In these examples, MOTW was manually set for a ZIP archive file motw-test.zip with Set-MOTW.ps1, then MOTW of an extracted file is displayed with Get-MOTW.ps1. Only ZoneId field of the archive file is inherited and all other fields are ignored.MOTW is propagated only if ZoneId value of the MOTW is 3 (Internet).Only for specific file extensions if the "Propagate Zone Id stream:" option is set to "For Office files" *1.MOTW of the archive file is propagated without modification.The absolute path of the archive file is set for the ReferrerUrl field.ZoneId field of the archive file is inherited.MOTW is propagated only if ZoneId value of the MOTW is 3 (Internet) or 4 (Untrusted sites).Comparison table of MOTW propagation behavior (as of 22 June 2022) Name I previously tested WinRAR with a ZIP archive file that contained only text files, and I misunderstood that WinRAR does not propagate MOTW. I did additional tests with WinRAR 6.11 and confirmed that it propagates MOTW to document files of Word, Excel, and PowerPoint (files of Access and Publisher are not supported). It seems that the supported file types are not documented. *3: Jernej Simončič ( kindly contacted the developer of WinRAR and got the answer that WinRAR propagates MOTW only to Microsoft Office document files. I previously tested Bandizip with a ZIP archive file that contained only text files, and I misunderstood that Bandizip does not propagate MOTW. *2: Accoring to the document of Bandizip, Bandizip propagates MOTW to files with the following file extensions: You can also enable MOTW propagation by setting the registry HKEY_CURRENT_USER\SOFTWARE\7-Zip\Options\WriteZoneIdExtract DWORD to 1.įor 7-Zip CLI, -snz switch is required to propagate MOTW regardless of the option above.

"Extract all" built-in function of Windows Explorer Comparison table of MOTW propagation support (as of 22 June 2022) Name If archiver software does not propagate MOTW, malicious Office documents in archive files can circumvent blocking.Ī question came up: "What archiver software can propagate MOTW to extracted files?" So I tested some archiver software and summarized the result. To block macro of malicious Office document files that are extracted from archive files, an archiver software has to propagate MOTW to extracted files when an archive file has MOTW.

MOTW is stored in Zone.Identifier NTFS alternate data stream. Applications such as web browsers and email clients put MOTW on downloaded files and email attachments that come from the internet. This is a great improvement of defense against malicious Office document files.Īccording to the announcement, whether blocking macro or not is determined based on MOTW (Mark of the Web) attribute of the file.
