      "body": "<html>\n<p>Built on our earlier efforts in analyzing EOS tokens, we have developed an automated system to scan and analyze Ethereum-based (ERC-20) token transfers. Specifically, our system will automatically send out alerts if any suspicious transactions (e.g., involving unreasonably large tokens) occur.</p>\n<p>In particular, on 4/22/2018, 03:28:52 a.m. UTC, our system raised an alarm which is related to an unusual <strong>BEC</strong> token transaction (shown in Figure 1). In this particular transaction, someone transferred an extremely large amount of BEC token —<em>0x8000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000</em>(63 0’s — In fact, there’re actually two such large token transfers, with each transfer involving the same amount of tokens from the same <em>BeautyChain</em> contract but to two different addresses).</p>\n<p><img src=\"https://cdn-images-1.medium.com/max/1600/0*m7WaWrAeQvR4A1Ve.png\" width=\"1059\" height=\"79\"/></p>\n<p><strong>Figure 1: A Suspicious BEC Token Transfer (with huge amount)</strong></p>\n<p>This anomaly prompted us the need to look into the related smart contract code. Our study shows that such transfer comes from an “in-the-wild” attack that exploits a previously unknown vulnerability in the contract. For elaboration, we call this particular vulnerability <strong>batchOverflow</strong>. We point out that batchOverflow is essentially a classic integer overflow issue. In the following, we examine in more details the batchOverflow vulnerability.</p>\n<p><br></p>\n<p><br></p>\n<p><img src=\"https://cdn-images-1.medium.com/max/2000/0*MZnv5M0iCeQ7eCGp.png\" width=\"1098\" height=\"303\"/></p>\n<p><strong>Figure 2: The Vulnerable Function: batchTransfer()</strong></p>\n<p>The vulnerable function is located in <strong>batchTransfer</strong> and the code is shown in Figure 2. As indicated in line 257, the <em>amount</em> local variable is calculated as the product of <em>cnt</em> and <em>_value</em>. The second parameter, i.e., <em>_value</em>, can be an arbitrary 256 bits integer, say <em>0x8000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000,0000</em>(63 0’s). By having two <em>_receivers</em> passed into <em>batchTransfer()</em>, with that extremely large <em>_value</em>, we can overflow <em>amount</em>and make it zero. With <em>amount</em> zeroed, an attacker can then pass the sanity checks in lines 258–259 and make the subtraction in line 261 irrelevant. Finally, here comes the interesting part: as shown in lines 262–265, the balance of the two receivers would be added by the extremely large <strong>_value</strong>without costing a dime in the the attacker’s pocket!</p>\n<p>With that, we further run our system to scan and analyze other contracts. Our results show that <strong>more than a dozen of ERC20 contracts are also vulnerable to batchOverflow</strong>. To demonstrate, we have successfully transacted with one vulnerable contract (that is not tradable in any exchange) as our proof-of-concept exploit (Figure 3).</p>\n<p><img src=\"https://cdn-images-1.medium.com/max/1600/0*iOV7aC5KvTOvIX_7.png\" width=\"1600\" height=\"375\"/></p>\n<p><strong>Figure 3: Proof-of-Concept Exploit against batchOverflow</strong></p>\n<p>By the time of writing this blog, we have also made efforts to contact the teams who own these vulnerable contracts. However, with the touted “code-is-law” principle in Ethereum blockchain, there is no traditional well-known security response mechanism in place to remedy these vulnerable contracts! Moreover, with potential values associated with these tokens, we, as a third-party independent security team, unfortunately are not in the position to react by suspending the trading of vulnerable tokens in various exchanges. Fortunately, effectively at 4:12 p.m. GMT+8, OKEx made an announcement to suspend the withdrawal and trading of BeautyChain (<strong>BEC</strong>), a batchOverflow-affected token. However, other exchanges also need to be coordinated and there still exist other tradable tokens vulnerable to batchOverflow!

-现在已经存在很不同种类的<a href=\"http://coinbin.org/coins\">货币</a>。很多人都喜欢像交易股票和宝可梦卡片那样人们喜欢在这个平台上进行<a href=\"https://www.cryptopia.co.nz/Register?referrer=kennethreitz\">货币交易</a>。 也有人喜欢去用自己的个人电脑或着专业的矿机来<a href=\"https://www.nicehash.com/?refby=386829\">挖矿</a>。加密货币存放在钱包里，可以是在线钱包、本地钱包甚至是记录在一张纸上。 独自挖矿是很困难的，这个过程跟赌博有点像，所以大家通常倾向于加入一个矿池。 (矿池通常运行 <code>stratum</code> 协议) —- 即使你没有挖到任何货币，也会收到奖励，因为你为那些挖到矿的人贡献了自己微博的算力。之后这些挖到的块会按照协议的规则分成许多份。除非你有非常多的算力可以用而且愿意为此花钱，你还可以<a href=\"https://www.nicehash.com/?refby=386829\">租借算力</a>，然后或者是用这些算力来玩一个\"区块链彩票\"的游戏, 尝试自己去挖矿, 或者就和家庭作坊式矿工一样将这些算力提供给矿池来换取奖励。希望已经把事情都讲明白了。</p>\n<h2>☤ 货币市场高效工具</h2>\n<ul>\n  <li><a href=\"http://coinbin.org/\"><strong>Coinbin.org</strong></a> — 用于快速获取货币数据（汇率，预测，，，）用户友好的API\n    <ul>\n      <li><a
