Microsoft upgraded their EOP anti-spoofing capabilities inside Office 365, which is good, but they didn’t tell anyone. The first users knew was when they started to receive messages stamped with “the sender failed our fraud detection checks” – something that is never assuring. This only applies to ATP customers, but it’s not the first time Microsoft has failed to communicate important news.
Microsoft launched Advanced Threat Protection for SharePoint Online, OneDrive for Business, and Teams on December 5. It’s good to have extra anti-malware capabilities, but ATP requires Office 365 E5 or an extra add-on, so it might be out of the reach of some tenants. And it’s all about SharePoint – Teams is just there because Teams can store documents.
Take a look at the steps which, when taken together, should minimize your risks of being successfully attacked by ransomware such as WannaCrypt, CryptoLocker, and a plethora of other variants that are ravaging businesses of all sizes around the world.
Microsoft introduced the Safe Attachments feature as part of its Advanced Threat Protection (ATP) offering in 2015. ATP is an option for Exchange Online Protection (EOP). It is included in the Office 365 E5 plan and can be licensed as an add-on for $2/user per month for other Office 365 plans. Now Safe Attachments can handle dynamic delivery and the improvement is noticeable.
