The Logs_27 May Stealer Data Quietly Hit Telegram: 37,347 Exposed

HEROIC analysts noticed a stealer log titled "Logs_27 May" quietly appear on a public Telegram channel on May 27, 2025. Unlike a headline-grabbing corporate breach, this one arrived with no fanfare, but the file still contained 37,347 records tied to United States based accounts, including email addresses, plaintext passwords, and the URLs of the login pages those credentials belonged to.

Why This Is Dangerous

Quiet leaks like this one are often the most overlooked, since they never make the news and rarely trigger a company breach notification. Yet the passwords in this file are stored in plaintext, meaning there is no encryption standing between an attacker and a working login, and the matching URL for each account tells an attacker exactly where to try it. With 37,347 records, this log passed through Telegram with little notice while still putting a large number of people at real risk.

What Was Exposed in the Logs_27 May Leak

• Email addresses
• Plaintext passwords
• URLs of the associated login accounts

Why This Matters for the 37,347 Affected Accounts

An email, password, and login URL bundled together is everything an attacker needs to attempt account takeover with no guesswork. If anyone among these 37,347 accounts reused their password elsewhere, the same combination can be tested against banking, email, and shopping sites in minutes through automated credential stuffing tools. From there, the risk extends directly into identity theft and financial fraud, since a compromised email account is often the key to resetting passwords on everything else tied to it.

How a Stealer Log Like This One Goes Unnoticed

A stealer log is the output of malware that infects a device and silently collects whatever login data it can find, typically credentials saved in a browser, autofill entries, and active session data. The infected machine sends this haul back to the attacker, who compiles it into a dated file and drops it into a Telegram channel or dark web forum, often without any announcement. Because there is no company statement or press coverage attached to a leak like this, it can sit online for a long time before affected users ever learn their credentials are exposed.

Check If You Are Affected

Quiet leaks like this one are exactly why regular checking matters, since there is no notification email coming. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer log dumps like this one, to tell you whether your email address has surfaced in a known breach. If it has, change the affected password immediately, along with any other account where you reused it.
