Nobody Hacked Anything

Social engineering: phishing, vishing, tailgating, and how to stop them

Read the comic Open the lab sheet

The reading is a comic. Students follow Dee, a student IT intern, through one morning and three attempted cons: a fake IT phone call, a phishing email and a stranger at the back door. Then they sort a real-looking inbox, run phone calls against a verification checklist, and write the incident report.

The reading is a comic. It replaces a textbook passage: every key term is defined in a caption with an example and a non-example, the process and the figure are drawn as panels, and it ends with a Summary. A plain-text version sits under it. Read it.

Objectives

Students will be able to:

  • Define social engineering, vishing, phishing, smishing, tailgating, impersonation and urgency, and give an example and a non-example of each.
  • Identify the warning signs in a phishing email.
  • Apply verification: contact a person through a number or address already known to be real.
  • Write an incident report that another technician could act on.

Board question

  1. Name one thing someone could get from you without ever touching your computer.
  2. Describe, in one sentence, a call, text or email that made you suspicious. Leave out anything private.

Students answer in the notebook at the start, and revisit the answer on the exit ticket.

Materials

  • The comic, on Chromebooks or printed in color (12 panels).
  • Lab sheet (printed), one per student.
  • Phone-call role cards (on the lab sheet: one caller card and one receiver checklist per pair).

Before class

  • Decide how students read the comic: on Chromebooks, or printed. It prints in color and stays readable in grayscale.
  • Find your school's real help desk number and how staff report a suspicious email, so Part C and the debrief use the real procedure.

Vocabulary

Social engineering
Tricking a person into giving up information or access, instead of breaking into a computer.
Impersonation
Pretending to be someone the person trusts.
Urgency
Pressure to act right away, so the person acts before thinking.
Vishing
Social engineering over the phone.
Phishing / smishing
Social engineering by email / by text message.
Tailgating
Following an authorized person through a secured door without using a badge.
Shoulder surfing
Watching someone type a password or PIN.
Verification
Contacting the person through a number or address you already know is real.

Exit ticket

Item 1 is always the board question, revisited. Then:

  1. A user receives a call from someone who says they are from IT and asks for the six-digit code that was just texted to the user. What type of attack is this?

    1. Phishing
    2. Vishing (key)
    3. Tailgating
    4. Shoulder surfing
  2. An employee holds a secured door open for a person carrying boxes who has not used a badge. What is this an example of?

    1. Tailgating (key)
    2. Smishing
    3. Impersonation by email
    4. Dumpster diving

Support

  • The comic carries the reading in pictures and short captions, with a plain-text version under it that works with screen readers and translation tools.
  • Part A questions point to the exact panel.
  • In Part C the teacher can play the caller for students who prefer not to perform.

Stretch

  • Write a training phishing email with three warning signs, and swap with a partner to find them.
  • Research one reported attack on a school district and identify which kind of social engineering it used.

Where this leads

Help desks are the front line for social engineering: technicians take these calls, see these emails first and write the reports. A student who can explain the code con and write a clean incident report has a strong interview answer.
