Beosin: The total loss of various security incidents in November exceeded 518 million US dollars

According to the monitoring of Beosin EagleEye, a subsidiary of Beosin, in November 2022, the number of various security incidents and the amount involved will decrease compared with October. In November, more than 18 more typical security incidents occurred, and the total loss of various security incidents exceeded 518 million US dollars. Attacks in the DeFi field this month have decreased compared with last month. The biggest security incident in November was shortly after the FTX exchange filed for bankruptcy, a hacker stole about $440 million in funds and continued to transfer to the BTC chain. Fraudulent escape incidents are still high this month, and some project parties have paid more than tens of millions of dollars. Wallet security incidents and private key leaks have increased this month. The Beosin security team recommends that project owners and users should pay attention to the security of wallets, protect private keys, standardize operations, and do not click on links of unknown origin. 80% of the attacks this month originated from the exploitation of contract vulnerabilities. It is recommended to seek a professional company to conduct a security audit before the project goes live.
