Need help!

[welchy]

I have a very important question for the Calguns brain trust. Is it possible to go change email attachments after they have been sent and even forwarded? I am involved in a nondisclosure real estate law suite and it appears that someone did just that. Thank you in advance for your help.

Not sure what you're asking.... but I'll give it a shot.

If you're asking if an email attachment can be changed/ modified by the recipient, then yes- depending on what type of file is attached and/ or if the document was protected from being modified (password protected etc).

If you're asking if the sender can change an email attachment after it's sent, then no, they can't.

I am asking if anyone other than the recipient can change an attachment after it is sent.

Thank you for you response.

This.

And even if it's protected from being modified, you can "Save As" and save it to another name and then you can modify it.

Anything that has already been sent is gone.

Maybe getting into tinfoil hat territory but if the recipients email address is provided by a company and is managed by a company IT department, I would guess they could access company emails.... just a guess though.

But if it's a general @yahoo, @gmail etc, and the recipient is the only one with the email credentials, then, generally speaking, no one can access the emails and therefore, could not change an attachment.

If the attachment is a document type that executes code and loads external resources, potentially, PDF, HTML, XML, DOC, XLS, etc, then it is perfectly plausible that the contents will change depending on what the embedded scripts are actually fetching.

If that is the case and you allow executable documents, you will eventually get burned with a trojan or virus and should immediately stop letting attachments execute.

That’s one of the reasons that when I work with my lawyer on shared documents, it’s on their private Dropbox account so we can both audit versions and never have to attach anything other than the URL to the latest version of the document.

They are all PDF files. My wife and I specifically remember 2 documents as being completely different when we first received them.

No one is changing the attachment after it is in your mailbox, short of an admin of your email system.

Yes there could be dynamic content, or date based macros or who knows what, that change what you see even though the attachment has not changed.

You could download the original attachment, then shut off your internet access and roll back the system clock before opening the attachment, and see what you see then...

If you received them, you probably still have those copies on your computer somewhere (perhaps a temporary file somewhere?). You could compare them to whichever documents now seem to be different.

[welchy]

Is there a way that I can keep them from being changed from their current form?

It has been almost 2 years.

Depending on your email provider and if you do maintenance or have a lot of storage, check your sent folder. Do a search. You may get lucky. 2 years is a lot of emails.

The attachment is probably a link to a cloud source which can be edited at will, usually, as long as you have access.

Otherwise, an Exchange server allows you to do some alterations or recalls on emails that were already sent as long as all the recipients are on that server. If you are forwarding something to another domain and it is altered then its probably a link and not an actual file attachment. Every real estate thing I've done with email uses docusign or something similar which means the "attachment" you have is just a link to their cloud service.
