The well-known manufacturer of hardware cryptowallets Ledger announced a partnership with Intel.

According to the press release, the companies will work on integrating the BOLOS operating system (Blockchain Open Ledger Operating System) used in the Ledger wallets into the Intel product line, where Software Guard Extensions (SGX) technology is used.

We have seen an increasing demand from the market for secure solutions to manage crypto assets over the past couple of years. Following the launch of a line of hardware wallets based on our operating system integrated in a secure chip, working with a leading player like Intel is a unique opportunity to keep providing our growing client base with innovative solutions for cryptocurrency and blockchain applications.
 

Eric Larchevêque

CEO, Ledger

The new development will be integrated into popular software cryptowallets, including Electrum and MyEtherWallet. The solution from Intel will protect important data from unauthorized use with the so-called SGX-enclaves, which, in particular, will store private keys and sign transactions. 

Ledger to Discover HSM Vulnerability

HSM is an external device designed to store public and private keys used to generate digital signatures and to encrypt data, used by banks, exchanges, etc

A group of researchers from Ledger identified several vulnerabilities in the Hardware Security Module (HSM) devices, which can be used to extract keys or perform a remote attack to replace the firmware of an HSM device. The problem report is currently available only in French, the English-language report is scheduled to be published in August during the Blackhat USA 2019 conference. HSM is a specialized external device designed to store public and private keys used to generate digital signatures and to encrypt data.

HSM allows you to significantly increase protection, as it completely isolates keys from the system and applications, only by providing an API to perform basic cryptographic primitives implemented on the device side. Typically, HSM is used in areas where you need to provide the highest protection, for example, in banks, cryptocurrency exchanges, certification centers for checking and generating certificates and digital signatures.

The proposed attack methods allow an unauthenticated user to gain complete control over the contents of the HSM, including extracting all the cryptographic keys and administrative credentials stored on the device. The problems are caused by a buffer overflow in the internal PKCS # 11 command handler and an error in the implementation of the cryptographic protection of the firmware, which bypasses the firmware check using the PKCS # 1v1.5 digital signature and initiates loading the own firmware in the HSM.

The name of the manufacturer, the HSM devices of which have vulnerabilities, has not yet been disclosed, but it is argued that the problem devices are used by some large banks and cloud service providers. At the same time it is reported that information about the problems was previously sent to the manufacturer and it has already eliminated vulnerabilities in the fresh firmware update. Independent researchers suggest that the problem may be in the devices of the company Gemalto, which in May released an update to Sentinel LDK with the elimination of vulnerabilities, access to information about which is still closed.
