Bios Question

How can you tell if you have a bios problem like "man in the middle " hack ?

 

You can read these guides to signs and symptoms of BIOS problems, and how to troubleshoot if you do have those signs and symptoms:

If you need further guidance you need to give the full brand name and model of the system in question and exactly what OS it is running.

 

thanks Max, not having a problem ,was just wondering about how someone could hack your 'puter with a "man in the middle" hack on the bios
without seeing any problems on your system.
again thanks.

 

As far as Malware directed at the BIOS is concerned it's still quite rare but it does happen. But how you would even know, until the system is used for nefarious reasons might not be obvious.
These articles are quite interesting:

very good reading, which os do you think is the most secure? here is a list of a few. these are TOS (trusted operating system ) some used by "big brother"

• Apple Mac OS X 10.6 (Rated EAL 3+[2])

• HP-UX 11i v3 (Rated EAL 4+)

• Some Linux distributions (Rated up to EAL 4+)

• Microsoft Windows 7 and Microsoft Server 2008 R2 (Rated EAL 4+[3])

• AIX 5L with PitBull Foundation (Rated EAL 4+[4])

• Trusted Solaris

• Trusted UNICOS 8.0 (Rated B1[5])

• XTS-400 (Rated EAL5+[6])

• IBM VM (SP, BSE, HPO, XA, ESA, etc.) with RACF

 

I don't have the knowledge to know about that. I just keep well-secured with good up to date security software including one specific to ransomware.
None of those links work by the way, at least not for me.

 

The 'links' above are part of a copy/paste from Wiki (or one of the other sites that host that same old article): https://en.wikipedia.org/wiki/Trusted_operating_system

 

thanks for the input I was just doing some "lite" reading about the man in the middle hacks and it seems someone would have to be quite informed to pull it off.
