Blockchain technology is being utilized by North Korean hackers to hide malicious crypto theft malware, posing a significant threat to the security of cryptocurrency users. The technique, known as ‘EtherHiding,’ leverages the decentralized nature of blockchain to evade detection, allowing them to steal billions in cryptocurrency from victims like Ethereum and BNB Smart Chain. This new approach has raised concerns about cybersecurity in the rapidly evolving world of cryptocurrencies. 2025 saw North Korean hackers steal over $2 billion worth of crypto assets, highlighting the escalating threat posed by this tactic. Experts warn that unless security protocols are strengthened, cryptocurrency users will face increasing vulnerability to these sophisticated cyberattacks.
