Introduction: A Tough Year for Crypto
The year 2025 will be etched in crypto history as the year trust in the industry was shaken to its core. With total losses surpassing $3.5 billion due to hacks, scams, and insider abuse, the ecosystem revealed vulnerabilities that go beyond technology—highlighting significant governance and human errors.
Supply-Chain Hacks: A Game-Changer
One of the most significant events of 2025 was the $1.5 billion Bybit breach in February, considered the largest decentralized finance (DeFi) hack to date. Unlike traditional exploits targeting smart contracts, this attack targeted the supply chain. Hackers compromised Safe Wallet’s signing interface, exploiting a trusted infrastructure and exposing an industry blind spot. Security firm CertiK later confirmed that supply-chain attacks caused $1.45 billion in losses, making them the year’s deadliest threat. To mitigate the damage, Bybit guaranteed asset backing and launched a massive bounty program—shifting industry attention toward strengthening security protocols.
The Rise of AI-Powered Scams
Artificial intelligence (AI) became a stronghold for cybercriminals in 2025. This technological leap facilitated phishing, voice cloning, and realistic impersonation scams. One high-profile incident involved attackers using AI to target Coinbase support staff, resulting in millions of dollars in damages. Pig butchering scams—fraudulent operations built on emotional manipulation—also escalated. In some cases, victims lost entire crypto investments, like retirement Bitcoin funds. Globally, pig butchering drained billions in wealth, with U.S. authorities recovering over $225 million related to such schemes.
Layer 1 Chains Under Attack
Spring and summer of 2025 were especially brutal for smaller Layer 1 blockchain protocols. Rug pulls, fake audits, and AI-generated whitepapers plagued ecosystems like Solana, tarnishing its reputation. Validator failures and stablecoin depegging across other platforms introduced volatility, leaving retail investors at elevated risks.
A Shift Toward Retail Losses
While 2025 experienced fewer high-profile breaches compared to past years, retail users suffered amplified losses. Weak key management, phishing links, and fake wallet infrastructure drained individual accounts, marking a rising trend of scams targeting everyday investors. One example involved fake wallet updates, which siphoned funds from thousands of unsuspecting users.
Key Lessons for a Safer Crypto Future
The challenges of 2025 underscored the pressing need for robust governance, transparency, and a renewed focus on user protection. Security failures that blend human oversight with technical flaws demonstrated how easily trust can erode in this rapidly evolving industry. The future of crypto depends on how well the industry can adapt, ensure secure infrastructure, and build trust with everyday users.
