Telegram Stealer Log Exposed 17,349 Records in December 2025

In December 2025, HEROIC's threat intelligence team discovered a stealer log file quietly posted to Telegram that exposed 17,349 records from privatArtHouse CLoud Bonus.part02. The leak bundled together email addresses, plaintext passwords, and URLs -- the kind of combination that gives attackers an instant road map into victims' digital lives. What makes this one particularly concerning is that the passwords were stored and exfiltrated in plain text, meaning no cracking was required at all.

Why This Is Dangerous

Stealer logs are not your typical database dump. They are harvested in real time from infected devices, capturing credentials as users type them. When plaintext passwords are bundled with matching email addresses and the specific URLs where those credentials work, attackers can skip the guesswork entirely. They know exactly where to log in. For victims, this means every account tied to that email address is at risk -- not just the one that was compromised first. Credential stuffing attacks can ripple outward to banking, healthcare, and corporate logins within hours of a log hitting the dark web.

Records Leaked in the privatArtHouse CLoud Bonus.part02 Breach

• Email Addresses
• Plaintext Passwords
• URLs (the specific sites where credentials were captured)

A total of 17,349 unique records were exposed in this breach, all originating from a stealer log uploaded by an anonomous Telegram user in December 2025.

What Criminals Can Do With privatArtHouse CLoud Bonus.part02 Data

With email addresses paired to plaintext passwords and target URLs, cybercriminals have everything needed for immediate account takover. Common attack paths include:

• Direct account access: Log straight into accounts using the captured credentials without any additional effort.
• Credential stuffing: Automate login attempts across hundreds of other popular services using the same email and password combination.
• Phishing follow-up: Use the victim's email account to send convincing phishing messages to their contacts.
• Financial fraud: Pivot from compromised accounts to linked payment methods, online banking, or stored credit cards.
• Corporate infiltration: If the stolen credentials belong to an employee, attackers may gain access to enterprise systems, VPNs, or internal tools.

Stealer Log Breaches: A Primer

Unlike traditional data breaches that target a single company's database, stealer log breaches are the result of malware -- typically infostealer trojans like Redline, Vidar, or Raccoon -- installed on an individual's device. The malware silently harvests stored credentials, browser cookies, autofill data, and session tokens as the user goes about their day. The collected data is then bundled into a "log" and sold or shared across dark web forums and encrypted messaging platforms like Telegram. Because these logs aggregate data from many different sites and services, a single log file can expose credentials for dozens of accounts per victim. The privatArtHouse CLoud Bonus.part02 log is a textbook example of this attack pattern.
