Duo Device Health

Bypass client-side checks for Duo Device Health Application.

WARNING: Multiple failed attempts will lock out you account. If you fail to auth with 2 consecutive attempts, wait for awhile before you try again. Alternatively reset your failed auth attempts by using another device (i.e. a phone) to successfully auth, and then try again.

WARNING: Tested and working on MacOS with Firefox only.

How To

• First make sure actual Duo Device Health app is not running

• Then clone repo

git clone git@github.com:dzflack/duo-device-health.git

• Modify the following fields HealthCheckStartTimestamp, HealthCheckEndTimestamp, DeviceID, DeviceName, HealthCheckLengthMillis in main.go

• Run main.go

go run main.go

• Make sure we are listening, i.e. the following is displayed in terminal:

2020/06/09 10:47:29 Listening on port 53106

• If you are not using the TLS environment variables specified under "Options," use firefox to login to your DUO protected account. (With TLS, you can alternatively use Chrome.)

Options

With the use of environment variables, you can modify this program's behaviour:

• DUO_LOCAL_TLS_CERT and DUO_LOCAL_TLS_KEY - Specify these as filepaths to a cert and key file. For use with Chrome, the cert should be signed by a CA (even if the CA is just you), and that CA's cert should be imported as an Authority in your Chrome settings.
• DUO_LOCAL_PORT - Override port on which to listen.
• DEVICE_ID, DEVICE_NAME - Override DeviceID and DeviceName in the payload to duosecurity.com.
• OS, OS_BUILD, OS_VERSION - Override Os, OsBuild, and OsVersion in the payload to duosecurity.com.
• DUO_CLIENT_VERSION - Override DuoClientVersion in the payload to duosecurity.com.
