According to the statistics of Eagle-Eye, a situational awareness platform of Chengdu Chain Security, various attacks and coin loss incidents occurred frequently in August, and a total of 11 typical security incidents occurred.
These include: 1. There were 3 dapp attacks on the EOS chain, and the hackers made more than 20,000 EOS in profits. 2. A malicious website forged the Electrum website for phishing, and a user claimed to have stolen 700 bitcoins. 3. Telegram's "brick-moving arbitrage" scams are emerging one after another, and a new victim was defrauded of 201 ETH. 4. There is a problem with the Amazon server AWS, and the data of multiple exchanges is abnormal and users are restricted from withdrawing coins. 5. Several exchanges such as Binance, Bitstamp, CoinTiger, and Citex broke out security incidents one after another. Among them, the Binance and Bitstamp exchanges are mainly concerned with the leakage of user information. The number of leaked information users is relatively large, involving multiple countries; VEIL tokens were attacked by Zerocoin, causing VEIL transactions to be suspended.
Within the scope of statistics, the loss of security incidents in August exceeded 60 million yuan. Although compared with last month, the number of security incidents this month has decreased slightly, and the losses have also been relatively reduced, but the occurrence of security incidents on exchanges is still on the rise, and the main attack method of hackers is exploiting loopholes, and the security awareness of exchanges still needs to be strengthened . In addition, new security issues have emerged, and problems such as brick-and-mortar arbitrage, fraud, and server failures have increased.
In view of the current new situation of blockchain security, Chengdu Lianan hereby reminds the project party to pay attention to security risks, especially exchanges, which often involve huge amounts of money in security incidents, and it is even more necessary to enhance security awareness and do a good job in project security review. It is recommended that blockchain projects strengthen their technical capabilities, consciously enhance the security of the system architecture during system design and development, and establish a complete security architecture system and emergency response mechanism. If necessary, you can cooperate with a security company to reduce vulnerabilities through third-party technical support, security testing, and security reinforcement to avoid unnecessary losses. When the project is running, the security situation awareness system can be used to monitor in real time and give an early warning and alarm. If there is any asset loss, you can find a security company to track the source of assets on the chain.
