Continuing my diary entries on Sysinternals tools with VirusTotal support, I'm taking a look at sigcheck.
Sigcheck is a command-line utility to check the digital signature of files like PE files (EXEs).
Sigcheck also supports VirusTotal searches. When you use option -v, the hash of the file will be submitted to VirusTotal. The first time you run it, you'll have to accept VirusTotal's terms (or use option -vt to accept and avoid the prompt):
You'll get the score and a link to the report for the checked file.
If a hash is not present in VirusTotal's database, the file will not be submitted, unless you use option -vs:
You can scan a complete disk with option -s and specifying the root folder of the disk (e.g. c:\), and you can produce a CSV report with option -c:
As can be seen from this last screenshot, files without digital signature are also checked with VirusTotal.
