I'm going to continue piggybacking onto this thread as it deals with Clamav's non-discovery of the malware attached to messages with the subject "Invoice ...". Although, I don't know if this is the same type of attachment.
The attachments I've been getting are .docx file named as .doc files. In examining the contents of these archives I find: $ unzip -l InvoiceZGC3020188.doc Archive: InvoiceZGC3020188.doc Length Date Time Name --------- ---------- ----- ---- 1510 01-01-1980 00:00 [Content_Types].xml 590 01-01-1980 00:00 _rels/.rels 1226 01-01-1980 00:00 word/_rels/document.xml.rels 5097 01-01-1980 00:00 word/document.xml 5424 01-01-1980 00:00 word/media/image1.emf 132276 01-01-1980 00:00 word/media/image2.png 6850 01-01-1980 00:00 word/theme/theme1.xml 6144 01-01-1980 00:00 word/embeddings/oleObject1.bin 4809 01-01-1980 00:00 word/settings.xml 1299 01-01-1980 00:00 word/fontTable.xml 576 01-01-1980 00:00 word/webSettings.xml 995 01-01-1980 00:00 docProps/app.xml 29121 01-01-1980 00:00 word/styles.xml 732 01-01-1980 00:00 docProps/core.xml --------- ------- 196649 14 files "Normal" .docx files do not have the oleObject1.bin as an archive members. I do have ScanOLE2 and OLE2BlockMacros enabled. So why isn't clamav detecting this oleObject1.bin member? (To where should I submit a sample of this attachment?) --Mark -----Original Message----- From: Mark Foley <mfo...@novatec-inc.com> Date: Wed, 15 Nov 2017 13:18:23 -0500 Organization: Novatec Software Engineering, LLC To: clamav-users@lists.clamav.net I'm having this same issue. The problem as I see it is that the .doc attached to these "Invoice" message is encrypted and clamav does not see what's inside. I'm discussing this encrypted attachment issue in my thread, subject: "password protected encrypted .docx files". I'm continuing to research this. --Mark On Wed, 15 Nov 2017 15:09:59 -0300 Emanuel <emanuel.gonza...@donweb.com> wrote: > Other virus not detected > > https://www.virustotal.com/#/file/6b7b11077b2bcdbce94eff73722a4f78103d2e87bd4331654bc65c0daeb176dd/detection > > > El 14/11/17 a las 09:52, Emanuel escribió: > > Scan the attachment, clamav not detect this file. > > > > > > El 14/11/17 a las 09:51, Al Varnell escribió: > >> You mentioned two attachments.
