Why Am I Getting Spam Emails That Look Legit?
Discover why fake emails from 'PayPal' or 'Amazon' often bypass filters and how the mechanics of email spoofing work.
Why Am I Getting Spam Emails That Look Legit?
Have you ever received an email that looked exactly like it came from your bank, PayPal, or even your own boss, only to realize later it was a scam? You aren't alone. This technique, called Email Spoofing, is one of the most common ways hackers gain access to sensitive information.
The Mechanics of Trust
When email was invented, it wasn't built with security as a priority. Much like a physical envelope, anyone can write a fake "Return Address" on an email. The email system, by default, doesn't verify if the sender actually owns the domain in the "From" field.
SPF, DKIM, and DMARC: The Defenders
To combat this, three technologies were created to verify sender identity:
- SPF (Sender Policy Framework): A list of servers allowed to send email for a domain.
- DKIM (DomainKeys Identified Mail): A digital signature added to every email to prove it wasn't tampered with.
- DMARC (Domain-based Message Authentication, Reporting, and Conformance): The "Instruction Manual" for what to do if SPF or DKIM fails.
If a company hasn't set up DMARC enforcement, a hacker can easily send an email that looks 100% legitimate to your inbox filter.
Real-World Example: The CEO Scam
Attackers often target employees by spoofing the CEO's email address. Because the display name says "CEO NAME" and the email address looks correct, employees may follow urgent instructions to wire money or share passwords.
