6,001 Pairs Listed in the 6393 HQ HOTMAIL COMBOLIST File

HEROIC analysts logged the 6393 HQ HOTMAIL COMBOLIST, dated February 6, 2026. The record lists 6,001 email and plaintext password pairs with URLs. The 6393 in the file name is only part of the label, so the count to rely on is 6,001.

A Name Is Not a Finding

Whoever shares a file chooses its name. The wording inside this label is the uploader's choice, and it does not confirm what the entries are, which service they belong to, or what condition they are in. Nothing in the stored record says anything about a particular company or its systems. The record states only the type, a combolist, and that the passwords are stored as plaintext.

The Three Kinds of Data Listed

• Email addresses, which name the owner of each pair and receive reset links.
• Plaintext passwords, readable without any cracking step.
• URLs, the addresses attached to each pair.

How a Pair Becomes a Risk

The risk begins when one password protects more than one login. A pair tried on a different site can open it, and an opened inbox can reset the other passwords tied to that address. For a combolist this matters more than any single entry, since the point of the file is to try pairs where they were not first used.

What Makes a Combolist a Combolist

A combolist is a merged file of email and password pairs with the sources removed, arranged so software can test the pairs against other sites. It differs from a database taken from one service because nothing in it ties the pairs to a single origin. That is why this write-up describes the file and leaves the question of origin open.

Take the Next Step

Check your own address: scan your email and see what was exposed. If a pair of yours is included, change that password on every site where you used it and use a different one for each site, beginning with email and banking. An inbox at work is as much a candidate as an inbox at home.
