I am curious about infections via email and how likely it would be possible to get infected through just opening an email, in various situations.
I have been reading about people talking about 1x1 pixel images that could contain malware, or be a tracking pixel, as well as images in general containing malware, so I'm curious if it's possible to get malware from an included image in an email?
Since a lot of sites are using HTML markup, as well as images in email to be fancy, I am curious about those being used as attack vectors? I would assume email clients would put in protections for us users against this? From what I have read, email clients usually protect against execution of JS and other code in the email client, but I am curious about images, and how that plays a role if there is malicious code embedded, compared to just a script executing?
I am also curious about the possibility of infection if one were to use the option of "View Source" which I saw as an answer to this question.
It seems that in the "View Source" case we are just given a bunch of text, and the only way that we could be attacked is if there was a vulnerability in the actual viewing source mechanism which would execute malicious code?
I also post the above link because it is similar to my question, but it is older, and possibly lacking in new knowledge of vulnerabilities and such that have been found in the last bunch of years.
