Understanding the Risks of Suspicious Attachments
Receiving a suspicious email attachment can be alarming, especially with the increase in sophisticated phishing and malware attacks. Suspicious attachments are often used by cybercriminals to gain access to your personal information or infect your device with harmful software. This section explains what suspicious attachments are, why they are dangerous, and the types of malware commonly delivered via attachments.
Cybercriminals often disguise attachments to appear legitimate, such as invoices, scanned documents, or purchase orders. Below are some common threats that may come with these attachments:
- Malware: Harmful software like viruses, trojans, and spyware.
- Ransomware: Encrypts files on your computer and demands payment for access.
- Keyloggers: Programs that record keystrokes to steal passwords and personal information.
It’s essential to recognize and avoid these attachments before opening them. Understanding the risks can help you make safer decisions when dealing with unknown emails.
