![]() As a PC user there is not much you can do about this incident, but be prudent. They are likely from sources that are trying to trick you into installing malware. Update from vendor websitesĪlthough no attacks of this kind have been found in the wild and Binarly, after a lengthy and detailed analysis, states that “the leaked Boot Guard keys are intended for debug building lines and most likely we will never see such devices in the wild,” the advice to obtain firmware/BIOS updates only from official vendor’s websites is solid.Īlso watch out for phishing emails claiming that you need new firmware for whatever reason. Among them are household names like Lenovo and HP. Secure Boot is an option in UEFI that allows you to make sure that your PC boots using only software that is trusted by the PC manufacturer.īinarly compiled a list of 57 MSI PC systems which have had firmware keys leaked, and 166 systems which have had Intel Boot Guard BPM/KM keys leaked. Boot Guard is a key element of hardware-based boot integrity that meets the Microsoft Windows requirements for UEFI Secure Boot. Intel Boot Guard is a hardware-based technology intended to protect personal computers against executing fake UEFI (Unified Extensible Firmware Interface) firmware.Ī bypass could provide an attacker with full access to a system, access secure data or use it for any number of malicious purposes. Having the signing keys potentially allows an attacker to create fake firmware updates that would bypass Intel Boot Guard. The leaked data includes private keys, some of which appear to be Intel Boot Guard keys. Researchers are now starting to unravel the significance of the stolen data. When the $4 million ransom demand was not met, Money Message began leaking the MSI data on its data leak site.Īccording to BleepingComputer, a Money Message operator said in a chat with an MSI agent: “Say your manager, that we have MSI source code, including framework to develop bios, also we have private keys able to sign in any custom module of those BIOS and install it on PC with this bios.” The Money Message gang claimed to have stolen 1.5TB of data during the attack, including firmware, source code, and databases. In April, criminals used Money Message to hit at least 10 victims, mostly in the US, and from various industries, including MSI. Money Message is a new ransomware which targets both Windows and Linux systems. While the statement does not reveal a lot of tangible information, this snippet is important: “MSI urges users to obtain firmware/BIOS updates only from its official website, and not to use files from sources other than the official website.”Īs we mentioned in our May ransomware review, Taiwanese PC parts maker MSI fell victim to ransomware gang Money Message. On ApMSI (Micro-Star International) released a statement confirming a cyberattack on part of its information systems.
