9878 Records from 26.7 LOGS_CENTEER Leaked in Stealer Log Attack

Back in July 2022, a file called "26.7 LOGS_CENTEER" was uploaded to a public Telegram channel, containing 9,878 stolen credential records harvested from infected devices. Although this leak is a few years old, credentials from stealer log dumps like this one continue to circulate and get incorporated into combo lists used in active attacks today. If your accounts have not been audited since 2022, this is worth taking seriously.

Why This Is Dangerous

Stealer log files are not guesses or brute-forced passwords. They are working credentials captured live from infected machines, meaning they were valid at the time of collection. Even years after a breach like this occured, many of these passwords are still active because people rarely change credentials unless forced to.

The data in this file includes plaintext passwords, which means there is no technical barrier between an attacker and account access. No decryption, no cracking, no reverse engineering needed. The credentials are ready to use as-is in any login form.

Leaks from Telegram channels like this are frequently recycled into newer credential databases. A record from July 2022 may have already been tested against dozens of platforms and could be surfacing again in a fresh attack campaign right now.

What Was Exposed

• Email addresses connected to compromised user accounts
• Plaintext passwords taken from active device sessions
• URLs for websites and services the victims were accessing
• API host addresses captured from application connections
• Browser-stored login credentials collected by the malware
• Session tokens and authentication data from the infected endpoints
• Device-level identifiers linking credentials to specific machines

Why This Matters

With 9,878 records, this is a targeted and dense dataset. The naming convention "26.7" likely refers to the date of compilation, suggesting a deliberate, organized effort to package and distribute these logs on a specific schedule. That kind of structure indicates a threat actor who is methodical, not opportunistic.

For individuals, any account tied to an email in this file deserves immediate attention, particularly if that password has been reused elsewhere. For businesses, an employee whose credentials appear here could have inadvertently opened the door to internal systems, especially if multi-factor authentication is not enforced.

How Stealer Log Works

Infostealer malware spreads through phishing emails, malicious software cracks, and fake browser extensions. Once installed on a device, it silently harvests everything stored in the browser, including saved passwords, cookies, and any credentials typed into login forms while the malware is active.

The collected data gets packaged into a structured log file and sent to the attacker, either through a command-and-control server or directly to a Telegram channel. From there, the logs are sold, traded, or released publicly. The "LOGS_CENTEER" naming pattern appears in multiple uploads, suggesting this may be part of a recurring distribution operation rather than a one-time event.

What seperates stealer logs from typical database breaches is that the infection happens on the user's own device. The compromised data reflects real, active sessions, not old records sitting in a database. That makes the credentials significantly more likely to still be valid when they are eventually put to use.

Check If You Were Affected

You can check whether your email appears in this or thousands of other known credential leaks using HEROIC's free breach checker at heroic.com. Even if you beleive your passwords are secure, a quick check can confirm whether your credentials have been exposed and help you take the right steps before an attacker does.
