CertiK’s analysis attributes a large share of 2025 cryptocurrency theft losses to North Korea-linked state-sponsored hacking groups. The report estimates that these attackers steal roughly $2.1 billion out of about $3.4 billion in total losses from crypto hacks during the year, meaning they account for around 60% of all identified losses. The sources say the attackers increasingly use sophisticated laundering methods, including cross-chain activity, to move stolen funds through multiple blockchain networks. One outlet also describes a shift in tactics, portraying the activity as becoming more “industrialized,” with groups moving beyond traditional approaches such as phishing toward additional methods that can include physical infiltration. Across the reporting, the common focus is that crypto crime in 2025 is increasingly dominated by state-linked actors and that stolen funds are laundered at scale. Both outlets reference the same CertiK findings, though they differ slightly in the exact dollar figures cited for total losses.
