ZIP email attachment safety checklist
What to check before opening a ZIP file received by email, especially from unexpected senders.
Safe archive checklist
- Confirm the source before opening the archive.
- Check whether the file is a normal archive, an app package, or a disk image.
- Look for executable files before running anything inside.
- Keep private files local unless you fully trust the upload service.
- Use the ZIP checker or extension checker when the file behaves strangely.
What to avoid
Avoid fake download buttons, unknown upload extractors, unexpected password-protected archives, and files that ask you to disable security protections.
