8,539 Logins for Fanfunmarket.co.jp Surface Weeks Later

If you have shopped or signed up anywhere using an email and password you still use today, this is worth checking: a combolist tied to fanfunmarket.co.jp, holding 8,539 logins, was tested on August 23, 2026, and only surfaced on HEROIC's radar weeks later. Scan your email to see if yours is one of them.

Why a Few Weeks' Delay Does Not Help You

The gap between when this list was tested and when it was found does not buy anyone extra safety. Every password in it has been sitting ready to use the entire time, whether or not anyone outside the original group of attackers knew about it yet.

What the Fanfunmarket.co.jp Combolist Holds

• Email Addresses: identifies which inbox each password in the file belongs to.
• Plaintext Password: fully readable, so it works without any extra effort.
• URLs: confirms fanfunmarket.co.jp as the login page each pair was tested against.

What Weeks of Unnoticed Exposure Can Add Up To

The longer a working password sits unnoticed, the more chances an attacker has had to try it elsewhere. If it was reused on an email or banking account, that account could already be compromised by the time you read this.

How a List Like This Gets Tested and Confirmed

Combolists are built from older leaked email and password pairs, then run automatically against login pages such as fanfunmarket.co.jp to see which combinations still work. Only the pairs that succeed make it into the final file, which is why every entry carries a confirmed track record by the time it surfaces.

What Should You Do About the Fanfunmarket.co.jp Logins?

Scan your email to see your information and check whether you are one of the 8,539 affected. Since this password was confirmed through reuse rather than stolen from a device, change it everywhere you have used it, starting with your most important accounts. Treat a work email address with the same urgency, since the delay before discovery gave attackers just as much time either way.
