When we think about online security, we think of passwords.
But in today’s AI-driven world, there’s something even more valuable than your password — and most people don’t even know it exists: session tokens.

If Zenity’s Black Hat 2025 demo taught us anything, it’s this: attackers aren’t always after what you type in at login. They’re after the invisible digital “passes” that keep your AI and connected systems talking to each other.

What’s a Session Token, Really?

Here’s a simple analogy:

• Your password is your house key.

• Your session token is the visitor’s pass the front desk gives you after you’ve already shown ID.

Once you’re inside, you don’t need to keep flashing your key at every door — the token lets you move freely for a set time.

AI systems rely on these tokens to save you from re-entering your password every time you:

• Pull a document from Google Drive

• Ask Salesforce for customer data

• Send an email draft through Outlook

Tokens make things seamless. But they also make things risky.

Why Hackers Love Tokens

Attackers want session tokens because:

1. They Bypass Passwords and 2FA
   If a hacker steals or forges a valid token, they don’t need your login or your text-message code. They already have “proof” of identity.

2. They Last Longer Than You Think
   Some tokens stay active for hours, days, or even weeks — plenty of time for attackers to dig around.

3. They Travel Widely
   Tokens don’t just sit in one place. They get passed between your AI system and every connected service — which multiplies the chances for interception.

4. They’re Invisible to You
   Unlike a stolen password, you don’t know when a token is compromised. There’s no email saying, “Your session token was used in another location.”

How Tokens Power Zero-Click Attacks

The “zero-click” nature of Zenity’s exploit rests on this token weakness.
Here’s how it might unfold:

1. The attacker starts with your email address (easy to find).

2. They exploit a flaw in how the AI platform issues or validates tokens.

3. The platform wrongly gives them a valid token tied to your account.

4. With that token, they now have full access — past chats, future chats, and all connected integrations — no password required.

That’s why this is so dangerous. You could have the world’s strongest 20-character password with symbols and numbers, but if a hacker gets your session token, it doesn’t matter.

Real-World Dangers of Token Theft

• Corporate Espionage
  Hackers intercept tokens tied to a CEO’s AI account and siphon sensitive strategic plans.

• Supply Chain Attack
  A compromised AI token connected to cloud storage plants malicious files in shared drives, spreading to partners and vendors.

• Stealthy Surveillance
  Attackers silently monitor future conversations, watching product roadmaps and legal strategies unfold in real time.

Protecting Against Token Exploits

While vendors like OpenAI and Microsoft are now patching vulnerabilities, organizations still need to take responsibility. Here’s how:

1. Force Short Token Lifespans
   Limit how long a token remains valid before requiring re-authentication.

2. Rotate and Revoke Regularly
   Treat tokens like digital keys — change them often, revoke unused ones immediately.

3. Segment Permissions
   Don’t let a single token unlock access to all systems. Use different tokens for different services.

4. Enable Session Monitoring
   Configure alerts for unusual token activity — like sudden logins from new locations.

5. Educate Teams About “Invisible Credentials”
   Make sure employees know tokens matter as much as passwords. This builds the culture shift needed for AI security maturity.

The Bottom Line

Session tokens are the new crown jewels of the hacking world.
They don’t just open the front door — they keep it open indefinitely.

As AI platforms like ChatGPT become central hubs for business operations, the value of these tokens only grows. Hackers know this. That’s why we need to start treating tokens with the same seriousness as we treat passwords and multi-factor authentication.

The Zenity exploit wasn’t just a one-off bug. It was a flashing red warning: AI platforms are now high-value targets, and token security is the battlefield.
