Everyday Accounts Caught in the Switzerland_11_2023 Combolist Leak

HEROIC analysts discovered this combolist while sweeping Telegram for newly posted credential dumps, and found 100,192 email and password pairs filed under the name Switzerland_11_2023, each tagged with the URL it was tested against, dated August 23, 2026. Scan your email to see if you are one of them.

Why This Kind of Discovery Does Not Mean You Are Safe

Finding a file does not neutralize it; the 100,192 pairs inside were already confirmed to work before HEROIC ever came across them. Whoever downloaded the file earlier has had just as much opportunity to use it.

What the Switzerland_11_2023 File Contains

• Email Addresses: identifies which inbox each password in the file belongs to.
• Plaintext Password: already readable, so it works without any extra cracking step.
• URLs: shows which login page each credential pair was tested against.

Who Ends Up Exposed in a File This Size

A combolist this large does not single out any one type of account; it is made up of whatever email and password pairs were confirmed to work, regardless of who they belong to. Anyone whose password shows up here and gets reused elsewhere is just as exposed as the next person.

How a File Like This Gets Put Together

Combolists are built by pulling older leaked email and password pairs together, then testing the combined set against login pages to confirm which ones still work. Only the successful matches survive into the final file, which is how a list reaches well over 100,000 records.

What Should You Do About the Switzerland_11_2023 Combolist?

Scan your email to see your information and check whether you are one of the 100,192 affected. Since this password was confirmed to work through reuse rather than stolen from a device, change it on every account where you have used it, starting with anything financial. Treat work email with the same urgency, since a reused password there is just as exploitable.
