EDIT: Use gimp to save it as ASCII portable bitmap (https://en.wikipedia.org/wiki/Netpbm_format), strip the headers and all the junk and you get a message that links to mi5.gov.uk/careers.

So i doubt there is much more to it ;)
Uncompressed it's just a binary message of 2 pixel colours, so unless that comment at the end is pointing somewhere else then it's not got much depth...
