Encrypted ZIP files have long been a way to evade any sort of malware detection during transmission.
- mmcgaha 2y agoI doubt it still works but things I needed to get through email I would embed in word documents.
- mplewis9z 2y agoA modern word document file (.docx) is literally just a Zip archive with a special folder structure, so unless your company is scanning word document contents I can’t imagine there’s any issue.
- cogman10 2y agoWould probably still work. There's just too many formats which makes it very hard for a content blocker to really stop. I pity the programmer that has to decode the 1000 versions of xls to find the binary blob that could be a virus.
- telgareith 2y ago1000? No. There's two. Openxml and the original xls. OpenXML can be scanned for issues like any other XML file. Alas, it's more difficult to get excel to accept that it shouldn't delete leading zeros than it is to check a spreadsheet's sus-o-scale.
- cogman10 2y ago1000 is an over exaggeration, but it is not just 2 standards. xls morphed with every version of Microsoft Excel. MS Excel has pretty good backwards compatibility, but making an xls parser is notoriously hard because of the many differences between versions.
- 0cf8612b2e1e 2y agoPretty common in corporate world. Email scanner will helpfully drop all manner of useful files between staff, so make an encrypted zip with simple password.
- slt2021 2y agoyou dont need to even encrypt zip, since encrypted ZIP file can trigger tripwires during transmission. unencrypted zip, but using .docx or .xlsx format is the way to go (the best way is to hide inside one of the openxml tags or xml comments )
- Jerrrrrrry 2y agoencode it with enough filler as to reduce its "entropy" :)
