9667 Records from 26.7 LOGS_CENTEER Leaked in Stealer Log Attack

On July 25, 2022, a Telegram user shared a stealer log file containing 9,667 stolen credential records. The file, labeled "26.7 LOGS_CENTEER," is one of several uploads from around the same time period that share this naming convention, suggesting an organized and recurring distribution effort. The credentials in this file are ready to use as-is, with plaintext passwords paired directly with email addresses and service URLs.

Why This Is Dangerous

Stealer logs represent one of the most actionable forms of stolen data an attacker can obtain. Unlike hashed password dumps that require cracking, these credentials are already in working form. Anyone who downloaded this file in 2022 could have started testing accounts within minutes of receiving it.

The fact that this leak is several years old does not reduce the risk to people who have not changed their passwords since then. Password reuse is extremely common, and credentials that were valid in mid-2022 are often still valid on the same accounts today. Attackers are well aware of this, and old stealer logs remain valuable commodities.

The Telegram distribution model means there is no way to know how many people have accessed this file since it was first shared. It could have been downloaded hundreds or thousands of times, each download representing another potential attacker with access to these credentials.

What Was Exposed

• Email addresses used to log in to compromised accounts
• Plaintext passwords captured live from infected devices
• URLs of websites and web applications accessed by victims
• API host addresses pulled from application sessions
• Browser-stored passwords harvested by the stealer malware
• Active login session data from the time of device infection
• Endpoint metadata linking credential records to specific devices

Why This Matters

This entry represents 9,667 individuals whose credentials were captured without their knowledge. Each record carries the potential for account takeover across any service where the victim used the same email and password combination. For people who reused credentials, the blast radius extends well beyond whatever site or app they were using when the infection occured.

For companies, the risk is just as real. If an employee's work email is in this dataset, an attacker could use those credentials to attempt access to corporate systems, cloud services, or internal tools. A single successful login from a stale credential can be the starting point for a much larger breach.

How Stealer Log Works

Infostealer malware typically arrives through phishing emails, malicious advertisements, or software packages that have been tampered with. Once running on a device, it scans for stored passwords in browsers and applications, reads cookies tied to active sessions, and logs any credentials the user types while it is active on the machine.

Everything collected is bundled into a structured log file and sent back to the attacker. These files are then distributed through Telegram channels, sold on dark web marketplaces, or given away as samples to attract buyers for larger datasets. The "LOGS_CENTEER" naming pattern seen across multiple uploads from this period indicates a coordinated operation with a consistent workflow for packaging and releasing stolen data.

Unlike a typical data breach where a company's server is compromised, stealer infections happen at the user level. There is no organization to notify you and no breach disclosure law that applies. Most victims never know their credentials were captured at all, which is why checking against known breach databases is so important.
