I recently received an automatic reply to an email indicating that the recipient was on holiday and giving his cellphone/mobile number so that he could be contacted while away. The email was from a home computer, which could perhaps be deduced from the lack of an associated job description.
The person would seem to be confirming to spammers that they've hit a working email address. But my main concern was that he may be risking burglary. However, I do not understand enough to know how this might realistically happen or gauge the risk involved.
People do reveal their addresses in social media and there are online directories where this information can be found. Also data breaches may lead to addresses and associated emails being placed on the dark web.
So does such information offer ways in which a returned spam message could be linked up to someone's home address? I appreciate that someone could be targeted by an individual but is there also a risk that criminals could harvest these associations automatically?
I appreciate that a similar question has already been asked, but the question about how one's home address could be determined was not answered.
Question changed from “How dangerous are automatic-reply emails which indicate that you are on holiday?” as this was judged to be asking for opinions rather than knowledge-based answers.
That such emails could be used to rob you is claimed in this article from Lifewire, though there would appear to be no explanation of how your home address could be determined.
My concern is that a program which interrogated the returns from spam (along with email / home address associations) could then produce lists of potentially vacant homes. Such information might then be sold to potential burglars. Is such a scenario possible?
