description: The following analytic identifies multiple failed multi-factor authentication (MFA) requests for a single user within a PingID environment. It triggers when 10 or more MFA prompts fail within 10 minutes, using JSON logs from PingID. This activity is significant as it may indicate an adversary attempting to bypass MFA by bombarding the user with repeated authentication requests. If confirmed malicious, this could lead to unauthorized access, as the user might eventually accept the fraudulent request, compromising the security of the account and potentially the entire network.
data_source:
    - PingID
search: "`pingid` \"result.status\" IN (\"FAILURE,authFail\",\"UNSUCCESSFUL_ATTEMPT\") | eval time = _time, src = coalesce('resources{}.ipaddress','resources{}.devicemodel'), user = upper('actors{}.name'), object = 'resources{}.devicemodel', reason = 'result.message'| bucket span=10m _time | stats dc(_raw) AS mfa_prompts min(time) as firstTime, max(time) as lastTime values(src) as src by user, reason, _time | `security_content_ctime(firstTime)`| `security_content_ctime(lastTime)` | where mfa_prompts >= 10 | `pingid_multiple_failed_mfa_requests_for_user_filter`"
how_to_implement: Target environment must ingest JSON logging from a PingID(PingOne) enterprise environment, either via Webhook or Push Subscription.
known_false_positives: False positives may be generated by normal provisioning workflows for user device registration.
