摘要： A module is configured to identify a phishing Web site. The module identifies email associated with a Web site and transmitted to a plurality of recipients. The module then determines that the Web site has received less than a first threshold amount of traffic before a first time. The module then determines that the Web site has received more than a second threshold amount of traffic between the first time and a second time (i.e., a spike in traffic between the first time and the second time). The module then determines that at least a portion of the more than a second threshold amount of traffic is received as a result of the email associated with the Web site being sent to the plurality of recipients.

摘要： A system and method for filtering unwanted Internet Protocol traffic based on blacklists receives a first blacklist containing a first plurality of Internet protocol addresses associated with unwanted Internet traffic. The system also operates a first plurality of access control lists adapted to block the unwanted Internet traffic from one of the first Internet protocol addresses listed in the first blacklist. The system also assigns a first weight to each of the first Internet protocol addresses based on a reliability of Internet traffic from each of the first Internet protocol addresses. Additionally, the system reduces a first number of the first access control lists to optimally trade off a number of desirable Internet protocol addresses blocked with a number of bad Internet protocol addresses blocked based on the first weight of each of the first Internet protocol addresses.

摘要： Traffic flow from a traffic source with a source IP address to a customer system with a destination IP address is filtered by comparing the source IP address to a customer blacklist. If the source IP address is on the customer blacklist, then traffic to the customer system is blocked; else, traffic to the customer system is allowed. The customer blacklist is generated from a network blacklist, comprising IP addresses of unwanted traffic sources, and a customer whitelist, comprising IP addresses of wanted traffic sources. The customer blacklist is generated by removing from the network blacklist any IP address also on the customer whitelist. The network blacklist is generated by acquiring raw blacklists from reputation systems. IP addresses on the raw blacklists are sorted by prefix groups, which are rank ordered by traffic frequency. Top prefix groups are selected for the network blacklist.
摘要翻译：从具有源IP地址的流量来源到具有目的地IP地址的客户系统的流量通过将源IP地址与客户黑名单进行比较来进行过滤。如果源IP地址在客户黑名单上，则阻止向客户系统的流量; 否则允许客户系统的流量。客户黑名单由网络黑名单生成，包括不想要的流量源的IP地址，以及包含所需流量源的IP地址的客户白名单。客户黑名单是通过从网络黑名单中删除客户白名单中的任何IP地址生成的。网络黑名单是通过从信誉系统获取原始黑名单而生成的。原始黑名单上的IP地址按前缀组排序，按照流量频率进行排序。为网络黑名单选择顶部前缀组。

摘要： A method for providing network access privacy by classifying filter parameters of a group of users who are accessing one or more network destinations. The system includes a means for collecting information from both users, and about network destinations, generating suggestions for a user regarding filter parameters, and filtering network communications of users going to network destinations. In operation, users who are accessing network destinations are prompted to choose from a selection of filter parameters. The information provided by these users is then analyzed and used to generate suggested filter parameters for other users. As users provide more information to the system about various network destinations the system is able to provide more information to users about more network destinations and thus generate more accurate filter parameter suggestions. After a user selects their filter parameters the system filters a range of information coming from the user and going out to the network destination.
摘要翻译：一种通过对正在访问一个或多个网络目的地的一组用户的过滤器参数进行分类来提供网络访问隐私的方法。该系统包括用于从用户和关于网络目的地收集信息的装置，为用户生成关于过滤器参数的建议，以及过滤去往网络目的地的用户的网络通信。在操作中，提示正在访问网络目的地的用户从过滤器参数的选择中进行选择。然后分析这些用户提供的信息，并用于为其他用户生成建议的过滤器参数。随着用户向系统提供关于各种网络目的地的更多信息，系统能够向用户提供关于更多网络目的地的更多信息，从而生成更准确的过滤器参数建议。用户选择过滤器参数后，系统将过滤来自用户的一系列信息，并进入网络目的地。

摘要： According to an aspect of this invention, a method to detect phishing URLs involves: creating a whitelist of URLs using a first regular expression; creating a blacklist of URLs using a second regular expression; comparing a URL to the whitelist; and if the URL is not on the whitelist, comparing the URL to the blacklist. False negatives and positives may be avoided by classifying Internet domain names for the target organization as “legitimate”. This classification leaves a filtered set of URLs with unknown domain names which may be more closely examined to detect a potential phishing URL. Valid domain names may be classified without end-user participation.
摘要翻译：根据本发明的一个方面，一种检测网络钓鱼URL的方法包括：使用第一正则表达式创建URL的白名单; 使用第二个正则表达式创建URL黑名单; 将网址与白名单进行比较; 如果该网址不在白名单中，请将该URL与黑名单进行比较。通过将目标组织的互联网域名分类为“合法”，可以避免虚假的否定和积极性。此类别会留下一组经过筛选的未知域名的URL，可以更仔细地检查以检测潜在的网络钓鱼URL。有效的域名可能没有最终用户的参与分类。
