Got out my nt password bootable usb for this job & found out the scammers/ransomwarers had put a password on boot (not the windows password) (So it aint getting me anyware). I cannot get to bios etc to reset boot sequence (No F keys work).
Asus notebook
 
Its a simple DOS looking password box that gives you 3 goes & then try again.
 
Mongrels.
I can pull the hdd & slave it, but the issue may be in the bios on the MB. Cannot see the cmos battery!
 
Any tips out there?

Further to this issue, I have since taken every screw out of laptop & located the cmos battery.

 

After reset it then went further than the initial bios password & on to a HDD password !!!? (mongrels)

So it appears to have multi level passworded features.

Hello, what we can try is see if the MBR was somehow altered. Did you use any form of drive encryption on the disk?

Try this please. You will need a USB drive.

Download GETxPUD.exe to the desktop of your clean computer
  • Run GETxPUD.exe
  • A new folder will appear on the desktop.
  • Open the GETxPUD folder and click on the get&burn.bat
  • The program will download xpud_0.9.2.iso, and upon finished will open BurnCDCC ready to burn the image.
  • Click on Start and follow the prompts to burn the image to a CD.
  • Remove the USB & CD and insert it in the sick computer
  • Boot the Sick computer with the CD you just burned
  • The computer must be set to boot from the CD
  • Gently tap F12 and choose to boot from the CD
  • Follow the prompts
  • A Welcome to xPUD screen will appear
  • Press File
  • Expand mnt
  • sda1,2...usually corresponds to your HDD
  • sdb1 is likely your USB
  • Click on the folder that represents your USB drive (sdb1 ?)
  • Press Tool at the top
  • Choose Open Terminal
  • Type the following and press enter:

    dd if=/dev/sda of=mbr.bin bs=512 count=1
  • Press Enter
  • After it has finished a file will be located on your USB drive named mbr.bin
  • Remove the USB drive and insert it back in your working computer and navigate to mbr.bin, zip it up and attach it to your next reply.
This will allow me to have a look at the MasterBootRecord of your drive and see if it is infected.

regards, Elise
