If You Reuse Passwords, the 5.26 – LOGS_CENTEER Leak Should Worry You

HEROIC analysts found a stealer log file uploaded to a public Telegram channel on May 26, 2023, by a user identified as LOGS_CENTEER. The dataset, labeled 5.26 - LOGS_CENTEER, contained 22,834 records each holding an email address, a plaintext password, and the URL of the associated service. The log was gathered from compromised user devices through infostealer malware and distributed widely through Telegram, making it accessible to a large number of bad actors.

Why This Is Dangerous

Every record in this file is a ready-made key to someone's account. Plaintext passwords mean there is nothing standing between an attacker and a successful login attempt. Add in the service URL and attackers know exactly where to try each credential. With 22,834 such records available for free download, automated account takeover tools can process the entire file in a matter of minuets.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• Service URLs

Why This Matters

Files like the LOGS_CENTEER 5.26 dump are the raw material for credential stuffing attacks. Criminals load all 22,834 pairs into automated scripts and test them against banks, email services, streaming platforms, and online stores in parallel. If you have ever reused a password on more than one site, a single hit in this file can cascade into multiple compromised accounts. Beyond account takeovers, exposed email addresses become targets for phishing campaigns and fraud, extanding the damage well beyond a single login.

How Stealer Log Breaches Work

Infostealer malware is the engine behind every file like this one. The malware typically arrives as a trojanized software installer, a cracked game, or a link in a phishing message. Once active on your device, it silently harvests every password stored in your browser, every credential you type into a login form, and the URLs associated with each one. That data is sent back to the attacker's server and compiled into structured log files. Those files are then shared or sold through Telegram channels like the one LOGS_CENTEER used, putting your credentials in front of thousands of potential attackers at once.
