我如何使用此信息（或任何其他信息）来识别哪个附加组件导致了此问题？
答案1
我不确定您的具体问题是否属于这种情况，但确实存在已知良好的扩展程序被出售给第三方，然后第三方利用该扩展程序进行恶意攻击的情况。下面是一个讨论此问题的故事：Google Chrome 扩展程序被出售给恶意广告软件公司。
摘抄
Ars Technica 的 Ron Amadeo 最近写道一篇文章关于广告软件供应商购买 Chrome 扩展程序以放置恶意的广告注入更新。
Google Chrome 具有自动更新功能，以确保用户始终使用最新更新。显然，Google Chrome 是由 Google 直接更新的。但是，此更新过程因此包括 Chrome 的扩展程序。Chrome 扩展程序由扩展程序所有者更新，用户可自行判断扩展程序所有者是否值得信赖。
当用户下载扩展程序时，他们就授予扩展程序所有者随时将新代码推送到其浏览器的权限。
不可避免的是，广告软件供应商从扩展程序作者那里购买扩展程序，从而购买用户。这些供应商将广告软件推送给扩展程序的每个用户，这可能会带来危险的浏览体验。
一位 Google 扩展程序作者给出他的个人账户他在一篇博客文章《我卖掉了一个 Chrome 扩展程序，但这是一个糟糕的决定》中谈到了这一点。
我的建议是认真对待这种情况，并禁用不确定的扩展。然后我会监控情况，看看它是会平息还是会继续。
如果这种情况持续发生，那么我会深入研究并开始仔细检查你使用的 DNS 服务器。我通常使用开放DNS正是出于这个原因，因为这项服务（免费）试图通过将 DNS 查找重定向到备用 OpenDNS 页面来阻止攻击媒介。
为什么要关心 DNS？
如果已知主机名与垃圾邮件/黑客/网络钓鱼相关活动有关，OpenDNS DNS 服务器将故意增强您进行查询时返回的结果。它们处于一个独特的位置，因为它们对客户访问的每个站点执行查询，因此它们可以检测到异常（请参见此处）：OPENDNS 网络钓鱼保护， 也这里。
还有什么？
我还会确保您的/etc/hosts文件没有受到损害，并继续使用类似的方法来监控情况nethog，它将显示哪些进程正在访问您的网络。
Amit Agarwal 在不到一小时内就为 Chrome 创建了一个 Feedly 扩展程序，并在不知情的情况下以四位数的价格将其卖给了广告软件供应商。该扩展程序在出售时在 Chrome 上有 30,000 多名用户。新所有者向 Chrome 商店推送了更新，将广告软件和联盟链接注入了用户的浏览体验。虽然由于 Agarwal 的忏悔引起了公众的关注，该扩展程序已被删除，但这种现象在 Chrome 扩展程序中非常常见。
答案2
查看扩展的评论流畅的手势（直接链接）。
如果您按日期对评论进行排序（点击最近的），你会发现几乎所有新评论都是一星评价，并且抱怨恶意广告：
李凯文1天前
出售给添加广告的第三方公司，并提供付费删除广告功能。
苏雷什·纳格斯瓦兰3天前
讨厌广告。它运行良好，直到它开始在我的浏览体验中插入广告。我本来会付费继续使用它，但我强烈反对它的鬼祟行为。它几乎就是间谍软件。
约翰·史密斯6天前
不要使用这个。它会注入 JS 来点击劫持，并导致 https 的 XSS 安全问题。
托马斯·赫拉瓦切克2014 年 2 月 23 日
太垃圾了……还记得未经授权的 URL 偷偷溜走事件吗？然后他们开始强迫用户“捐款”，否则就得忍受广告。它甚至开始在某些页面上滞后（在所有这些“改进”之前情况并非如此）。所以我换成了 CrxMouse，现在一切正常。
凯尔·巴尔2014 年 2 月 19 日
这是一款可靠的鼠标手势扩展程序，但新添加的广告却令人讨厌。首先，因为扩展程序会更新并默默添加广告，所以你不知道它们来自哪里。在这里，我使用多个恶意软件扫描程序扫描我的计算机，因为我收到了随机广告，直到我意识到这是 Smooth Gestures 插入的。
没有任何理由再使用这个扩展，而且我个人想知道是谁开发了这个扩展，这样我就可以确保将来不会安装他们提供的任何东西。
看起来那人就是罪魁祸首。
答案3
除了这里的答案之外，我还发现了一些更有用的资源。
这个 howtogeek文章推荐一个名为Fiddler它充当 Web 调试代理，允许你检查网络请求（目前有一个 alpha 版本Linux 版本）@slm 指出这个答案在 SO 上也有各种类似的程序。
chrome的页面中的开发者模式
chrome://extensions可以检查各个扩展程序在后台运行的进程：
单击打开
background.htmlchrome 的开发人员工具窗口，您可以轻松查看扩展程序包含的各种脚本的源代码。在这种情况下，我注意到supportSexy Undo Close Tab 的源代码树中一个名为 的文件夹，其中包含一个名为 的脚本，background.js该脚本看起来很可疑（它生成随机时间间隔，符合我的症状）。这个其他的 howtogeek文章有一个已知要避免的扩展列表，但更好的是http://www.extensiondefender.com这似乎是用户生成的恶意扩展数据库。但是，他们没有说明某个扩展如何或为何被标记为恶意软件或广告软件，因此也许应该持保留态度。
extensiondefender.com 背后的人（不管他们是谁）还开发了一个非常酷的小扩展，叫做，（鼓声）扩展防御者。这既可以让您扫描现有扩展以查找已知的“坏”扩展，也可以阻止安装黑名单扩展。
因此，在我的 OP 中的扩展中，流畅的手势（感谢@Dennis）和性感撤消关闭标签是广告软件。根据support/background.js后者文件的源代码，我确信其中一个是随机劫持我当前页面的程序，但我需要几天时间才能确定。
另一个有用的扩展是扩展更新通知程序（谢谢@丹尼斯) 它显然会在扩展程序更新时通知您，这有助于在更新添加了此类行为时识别罪魁祸首。
答案4
一个不错的起点是使用 Chrome 扩展程序“shield for chrome”。它将帮助发现存在已知问题的扩展程序。它在 Chrome 网上应用店中提供，免费、精简且非常易于使用。 https://chrome.google.com/webstore/detail/shield-for-chrome/cbaffjopmgmcijlkoafmgnaiciogpdel
或者“扩展防御者”。 https://chrome.google.com/webstore/detail/extension-defender/lkakdehcmmnojcdalpkfgmhphnicaonm?hl=en
