OK, so there is definitely a problem with the Search-UnifiedAuditLog cmdlet in #Microsoft365. Confirmed this in multiple tenants - here's what I'm seeing: 🧵

First, go to -> Audit and perform a new search for all events in a given timeframe (a few hours, total). Have this available for reference.
Next, open PowerShell and connect to Exchange Online:


You ran a search in the Defender portal with a date range of a few hours. Within that same timeframe, pick an even smaller date/time range that has < 100 events. You'll need those timestamps next.

📚 Excellent article on #Phishing techniques targeting #O365 and #Azure🎣 Traditional phishing, device-code authentication, illicit consent grant attacks... it is not easy to make it simple on this topic, and it's the case here!… Image
1️⃣ Obviously, the traditional phishing attack is simple to implement in the absence of multi-factor authent 🔐 We know what to do!
2️⃣ More tricky, device-code authent attack: the attacker’s objective is to get the victim to fill in his device code on the Ms devicelogin page🔥
3️⃣ Conditional access policies can be used to prohibit suspicious connections from devices not under the control of the company👍
4️⃣ The illicit consent grant attack relies on the ability of an attacker to create an app that requires permission to be granted 💣

Changing the entire world is hard but making a better #DigitalWorkplace helps improve our working world. @KurtKragh kicking off #IntraTeam20 #EuroDEX Man on stage in front of mission statement at #IntraTeam20 #EuroDEX
@KurtKragh How do we make it simpler rather than adding complexity?How do we deliver tools to the front-line staff who need it the most?
How do we deliver more in a way that is easier and simpler than what we did last year? @james_steptwo #EuroDEX #IntraTeam20
So @james_steptwo says #intranets aren't sexy (I beg to differ) though he's not afraid of using the i-word #EuroDEX #IntraTeam20 Man on stage in front of a slide about the I word
