On Monday, July 9, the release of new software for hardware bitcoin wallets Ledger Nano S and Ledger Blue under the name Ledger Live with support for Windows, Mac and Linux operating systems.

According to the developers, Ledger Live is a complex application that combines the functions of managing a hardware device and digital assets. The new software has replaced many browser extensions based on Chromium.

Installing a new device and connecting an existing account to Ledger Live takes place as quickly as possible. Simultaneously, all crypto-currencies are now available in one account, which eliminates the need for users to use different applications for Bitcoin, Ethereum or Ripple.

It is noteworthy that the user interface provides data on the cost of all crypto assets in real time, and also displays the status of transactions.

The first version of Ledger Live does not support ERC-20 tokens, but the developers have already promised to add this option in the next releases.

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
10 June 2019   1493

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.
