High Value Target

Definition ∞ A High Value Target, in the context of cybersecurity and digital assets, refers to a system, protocol, or individual holding substantial digital assets or critical information, making it an attractive objective for malicious actors. These targets are often associated with large treasuries, prominent decentralized finance protocols, or significant private key holdings. Successful attacks on such targets yield considerable financial gain for attackers. Protecting these targets requires robust security measures and constant vigilance.
Context ∞ News concerning cybersecurity incidents in the crypto space frequently identifies protocols or entities as High Value Targets, especially those with large total value locked (TVL) in decentralized finance. The focus of discussions often centers on the advanced attack vectors employed by hackers, such as flash loan attacks or smart contract exploits, to compromise these systems. The continuous challenge for the industry involves strengthening defenses and implementing proactive security audits to safeguard these attractive objectives from sophisticated threats.
