An extraordinary amount of Cryptolocker outbreaks were due to .docx files containing macros.
Yes, it has a default behaviour of "prompt to execute macros", but it happily shows the advice in the malicious document to "please click yes at this prompt to get a free iPhone", at which point the majority of users click "yes".
- mavhc 10y ago.docx files can't contain macros
- technion 10y agoCorrection: It's .doc files I've seen the majority of this behaviour in.
- neko_koneko 10y ago.docx files could contain macros just fine.
- emodendroket 10y agoThey cannot. Anything that has macros has to be docm.
- neko_koneko 10y agoSorry, my bad. I meant files in OOXML format.
- floatboth 10y agoI think Swift on Security posted a tweet about this a while ago, with a screenshot of completely banning all Office macros via group policy.
- emodendroket 10y agoOffice macros are really useful, though.
