    Can malware infect from inside PST file?


    As part of backing up an Outlook.com email address, I want to ask Microsoft to generate a PST file for the whole mailbox that I can download. However the mailbox is large and is getting spammed quite a bit, so I'm assuming that there will be some emails mixed in that contain malware inside them. This makes me wonder how I am going to handle the PST file, as I am concerned that just downloading it onto my PC might allow any malware to infect the computer from inside the PST file - even if I don't try to open it. Should I be worrying about this, or is the PST file safe?

    :)

    Outlook PST File Problem

    That is exactly what I was going to suggest. Export everything to another PST file, delete the old(or rather move it out of the default folder) and replace it with the new PST file that you exported.

  3. Can a .PST File Get Hacked or Become Infected?

    Malwares are doing a lot of tricks, one common form used to be .JPEG file that has been infected and virus embedded into it in past. So it is not about the file extension but you have to prepare to protect any type of file. There aren't many cases about
    infecting and hacking .pst files but anything could be happen in future , so you should follow general best practices with security and if you see any suspicious sample, make sure submit it for analysis. If those file are not password protect, they could be
    open using any outlook app and password for the file must be strong so it won't be broken. If you have Bitlocker in system, it encrypt everything including .pst file.

    Can a .PST File Get Hacked or Become Infected?

    With Cyber security month almost at its end, we're still reviewing where potential holes might be, generally. One question came up about Outlook PST files. I'm mainly referring to the files on standalone PCs that are not connected to Exchange Server.

    Are there any known occurrences of someone stealing data out of a PST file? Can they be hacked?

    Can they become infected? If so, if you get a virus and have multiple PST files, does it just infect one, or can it infect all?

    Just thinking
