What a Stolen Session Actually Gives an Attacker
A session token is proof that someone already logged in. An attacker holding one stolen cookie is inside the account without the password and without triggering multi-factor authentication, because both were satisfied when the session began. Changing the password afterwards does not end it; only invalidating the session does.
That single fact is the reason this topic belongs in awareness training rather than only in engineering documentation. Staff have been taught that multi-factor authentication protects the account, and it does, right up until the moment the token is taken by malware, a malicious browser extension, or a proxy phishing page that sits between the user and the real login. What stays out of the published version is any live token or cookie value, including truncated ones, because a training asset containing a real session artefact is a liability that outlives the training.
The template follows one stolen session across seven scenes: one on what a session is in plain terms, two on the three routes by which tokens are taken, one on why the password reset is not the fix, one on the signs a user can actually notice, one on the correct report, and one on what the security team does to terminate sessions.
