Introducing a new phishing technique for compromising Microsoft Office 365 accounts

The ongoing world phishing campaigns towards Microsoft Office 365 have used a variety of phishing techniques. Currently attackers are utilising solid login web sites and OAuth app consents.




In this blog, Genius Fixers introduce a new phishing technique primarily based on Azure AD device code authentication flow. We additionally furnish guidelines on how to detect usage of compromised credentials and what to do to stop phishing using the new technique.

What is phishing?

Phishing is a cybercrime in which a goal or ambitions are contacted by means of email, phone or text message with the aid of someone posing as a authentic group to entice people into offering touchy information such as for my part identifiable information, banking and savings card details, and passwords.

Current phishing techniques:

There are several phishing methods to be used through criminals. Next Genius Fixers quickly introduce two of the most used strategies related to Microsoft Office 365 and Azure AD.

Forged login pages

This is the most common phishing technique, the place attackers have created login pages that imitate legit login screens. When a sufferer enters credentials, attackers can use those to log in the use of victim’s identity.

Lately some state-of-the-art phishing websites have checked the entered credentials in actual time the use of authentication APIs.

This type of phishing can be easily prevented by means of enabling Multi-Factor Authentication (MFA). MFA is covered in all Microsoft Office 365 and Azure AD subscriptions.

 

OAuth consent

Another many times used technique is to lure victims to provide consent to an utility to access their data. These apps are often named to mimic legit apps, such as “0365 Access” or “Newsletter App”:

New phishing technique: system code authentication

Next, Genius Fixers show a new phishing method for compromising Office 365 / Azure AD accounts.

What is System code authentication

According to Microsoft documentation the system code authentication permits users to signal in to input-constrained devices such as a smart TV, IoT device, or printer. To allow this flow, the system has the user visit a webpage in their browser on any other machine to sign in. Once the user signs in, the machine is able to get entry to tokens and refresh tokens as needed.

The procedure is as follows:

1.       A consumer starts an app helping system code glide on a device

2.       The app connects to Azure AD /device code endpoint and sends client_id and resource

3.       Azure AD sends back device_code, user_code, and verification_url

4.       Device indicates the verification_url (hxxps://microsoft.com/devicelogin) and the user_code to the user

5.       User opens a browsers and browses to verification_url, offers the user_code when requested and logs in

6.       Device polls the Azure AD until after succesfull login it gets access_token and refresh_token.

Phishing with system code authentication

The fundamental notion to utilise system code authentication for phishing is following.

1.       An attacker connects to /device code endpoint and sends client_id and resource

2.       After receiving verification_uri and user_code, create an e mail containing a link to verification_uri and user_code, and send it to the victim.

3.       Victim clicks the link, gives the code and completes the sign in.

4.       The attacker receives access_token and refresh_token and can now mimic the victim.
