The ‘358 Russian Full Valid’ Leak: 216 Passwords Exposed. Check Now.

In May 2026, HEROIC analysts identified a small combolist titled "358 Russian Full Valid" that a Telegram user uploaded, tied to a leak date of May 8, 2026. The file contains 216 records pairing email addresses with plaintext passwords and URLs. Why This Is Dangerous: The word "Valid" in the filename suggests these 216 credentials were checked and confirmed to work before being uploaded, meaning every entry in this small file is more likely to be an active, usable login rather than an old or dead account. What Was Exposed: - Email addresses - Plaintext passwords - URLs showing which site or service each credential pair unlocks Why This Matters: A small file of confirmed-working credentials is arguably more dangerous per record than a massive dump full of stale or duplicate entries. If your login is one of these 216, an attacker already knows it works, and if you reuse that password anywhere else, credential stuffing can quickly turn one compromised account into several, opening the door to identity theft and financial fraud. How a Combolist Like This Works: A "full valid" combolist means the credentials have been tested against live login pages before distribution, filtering out anything that no longer works. Criminals build these curated lists from larger breach dumps, phishing catches, or stealer logs, then sell or share the verified portion on Telegram, since a smaller list of guaranteed logins is often more valuable than a large unverified one. Check If You Are Affected: Because every credential in this file was verified as working, checking your exposure now matters. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, so you can find out immediately and change your password before someone else uses it.
