In the statistic range, the loss of security incidents in August exceeded RMB 60 million. Although compared with last month's situation, the number of security incidents decreased slightly this month, and the losses were relatively reduced. However, the occurrence of exchange security incidents is still on the rise, and the main attack method of hackers is exploitation. The security awareness of exchanges still needs to be strengthened. .
In addition, new security issues have arisen, and problems such as brick arbitrage, fraud, and server failures have increased.
In view of the current new situation of blockchain security, Chengdu Chain Security reminds the project parties to pay attention to security risks, especially exchanges. Often exchange security incidents involve huge amounts of money, and it is even more necessary to enhance security awareness and conduct project security review.
It is suggested that the blockchain project should strengthen its technical capabilities, and it will have a sense of enhancing system architecture security during system design and development, and establish a sound security architecture system and emergency response mechanism. If necessary, you can find a security company to cooperate, through third-party technical support, security testing, security hardening, reduce loopholes to avoid unnecessary losses.
