Overview According to the statistics of the hacking archive of slow fog blockchain, the total loss since the security incidents occurred in September is about 100 million US dollars. According to the analysis of the slow fog security team, the attacker's means are the same as those of the attack. They all borrowed more than expected funds by manipulating interest rates to achieve the attack. According to the analysis, the stolen funds have been transferred to a pledge contract of the cross-chain financing platform, and the loss is about 10,000 US dollars. The attack is because the function is not verified, so that the attacker can manipulate the attacker to repeatedly call and collect the reward, and then call to convert the reward into the pledged amount. Finally, the attacker decentralized the over-mortgaged stable currency agreement by withdrawing the reward. The key to this vulnerability lies in the low liquidity of the pool. The attacker used this vulnerability to manipulate the market. The attacker returned 10,000 pieces to the agreement. The robot was attacked and lost about 1,000 pieces. The slow fog security team analyzed the core reason of the attack. It is the function used to trigger arbitrage in the contract that lacks authentication. The attacker calls this function to convert the tokens in the contract into the pool and then use the funds of the lightning loan to make reverse conversion and gain profits. The Australian cryptocurrency exchange suspected that the private key was leaked and the hot wallet was stolen, resulting in a loss of more than about 10,000 US dollars. The stable currency agreement on the Ethereum was attacked by lightning loan, resulting in a loss of about 10,000 US dollars. The root cause of this attack was when casting share tokens. The attacker used this problem to get extra share tokens, but the attacker stole it and then burned it. The attacker extracted the contract from it before the attack, which means that the attacker lost it in the whole process. He posted a tweet saying that a targeted security hole occurred recently because the owner administrator account was invaded. The attacker used the invaded administrator wallet to transfer the ownership role to their wallet so that they could cast a large number. And took an attacker from the liquidity pool on the Internet, and transferred a total of 10 and the rest of the administrator's wallet to his own wallet. The insurance fund lost about $10,000 due to liquidation. The company tweeted that some of its keys were accessed without authorization. The attack caused a loss of about $10,000. According to the analysis and statistics of the slow fog security team, the hacker attack caused a loss of about $100 million. The original hot wallet and cross-chain bridge were attacked and lost up to hundreds of millions of dollars. A tweet was released on April, and it was said that the attacked loss was about ten thousand dollars. According to the analysis of the slow fog security team, the root cause of this attack was to calculate the number of tokens needed in the exchange of the current price to the border scale price, which would increase the liquidity and the compound interest of the handling fee because of the reinvestment curve, resulting in a larger calculation result than expected, which could cover the user's exchange needs, but the actual price has crossed the border scale, making the agreement think that the current price is higher than expected. The liquidity within the scale has met the needs of exchange, so the liquidity update was not carried out, which eventually led to the reverse exchange. When crossing the border scale, the liquidity increased twice, which made the attacker get more tokens than expected. The details show that the huge amount of double liquidity was hacked. According to incomplete statistics, this month's events accounted for the highest proportion, followed by the ecological details. The following figure summarizes that the losses this month totaled US$ 100 million, accounting for about the total loss of security incidents this month, accounting for the security of this month. Users with the number of incidents should fully understand the background of the project before participating in the project. The team carefully chooses the investment project. Liquidity utilization incidents have caused losses to the project party of about 10,000 US dollars. The project party should strengthen the monitoring of the liquidity pool to effectively prevent and timely respond to potential security threats. The security incidents are caused by loopholes in services provided by third parties. Before introducing third-party services, the project party should consider its security for detailed review and verification, or entrust a security audit company to conduct security audits on services provided by third parties. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
