Unlike regular phishing that sends millions of identical emails, spear phishing is a targeted and personalized attack. The hacker knows you — or pretends to.
What is spear phishing?
Spear phishing is an attack where the fraudster personalizes their message using information about you: your name, employer, colleagues, recent projects. The goal is to make the email so credible that you have no reason to be suspicious.
How do hackers collect this information?
- LinkedIn: Job title, employer, colleagues, projects
- Facebook/Instagram: Interests, frequented places, events
- Data breaches: Compromised databases available on the dark web
- Company website: Org chart, executive names, generic email
⚠️ Real example: "Hi [Your name], following our Monday meeting with [real colleague's name], please validate this HR document before 5pm." — This type of message comes from an address mimicking your company's domain.
How to protect yourself?
- Always verify the sender's full email address (not just the displayed name)
- When in doubt, contact the sender through another channel (phone, message)
- Limit public information on your professional profiles
- Enable 2FA to limit damage if compromised
- Be wary of urgent requests involving money transfers or sensitive data
Spear phishing warning signs
- The email uses your first name and precise personal information
- It creates urgency: "before 5pm", "within the hour"
- It requests an unusual action (transfer, confidential data)
- The email address looks like your company's but isn't exact
