DYNAMIC ATTACHMENT DELIVERY IN EMAILS FOR ADVANCED MALICIOUS CONTENT FILTERING

摘要

Technologies are described for dynamic attachment delivery in emails for advanced malicious content filtering. An email service may intercept emails with attachments (or other threats such as links, embedded objects, etc.) and detach the threat (e.g., attachment) from the email allowing the email to be forwarded to the recipient without delay. The threat may be sequestered and analyzed. If the threat is determined to be harmless, it may be reattached to the email and the client notified so they can open the attachment, activate the link, or perform comparable actions.

主权项

1. A computing device to provide dynamic attachment delivery in emails for advanced malicious content filtering, the computing device comprising:
a memory; one or more processors coupled to the memory, the one or more processors executing a communication application in conjunction with instructions stored in the memory, wherein the communication application includes:
a message processing module configured to:
receive a message with an attachment;if the attachment is not a previously assessed attachment, provide the message to a threat protection module;the threat protection module configured to:
detach the attachment from the message and enable the message processing module to deliver the message without the attachment to a recipient;analyze the attachment for potential threats;if the attachment is determined to be sat from potential threats, reattach the attachment to the delivered message; andif the attachment determined to be unsafe, provide a notification associated with the unsafe determination to the recipient.
