New Hacking Patterns: Off-Chain Systems in Focus
The Chairman of the blockchain security company Halborn, Rob Behnke, said that the latest trend of cyber criminals in their hacking system is to focus more on off-chain systems for high-value hacks. This system can be recognized and notified through smart contract security audits, which are easier for scammers to attack than identifying important vulnerabilities in smart contracts.
Today, cyber criminals are becoming more civilized and begin to focus more on back-end systems and infrastructure. Hence, the platforms need to have efficient security measures as well as procedures in place to prevent these hazards.
