17 August 2017   2307

Today, August 17th, SatoshiLabs releases a security update to TREZOR, a new firmware version — 1.5.2 — was pushed out to all users. 

This update fixes a security issue which affects all devices with firmware versions lower than 1.5.2.


The TREZOR team is not releasing a detailed description of the issue to give enough time for users to update and for other hardware wallets based on TREZOR to distribute an update. Thus, currently, this update will be marked as optional. However, a detailed report is to be published in the coming days and once it is released, the update will become mandatory in TREZOR Wallet.

Although specific technical details are unavailable, SatoshiLabs has sought to reassure users that only physical theft would present an opportunity for malicious actors to potentially compromise devices: “It is important to note that this is not a remote execution attack,” the email to customers explains.

To exploit this issue, an attacker would need physical access to a disassembled TREZOR device with uncovered electronics. It is impossible to do this without destroying the plastic case.


It continues that “coins are safe” provided devices are kept within reach of their owners.

There is no long-term access needed to copy all your secret information from Trezor using this hack; it can be done just in 15 seconds.


For more information, please, get acquainted with the full TRESOR's report.

The state-owned Brazilian National Social Development Bank intends to issue a cryptocurrency token tied to the Brazilian real. It is reported by CoinDesk.

The pilot project for the production of a token BNDES based on Ethereum will start in January next year. At first, the coin will be used to finance cultural institutions. In particular, the bank will allocate a certain number of new tokens to the local cinema agency.

As the newspaper notes, the bank conducted experiments with steyblecoin throughout 2018. The consultant of the project for the release of a new “stable coin” will be the well-known Ethereum start-up ConsenSys.

According to representatives of the bank, the issue of the BNDES coin will help restore public confidence in Brazilian state banks, which are often criticized due to corruption scandals.

Also, the bank is confident that in the future, stablecoin can be used to finance organizations and projects from various fields.

Note that recently in Brazil there has been a trend towards liberalization of the regulation of cryptoindustry. For example, in October, the Brazilian Securities Commission allowed local investment companies to invest in a cryptocurrency ecosystem through the acquisition of derivatives and shares in foreign funds. It is noteworthy that at the beginning of the year the same financial regulator announced the prohibition of both direct investment in cryptocurrency and indirect investment through intermediaries in the person of foreign companies.
