Couple of pre-coffee questions...

1)

>From what I can tell Yara signature names will be generated based on
the yara rule name provided...

eg:

testname.yara:

rule Sanesecurity.test
{
strings:
$match1 = "test"
$ignore1 = "this1"
$ignore2 = "this2"
condition:
$match1 and not ($ignore1 or $ignore2)
}

So, if it matched the name will be: Sanesecurity.test.UNOFFICIAL

Would it be a good idea if ClamAV engine *auto-added* .Yara or _Yara to the
end/beginning of Yara signatures to help end-users work out if it's a
normal ClamAV database or a Yara rule:

Eg: Sanesecurity.test.Yara.UNOFFICIAL

2) I take it Yara signatures can be whitelisted using .ign2 etc.


Cheers,

Steve
