I've setup an application for my client, that sends lists of job vacancies to subscribers every Monday morning. The emails use a custom link redirector service, to make the links email friendly, and to count clicks etc. Every week, after the emails are sent, I start receiving error alerts in the logs, for redirector links that can't be decoded. At first I thought this must have been a bug in the coding, and that some end users were unable to click on the links. However I was able to verify that these links were bogus, and had not been created by our system. What seems to be happening, is a bot of some kind must be trying to create random redirector links. What I can't understand is why? The links have clearly been designed to try to mimic the format of the real links. At first glance they look legitimate. They could be identified initially because they included non-hexadecimal characters in the parameters, where the real parameters are always hex encoded. However now the bogus links are also hex encoded. What would be the purpose of this link hacking? Would the attackers be hoping to figure out how the links are encoded, thinking they might be able to then create login links, or password reset links? The other curious thing, is that that these attacks only seem to occur directly after the mail-out. If it was a regular intrusion attempt, I would expect it to just happen at various times throughout the week. Would this be intended to make it look less suspicious, and to make it appear more likely to be legitimate user activity? Note: The. asp is completely arbitrary, it's not actually using classic ASP, I mostly just wanted to use an extension which wouldn't confuse email clients, but would also give hackers less clues about the back-end application environment. Since your links do not contain a target URI, there are only a few possibilities for an attack here:. This would be web reputation hijacking , in which they're using your redirector's reputation in place of the likely bad reputation of their own landing site, thus bypassing URI DNSBLs in spam detection. Another possibility is that they don't like you and they're trying to damage your web reputation. The first two scenarios are likely to harm your web reputation. 问答之家搜索. 首页机器人试图欺骗编码的电子邮件链接，但为什么？ -- hash 领域和 email-spoofing 领域 security 相关的问题 Bots trying to spoof encoded email links, but why? 机器人试图欺骗编码的电子邮件链接，但为什么？ -- hash 领域和 email-spoofing 领域 security 相关的问题 Bots trying to spoof encoded email links, but why? 问题中文. 我已经为我的客户设置了一个申请，它将每周一早晨向订户发送职位空缺列表。电子邮件使用自定义链接重定向器服务，使链接发送电子邮件友好，并计算点击等。此重定向器使用哈希路径参数唯一标识单击。每周，发送电子邮件后，我开始在日志中接收错误警报，因为无法解码的重定向器链接。起初我认为这一定是编码中的错误，并且某些最终用户无法单击链接。但是，我能够验证这些链接是虚假的，尚未由我们的系统创建。似乎发生了什么，是某种机器人必须尝试创建随机重定向器链接。我无法理解的是为什么？链接已清楚地设计用于模拟真实链接的格式。乍一看，他们看起来很合法。它们最初可以识别，因为它们包括参数中的非十六进制字符，其中实际参数始终是十六进制编码。但是现在伪传链接也是十六进制编码的。这个链接黑客的目的是什么？攻击者是否希望弄清楚链接如何编码，认为它们可能能够创建登录链接或密码重置链接？其他好奇的事情，即这些攻击只似乎直接发生在邮件之后。如果是定期入侵尝试，我希望它恰好在整个星期内发生。这将是为了使它看起来不那么可疑，并且使其看起来更有可能是合法的用户活动？如果它有用，那么电子邮件中发送的链接看起来像这样 asp 注意：. This redirector uses a hashed path parameter to uniquely identify the click. In case it's helpful, the links that are sent in the emails look something like this asp Note: The. user Z. 访问无效URL的用户代理是什么？是在您发送电子邮件的国家内IPS的尝试吗？ Daisetsu Z, License: CC BY-SA 4. 具体示例是有效链接的样子以及您看到的无效链接以及链接在邮件中的究竟是有用的。有安全产品扫描邮件并遵循链接以检查此可能是网络钓鱼还是恶意软件，这些可能会以与预期不同的方式从邮件中提取链接。 Steffen Ullrich Z, License: CC BY-SA 4. 您可以在您的电子邮件中发出解码问题，您将电子邮件发送为HTML（我想你这样做），确保使用正确的URL编码。此外，邮件服务器和客户端可以在用户收到它之前获取URL（即要检测恶意软件，垃圾邮件，启用缓存等）。 Securist Z, License: CC BY-SA 4. Securist这是我的第一次想法。散列码可能有一个错误，因此我开始记录发送的每台电子邮件的完整HTML内容。然后，我能够验证我在错误日志中看到的链接，不存在于任何传送的电子邮件中。 user Z, License: CC BY-SA 4. 你提到的是，最初链接尝试不是十六进制编码，那么他们稍后是人为干预。如果是这种情况，也许邮件列表中的某个人是 TTT Z, License: CC BY-SA 4. What are the user agents which are accessing the invalid URLs? Are the attempts from IPs within the country you're sending the emails to? Daisetsu Z, License: CC BY-SA 4. It would be useful to have concrete examples of how a valid link looks like and what invalid links you see and how exactly the link is included in the mail. There are security products which scan mails and follow links to check if this might be phishing or malware and these might extract the link from your mail in a different way than you intended Steffen Ullrich Z, License: CC BY-SA 4. It is possible you have a decoding problem in your e-mail, of you send the email as HTML which I suppose you do , make sure you use the proper URL encoding. Also, mail servers and clients may fetch the URL before the user receives it i. to detect malware, spam, enable caching, etc Securist Z, License: CC BY-SA 4. Securist This was my first thought. That the hashing code may have had a bug, so I started logging the full HTML content of each email sent. I was then able to verify that the links I was seeing in the error logs, didn't exist in any of the delivered emails user Z, License: CC BY-SA 4. Your mention that initially the link attempts were not hex encoded, then later they were, suggests human intervention. If that's the case, perhaps someone in your mailing list is TTT Z, License: CC BY-SA 4. In such a case, the redirection targets in these messages would probably be malicious sites. Adam Katz Z. 基于重定向器的工作方式，实际上无法伪造目标。重定向器只能重定向到已预先添加到新闻稿列表表的URL。人们收到的电子邮件中的链接只有此表中的条目的哈希标识。 user Z, License: CC BY-SA 4. 关于所有这些都可能会这样做，如果他们能够打破散列算法（可能的，因为它只是CRC32），他们可以重定向到我们网站上的旧的过期工作空缺。 user Z, License: CC BY-SA 4. 我应该只添加，即我选择了CRC 32，因为这些链接不需要特别安全，因为这种方式散列的网址比我使用的SHA或其他东西要短得多。 user Z, License: CC BY-SA 4. Based on the way the redirector works, it can't actually fake the target. The redirector can only redirect to URL's that have been pre-added to a NewsletterLink table. The links in the emails that people receive, just have a hashed id for the entries in this table user Z, License: CC BY-SA 4. About all they could possibly do, if they were able to break the hashing algorithm possible, as it's only CRC32 they could redirect to an old expired job-vacancy on our site user Z, License: CC BY-SA 4. I should just add, that I chose CRC 32 because these links don't need to be particularly secure, and because this way the hashed URL's were much shorter than they would have been had I used SHA or something user Z, License: CC BY-SA 4. 更多机器人试图欺骗编码的电子邮件链接，但为什么？的答案请点击这里. two highly trusted algorithms into Javascript 首先，我正在使用我没有编码的bcrypt
