BlackLotus UEFI Bootkit: A New Threat to Windows Security


In March 2023, security researchers from ESET announced the discovery of a new UEFI bootkit called BlackLotus. This bootkit is capable of bypassing UEFI Secure Boot, a security feature that is designed to prevent malware from infecting a computer's firmware. Once BlackLotus is installed, it can give an attacker complete control over the computer, including the ability to steal data, install other malware, and disrupt the computer's operation.

BlackLotus is a sophisticated piece of malware that is difficult to detect and remove. It is also relatively new, so there is limited information about how it works. However, ESET researchers have been able to learn a lot about BlackLotus, and they have published a detailed analysis of the malware.

According to ESET, BlackLotus is a modular bootkit. This means that it is made up of a number of different components that can be combined in different ways. This makes it difficult for security solutions to detect and block BlackLotus, as they may not be able to detect all of the components.

BlackLotus also uses a number of techniques to evade detection. For example, it can hide itself in the computer's firmware, making it difficult for security solutions to scan for it. It can also change its behavior depending on the environment in which it is running. This makes it difficult for security solutions to detect BlackLotus even if they know what to look for.

BlackLotus is a serious threat to Windows security. It is a sophisticated piece of malware that is difficult to detect and remove. If you are a Windows user, it is important to take steps to protect yourself from BlackLotus and other UEFI bootkits.

Prilex: The Most Advanced PoS Malware with the Ability to Block Contactless Payments

Prilex is a highly advanced malware that has evolved from ATM-focused malware into a unique modular PoS malware, known to be the most advanced PoS threat seen so far. It has a unique cryptographic scheme, performs real-time patching in target software, forces protocol downgrades, manipulates cryptograms, performs GHOST transactions and performs credit card fraud. Recently, three new versions of Prilex have been discovered with the ability to block contactless payment transactions, which have become popular due to the pandemic. These new versions block NFC-based transactions and force victims to use their physical card by inserting it into the PIN pad reader, which allows the malware to capture the data coming from the transaction.
