🛡️ Threat Intelligence: Your Cyber Security Spy Network
Imagine you’re a superhero protecting your city. You need to know who the bad guys are, what tricks they use, and how they attack. That’s exactly what Threat Intelligence does for computers!
🎯 The Big Picture
Think of Threat Intelligence like a neighborhood watch for the internet. Just like neighbors share information about suspicious strangers, security teams share information about digital bad guys (hackers).

📡 Threat Intelligence Feeds
What Is It?
A threat intelligence feed is like a news channel for cyber dangers. It constantly tells you about new bad guys and their tricks.
Simple Example
Imagine you have a magic walkie-talkie that whispers:
- “Watch out! A thief named ‘BadBot’ is trying door handles on Oak Street!”
- “Alert! Someone is leaving fake letters that steal your information!”
Real Cyber Example:
- A feed tells you: “IP address 192.168.1.100 is attacking computers today”
- Your computer blocks that address before it can hurt you!
Types of Feeds
| Feed Type | What It Tells You | Like… |
|---|---|---|
| IP Feeds | Bad computer addresses | A list of troublemaker houses |
| Domain Feeds | Dangerous websites | A list of fake stores |
| Hash Feeds | Evil files | A list of poisoned candy |
| Vulnerability Feeds | Weak spots | A map of unlocked doors |
Why It Matters
Without feeds, you’re fighting blind. With feeds, you know exactly where to look and what to block!
🤝 Threat Intelligence Sharing
What Is It?
Sharing threat intelligence means telling your friends about dangers you discovered. If you found a trap, you warn others so they don’t fall in!
Simple Example
You see a hole in the playground that could hurt someone:
- You tell your teacher ✅
- Teacher tells other teachers ✅
- All kids get warned ✅
- Hole gets fixed! ✅
Real Cyber Example:
- Company A finds a new virus
- They share it with Company B and C
- Now everyone can protect themselves!
Sharing Groups (ISACs)
ISAC = Information Sharing and Analysis Center
Think of it as a secret club where similar businesses share secrets:

The Golden Rule
The more we share, the safer we ALL become!
🧙♂️ Pro Tip: Sharing isn’t tattling—it’s protecting your whole community!
🎯 MITRE ATT&CK Framework
What Is It?
MITRE ATT&CK is like a playbook of every sneaky move hackers use. It’s a giant encyclopedia that says: “Here are ALL the tricks bad guys might try.”
ATT&CK stands for:
- Adversarial
- Tactics
- Techniques
- &
- Common
- Knowledge
Simple Example
Imagine a book that lists every way a robber could break into houses:
- Pick the lock 🔓
- Climb through window 🪟
- Pretend to be delivery person 📦
- Copy the key 🔑
Now you know ALL tricks, so you can protect against ALL of them!
The ATT&CK Matrix

Main Tactics (Goals)
| Tactic | What Bad Guys Want | Like… |
|---|---|---|
| Reconnaissance | Learn about you | Spying on your house |
| Initial Access | Get inside | Picking your lock |
| Execution | Run their plan | Starting their mischief |
| Persistence | Stay hidden | Hiding in your closet |
| Privilege Escalation | Get more power | Stealing the master key |
| Defense Evasion | Avoid getting caught | Wearing a disguise |
| Credential Access | Steal passwords | Copying your diary code |
| Discovery | Look around | Snooping in your room |
| Lateral Movement | Move to other places | Going room to room |
| Collection | Gather what they want | Filling their bag |
| Exfiltration | Escape with goods | Running away |
| Impact | Cause damage | Breaking your toys |
Why It Matters
When you know all the tricks, you can:
- ✅ Build better defenses
- ✅ Spot attacks faster
- ✅ Explain attacks clearly to your team
🚀 Fun Fact: Security teams worldwide speak the same “language” thanks to ATT&CK!
⛓️ Cyber Kill Chain
What Is It?
The Cyber Kill Chain shows the 7 steps hackers follow when attacking. If you stop them at ANY step, you win!
Simple Example
A burglar’s plan to steal cookies:
- Find a house with cookies 🏠
- Pick the best tool to break in 🔧
- Deliver the tool to the house 🚗
- Use the tool at the door 🚪
- Install a secret way to come back 🚪➡️
- Control everything remotely 📱
- Steal all the cookies! 🍪
If mom catches them at step 3 (delivery), no cookies are stolen!
The 7 Stages

Each Stage Explained
| Stage | What Happens | Defense Idea |
|---|---|---|
| 1. Reconnaissance | Bad guy researches you | Hide your information |
| 2. Weaponization | They build an attack tool | (Hard to stop - it’s secret) |
| 3. Delivery | They send the attack (email, USB) | Block bad emails/websites |
| 4. Exploitation | Attack finds a weakness | Patch your software! |
| 5. Installation | They plant a backdoor | Watch for new programs |
| 6. Command & Control | They control your computer | Block suspicious traffic |
| 7. Actions | They steal/destroy | Limit what they can access |
The Power of “Breaking the Chain”
Stop them EARLY = Less damage!
The earlier you catch them, the better:
- Stage 1-2: They’re just planning 📋
- Stage 3-4: They’re trying to get in 🚪
- Stage 5-7: They’re already inside! 🚨
