Crypto Hack Trends 2025: $3.3B Lost Despite Fewer Attacks
In 2025, crypto hackers stole $3.3 billion, according to new data from blockchain security company CertiK. Nonetheless, the number of attacks fell precipitously as losses switched to fewer but more advanced supply chain exploits. The decrease in incident numbers indicates that protocol-level security is getting better, even while overall losses remain high. The decline in median stolen sizes suggests that phishing and infrastructure-level attacks are becoming more popular among attackers instead of straightforward coding flaws.
Bybit Hack Highlights Rise of Advanced Supply Chain Attacks
Supply-chain breaches were the most destructive threat, according to CertiK, with only two events resulting in losses of $1.45 billion. Among them was the February $1.4 billion Bybit hack. As more infrastructure providers are targeted by attackers, the report projects an increase in the sophistication of supply chain attacks.

Compared to the previous year, there were 162 fewer security incidents. This suggests that even though hackers are striving for bigger targets, blockchain cybersecurity solutions are getting better. The average loss per hack was $5.3 million, which was 66% more than the year before. But over the same time period, the median loss, which is less affected by outlier instances, dropped 35.75% to $103,966.
Pig Butchering Scam Wipes Out Bitcoin Savings
An investor recently lost all of their Bitcoin retirement funds in a romantic scam driven by artificial intelligence. The “pig butchering” fraud was a long-term emotional manipulation ruse. This strategy was employed by scammers to persuade the investor to send all of their money. A subclass of phishing scams, pig butchering scams cost the industry a total of $5.5 billion in 2024 across 200,000 individual occurrences. The US Department of Justice declared in June that it had seized more than $225 million in cryptocurrency connected to pig butchering schemes.
