Version Summary:IntelliShield has updated the alert to include more specific information regarding reports of the badBIOS malware activity.
 

Description
 
A security researcher has reported that badBIOS is multiplatform malware that could infect the firmware or system BIOS of systems running Windows, Linux, or Mac operating systems.

The malware has been reported to infect system firmware by overwriting part of the system BIOS with malicious code. Because the malicious software resides in the system BIOS, the malware could continue to infect the machine even after system reinstallation.

The malicious software in the BIOS could access system files or prevent access to system resources such as system settings, device drivers, processes, or data on the system. The malicious software may also use covert network traffic to connect to remote hosts on the Internet using IPv4 or IPv6 protocols. The security researcher also reports that infected systems disconnected from all network connections could communicate wirelessly with each other through ultrasonic sounds using the system speakers and microphones.

Active infections of the malware have been observed in the wild. The malware may be spread through USB drives when an infected drive is injected physically to a system. It is unknown whether the malware could spread through the network.

Independent confirmation or samples of the malicious software are not available.

Considering the level of execution complexity and capability of the malicious software, badBIOS could be part of an Advanced Persistent Threat (APT) attack targeted at environments that use multiple different system platforms with the intention to access sensitive information.

Administrators are advised to allow only trusted users to access local systems.
