Receiving sharing links from third parties has been the cause of many concerns due for phishing. We’ve added a new Caution Threat Category called External Sharing Link. This category will currently work against SharePoint and OneDrive shared objects but will expand to other third-party services in the future.
...
For Microsoft Tenants that you DO NOT wish to receive an External Sharing Link warning you can simply add their tenant’s name in the “Do not warn about the following trusted Microsoft tenant domains” multi-box and it will suppress the External Sharing Link threat category for that tenant.
The tenant’s name is the subdomain of the tenant address found within an M365 system that ends in .onmicrosoft.com for example, polvocapital.onmicrosoft.com - polvocapital would be entered in the multi-box to suppress the External Sharing Link threat category for Polvo Capitals tenant.
The External Sharing Link threat category by itself is just a caution banner, however, if it’s coupled with additional categories, such as First-Time Sender, it’ll push towards being a dangerous message more quickly than previously. It’s also possible that the External Sharing Link threat category rises to a Danger threat level by itself if it’s coupled with raw suspicious text, such as Contract Bid, Quote Request, Secured Document or other similar terms that are more frequently used in phishing attempts.
Configured your External Sharing Link at the bottom of https://app.inkyphishfence.com/settings/analysis and for our customers that utilize Organizations to manage many teams this setting can be inherited from the Organization profile.
