KEY TAKEAWAYS
- The cryptocurrency sector suffered over $2 billion in losses in Q1 2025, with Bybit’s $1.46 billion exploit being the largest incident.
- Access control exploits were the primary cause of losses, with Safe multisig wallets being significantly affected.
- North Korean hackers were implicated in the Bybit hack, highlighting the role of state-sponsored cyber operations.
- Centralized finance platforms like Bybit and Phemex were more vulnerable compared to decentralized finance platforms.
In the first quarter of 2025, the cryptocurrency sector witnessed a staggering loss of over $2 billion due to various security breaches, with Bybit’s $1.46 billion exploit marking the largest incident. According to a report by crypto cybersecurity firm Hacken, access control exploits, rug pulls, phishing scams, and smart contract vulnerabilities were the primary culprits behind these losses.
Access control exploits emerged as the most significant threat, accounting for over $1.6 billion in losses. These vulnerabilities have become the most pressing security issue in the industry, with the largest hacks involving Safe multisig wallets. The Bybit hack on February 21, which resulted in $1.46 billion being stolen, stands as the largest in crypto history. Despite the massive breach, Bybit managed to cover all user losses.
North Korean Involvement and CeFi Vulnerabilities
Reports suggest that North Korean hackers were behind the Bybit hack, controlling over 11,000 cryptocurrency wallets used to launder the stolen funds. This highlights the increasing sophistication and scale of state-sponsored cyber operations in the crypto space.
Centralized finance (CeFi) platforms, including Bybit and Phemex, have been particularly vulnerable, suffering over $1.5 billion in losses due to compromised signer workflows and access control failures. In contrast, decentralized finance (DeFi) platforms have managed to contain their losses more effectively.
Social Manipulation and Emerging Laundering Techniques
Beyond technical vulnerabilities, social manipulation remains a significant attack vector. The LIBRA token rug pull, which drained nearly $300 million, shocked the community with its blend of political hype and insider trading. Phishing scams also resulted in nearly $100 million in losses, exploiting poor user security practices.
While smart contract bugs accounted for less than 2% of total losses, they still caused $29 million in damage. Projects like zkLend experienced breaches, underscoring ongoing issues with code quality and maintenance.
Attackers are not only stealing more but are also improving their methods for hiding stolen funds. New laundering techniques, such as using perpetual exchanges and fake sandwich attacks, are being employed to evade detection.

Why This Matters: Impact, Industry Trends & Expert Insights
The first quarter of 2025 saw a dramatic increase in cryptocurrency losses due to hacks, totaling over $2 billion, with the Bybit exchange suffering the most significant breach. This event underscores the vulnerabilities present in centralized finance platforms.
A recent Cryptonomist report highlights significant vulnerabilities and escalating threats in cryptocurrency security breaches. The Bybit hack exemplifies these trends, particularly with access control exploits being a major factor. This aligns with the news event’s emphasis on the growing threat of cyberattacks targeting centralized platforms.
As per insights from a Cointelegraph report, experts emphasize the need for enhanced security measures, not only on-chain but also across front-end interfaces and internal processes. This supports the news event’s focus on the critical need for improved security protocols to protect digital assets.
