| 20080263156 | Secure Transactional Communication - Systems for providing sign-up email addresses are disclosed herein. A user may set up a sign-up email address for receiving emails from a trusted, Internet-based enterprise. The user may set up a dedicated mailbox folder associated with the sign-up email address or enterprise. The email server may automatically direct emails coming from that enterprise into that folder. To “unsubscribe,” the user needs only to delete the folder or the sign-up address. Emails from the enterprise to the sign-up address may be highlighted in the user's main inbox. Thus, the user may be assured that any such email is truly from the enterprise, and not a phishing expedition or spam. Such systems also provide the user with effective tools to recognize phish or spam emails that appear to be from the trusted enterprise and not to act on them. | 10-23-2008 |
| 20080313285 | POST TRANSIT SPAM FILTERING - A system filters for electronic messages received from recently identified sources of unsolicited spam. A database comprises information regarding electronic messages that were previously received. The information may comprise an identification of the source of the electronic message. A server is programmed to identify sources of unsolicited electronic messages and search the database for electronic messages previously received from the identified source. The server is programmed to attempt to remove the previously received electronic messages originating from the identified source of spam from users' electronic message boxes prior to being viewed by the intended recipients. | 12-18-2008 |
| 20080320095 | Determination Of Participation In A Malicious Software Campaign - Sources of spam, such as botnets, are detected by analyzing message traffic for behavioral patterns and indications of suspicious content. The content of a known malicious source is analyzed. Message traffic associated with the known malicious source is analyzed. Associated message traffic includes messages sent directly from the known malicious source to recipients, and messages sent from the recipients to subsequent direct and indirect recipients. Portions of the content of the known malicious source are selected and content of associated message traffic is analyzed for an indication of the selected content. If the selected content is found in the content of a message, the source of the message is determined to be a source of spam. Associated message traffic is additionally analyzed for behavioral patterns, such as anomalies and/or flurries of activity, to determine a potential malicious source. | 12-25-2008 |
| 20110067109 | SYSTEM AND METHOD OF CACHING DECISIONS ON WHEN TO SCAN FOR MALWARE - In accordance with this invention, a system, method, and computer-readable medium that selectively scans files stored on a computing device for malware is provided. One aspect of the present invention includes identifying files that need to be scanned for malware when a software update that includes a malware signature is received. More specifically, attributes of the new malware are identified by searching metadata associated with the malware. Then, the method searches a scan cache and determines whether each file with an entry in the scan cache is the type that may be infected by the malware. If a file is the type that may be infected by the malware, the file is scanned for malware when a scanning event such as an I/O request occurs. Conversely, if the file is not the type that may be infected by the malware, the file may be accessed without a scan being performed. | 03-17-2011 |
