Handle email attachments safely

Attachments are a common way malware gets in. A moment’s caution beats a ransomware clean-up.

1. Only open attachments you were expecting from someone you know — verify first if anything seems off.
2. Be most wary of .zip, .html, .iso and Office files that prompt you to enable macros or enable content.
3. Don’t trust the file icon — a document icon can hide a program; check the real file extension.
4. Hover over the sender’s address to confirm it’s genuinely who it claims to be.
5. If a known contact sends an unexpected file, confirm with them by phone or chat before opening it.
6. When unsure, save nothing and forward the email to your IT team to check.
