File Transfer Threats: Risk Factors and How Network Traffic Visibility Can Help

Summary: Unit 42 describes file uploads and downloads as routine business functions that carry infrastructure, user, data and availability risks, since uploaded code can execute on the server or client and trigger vulnerabilities in other components or defective libraries. The blog cites Firefox Send, shut down within a year of launch after threat actors used it to spread malware and spear phishing, and notes that Palo Alto Networks App-ID covers more than 352 file-sharing and hosting applications and over 211 applications with file transfer functions.

Why it matters: Most data now sits outside the enterprise, in the cloud, so without traffic visibility over file transfers a careless or malicious insider can cause data loss or a breach that your perimeter controls never see.
