The attacks, explained
without the jargon

Short reads on the browser and identity attacks we catch. If you've ever had to explain one of these to a non-security exec, start here.

What is ClickFix?

It's the "paste this to fix the problem" trick. A page tells the user something broke, then walks them through copying a command and running it themselves. The user does the attacker's work, so nothing malicious has to download first.

A fake CAPTCHA. A "your browser is out of date" banner. A meeting that won't join until you "run a quick fix." Same play every time.

Fantomo watches for the tell-tale signals in the page: shell commands, Win+R prompts, paste-to-terminal instructions, device-code and consent detours. It flags or blocks the page before the command runs.

Adversary-in-the-middle, in plain terms

The user lands on a login page that looks exactly right, because it's a proxy sitting in front of the real one. They type the password. They even pass MFA. The proxy quietly pockets the session token, and now the attacker is logged in as them. MFA didn't help, because the attacker stole the session, not the password.

Fantomo fingerprints each authenticated session at the browser. When that session shows up from a different environment, that's the signal something's wrong, and you get told.

Ghost logins and the MFA you think you have

You rolled out SSO. You mandated MFA. But there's almost always a side door: a direct password login that skips the identity provider entirely. Those are ghost logins, and they don't show up in your IdP reports because they never touched the IdP.

Fantomo sees the login happen in the browser, so it can tell you which accounts are signing in with a password while SSO is supposed to be enforced, or with no MFA at all. Then you close the door.
