This article mainly focuses on the security attacks of the top ten attacks in 2008. The database of cloud service providers was attacked on October, which resulted in the loss of some assets of the main network, involving about $100 million, which was the biggest attack in 2008. Later, the official said that he had contacted Google and the slow fog security team to assist in the investigation. The official said that the rest of the losses would be paid in the form of bond tokens and repurchased with profits. The loan agreement was attacked, and the attacker made about $100 million. According to the slow fog, The security team analyzed the attacker's whole attack process, which mainly used the funds of lightning loan to deposit, and then directly donated the funds to the reserve address after two superimposed leveraged loans to trigger the liquidation logic. Finally, all the remaining funds were arbitrage through soft liquidation. There are two main reasons for the attack. The first point is that after donating the funds to the reserve address, it is not checked whether it is in a burst state, which can directly trigger the soft liquidation mechanism. The second point is that the high leverage triggers the soft liquidation. The value of the calculation logic will increase, which will cause the liquidator to obtain most of the mortgaged funds of the liquidator only by transferring part of the liabilities to himself. Because the value of the mortgaged funds is greater than the value of the liabilities, the liquidator can successfully withdraw the obtained funds through his own health coefficient check. On March, he tweeted that the attacker had returned all the funds stolen from the agreement after successful negotiation. On March, he published a blog called War and Peace. It describes the background, handling process and other details of this attack. According to the analysis of the slow fog security team, the loss caused by the hacker attack on the exchange on March is about 100 million US dollars. From the quick and professional approach of the attacker, it is speculated that it is a typical attacker or a hacker organization for North Korea. Sun Yuchen said that the team has successfully identified and frozen some assets related to the hacker address. The current loss of operating income within the controllable range can make up for these losses, and the affected funds will be fully repaid on March. The hosted lending platform and encrypted infrastructure platform were hacked and lost about $100 million because of the smart contract loopholes, among which the hacker removed about $100 million in original packaging tokens and $100 million in tokens from a vault. According to the analysis of the slow fog security team, the root cause of the attack was that the cost of collateral needed by the attacker to quote by the Oracle was much lower than that of the attack, thus manipulating the market and liquidating other users by maliciously submitting the wrong price. In addition, it was said that the incident had nothing to do with the vault. Whether the smart contract is broken or not, both teams are committed to eliminating liquidity to reduce the hacker's behavior of converting stolen tokens into other assets.
