Why Check Emails Before Opening?

84% of emails are opened on mobile devices, where phishing attacks are harder to detect. A single malicious email can compromise your entire digital life.

Email remains the #1 vector for cyberattacks. According to recent data, phishing emails account for over 80% of reported security incidents. The consequences can be severe:

  • Identity theft: Criminals steal personal information to open accounts in your name
  • Financial loss: Direct theft from bank accounts or fraudulent purchases
  • Data breach: Malware installations that compromise all your devices
  • Reputation damage: Your email account used to attack others

Common Email Threats

1. Typosquatting (Most Common)

Attackers register domains that look almost identical to legitimate companies:

✓ Legitimate:paypal.com
✗ Fake:paypa1.com (L → 1)
✗ Fake:paypai.com (L → I)
✗ Fake:paypa|.com (L → |)

2. Dangerous Domain Extensions

Certain TLDs (Top Level Domains) are heavily used in phishing:

.xyz

.top

.click

.link

While not all emails from these domains are malicious, they're statistically more likely to be spam.

3. Suspicious Keywords in Domains

Phishers often use urgency-inducing words in domain names:

  • amazon-secure.com
  • verify-paypal.com
  • account-apple.com

Legitimate companies rarely use these words in their email domains.
