Cell phone Virus

Thank you, that is what I thought also, just trying to verify. I appreciate the quick responses.

Thanks, the phone only access’ Outlook 365 and is not physically attached to the pc. I should have mentioned that.....

If you open email with suspicious attachment form Windows PC, it may affect only the PC.
Not your Mobile phone unless you connect to your PC or access the same email from your mobile.

The only effect is the spam mails. If you have clicked to open a link in a spam mail in Windows PC, you might be listed as a human recipient and you will receive more spam emails from such spam host. But, there is anti-spam-protection from O365 and you should not worry about that.

You guys are so very, very wrong.

While it is generally unlikely that you find a lot of people skilled enough to write executable packages to do that, it is entirely possible to write programs that can run on multiple platforms while using a single executable package.  I worked on a program, long ago, that was executable on MacOS, Windows, and Unix.  That single executable package contained startup code for all 3 platforms in a single file, and not as a zip or a script, but as a native executable program on each platform.  You just had to double click on it on Mac or Windows and it will run.  On Unix, you can start it via command line.

For the phone, it may be easier than the package I described.  You just need a program that executes on Windows and connects to the attached phone to upload and trigger the malware.  These days, users get prompts on their phone for access, but many will happily click away and allow full access to their phone.  The windows side of the executable need only enough code to dump the phone malware.  It's actually quite easy on NTFS to load many different software packages into streams that are not normally visible to the average user, making the single file size appear tiny to the user, while containing a lot more data.

Especially for Android (crippled linux) phones, they can be quite easy to attack considering they're a much larger market and many people have old phones that with vulnerabilities that can't be fixed, because the vendor no longer supplies updates.

It's better if you have malware scanners on your mail server remove them before it even reaches your mailbox.  There's no need to take that chance.
