A security protocol is a set of rules and procedures designed to protect data and communications within a computer network or system. These protocols specify how data should be encrypted, authenticated, and transmitted securely to prevent unauthorized access, tampering, or disclosure. They are fundamental for establishing trust and ensuring the integrity of digital interactions. Examples include TLS for web browsing and various cryptographic protocols.
Context
Security protocols are foundational to the operation and trustworthiness of blockchain networks and digital asset transactions. Protocols like Proof of Work or Proof of Stake secure the underlying distributed ledger, while cryptographic protocols protect individual transactions and wallet interactions. News often discusses the effectiveness and evolution of these protocols, especially in the context of new attack vectors or advancements in quantum computing.
A core software library vulnerability allowed an oversized transaction hash to bypass validation, creating a consensus failure and a critical chain split.
The LeakyStealer malware family uses low-level API injection via LeakyInjector to bypass detection and systematically drain browser-based crypto wallets.
