Cryptocurrency theft reached an unprecedented peak during the first half of 2025, according to Chainalysis' analysis.
In the ever-evolving world of cryptocurrencies, 2025 has seen a surge in cybercrime activities. According to the latest report by Chainalysis, a leading blockchain analysis firm, the most commonly stolen cryptocurrencies are predominantly Bitcoin (BTC) and assets lost via access-control exploits, accounting for about 59% of total crypto thefts.
The attacks have evolved from exploiting code flaws to targeting human processes such as key leakage and phishing, indicating that user-level security remains a critical vulnerability despite growing technical safeguards. Hackers have been targeting high-net-worth individuals who hold large amounts of bitcoin.
The largest single theft in 2025 was the $1.5 billion hack of the centralized exchange Bybit's Ethereum cold wallet, accounting for 69% of all funds stolen from crypto services this year. This incident has significantly driven the total theft value in 2025.
Regions with the most activity in crypto crime are the United States, Germany, Russia, Canada, Japan, Indonesia, and South Korea. Rapid growth in victim totals year-over-year is observed in Eastern Europe, the Middle East and North Africa (MENA), and Central and Southern Asia and Oceania (CSAO).
Interestingly, North America dominates the charts in terms of stolen bitcoin and altcoins, with the United States seeing the highest victim count in crypto crime. However, Sub-Saharan Africa remains the region with the lowest criminal crypto activity.
The report found that illicit actors have stolen more cryptocurrencies from crypto exchanges and services by the end of June 2025 than in any other year. At this pace, more than $4.3 billion could be lost by companies offering crypto services to the hands of criminal elements by the end of 2025.
Another concerning trend is the increase in physical, violent attacks as a tactic to gain access to individual crypto holdings. These violent attacks are set to occur twice as much as they did in 2024 by the end of the year.
Non-bitcoin wallets such as Solana have also seen a surge in individual wallet hacks. Chainalysis classifies transactions involving funds sent to addresses suspected of unlawful activities as illicit. The cumulative value of funds stolen from crypto services has climbed above $2 billion within the first half of 2025, faster than in any period in the last four years.
As the crypto market continues to grow, it's crucial for users to prioritise their security measures. Exchanges are improving their security, but the trend of personal wallet hacks is increasing due to increased individual crypto adoption. Users are advised to be vigilant against phishing attacks and to secure their private keys effectively.
In conclusion, Bitcoin remains the primary crypto target, access-control weaknesses dominate the attack vectors, and crypto crime is most rampant in technologically advanced and emerging market regions experiencing rapid growth in crypto adoption. The 2025 Mid-Year Crypto Crime Report by Chainalysis provides a comprehensive overview of the current state of crypto crime and serves as a call to action for the crypto community to strengthen their security measures.
