One Month Later: AYANKOUJI 499 Leak’s 3,920 Logins Still Exposed

It has been about a month since the stealer log known as AYANKOUJI Private 499 first appeared on Telegram on June 1, 2026, and in that time its 3,920 records of email addresses, plaintext passwords, and URLs have had plenty of opportunity to circulate further.

A month might not sound like a long time, but in the world of leaked credentials, it is more than enough for a file to get copied, reposted, and passed between channels untill nobody can trace where it originally came from.

Why This Is Dangerous

The longer a file like this sits out in the open, the more people download it, and every one of those 3,920 password and email pairs is stored in plaintext, ready to use with no extra work needed. The passage of time does not make these credentials any safer, if anything it gives criminals more chances to test them against other accounts.

What Was Exposed

• Email addresses for 3,920 accounts
• Plaintext passwords attached to each entry
• URLs showing the exact services the logins belong to
• 3,920 total records confirmed in the AYANKOUJI Private 499 file

Why This Matters

One noticable problem with older leaks is that people assume the danger has passed simply because time has gone by. In reality, credentials from a leak like this can still be actively traded weeks or months later, especially if the affected passwords were never changed.

How Stealer Logs Work

Stealer logs are created by malware that silently harvests saved logins from an infected browser, then packages everything into a file for the attacker. Once uploaded to a place like Telegram, that file does not just disappear, it gets downloaded, copied, and often reposted under new names for months afterward.
