Blockchain Data Interception

Threat

Blockchain data interception involves unauthorized surveillance or acquisition of information transiting to or from distributed ledgers. This often targets network traffic, aiming to glean insights into transaction broadcasts, wallet addresses, or smart contract function calls before final on-chain confirmation. Such activity can precede transaction manipulation or front-running, especially in high-frequency trading environments for crypto derivatives. Adversaries might employ packet sniffing or compromised network nodes to capture this data stream.
