Security researcher Taylor Monahan has identified at least 40 decentralized finance platforms that she claims have been infiltrated by North Korean IT workers at some stage, representing a seven-year pattern of systematic infiltration of the DeFi ecosystem.
Algorand jumped 50% after a Google Quantum AI research paper highlighted the blockchain as a live example of post-quantum cryptography implementation, while warning that quantum computers could threaten Bitcoin and Ethereum's current cryptographic security.
Google researchers published findings showing quantum computers may require 20x fewer qubits than previously estimated to break elliptic curve cryptography used by Bitcoin and Ethereum. The research suggests fault-tolerant quantum machines capable of threatening crypto security could arrive by 2029-2032, accelerating industry urgency around post-quantum upgrades.
Federal prosecutors charged Jonathan Spalletta with exploiting smart contract vulnerabilities in Uranium Finance twice in April 2021, laundering funds through Tornado Cash and spending proceeds on collectibles including Pokémon cards and antique coins. He faces up to 30 years in prison.
