Trezor bitcoin wallet was hacked in 15 minutes, Twitter added Bitcoin emoji, and 5 Chinese pools control 50% of the bitcoin network

Kraken experts hacked Trezor bitcoin wallet in 15 minutes

Kraken security experts managed to extract the SEED phrase from the Trezor hardware wallet — it took them 15 minutes to do this.

To make a similar attack, an attacker needs physical access to a Trezor One or Trezor Model T wallet, as well as an inexpensive device that can cause a voltage glitch. Such device that can be bought for about $75.

“The attack takes advantage of inherent flaws within the microcontroller used in the Trezor wallets. This unfortunately means that it is difficult for the Trezor team to do anything about this vulnerability without a hardware redesign.”

It’s a flaw that’s present in the hardware, not something they can just put a formal update on and fix it for all their customers. To address this problem, they would essentially need to put out a new device,” said Nick Percoco, director of security at Kraken.

Trezor said that the attack cannot happen remotely, and it will not work if users turn on the BIP 39 passphrase. Earlier, Kraken specialists found a similar vulnerability in KeepKey wallets.

Twitter added bitcoin emojis

Binance CEO Changpeng Zhao, Tron founder Justin Sun, and Morgan Creek Digital co-founder Anthony Pompliano mae tweets with the BTC emoji.
