safe-mail: A Docker service used by analysts to extract and inspect suspicious .MSG, .EML, and documents
Everyone, I would like to introduce a new utility for Security Analysts that I built called safe-mail. You can find the repository here: https://github.com/swimlane/safe-mail
safe-mail is a Docker service used by analysts to upload, extract, and inspect suspicious .MSG, .EML, and documents.
safe-mail has an API and a (limited) UI which allows a user to upload and retrieve artifacts generated by safe-mail.
safe-mail has the following features and functionality:
Message Features
• Upload EML and MSG mail messages as well as Microsoft Office documents themselves
• .MSG mail messages are Microsoft binary email format messages - typically from Microsoft Outlook clients
• Generates a PNG of the message itself named {filename}.png
• Extracts all embedded & attached images/attachments within the email message
• Provides a OCR text file of the generated mail message
• Generates a JSON file representing the mail message headers
Attachment/Document Features
• Extracts attachments of mail messages
• Generates an image & PDF of each attachment
• Attempts to extract any identified Macros within attachments and creates a JSON file representing the Macro code base
• PDF Documents will generate output from pdfid & pdfparser tools
• ZIP attachments will extract the zip and return any files within the zip
Enjoy! I hope this helps you all on a daily basis!
