In a notable shift for the cryptocurrency landscape, total losses from hacks fell sharply to $76 million in December 2025, according to data from PeckShield. This represents a significant 60% decrease from the previous month”s staggering total of $194.2 million, encompassing 26 distinct incidents.
The most substantial of these exploits was an address poisoning scam that resulted in a staggering $50 million loss. This single incident accounted for over 65% of December”s total losses, emphasizing the critical need for user vigilance when verifying transaction details. Such attacks typically leverage human error rather than exploiting technical vulnerabilities, making them particularly challenging to prevent solely through code audits.
Alongside this, a private key leak from a multi-signature wallet contributed an additional $27.3 million to the losses, revealing ongoing risks even within enhanced security frameworks. Other incidents included a $7 million breach involving a wallet browser extension and a $3.9 million attack on the Flow protocol. These incidents highlight a diverse range of threats, including scams and key mismanagement, with no single blockchain accounting for the majority of the losses.
Despite the dramatic drop in December, the year-to-date total for crypto-related thefts remains alarmingly high, surpassing $3.3 billion. This figure reflects a broader trend of sophisticated scams, key leaks, and supply chain attacks, with threats exacerbated by state-sponsored actors such as North Korea. Reports suggest that North Korean hackers are increasingly utilizing artificial intelligence and advanced technology to conduct larger and more intricate theft operations.
As the cryptocurrency sector continues to evolve, experts stress the urgent need for improved key management practices and enhanced educational efforts to combat scams. Vulnerabilities in browser wallets are frequently exploited by attackers, making comprehensive security awareness essential for all participants in the cryptocurrency ecosystem.
