## Briefing

The Web3 ecosystem experienced a critical surge in security incidents during the first half of 2025, resulting in over $2.47 billion in losses across 344 documented events. This substantial capital drain highlights persistent vulnerabilities in digital asset security protocols and user operational security. [Wallet compromises](https://incrypthos.com/security/phishing-attack-compromises-multi-sig-wallet-via-malicious-contract-approval/) emerged as the most financially devastating attack vector, accounting for over $1.7 billion in stolen funds, underscoring the critical need for enhanced custodial safeguards.

## Context

Prior to this period, the digital asset landscape has consistently contended with a diverse array of attack surfaces, ranging from unaudited smart contracts to centralized administrative controls. The prevailing risk environment was characterized by the inherent complexity of interconnected DeFi protocols and the evolving sophistication of threat actors. This environment often enabled attackers to exploit known classes of vulnerabilities, such as logic flaws and [social engineering](https://incrypthos.com/security/thorchain-co-founder-wallet-compromised-via-social-engineering/), to achieve significant financial gains.

## Analysis

The technical mechanics of the incidents primarily involved the compromise of user wallets and the execution of sophisticated phishing campaigns. Wallet compromises, representing the highest financial impact, often stemmed from private key exfiltration or malicious approvals, granting attackers direct control over digital assets. Phishing, while less financially impactful per incident, constituted the most [frequent attack vector](https://incrypthos.com/security/multi-sig-wallet-drained-by-sophisticated-phishing-contract-attack/), leveraging social engineering to trick users into divulging sensitive information or signing malicious transactions. These vectors collectively demonstrate a multi-faceted threat landscape targeting both technical infrastructure and human elements within the Web3 space.
