To Two … Infecting the UEFI on a motherboard is no small task thankfully, as you need physical access to hack the flash chip on the motherboard to implement a hack, there is no known way to do this remotely.
For only the second time in the annals of cybersecurity, researchers have found real-world malware lurking in the UEFI, the low-level and highly opaque firmware required to boot up nearly every modern computer. About The Author. Jeremy Hellstrom Call it K7M. Related Posts.
The Windows 10 kernel, in turn, verifies every other component of the Windows startup process, including the boot drivers, startup files, and ELAM.
If a file has been modified, the bootloader detects the problem and refuses to load the corrupted componen t. Because traditional malware apps do not start until the boot drivers have been loaded thereby giving rootkits disguised as drivers to work. ELAM can load a Microsoft or non-Microsoft anti-malware driver before all non-Microsoft boot drivers and applications, thus continuing the chain of trust established by Secure Boot and Trusted Boot.
Measured Boot : Most antimalware software are extremely very good at detecting runtime malware , attackers are also becoming smarter at creating rootkits that can hide from detection as well. Detecting malware that starts early in the boot cycle is a challenge that most antimalware vendors address diligently. Typically, they create system hacks that are not supported by the host operating system and can actually result in placing the computer in an unstable state.
Up to this point, Windows has not provided a good way for antimalware to detect and resolve these early boot threats. Starting from Windows 8, a new feature was introduces called "Measured Boot", which measures each component, from the firmware up through the boot start drivers, stores those measurements in the Trusted Platform Module TPM on the machine, and then makes available a log that can be tested remotely to verify the boot state of the client. Working with the TPM and non-Microsoft software, Measured Boot in Windows 10 allows a trusted server on the network to verify the integrity of the Windows startup process.
The trusted attestation server sends the client a unique key. In summary, the Measured Boot feature then provides antimalware apps with a trusted resistant to spoofing and tampering log of all boot components that started before the antimalware software. Antimalware software uses this log to determine whether components that were initiated before it are trustworthy or if they are infected with malware in the following ways discussed below.
Depending on the implementation and configuration, the server can now determine whether the client is healthy and grant the client access to either a limited quarantine network or to the full network. In your environment, the system administrator has control of how Measured Boot information is used. In end-user scenarios, for example, online banking , the consumer must opt in to use Measured Boot for the specific service. I hope you found this blog post helpful.
