Definition ∞ A hot wallet breach is a security incident where a cryptocurrency wallet connected to the internet is compromised, leading to the unauthorized removal of digital assets. Hot wallets are typically used for frequent transactions due to their accessibility, but this online connectivity also makes them more susceptible to cyberattacks. Attackers may exploit software vulnerabilities, phishing schemes, or weak security protocols to gain access to private keys or directly transfer funds. Such breaches often result in significant financial losses for exchanges, platforms, or individual users.
Context ∞ News regularly reports on major hot wallet breaches affecting centralized exchanges or decentralized finance platforms, underscoring the persistent security challenges. The discussion emphasizes the need for robust cybersecurity measures, including multi-factor authentication, regular security audits, and cold storage solutions for the majority of assets. Continuous improvements in wallet security technologies and user education are vital for mitigating this prevalent risk.
