I picked the filename condition from a sample rule on a web site with a number of yara rules.
Too bad I didn't bookmark it...

Will try to find it again.

filename does not appear as a yara keyword:

Is it a new keyword not yet in a released version of yara? Did you mean
filesize?

Guys,

clamscan --database=test.yar blah.html
LibClamAV Error: yyerror(): test.yar line 6 undefined identifier
"filename"
LibClamAV Error: cli_loadyara: failed to parse rules file test.yar, error
count 1
test.yar: OK
blah.html: OK

test.yar
rule TEST_BLAH_FILENAME
{
    strings:
        $BLAH = "blah"
         condition:
         $BLAH and filename == "blah.html"
}

Am I missing something? or is filename unsupported by ClamAV's YARA engine?

Thanks!
