Records Exposed 469
Source Type Combolist
Origin United States
Password Type plaintext

Every one of the 469 records in this Telegram combolist pairs an email address with a plaintext password, and HEROIC's analysts dated the upload to 14 November 2020, not the date suggested by the file's own label. Small as it is, each password in the set is stored in the clear and ready to use. Check your exposure with a free scan your email.

Why this is dangerous

A reused plaintext password doesn't stop at one login. If it unlocks a login in this file, the same password likely unlocks something else too, whether that's an email inbox, a shopping login, or a work tool, and an attacker only needs to find the first match to start pulling that thread.

What was exposed

  • Email addresses, identifying each credential pair.
  • Plaintext passwords, readable and reusable without cracking.
  • Login URLs, showing the exact service each pair was pulled from.

Why this matters

Small files like this one are easy to dismiss, but 469 working credential pairs is still 469 chances for a chain reaction. One reused password found here can lead an attacker to a second login, and from there to a third, especially if the same email address is used broadly.

How this breach type works

Combolists like this one are built from earlier leaks and malware harvested credentials rather than a direct hack of any single company. The danger comes from credential stuffing, where attackers automatically test each pair against a wide set of other login pages until something works.

How far could this chain reach for you?

Start with a free scan your email to see whether your address is one of the 469. If it is, change that password everywhere you've reused it, not just on the one login this file names. Do the same check for any work email, since a chain like this doesn't stop at personal logins.
