Flag Finding in Penetration Test

Need a bit of help in reagards to flag finding.

I have gained access to a custom Target mahine on VMware to find 3 flags.

all the flags start with word “flag” and some of them are encrypted. I could only find 1 broken link to 1 flag but when i try to open it, it just prints out some weired data. Could anyone please guide me how to:

  1. open the contents of this found flag.

  2. how to find other 2 flags.

Thanks
