“Willful Negligence” Fuels Web3 Hacks, Claims Immunefi CEO After $27M Multisig Breach

The cryptocurrency sector is grappling with significant security issues once again, as a multisignature wallet linked to a prominent whale was drained of roughly $27.3 million due to a breach of its private key earlier today.

Key Takeaways

A multisig wallet linked to a whale suffered a $27.3 million breach.
The attacker laundered about $12.6 million and still possesses around $2 million in assets.
Breaches in the crypto sector highlight operational risks over technical flaws.
Total crypto losses since 2009 have reached approximately $90 billion.
Immunefi CEO suggests the crypto industry's security issues stem from willful negligence rather than complex technology.

A Major Breach Reveals Ongoing Security Risks

The incident was caused by the compromise of a private key associated with a whale's multisignature wallet, leading to the theft of about $27.3 million.

Despite multisignature wallets being considered an industry-standard for security, this breach underscores the persistent operational vulnerabilities overshadowing the crypto ecosystem. Issues such as private key mismanagement, phishing attacks, and insider threats continue to weaken even the most sophisticated security structures.

Crypto Industry Faces Rising Security Threats

Over the past 15 years, the cryptocurrency industry has experienced losses close to $90 billion from hacks and exploits. According to Immunefi, the rate of theft has drastically increased in recent months.

In November alone, over $276 million was stolen, pushing 2025's total losses to exceed $9.1 billion. Astonishingly, around 10% of all historical crypto losses have occurred within the last year, signaling a rapidly worsening security environment.

Immunefi CEO Highlights ‘Willful Negligence’ in Web3 Security

Mitchell Amador, the founder and CEO of Immunefi—an organization that provides security for over $180 billion in digital assets—asserts that willful negligence, rather than technical challenges, poses the most significant risk to the sector.

“Crypto is facing a pressing security crisis,” Amador remarked. “As ecosystems grow, increased on-chain activities are colliding with diminishing security budgets and an expanding attack surface.”

He emphasizes that 99% of all Web3 projects operate without essential firewalls, and less than 10% utilize modern AI-driven security tools, leaving most protocols vulnerable post-launch.

Post-Launch Vulnerabilities as the Major Cause of Exploits

Amador points out that many high-profile hacks this year were not due to inadequate audits. “Most breaches haven’t occurred because of poor audits,” he noted. “They’ve taken place post-launch, during protocol upgrades, or through integration weaknesses—areas that audits often overlook.”

This trend highlights a shift in how attackers are operating, focusing on vulnerabilities that arise during operational transitions instead of during initial launch phases.

Transitioning to Real-Time Security Strategies

Amador believes the industry needs to move away from static, audit-oriented security models in favor of continuous, automated lifecycle security.

“Current on-chain security frameworks are not mature enough,” he stated. “They still rely on manual assessments and fragmented systems that hinder organizations from adjusting their security measures effectively.”

While there are already technical solutions available, Amador notes that their adoption has been slow, leading to the ongoing exposure of billions in user and institutional funds.

As the crypto sector grows within mainstream finance, the recent $27 million multisig breach should be viewed as more than just a standalone incident. It serves as a crucial warning: if the security culture does not fundamentally shift, losses may continue to escalate faster than the industry's capabilities to defend against them.
