One Telegram Upload. Three Data Types. The 32_Boss Stealer Log Had 1,080 Records.

In June 2023, HEROIC's threat intelligence team identified a stealer log file uploaded by a Telegram user operating under the alias 32_Boss. The dataset exposed 1,080 records containing endpoint credentials, email addresses, API host information, and plaintext passwords. This type of leak is a hallmark of modern infostealer malware campaigns, where infected devices silently harvest saved credentials before transmitting them to attacker-controlled channels.

Why This Is Dangerous

When attackers obtain stealer log data, they immediatly put it to work. The combination of email addresses, plaintext passwords, and URLs gives threat actors a precise roadmap to targeted accounts. Unlike hashed credentials that require cracking, plaintext passwords can be used directly in automated login scripts. Attackers will test these credentials across banking portals, email providers, social media platforms, and corporate VPNs within hours of obtaining the data.

What Was Exposed

The 32_Boss Telegram stealer log contained the following data types for each of the 1,080 affected records:

• Email Addresses
• Plaintext Passwords
• URLs (endpoint and API host addresses)

Why This Matters

The exposure of plaintext passwords alongside associated URLs creates a direct pathway to credential stuffing attacks. Cybercriminals use automated tools to test stolen username and password pairs across hundreds of websites simultaneously. Given that a large portion of users recieve little warning when their credentials are compromised, many victims remain unaware their accounts are at risk for months or even years. This enables account takeover, identity theft, financial fraud, and unauthorized access to corporate systems.

How Stealer Log Breaches Work

A stealer log breach originates from infostealer malware installed on a victim's device, often through phishing emails, malicious downloads, or compromised software. Once installed, the malware quietly scans the device for saved browser credentials, autofill data, session cookies, and stored passwords. The collected data is then packaged into log files and transmitted to a command-and-control server or posted directly to dark web forums and Telegram channels. The entire process can occure in minutes, and victims typically have no idea their credentials have been stolen until the data surfaces publicly.
