According to statistics from Eagle-Eye , the Chengdu LianAn situational awareness platform , in the past month, various attacks and coin losses occurred frequently, with a total of 15 typical security incidents .
These include:
1. A dapp was attacked on the EOS chain, and the main problem is still the random number issue ;
2. A total of 5 security incidents occurred on the TRON chain . Most of them were problems with game contracts, which led to attackers to achieve steady profits by rolling back transactions, or to maliciously profit by exploiting loopholes in game rules.
3. There is a signature verification vulnerability in the 0X protocol of the decentralized exchange , which allows the signature data to be forged to place malicious orders. Many exchanges and wallets based on the 0x protocol, including Radar Relay, Tokenlon, Star Bit, etc., have urgently suspended trading services.
4. The SOXEX exchange ran away and made hundreds of millions of dollars, involving multiple mainstream currencies such as BTC , ETH , HT , OKB, etc. Some of the funds stolen from TokenStore have been transferred to the exchange for money laundering.
5. More than 8 million US dollars of BTC stolen from Binance were transferred by hackers to multiple wallets, with the intention of transferring the BTC to the exchange for laundering through complex currency mixing.
6. BitpointJapan exchange, My Dash Wallet wallet, Trezor hardware wallet, etc. have experienced security incidents one after another. Among them, Bitpoint was stolen by hackers worth 32 million US dollars in tokens, and My Dash Wallet wallet also lost tens of millions of user assets due to malicious scripts. stolen.
Within the scope that can be counted, losses from security incidents in July exceeded RMB 400 million. Judging from the situation in recent months, security incidents exposed by exchanges and wallets have been on the rise. Chengdu Lian'an would like to remind major exchanges, wallets and other projects to pay attention to security risks, do a good job in reviewing project security, and when necessary, use the power of third-party security companies to ensure system security and fund security. Recently, fund embezzlement, exchange embezzlement and other project side embezzlement incidents have occurred from time to time. Because embezzlement incidents involve huge amounts of money and many victims, it is difficult to recover funds. We hope that investors will keep their eyes open and invest prudently.
