Protect Yourself from Phishing and Malware Attacks

Understanding Phishing

Email Deception: Phishing schemes utilize deceptive emails, often appearing genuine, to trick recipients into opening attachments or clicking on links.

Phishing Attachments

Disguised Content: Phishing emails may contain attachments disguised as invoices or delivery notices, often created with Microsoft Word or Excel, containing malicious "Macros" that download malware upon execution.

Link-Based Phishing

Exploitative Links: Clicking on links in phishing emails can lead to seemingly legitimate websites exploiting computer vulnerabilities or tricking users into disclosing personal information.

Targeted Attacks
