What's inside

3 things your team will use immediately

The playbook isn't theory. Every section is designed to be used — by your help desk agent at 9am, by your CFO when a "vendor" calls, and by your whole team in the first 60 minutes of an incident.

🚩

Spot 5 call-based attack patterns before they escalate

Each red flag includes the exact language to listen for, why it's dangerous, and what to do instead. Includes a decision tree for your help desk.

📋

Copy-paste the help desk verification script your team will actually use

Word-for-word script with call flow instructions. Post it next to every help desk terminal. Tested in real vishing scenarios.

⏱

Step-by-step incident response playbook for the first 60 minutes

Detect → contain → eradicate → recover. Each phase with a time stamp and specific action items your team can execute without a security degree.

How it works

From phone call to full breach in 12 minutes

The playbook includes a fully anonymized teaching case from a 2026 breach — a tech company whose help desk received one call and ended up exposing nearly a million records. Step-by-step chain breakdown inside.

Reconnaissance

Attacker scrapes LinkedIn and job postings to learn your org structure, vendor names, and employee titles.

Days–weeks before

Callback Spoofing

Caller ID is spoofed to display "IT Help Desk" or your vendor's number — not a random external call.

Minutes before

The Call

Professional, confident, cites a specific system or vendor. Uses your company name and known tools.

0–5 min

Credential Extraction

"I need you to confirm your password so I can run a diagnostic." MFA codes included.

5–15 min

Account Takeover

Attacker logs in. Uses MFA fatigue — 15 push requests until the victim approves out of frustration.

15–30 min

Data Exfiltration

Lateral movement to cloud storage, CRM, and HR systems. Full breach by the time you notice.

30–180 min
