CSO - Office 365 Phishing attacks create a sustained insider nightmare for IT

In attacks such as these, a victim is likely to click on a message from someone they have an association with. So by abusing the existing trust relationships between vendors and acquaintances, the attackers have a wider pool of potential victims that will offer little push back.... When asked, Lior Gavish, VP Engineering, Content Security Services at Barracuda, also  shared a large list of domains connected to Office 365 Phishing attempts. Barracuda has been tracking Office 365 Phishing campaigns as well, and first reported on them back in August.
