Security and data highlights:

Security alert: third-party token issuance platforms or hidden backdoor code issue and steal substitute coins

Beijing Lianan Security Center recently received a report from the project party that after its ERC20 contract was deployed to generate tokens, it was found that there were unknown token transfers on the chain. After investigation, the project party used a third-party ERC20 contract release platform in the process of setting and publishing the contract. This platform automatically generated a contract code based on the project's token supply and other settings, and added a piece of code to privately oversupply. Tokens totaling 1% and transferred to the designated address.

According to Zer0Man, a security expert at Beijing Chain Security, we conducted relevant tests on the platform. During the entire process, the platform did not give any hints about the related multiple tokens and private transfers, which is consistent with the project party's experience. In essence, this is a kind of hidden malicious backdoor without its customer's permission, which aims to multiply and steal substitute coins, and the transaction will be realized when it is listed on the exchange. From its now hidden address, it has obtained the limit of seven tokens, and has transferred the project tokens listed on it to relevant exchanges.

Part of the "Weibo Data Leakage" information from the sale of ETH collected into the exchange

According to the monitoring system, 57.31 ETH suspected to be related to the “Weibo Data Leak” event were collected and flowed to the HitBTC exchange.

According to data analyst SXWK, after the relevant data breach, we monitored the transaction address provided by the newsletter. Although the data sellers gave different addresses to different buyers, they recently collected a total of 57.31 ETH from 155 addresses, including our monitoring address, into the new address, and then transferred to the exchange. Most of these addresses were traded after the data breach, and most of them were traded only once, and most of the amounts involved were between 0.3 and 0.5 ETH.
