Unit 1: Who attacks and how · Lesson 1 of 4 · 16 min

Who attacks and why

Build a one-line threat profile for Northwind from the actor list.

mission

You are
A new analyst in Northwind Freight's SOC.
Situation
Your manager asks who is most likely to attack a freight company and what they would go after. The intel team keeps a short actor list on the workstation.
Goal
Read the list and name the actor that matters most to Northwind, with its motive and methods.
Hand in
One sentence: who, why and how they usually get in.
01

Open the case folder

Every case on this workstation starts with a README. Read it before touching the data so you know what each file is.

analyst@soc-lab
ls
README.txt
actors.csv
alerts.csv
stages.txt
cat README.txt
Case: IR-2026-0921, closed

Last month's intrusion, kept for training. The SIEM tagged every alert
with the stage of the attack it belongs to.

Files:
  actors.csv    who attacks companies like Northwind, and why
  stages.txt    the stages of an attack, in order, and what you see
  alerts.csv    every alert from the incident, oldest first

you should see Three files: actors, stages and alerts.

02

Read the actor list as a table

CSV is hard to scan raw. column lines the fields up so you can compare rows.

analyst@soc-lab
column -s, -t actors.csv
actor                       motive              targets                           methods
financially motivated crew  money               finance teams and payroll         invoice fraud; gift card scams; ransomware
hacktivist group            ideology            public websites                   defacement; leaks; denial of service
insider                     grievance or money  data they can already reach       copying files; misusing access
state-backed group          espionage           suppliers and logistics data      long quiet access; stolen credentials
opportunist                 easy wins           anything exposed to the internet  scanning; default passwords; old software

you should see Each row pairs a motive with the targets it leads to.

defender tip Motive predicts targets. A crew after money goes for whoever can move money, so finance and payroll get the most phishing.

03

Filter for what Northwind has

Northwind moves money to suppliers every day. Filter the list for the actors that go after finance.

analyst@soc-lab
grep -i finance actors.csv
financially motivated crew,money,finance teams and payroll,invoice fraud; gift card scams; ransomware
grep -i finance actors.csv | cut -d, -f4
invoice fraud; gift card scams; ransomware

you should see Invoice fraud and gift card scams lead the methods list.

04

Check who wants the logistics data

Freight data, routes and customers, is worth something to a different actor. Look for it too.

analyst@soc-lab
grep -i logistics actors.csv | cut -d, -f1,2
state-backed group,espionage

defender tip Espionage actors are quiet and patient. They show up as odd logins weeks apart, not as loud alerts.

Two ways to brief your manager

Vague profile
Threat: hackers
Risk: high
Action: be careful
Useful profile
Threat: financially motivated crew
Wants: supplier payments
How: invoice fraud, gift card scams
Watch: bank-change emails to finance

Specific enough to decide what to monitor first.

What a defender takes away

  1. 1Attackers have motives, and motives predict targets.
  2. 2For a company that pays suppliers, money-driven crews are the first threat to plan for.
  3. 3A good threat profile names who, what they want and how they get in.
