flash BIOS because of Massive Hack

HP Recommended
510-p024

Pavilion and my wife's HP laptop were badly hacked around four nights ago. I use a debian  variation, which now fails often and needs to be reinstalled. It always worked well before this. Now, at best, the machine is slow, and copies everything into hidden (dot) files to be used for some purpose.  At worst, the boot ends at a grub prompt. It goes between several grubs, in different locations. 

     The best part of this:

CHECKING the BIOS shows an unknown copy of Ubuntu somewhere in the BIOS, which may mean EUFI, or whatever you put an abbreviated version of Ubuntu into. It appears as a boot option which I deselect, and which comes back.  My reaction was to flash the bios but I can find no file on you system to do so. It would have to be flashed from this computer, as my wife's  HP Laptop was destroyed, its registries  left in pieces. 

     I remember a USB stick flash  but cannot find it. BIOS Revision 81B4 vF .04.   BiIOS date 05/10/2016  CPU  i7-6700T

Despite what you see, there is no Linux code in the BIOS -- that only contains firmware.

 

To update BIOS code, the hack would have had to write into the firmware, which I serious doubt it could have done.

 

There are entries in the various boot records, which are different between  BIOS and UEFI, and if those get corrupted, you will have serious problems booting -- but these are unrelated to the BIOS code.

 

Unfortunately, we do not support Linux on this forum so your best bet is to go here: https://ubuntuforums.org/

Good Luck
