always safe as long as I open it with trusted software?

00:00:14

False.

00:00:14

Even if the site or sender seems reliable,

00:00:17

it might have been hacked or the file could have been altered en route.

00:00:20

And trusted software does not necessarily prevent the opening of a malicious file.

00:00:24

Some files exploit vulnerabilities in the programs themselves.

00:00:28

One must always verify the source and context.

00:00:31

Word and Excel files can contain malicious macros

00:00:34

that activate as soon as I open them,

00:00:36

even if I am careful.

00:00:38

True,

00:00:39

macros are small scripts that can automate actions or install a virus.

00:00:43

In some cases,

00:00:44

opening a file can be enough if the macros are automatically activated.

00:00:48

Fortunately,

00:00:49

recent software blocks macros by default,

00:00:52

but it's best never to activate them if you don't know their origin.

00:00:56

Is a PDF file always secure if it comes from a reliable source?

00:01:00

False.

00:01:01

PDF files can also contain malicious code or be

00:01:04

designed to exploit vulnerabilities in your PDF reader.

00:01:07

Even a PDF can trap you,

00:01:08

especially if it comes from a hacked contact or contains links or attachments.

00:01:12

The format is not a security guarantee,

00:01:14

so no,

00:01:15

a file is never completely harmless.

00:01:17

Even if it looks legitimate,

00:01:18

it can contain an unpleasant surprise.
