I have an observation about this Cyber Security Warning from the National Australia Bank: NAB have DMARC implemented and at this point could have educated recipients how to identify just which domains are used by NAB and can not be spoofed, or how to check if it has been.
Note from the images of the email spoof examples provided by the NAB on their website are tow significant organisations, Australia Post and ASIC. The Australia Post spoof was using a dodgy and random unrelated from domain, thanks to DMARC. The Australia and Investment Securities Commission does not have DMARC and therefore the criminals have used thed domain in the From address.
- Australia Post has DMARC and could have been referenced by the NAB in their warning;
- The Australia and Investment Securities Commission does not have DMARC!
When it comes to transnational messaging and email marketing organisations must protect their customers and brand.
