  • Detecting Malicious Email Campaigns with Unique but Similarly-Spelled Attachments

    Issued US 12177246 B2

    Email logs from network appliances are retrieved, filtered, normalized, and converted into field-based organized data for comprehensive analysis. Cluster analysis is performed. Filenames of email attachments are transformed into numerical vectors and a cosine similarity termset analysis is performed on the numerical vectors. Data is organized into time bins for burst detection. Statistical analysis is performed on the time bins. Pattern recognition is performed to identify alphanumeric…

    Email logs from network appliances are retrieved, filtered, normalized, and converted into field-based organized data for comprehensive analysis. Cluster analysis is performed. Filenames of email attachments are transformed into numerical vectors and a cosine similarity termset analysis is performed on the numerical vectors. Data is organized into time bins for burst detection. Statistical analysis is performed on the time bins. Pattern recognition is performed to identify alphanumeric similarities in the filenames of the attached files in order to detect malicious email campaigns. Machine learning may be used to optimize the cosine similarity threshold and other query variables, and to update existing cybersecurity filters and firewalls. Mitigation can be performed to remove malicious emails that were delivered to recipient mailboxes.

    “In my time with Mark, I found him to be very professional and eager to learn while adhering to the highest ethical standards. He is outgoing and able to build professional relationships that he can utilize to solve or get direction on any problem he cannot resolve on his own. His documentation of processes and procedures are excellent and an asset to any new team members to assist in shortening their learning curve. He has consistently shown he enjoys challenges and usually has different back out plans, depending where a failure occurs. He has strong trouble shooting skills and to my knowledge, never walked away from an opportunity to help. Mark is an asset of the highest caliber.”
