- Virus Name : WEED v1.5
- PayLoad.....: Files that are not the minimum size are destroyed. There is
- also a text and a vga payload this virus contains. :-)
- If the user presses any key while inside the vga mode, the
- original program will run.
-
- Virus Target: *.exe and *.com files. COMMAND.COM is avoided!
- Target OS...: Win95 exe/com and DOS exe/com
-
- Virus Info..: WEED will disable vsafe/vscan if found in memory. WEED will
- also infect files after the host has finished running. Good
- example: pkzip and pkunzip.exe. Once pkunzip.exe is infected
- any files it makes for you *.com and *.exe will become weed
- carriers. That is, before you even have access to them.
- Virus Size..: Just a tad over 5k in length. There is a catch, not all
- of the written data is actually viral :)
- Encryption..: The entire virus is encrypted. Using different routines
- (encryption/decryption) for each routine withen the virus!
- Stealth.....: infected *.exe or *.com file will not notice infection while
- in operation.
-
- Tech Details:
-
- This is the sixth generation of the WEED virus. It's a family now. :) Lots of
- improvements and changes have been made. WEED v1.5 is smaller then v1.2 or
- v1.3, but does more :) The defective critical error handler has been replaced
- with code that should work fine. It seems to work alright during testing.
- All encryption routines have had drastic changes made to them. Should ensure
- difficulty for the end user who intends to remove this virus.
- the encrypted weed message that didn't show in v1.3 does show in this version!
-
- (Why the fuck I messed that code up before is beyond me... :-()
-
- WEED is now Windows 95 aware, and will properly infect win95 exe files. :-)
- START.EXE (32 bit enhanced driver for win95 apps) and COMMAND.COM are not in
- any way touched by WEED. Those files are left alone!
-
- WEED is quite capable of staying withen a system for a very long period of
- time. The new critical error handler has proven very effective in a variety
- of testing. WEED is novell aware, and will easily infect an entire Novell
- Network.
-
- there are no current plans to release the source to this virus. If you want to
- see how it works that badly, test your skills at debugging it.
