Your 1.14 LOGS_CENTEER Data May Be at Risk: Here’s What You Need to Know

In January 2023, a Telegram user uploaded a stealer log file containing 29,118 compromised records, making it one of the larger credential dumps to surface through that channel during that period. The dataset, labeled "1.14 - LOGS_CENTEER," contained plaintext passwords, email addresses, and URLs harvested directly from infected devices. If your login details were captured before this log was assembled, they've been sitting in the hands of whoever grabbed it for well over two years now.

Why This Is Dangerous

With nearly 30,000 records exposed, the LOGS_CENTEER upload represents a meaningful pool of stolen credentials that attackers can work through at their leisure. Stealer logs like this one don't expire, and credentials recieved through these channels get tested against dozens of services through automated tools.

The plaintext nature of the passwords is what makes this particularly serious. There's no encryption to break and no hash to crack. The passwords are ready to use the moment someone opens the file, making every account in this dataset an immediate target for takeover attempts.

Because the log was shared on Telegram rather than a restricted dark web forum, the barrier to accessing this data was extremely low. It could have been downloaded by hundreds of different actors within hours of being posted.

What Was Exposed

• Email addresses tied to account logins
• Plaintext passwords captured from infected machines
• Website URLs and API endpoints visited or accessed
• Browser-stored credentials and autofill data
• Session tokens from active logins
• Application login paths and endpoint data
• Device and endpoint identifiers
• Potentially linked service credentials

Why This Matters

A breach of this size that has been sitting in circulation since early 2023 has had plenty of time to cause damage. Credential stuffing attacks using data this old are still very common because many people simply haven't changed their passwords since the data was first leaked, or beleive that older breaches no longer pose a risk.

The URLs included alongside the credentials can also reveal which platforms or services were being accessed, giving attackers useful context for crafting convincing phishing messages or prioritizing which accounts to target first.

How Stealer Log Works

Infostealer malware is typically delivered through phishing campaigns, fake software installers, cracked application downloads, or malicious browser plugins. Once it lands on a device, it silently scans and extracts saved passwords, active session cookies, and any credentials the user types or autofills while the malware is running.

The malware compiles all of this into a structured log file and sends it back to the attacker's server, usually within seconds of the initial infection. Attackers then sort these logs by volume and content, selling premium batches or, as occured here, uploading them to Telegram channels where they're freely shared among cybercriminals.

The "1.14 - LOGS_CENTEER" name suggests this was one installment in a broader series of log files, which is common with prolific stealer campaigns that bundle and distribute compromised data in numbered batches.

Check If You Were Affected
