Is there a safe way to view JPG?

Recommended Posts

I received a obviously suspicious email this morning. One of my email addresses was used for both the sender and recipient. The subject line was just my name, all in lower case. It had a jpeg attachment with a size about 192K.

This obviously appears to be a ransomeware attempt, but I'd like t0 understand a few things because I get asked this by friends and clients all the time:

  1. Is there a way that the JPG can be looked at without doing harm?
  2. How does a JPG infect my machine?

Submit the file to https://www.emsisoft.com/en/support/submit

or to Virustotal  https://www.virustotal.com/ This will just check the file against about 60 engines.

I doubt very much if JUST downloading the attachment would cause harm.  Your anti-virus should kick in. Now could look at it with a hex editor and see if the magic number is correct.

Just what is the URL of the attachment?

As for 2.) I seem to remember an exploit where the default action for a file would kick in despite what the extension was. As in double clicking a exe disguised as a jpg. That must have been fixed.
