    Odd Regular expressions

    jtoto_2002

      I've got a couple signatures that have some odd regex in it.

       

      \x30#F0

      and

      \x60#E0

       

      Through testing I've found that "\x30#F0" will alert with anything between HEX value \x30 and \x3F.  "\x60#E0" will alert with anything between HEX value \x60 and \x7F.

       

      So my question is, what are the "#F0" and "#E0" expressions actually telling it to do?

       

      Thanks!
