14-JAN SECOND BASE Exposes Nearly 5,000 Plaintext Logins

HEROIC analysts found a combolist called 14-JAN SECOND BASE, dated 15-Jan-2026, containing 4,996 records of email addresses matched to plaintext passwords and the URLs each pair targets. That is nearly five thousand working login attempts in one file. Scan your email to find out if yours is one of them.

5,000 Reasons To Check Your Inbox

Every record in 14-JAN SECOND BASE pairs a real email address with a password stored in plain text, meaning nothing stands between this file and an attacker trying it. The scale alone, just four short of 5,000 pairs, makes automated testing against popular sites fast and cheap to run. A file this size is built for volume, not precision.

The Fields Collected In This Combolist

• Email Addresses: supplies the username half of each login attempt.
• Plaintext Password: supplies the other half, usable without any cracking.
• URLs: records which site each pair is meant to be tried against.

The Real Cost Of A Reused Login

When a password from a list like this still works elsewhere, the consequence is rarely limited to one account. Attackers who confirm a working pair often pivot straight to email takeover, since a compromised inbox can be used to reset passwords on nearly everything else. From there, fraud, impersonation, and locked-out owners are common and fast-moving outcomes.

Where A File Like This Comes From

A combolist is assembled from email and password pairs gathered across earlier leaks and infections, then cleaned up and grouped for reuse testing on new targets. It does not point to one company's systems being broken into, it reflects credentials recycled from multiple older sources into a single list. The value to an attacker is in trying many pairs quickly, not in where any single one started.

What Should You Change Right Now?

Scan your email first to confirm whether you appear in this file. If you do, change that password on every account where it's reused, prioritizing email and banking before anything else. Check your work email the same way, since a shared or recycled password there can expose an entire organization, not just one inbox.
