Malicious Spyware infects firmware

Your information is on more than one network and if someone wants it bad enough, like from Anthem or your Bank for example, they can get it. And they don't need it because they are trying to do you any favors.

Be aware that anything on a network is vulnerable and there is an arms race to protect it whether you are participating in it or not.

"Kaspersky Lab says the malicious spyware ... implants are different from other cyberattacks in that they directly infect a computer’s firmware — the software that links directly to the hard drive.
This means that it is beyond the reach of most antivirus and security products, and is immune to efforts to wipe clean or even replace hard drives since it can be recalled at will."
