The cryptocurrency industry and those responsible for securing it are still in shock after the robbery of Friday, probably by North Korea, who struck $ 1.5 billion from the Exchange Bybit established in Dubai, so that the theft is by far the The biggest ever in the history of digital assets is.
Bybit officials revealed the theft of more than 400,000 Ethereum and set out Ethereum coins just a few hours after it took place. The report said that the digital loot was stored in a “multisig cold wallet” when it was somehow transferred to one of the hot portfolios of the exchange. From there, the cryptocurrency was completely transferred from Bybit and controlled in portfolios by the unknown attackers.

Researchers for Blockchain -analyzed company Elliptic said, among other things, on the weekend that the techniques and the flow of the subsequent money laundering of the funds bear the signature of threat factors that work on behalf of Noord -Korea.

Wallets are accounts that use a strong coding to store Bitcoin, Ethereum or another form of cryptocurrency. These portfolios are often accessible online, making them useful for sending or receiving funds from other portfolios on the internet. In the past decade, these so -called hot portfolios have been removed from digital coins that are supposedly worth billions, if not trillions, of dollars. Usually these attacks arose from the thieves who somehow have obtained the private key and empty the wallet before the owner even knows that the key has been affected.
