LIVE CYBER ATTACK LAB #3

Office 365 Man-in-the-Middle Attack Demo

Friday, October 23 | 9:00 am EDT

Our incident response team is seeing an uptick in adversaries using a very tricky man-in-the-middle attack to bypass MFA and breach Office 365 tenants.

 

Our security analyst, Ryan O’Boyle, will give a brief tour of Varonis for Office 365, execute the attack, and show you how to use DatAlert to detect and respond.

About this webinar

Here’s an outline of how the attack works:

  • We trick a user into entering creds into our fake O365 login page (made with evilginx)
  • We make Microsoft send a passcode to the user’s phone
  • User enters their passcode on OUR fake page
  • We hijack the user’s session token
  • Gain access to SharePoint Online environment
  • Exfiltrate data from O365
  • Pivot to on-prem and steal CEO’s emails (because why not?)
