4 Answers. Show activity on this post. As for how it may happen that reflashing the BIOS does not eradicate the malware, we can hazard a few guesses: The reflash operation is under control of… the BIOS, so the infected BIOS only pretends to do the reflash (or reinfects the new BIOS immediately afterwards).
Can ransomware affect the BIOS?
Yes, the BIOS is software. If it is writeable/flashable, it is possible for the BIOS to be overwritten or modified such that it performs malicious actions. The BIOS boots before the operating system and bootloader, so it is entirely possible for BIOS malware to impact and infect on each boot or on fresh installs.
