The Wallet Inspectors: The DPRK’s Sophisticated Campaign to Steal Cryptocurrency and How to Protect Yourself

On February 21, 2025, Bybit, one of the world’s largest cryptocurrency exchanges, suffered a cyberattack resulting in the theft of approximately $1.5 billion in Ethereum tokens. This attack marked a new pinnacle in the criminal efforts of cyber actors tied to the Democratic People’s Republic of Korea (“North Korea” or the “DPRK”). In recent years, these malicious actors have increasingly targeted the cryptocurrency industry, leveraging sophisticated tactics to steal and launder digital assets for the ultimate benefit of funding the North Korean government. These high-profile and high-dollar-value exploits underscore the ongoing risk from the DPRK cyber threat and the need for private sector actors to implement appropriate cybersecurity measures to combat these threats. The threat is particularly acute since most interactions with these actors raise the additional risk of committing a violation of U.S. sanctions, with corresponding civil and criminal legal exposure.

This blog post delves into the details of recent cybercriminal activity attributed to actors tied to North Korea, their impact on the cryptocurrency sector, and the steps organizations should consider to mitigate those risks.
