B01 - Attachment 0005 - Blocked File Extensions.pdf

This document is an attachment listing blocked file extensions for contract opportunity W519TC-27-Q-LUMB. The attachment serves as a technical specification or security requirement defining file types that are prohibited from submission or use within the contract performance. The blocked extensions encompass 73 file types across multiple categories, including executable files (*.exe, *.com, *.bat, .cmd), scripting languages (.js, *.vbs, *.wsf, .wsh), web-related formats (.htm, .html, .xml), database files (.mdb, .mde, .mdz), Microsoft Office macro-enabled documents (.mht, .mhtml), installation files (.msi, .msp), and compressed archives (.zip). Additionally, the list includes various other potentially harmful file types such as shortcuts (.lnk), dynamic libraries (.dcr, .dir), help files (.hlp, .chm), and certificate-related files (.crt, *.crl).

This blocked file extension list appears to be a security control mechanism designed to prevent the transmission or execution of potentially malicious or unwanted file types during contract performance, likely governing submissions, documentation exchanges, or system interactions between the contractor and the federal agency. The comprehensive nature of the restrictions suggests heightened security protocols are required for this procurement.
