The AIRBENDER PREMIUM CLOUD Data Quietly Appeared on Telegram Last December

HEROIC analysts found the AIRBENDER PREMIUM CLOUD stealer log on December 24, 2023, after it appeared on a public Telegram channel shared by an anonymous user. The file contained 7,341 records harvested from compromised endpoint devices. Each record included an email address, a plaintext password, and a URL pointing to the service or application where the credentials were used. The log format matched patterns produced by well-known infostealer malware families, confirming this was a device-level compromise rather than a server-side breach. HEROIC verified the records and added the dataset to its breach monitoring database.

Why This Is Dangerous

Stealer logs with plaintext passwords require no additional work from attackers. Every record in this file is immediately actionable: the email is the username, the password is ready to use, and the URL tells the attacker exactly where to try it first. With 7,341 records available on a public Telegram channel, this data was accessible to any threat actor watching that channel. Victims face account takeover risk not just on the service listed in the URL, but on any other site where they used the same password, which for most people is many sites.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs associated with the compromised credentials

Why This Matters

The consequences of stealer log exposure extend well beyond the original breach. Attackers use these credential sets for credential stuffing, running automated login attempts across banking sites, email providers, e-commerce platforms, and corporate VPNs. Successful logins lead to account takeovers, which can result in identity theft, unauthorized financial transactions, and access to sensitive personal or business data. People who reuse passwords are at the highest risk. Even a single compromised account can expose connected services through password reset emails or shared authentication tokens. It is definitaly not a minor inconvenience when attackers get in through an old reused password.

How Stealer Logs Work

Infostealer malware is installed on a victim's device without their knowledge, often through a phishing link, a fake software download, or a malicious browser extension. Once active, it monitors the device for credential entry points: web browser saved passwords, autofill fields, session cookies, and application login prompts. As the user logs in to websites and services, the malware captures the email and password in real time before any encryption is applied. These harvested credentials are bundled into a structured log file and uploaded to an attacker-controlled server or posted directly to a Telegram channel. The process is largely automated, meaning thousands of devices can be harvested simultaneously by a single operator running the campaign.
