Hacken Report Flags $3.1B Web3 Meltdown, 1,025% Spike in AI Assaults

Key Takeaways:

• Web3 platforms misplaced $3.1 billion in H1 2025, already surpassing full-year 2024 losses.
• Entry management failures had been the main trigger, adopted by phishing and good contract bugs.
• AI-related assault vectors rose by 1,025%, exhibiting dangers in inference layers and APIs.

Web3 initiatives misplaced $3.1 billion to exploits and scams within the first half of 2025, in response to the Hacken 2025 Half-12 months Web3 Safety Report printed July 24.

The report states that the quantity misplaced in H1 this 12 months has already exceeded the entire losses recorded throughout all of 2024. It attributes $1.83 billion of this quantity to entry management exploits, nearly all of which occurred in Q1.

AI-Associated Exploits Explode by 10x in Web3

Phishing and social engineering assaults accounted for $600 million, a pointy improve from the earlier 12 months. One other $263 million was misplaced resulting from good contract vulnerabilities, marking DeFi’s most damaging quarter since early 2023.

Hacken recognized a surge in AI-related exploits, with incident quantity rising by 1,025% in comparison with H2 2024. These circumstances stemmed from points corresponding to insecure API design, improper mannequin entry restrictions, and weak person enter filtering in AI inference layers.

The one largest incident within the interval was the $290 million Munchables breach, adopted by $136 million misplaced within the Pike Finance sequence of assaults. The Uniswap V4 ecosystem additionally recorded its first main hook-related exploit, leading to a $12 million loss.

In accordance with the report, Ethereum accounted for 61.4% of whole losses, whereas BNB Chain and Arbitrum represented 20.2% and 11.4%, respectively. Exploits on Ethereum L2s and alt-L1s made up the rest.

Safety Enhancements in Exigent Want

“2025 has been a wake-up name,” mentioned Hacken Co-Founder and CBDO Yevheniia Broshevan. “As blockchain reaches enterprise scale and rules advance, cybersecurity turns into a core enterprise operate.”

The report recommends steady monitoring and automatic protection techniques to deal with rising threats. It additionally warns that customary auditing stays inadequate given the elevated complexity of built-in techniques and AI fashions in Web3 environments.

DeFi protocols made up practically 69% of all incidents tracked in H1 2025. CeFi incidents had been fewer however tended to end in larger particular person losses. The report additionally famous a rising overlap between monetary and infrastructure assault vectors.

The rise in AI-driven exploits exposes the problem dealing with the crypto business: the speedy adoption of complicated applied sciences outpacing the event of safety frameworks.

On the similar time, geopolitical actors and financially motivated teams have begun to deal with blockchain infrastructure as high-value targets. The convergence of conventional cybersecurity threats with on-chain vulnerabilities could require new regulatory coordination between Web3-native companies, nationwide companies, and cybersecurity distributors.

Ceaselessly Requested Questions (FAQs)

How may rules like MiCA or the EU AI Act affect future Web3 safety practices?

These frameworks could impose formal governance, mannequin validation necessities, and real-time monitoring requirements that drive protocols to combine cybersecurity by design fairly than after deployment.

Are smaller protocols extra susceptible to those complicated assaults?

Sure. The report implies that restricted technical sources and overreliance on third-party tooling depart smaller groups uncovered, particularly as AI integrations broaden with out clear defensive requirements.

Is there any indication of coordination between risk actors?

Whereas not explicitly detailed, the rise in refined, cross-layer assaults suggests potential collaboration or tooling exchanges between financially motivated hackers and extra organized adversarial teams.
