Not in the least surprising. Wouldn't be surprised if Gmail does this to..."detect phishing" (pdfs containing phish links are common). Always a plausible reason

Not in the least surprising. Wouldn't be surprised if Gmail does this to..."detect phishing" (pdfs containing phish links are common). Always a plausible reason they can use.
- supernova87a 7y agoThere's no surprise. Gmail does. If you search for a text string in Gmail, it will return emails that contain that text only in scanned images or PDFs that are in your mailbox.
- odensc 7y agoThat doesn't mean they're crawling the URLs, just that they're indexing the content of PDFs/images for your search. Which is, honestly, a pretty useful feature. Whereas Facebook is doing this without providing any value to the user.
- badrabbit 7y agoI've worked with email security appliances that will visit the pdf url when detonating the attachment in a Sandbox. Dynamic analysis helps find 0day's ,sometimes the link leads to something worse,the link many times is a url shortner too
