Certifiedinfosec.com Logins: 65,120 Exposed in August 2026

HEROIC analysts reviewed a combolist file tied to Certifiedinfosec.com, uploaded to a Telegram channel in August 2026. The file lines up 65,120 entries pairing email addresses with plaintext passwords and the web address each pair worked on. This is a list of logins for Certifiedinfosec.com, not proof that the site itself was hacked. The only way to know if you are on this list is to scan your email.

Why a Certification Site Login Carries Weight

Accounts on training and certification sites often sit untouched for months, which makes people more likely to forget the password or reuse an old one from elsewhere. That is exactly what makes a leak like this one valuable to an attacker testing stolen passwords against more active accounts.

What This Combolist Contains

• Email addresses: identify exactly whose login each entry belongs to.
• Plaintext passwords: readable immediately, with no cracking needed before an attacker tries them.
• URLs: show which site the pair came from, pointing straight at Certifiedinfosec.com.

From One Old Account to Several New Problems

The real damage rarely stops at the original site. Once a plaintext password is out, attackers run it against email providers, workplace logins and banking sites, since a password reused from an old training account can just as easily unlock something people actually care about protecting.

How a File Like This Takes Shape

A combolist is built by pulling email and password pairs from many scattered leaks and reused password lists, then tagging each one with the site it worked on. The entries here were collected over time from existing stolen credentials rather than from one single break in.

Does Your Certifiedinfosec.com Login Appear in This File

Take a minute to scan your email and see if your login appears in this exposure. If it does, change that password immediately, and anywhere else you used the same one, since plaintext credentials can be tried the moment someone opens the file. Check this for both your personal and work email addresses.
