What Are the Top 5 Security Risks for Crypto Projects in 2025?
Smart contract vulnerabilities remain a critical risk
The OWASP Smart Contract Top 10 for 2025 reveals that vulnerabilities in blockchain technology continue to pose significant financial threats. Access control flaws maintain their position as the number one security risk, enabling unauthorized administrative actions and function exploits. According to recent data, over $1.42 billion in financial losses occurred due to smart contract vulnerabilities, as documented in Web3HackHub research and Immunefi's Crypto Losses Report.
| Vulnerability Type | Risk Level | Position in 2025 OWASP Ranking |
|---|---|---|
| Access Control | Critical | #1 |
| Reentrancy Attacks | Critical | #5 |
| Denial of Service | High | #10 |
Particularly concerning is that many 2024-2025 DeFi losses stem not from novel exploits but from well-known vulnerabilities that continue to plague projects. Denial of Service (DoS) attacks remain prominent, where attackers consume excessive gas or exploit expensive contract functions to render smart contracts unusable or severely degraded in performance.
The evolving complexity of Web3 security necessitates proactive risk management strategies. Security experts emphasize that comprehensive protection extends beyond merely checking for OWASP Top 10 vulnerabilities—effective security requires analyzing, simulating, and defending against all potential attack vectors. For blockchain projects seeking robust protection, implementing proper validation techniques, access controls, and systematic auditing processes has become essential in addressing these persistent security challenges.
Cross-chain bridge attacks continue to pose major threats
The security landscape of cross-chain bridges remains perilous in 2025, with hackers successfully exploiting vulnerabilities across multiple networks. The crypto community has witnessed unprecedented losses exceeding $3 billion from 119 bridge-related hacks by mid-2025, surpassing 2024's total by over 50%. Bridge exploitations alone account for $1.5 billion, representing 50.1% of all crypto theft.
A notable incident occurred in June 2025 when Force Bridge on the Nervos Network was compromised, resulting in the theft of over $3 million in digital assets. This attack joins 20 other crypto-related security breaches recorded in May 2025 alone.
| Bridge Security Statistics 2025 | Figures |
|---|---|
| Total crypto losses | $3+ billion |
| Number of hacks | 119 |
| Bridge exploitation percentage | 50.1% |
| Bridge exploitation amount | $1.5+ billion |
Security experts recommend using official canonical bridges for significant transfers, implementing transaction caps, and employing thorough validation protocols. The fundamental vulnerability stems from the trust architecture—whether destination chains can reliably verify source chain events. Various bridges employ different security models, including validator sets, watchers, and proof systems, each with unique failure modes requiring specialized risk management approaches.
Centralized exchange hacks still a significant concern
Centralized exchange security breaches remain a critical threat in 2025, with hackers stealing an unprecedented $2.17 billion in just the first half of the year—already exceeding full-year 2024 totals. February 2025 witnessed the largest single exchange theft in crypto history when attackers drained $1.5 billion from Bybit, demonstrating the escalating sophistication of threat actors in the space.
The scale and frequency of these attacks are alarming, as illustrated by recent major incidents:
| Exchange/Platform | Date | Amount Stolen |
|---|---|---|
| Bybit | Feb 2025 | $1.5 billion |
| European DeFi Exchange | 2025 | $26 million |
| M2 Exchange | Oct 2024 | $13.7 million |
| Various hot wallet breaches | 2025 | $200+ million |
Hot wallet vulnerabilities represent a particular concern, accounting for approximately 62% of total stolen crypto funds from exchange hacks in 2025. Additionally, social engineering scams have resulted in approximately $300 million in user losses annually across major crypto exchanges.
These persistent security challenges highlight the urgent need for exchanges to implement enhanced security measures, including improved access controls, independent security audits, cold storage solutions, and advanced threat detection systems. For SLX investors and users, selecting platforms with proven security track records and robust protection mechanisms remains paramount in this high-risk environment.
