Day 2: Safe or Spoofed?

Students will define integrity and identify how it appears in cybersecurity work by analyzing message evidence and choosing a safe professional response.

Daily Learning Contract

  • Topic: Phishing and Integrity
  • Objective: Students will define integrity and identify how it appears in cybersecurity work by analyzing message evidence and choosing a safe professional response.
  • TEKS: d(4)(F)
  • Demonstration of Learning: Students classify seven messages, explain the hardest decision with visible evidence, state the safe response, and name one integrity behavior a cybersecurity worker demonstrates.

Lesson Overview

Time 50 minutes
District HQIM FYF pp. 24-25, Safe or Spoofed?
Locked visual source Climber Notes slides 2-8, embedded individually in Canvas
Materials Seven email images, Phishing Red-Flag Checklist, workbook or Canvas guide

Before Students Arrive

  1. Open all seven locked email images in Canvas and confirm they are readable from the back of the room.
  2. Post or print the Phishing Red-Flag Checklist.
  3. Keep the answer guidance on the unpublished teacher page. The Climber Notes deck has no speaker-note key.
  4. Post the response sequence: Pause. Verify independently. Report. Delete.

Bellringer — Evidence Before a Decision (5 min)

Project Email 1 without asking students to click anything.

Prompt: Name one thing you can see that should slow you down. Do not decide yet.

Take two observations, then separate observation from decision: “The sender is freerewards@prize-center123.net” is visible evidence. “It is spoofed” is the decision supported by that evidence.

Activity 1 — Five Red Flags (10 min)

Use FYF p. 24 and teach one clue at a time:

  1. strange sender address;
  2. urgent or emotionally loaded language;
  3. request for private information;
  4. suspicious link or attachment; and
  5. spelling or grammar problems.

Two boundaries matter:

  • one typo does not automatically make a message fake; and
  • a polished message with no obvious flags is not automatically safe.

Hovering may preview a link on a desktop, but it does not verify the sender. On touch devices, students use the visible domain and verify through a trusted route.

Activity 2 — Seven-Email Investigation (23 min)

Open one email at a time. Students first mark visible clues, then choose Safe-looking or Spoofed. Use Safe-looking, not “proven safe,” for Emails 3 and 7.

After Email 4, pause for a Think-Pair-Share:

“The strongest clue is ___ because . The safe next action is .”

Both partners record their own evidence. Students do not need to circle directly on a projected image; the checklist supplies accessible labeled fields.

Activity 3 — Safe Practice Draft (7 min)

Preserve the FYF practice extension with firm boundaries. Students draft on paper or in the assigned private document only. They use a fictional organization, fictional person, and an example.com address. They may include two written red flags, but they may not include a working link, QR code, attachment, password request, real credential, real person's name, or Irving ISD impersonation. The message is never sent or posted.

If time is tight, the draft becomes a two-line subject/sender/message sketch instead of a full email.

Exit — Professional Response and Integrity (5 min)

Students finish three lines:

  1. The hardest email was ___ because ___.
  2. Instead of clicking or replying, I would ___.
  3. A cybersecurity worker shows integrity by ___ because ___.

Teacher Key

Email Decision Visible evidence and safe response
1 Spoofed Prize pressure, odd sender, unrelated claim link. Report and delete.
2 Spoofed amaz0n uses a zero; order-check domain is not the official company site. Verify through the official order history.
3 Safe-looking Company HR sender, ordinary reminder, no link or private-information request. If uncertain, verify through the known HR contact or official portal.
4 Spoofed .co sender, TODAY pressure, unrelated update domain. Use the official benefits portal instead.
5 Spoofed Account-suspension pressure, one-hour deadline, unrelated fix domain. Contact known IT support.
6 Spoofed .co sender and portal-login link. Open the known portal independently.
7 Safe-looking Ordinary manager note, no link, attachment, or private-information request. Verify through the known manager/channel if anything feels unusual.

Supports

  • Read sender and domain strings aloud and enlarge the image when needed.
  • Use the frame: “I marked ___ because I can see ___.”
  • Let pairs discuss before each individual decision.
  • Provide a text description of visible evidence for low-vision access without announcing the answer.
  • Score evidence and revision, not whether the student's first call matched the key.

If a Student Is Absent or a Device Is Unavailable

The seven locked images and checklist are the complete independent route. No live email account, link, or partner is required.
