The FBI has issued a warning about North Korean hackers aggressively targeting the cryptocurrency industry. These cyber actors are executing sophisticated and hard-to-detect social engineering schemes to infiltrate companies associated with decentralized finance (DeFi) and cryptocurrency exchange-traded funds (ETFs). The hackers are using fake job offers and investment deals to lure employees into downloading malware, which allows them to steal digital assets, including Bitcoin and Ethereum. The FBI advises firms to strengthen their security measures to protect against these threats. Millions have already been stolen in these attacks, highlighting the vulnerability of Web3 infrastructure.
