Key points:

The frequency of crypto hacks remains consistently high, with around 90–100 attacks per year.
Most losses come from major incidents: up to 73% of stolen funds are tied to the 10 largest hacks.
When a project is hacked, losses often reach tens of millions, and most tokens never recover.

Over the past three years, blockchain security has worsened significantly, according to a new Immunefi report.

If a protocol is hacked in 2026, average direct losses are estimated at around $25 million. Token prices drop by up to 61% within six months, and 84% of affected assets never recover. Teams typically spend up to three months dealing with the aftermath, slowing down product development.

The report also highlights a shift in attack patterns. The number of hacks hasn’t decreased, but the average size of each theft has gone down. In 2024–2025, the average loss per incident was $2.2 million, compared to $4.5 million in 2021–2023.

However, overall risk has increased due to large-scale incidents. Most losses now come from a small number of major attacks. The five largest hacks in 2024–2025 accounted for 62% of all stolen funds, while the top ten made up 73%. The Bybit hack alone represented 44% of total losses in 2025.

In total, 425 attacks have been recorded in recent years, resulting in $11.9 billion in losses. The frequency of incidents remains consistently high, at around 90–100 hacks annually.

Crypto market loses $26.5M to hacks in February — lowest level in 11 months

In February 2026, total crypto industry losses from hacks and scams reached $26.5 million — the lowest monthly figure since March 2025.

Centralized exchanges stand out. They accounted for just 10% of attacks but over half of total losses—54.6%. The remaining share comes from DeFi protocols and other projects. As DeFi becomes more interconnected, the potential impact of individual exploits continues to grow.
