Beware of unsolicited emails: Never open attachments or click on links from unknown senders, even if they appear legitimate.
Verify the sender: If you receive an email from someone you know, double-check the sender’s address for any suspicious variations.
Hover over links: Before clicking, hover over the link to see the actual URL it leads to. If it appears suspicious or doesn’t match the displayed text, avoid clicking.
Enable email security features: Utilize spam filters and email security software to automatically detect and block suspicious emails.
Educate employees: Train your employees on cyber awareness and safe email practices to minimize organizational risk.
Keep software updated: Regularly update your operating system, applications, and antivirus software to patch vulnerabilities that hackers might exploit.

Remember:

When it comes to unfamiliar files in your inbox, err on the side of caution. It’s far better to delete a suspicious email than risk the consequences of opening a malicious file.

By understanding the dangers and implementing these essential steps, you can navigate the digital world with confidence, protecting yourself and your organization from the ever-evolving threats lurking within unsuspecting files.
