North Korean hacking groups, notably Lazarus, executed significant cryptocurrency heists through spear phishing tactics in 2025, targeting exchanges and wallets globally, raising cybersecurity concerns.
These cyber attacks highlight vulnerabilities in digital asset security, affecting market trust and prompting regulatory scrutiny, while demonstrating rising sophistication in state-sponsored cybercrime.
Lazarus Group Orchestrates $1.5 Billion Bybit Heist
North Korean hacking groups, notably the Lazarus Group, were involved in spear phishing campaigns. They have executed crypto-related attacks to fund military programs. These operations focus on cryptocurrency exchanges and personnel within the crypto sector.
Lazarus Group led major attacks including a $1.5 billion heist at Bybit exchange. They used techniques like spear phishing to target key individuals and steal crypto assets. The targeted institutions and crypto entities are adapting future security measures.
North Korea’s Hacks Steal $2.84 Billion in 2025
The financial impact from North Korean hacking activities has resulted in approximately $2.84 billion stolen in 2025 alone. This activity significantly affects both Bitcoin and Ethereum markets, with funds often laundered through mixers.
US authorities and cybersecurity experts strive to counter North Korean tactics. Sanctions are imposed and ongoing monitoring continues, although the threat remains due to the groups’ evolving strategies. “We have imposed sanctions targeting North Korean actors tied to cyber fraud and financial theft to curb funding of weapons programs.” US Department of Treasury, Government Body Assets are seized to mitigate the financial damage.
Consistent Use of MFA Bypass in Cyber Attacks
Similar cyber-thefts by the Lazarus Group have occurred over the years. The use of spear phishing combined with MFA bypass techniques remain consistent, as evidenced in past attacks on cryptocurrency exchanges.
Cybersecurity experts highlight the rising risk of generative AI in spear phishing. Oliver Smith from GitLab noted, “The expansion of spear phishing is targeting trader and marketing roles within crypto sectors.” Preventative measures are imperative to thwart future hacks.
