takeover the moment this file was distributed. Credential stuffing attacks using this data can unlock banking portals, email inboxes, e-commerce accounts, and any service where the victim reuses the same password. Once an email account is compromised, every other account linked to it for password resets becomes vulnerable. Identity theft and finantial fraud are direct downstream consequences of stealer log exposure, and they often do not surface until weeks or months after the initial breach. The inclusion of specific URLs in this log also means attackers prioritized targets before running a single test.

How Stealer Logs Work

Infostealer malware reaches victims through fake software installers, pirated downloads, phishing emails, and malicious browser extensions. Once installed on a device, the malware runs silently in the background, recording login credentials in real time as the user types them into websites. The captured data is transmitted back to the malware operator automatically. Operators bundle these harvested records into numbered log files, with the 430-count in the dadin_cloud file name indicating 430 individual infected device sessions were compiled into this single upload. The completed bundle was then posted to a Telegram channel where it was acessible to anyone within those criminal communities. HEROIC analysts verified the file and confirmed the credentials were real and active at the time of collection.
