Kaspersky Researchers have discovered CosmicStrand rootkit in modified Unified Extensible Firmware Interface or UEFI. This firmware malware loads up on your PC when it starts and then initiates the OS boot process. This is something that loads up before the operating system boots up, and the criticality of this issue can also be magnified by the fact that this malware does not load from your hard disk but a chip on the motherboard. In other words, malware is so powerful that if infected, you need to discard your PC hardware into the trash.
The Threat Posed By UEFI Malware
UEFI firmware is resistant to any hard drive manipulations since it is integrated into a chip on the motherboard and not written to the hard drive. As a result, it is exceedingly challenging to remove UEFI-based malware; even erasing the drive and installing the OS again won’t work on UEFI. For the same reason, not all security programs are capable of finding malware buried in UEFI. Simply, once malware has entered the firmware, it will remain there.
Of course, hacking UEFI is not a straightforward task: either proximity to the device is required, or another advanced method of remote firmware malware infection is used. Additionally, the virus must enter the operating system at startup and reside in UEFI to accomplish its final objective, whatever that may be. This takes a lot of work, which is why targeted assaults on well-known people or organizations are the context in which such malware is most frequently used.
CosmicStrand’s primary function is to download a malicious application at an operating system startup, which subsequently carries out the attackers’ specified activities. The OS boot process is completed by the firmware rootkit, which then executes shell code, makes contact with the attackers’ C2 server, and gets a malicious payload. The firmware rootkit received a file from its C2 server, but the researchers could not intercept it.
Instead, they discovered a piece of malware on one of the compromised computers that were probably connected to CosmicStrand. The operating system’s “aaaabbbb” user is created by this virus and given local administrator privileges.
