Why Social Engineering Works
Every attack exploits one or more psychological principles:
Principle
How Attackers Use It
Example
Authority
Impersonate someone with power
"This is the CEO, wire transfer now"
Urgency
Time pressure prevents thinking
"Account locked in 30 minutes"
Fear
Panic supersedes judgment
"Unauthorized access detected"
Trust
Leverage existing relationships
Email that looks like your bank
Reciprocity
Create obligation
"I helped you, can you share this file?"
Curiosity
Offer something tempting
"See who viewed your profile"

Phishing Example Analysis
Account Verification Phish
From: security@amaz0n-verify.com
Subject: Action Required: Verify Your Account Information
Dear Valued Customer,
We detected unusual activity. Verify within 24 hours or
your account will be suspended. [Click here to verify]
Red flags: Zero in domain, generic greeting, urgency + threat, link to provide info.
Spear Phishing (Targeted)
From: j.smith@yourcompany.co (real domain is .com)
Subject: RE: Q3 Budget Review
Can you look at the updated budget spreadsheet?
[budget-review-Q3.xlsm]
Red flags: .co vs .com domain, macro-enabled file (.xlsm), references a plausible conversation.
When You Suspect Phishing
1. Do NOT click links, open attachments, or reply
2. Navigate to the company's website directly (type URL yourself)
3. Log in and check for actual notifications
4. Report: forward to the impersonated company and your IT team
5. If you already clicked: change password immediately, enable 2FA,
monitor the account, contact your bank if financial info was shared
Vishing (Voice Phishing)
Common Scenarios
Bank Fraud Alert: "We detected suspicious activity. Verify your account number and PIN."
Reality: Your bank never asks for your full PIN over the phone.
Tech Support Scam: "This is Microsoft. We detected a virus. Give me remote access."
Reality: Microsoft does not make unsolicited support calls.
Government Impersonation: "This is the IRS. Pay immediately by gift card or face arrest."
Reality: The IRS contacts by mail first and never demands gift cards.
Reality: Always verify by calling the family member's known number.
Vishing Defense Protocol
1. RECOGNIZE the pressure (urgency, fear, secrecy, unusual payment)
2. REFUSE to provide passwords, PINs, verification codes, SSN, or remote access
3. VERIFY independently - hang up, look up the real number, call back
4. DOCUMENT the caller's claimed identity, phone number, and what they asked for
KEY RULES
- Caller ID is NOT proof of identity (it can be spoofed)
- No legitimate org asks for payment via gift cards
- No legitimate org threatens arrest by phone
- Government agencies contact you by mail first
Pretexting
Pretexting is fabricating a scenario to extract information through a multi-step conversation.
Common Scenarios and Defenses
"I'm the new IT admin. Verify your password for the migration."
--> IT never needs your password. Verify with your actual IT team.
"This is [Vendor]. Verify the bank account for your refund."
--> Contact the vendor through your existing verified contact.
"We're doing a security audit. What antivirus and VPN do you use?"
--> Security audits come through official internal channels.
"I have a package for someone, can you buzz me in?"
--> Do not grant building access to unverified people.
The STOP Method
S - STOP before responding. Pause when something feels unusual.
T - THINK about what is being asked. Why do they need this?
O - OBSERVE the details. Are they avoiding verification? Pressuring you?
P - PROTECT by verifying through a separate channel.
Verification Protocols
The Callback Method
PHONE: Hang up. Look up the official number. Call back yourself.
EMAIL: Do not reply or click. Navigate to the website directly.
IN-PERSON: Ask for ID. Call their organization at a known number.
The Two-Channel Rule
Never verify a request using the same channel it arrived on:
Request via: Verify via:
Email -> Phone call or in-person
Phone call -> Separate call to known number
Text message -> Phone call to known number
In-person -> Phone call to their organization
Social media -> Email or phone to known contact
Verification Script
"I want to help, but policy requires me to verify this request.
Let me [call/check/verify] and I'll get back to you by [timeframe]."
This is polite, firm, and puts you in control of the next contact.
