Greatness PhaaS Adds Device Code Phishing to Bypass MFA
- Engineer — Plan: Device code flow abuse bypasses MFA by design; audit your identity provider (Entra ID, Okta) and restrict or disable the OAuth Device Authorization Grant for users/apps that don’t require it — block or conditional-policy-gate this flow this quarter.
- SOC/IR — Plan: No IOCs provided, but Greatness PhaaS commoditizing device code phishing signals growing campaign volume; build detections in Entra/Okta logs for unexpected device code authorization requests, particularly outside normal device-enrollment windows.
- Leader — Learn: MFA bypass techniques are now packaged in commercial crimeware toolkits, eroding the assurance value of standard MFA — useful context for risk register updates and for evaluating phishing-resistant auth (FIDO2/passkeys) as a strategic control.
