in reply to Malicious Perl Scripts & Web Development
As long as there isn't any personal or corporate information included in the script it should be fine to paste it here. You could add a warning that it's potentially malicious and include it inside code tags like this: <code> ... </code>. Since you posted anonymously you can't edit your node and you'll have to post it in a new one.
If it is obfuscated it might be difficult to tell what it contains. In that case you could use Perl's B::Deparse module to deparse it and get an idea of what the script would do without actually running it. Here are some examples: Debunk Perl's magic with B::Deparse, 804232
Try this:perl -MO=Deparse byyl.pl
