Introduction to the Global Cryptocurrency Security Landscape in 2025
The global cryptocurrency industry faced one of its most challenging years in terms of security in 2025, marked by large-scale heists and a high concentration of losses in few incidents. According to Chainalysis, a firm specializing in blockchain and cryptocurrency ecosystem analysis, the total funds stolen by January to early December exceeded $3.4 billion.
Major Attacks Dominate Annual Losses
The three largest cyberattacks in 2025 accounted for 69% of all service losses, creating a scenario where few significant events largely define the annual behavior of cryptocurrency-related crime. One such event was the March attack on Bybit, which accounted for nearly half of all annual losses at $1.5 billion.
North Korea’s Persistent Threat
Beyond the total amount stolen, the data analysis reveals a significant shift in attack patterns. One key aspect is North Korea’s continued prominence as the primary threat zone. In 2025, thefts originating from North Korea reached approximately $2 billion, making it the most severe year in terms of stolen value. This elevated the historical total associated with North Korean-origin thefts to around $6.75 billion.
Rise in Personal Wallet Attacks
Another structural change observed is the sustained increase in attacks targeting personal wallets or accounts. Wallets are digital tools that allow users to store, send, and receive cryptocurrencies through applications, physical devices, or digital extensions.
- In 2022, such incidents represented only 7.3% of the total stolen value, a relatively minor portion within the overall attacks.
- By 2024, this proportion had grown significantly to 44%, reflecting increased individual user exposure within the crypto ecosystem.
- In 2025, personal wallet attacks accounted for about 37% of total losses, excluding the extraordinary Bybit attack impact. This confirms that while large-scale service attacks remain crucial, individual user compromises continue to be a structural component of the phenomenon and maintain a substantial presence in overall losses.
