A Year of Trust Crises: Web3's Most Shocking Cases of 2025

The Web3 ecosystem in 2025 has been marked by an alarming series of incidents that challenge fundamental assumptions about security and governance. Drawing insights from analysis by Eric and coverage from Foresight News, the industry witnessed multiple outlandish breaches that collectively exposed vulnerabilities across protocols, exchanges, and market mechanisms.

The year opened with a coordinated manipulation campaign centered on a meme coin, where a sophisticated team orchestrated a scheme to extract over $100 million through coordinated trading and artificial price manipulation. This case underscored how decentralized markets remain susceptible to well-coordinated actors operating in plain sight.

Internal Betrayals and Embezzlement

Institutional trust proved equally fragile. An Infini employee’s embezzlement scheme, which siphoned approximately $50 million, revealed gaps in internal controls and fund segregation practices. The incident highlighted how even established entities can become targets of insider threats when oversight mechanisms prove inadequate.

Oracle Vulnerabilities and Market Manipulation

The UMA ecosystem experienced significant turmoil when a whale strategically exploited Polymarket’s oracle architecture to manipulate price feeds. This outlandish manipulation demonstrated that even purportedly decentralized oracle solutions remain vulnerable to sophisticated attacks from well-capitalized participants.

Governance and Regulatory Pressure Points

Additional controversies emerged across multiple protocols. The TUSD reserve fund dispute raised questions about stablecoin backing and transparency. Zerebro faced a dramatic crisis when a co-founder’s fabricated death hoax destabilized community confidence. Conflux’s failed reverse shell listing attempt signaled broader challenges in Web3’s path toward institutional adoption.

Systemic Lessons for the Ecosystem

These 2025 incidents collectively expose three critical gaps: insufficient surveillance mechanisms for suspicious trading patterns, inadequate internal governance frameworks, and oracle designs vulnerable to high-impact manipulation. As Web3 continues maturing, addressing these structural vulnerabilities remains essential for sustainable growth and institutional trust.
