South Korea Telegram Leak: 38,332 Logins, More Than Latvia’s Log

South Korea Stealer Log Surfaces With 38,332 Records

HEROIC analysts identified a stealer log file named "South Korea" that was uploaded to Telegram on February 18, 2023. The file contains 38,332 records, each pairing an email address with a plaintext password and the URL of the site the login was tied to. To put that in perspective, it is a larger haul than several other stealer logs HEROIC tracked from the same uploader that same week, showing how quickly these files can accumulate real volume even when they are treated as routine, disposable content by the people posting them.

Why This Is Dangerous

Every one of the 38,332 passwords in this file is stored in plaintext, meaning an attacker can use it the instant they open the file, with no cracking or decoding required. Each record already links a specific email address to its password and the exact website it unlocks, effectively handing over a working login on a silver platter. That level of readiness is what makes stealer logs especially efficient for criminals running large-scale attacks.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs and endpoints tied to each login

Why This Matters

When a password is reused across multiple accounts, a single leaked credential can unlock far more than the original site. Attackers rely on this through credential stuffing, feeding large batches of leaked email and password pairs into automated tools that test them against banking, shopping, and social media platforms. A successful match can lead to account takeover, financial fraud, or identity theft, especially if the compromised account controls access to other services.

How Stealer Logs Work

Stealer malware infects a device through channels like pirated software, fake game cheats, or malicious email attachments, then quietly extracts saved passwords, autofill entries, and browser session data. That stolen information is compiled into a log file and sent automatically to the attacker, usually through a Telegram bot designed for this exact purpose. Files like this one are often posted publicly and for free to build a reputation, while more targeted or verified logs are typically reserved for private sales.

Check If You Are Affected

With 38,332 records in this file, checking your exposure only takes a moment. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this one, so you can confirm whether your information is at risk and act before someone else does.
