Hacked Pklite File Scanning
---------------------------

In issue two, i belive it was. I release a method of making Pklite
files un-uncompressable and un-detectable. Well seems a few people
used the trick for wrong doing. What do I mean by wrong doing you
ask? Well lets just say lame trojans and such.

Anyway, I had a few sysops on my ass about the trick and so, so now I
am must release.... The hacked Pklite scanning strings. Well I
could really give a fuck if someones BBS gets crashed, but then again
I am freinds with a lot of sysops. And besides I have a new trick
anyway :)

Well there are two strings. One for .EXE files and one for .COM
files. And here they are.

-----------------------------------------------------------------------

"01 F0 FF 50 00 00 00 03 01" Pklite EXE
"53 33 DB 53 CB 03 01" Pklite COM

------------------------------------------------------------------------

What's my new trick??? Well I won't reveal it at this point... But here
is a another compression trick. It lets you compress a file with Pklite
then again with LZExe.

First
-----

Compress the file with Pklite

Next
----

Compress the file with LZExe

It wont let you cause the file becomes bigger...

But
---

Use the DOS Undelete function to undelete the file ?zexe.tmp. Thats the
twice compressed file. Rename it to what you want. Destroy the LZ
header... And there you have it...
