Name:PingID New MFA Method Registered For User id:892dfeaf-461d-4a78-aac8-b07e185c9bce version:8 date:None author:Steven Dick status:production type:TTP Description:The following analytic detects the registration of a new Multi-Factor Authentication (MFA) method for a PingID (PingOne) account. It leverages JSON logs from PingID, specifically looking for successful device pairing events. This activity is significant as adversaries who gain unauthorized access to a user account may register a new MFA method to maintain persistence. If confirmed malicious, this could allow attackers to bypass existing security measures, maintain long-term access, and potentially escalate their privileges within the compromised environment. Data_source:
-PingID
search:`pingid` "result.message"="Device Paired*" result.status="SUCCESS" | rex field=result.message "Device (Unp)?(P)?aired (?<device_extract>.+)" | eval src = coalesce('resources{}.ipaddress','resources{}.devicemodel'), user = upper('actors{}.name'), reason = 'result.message' | eval object=CASE(ISNOTNULL('resources{}.devicemodel'),'resources{}.devicemodel',true(),device_extract) | eval action=CASE(match('result.message',"Device Paired*"),"created",match('result.message', "Device Unpaired*"),"deleted") | stats count min(_time) as firstTime, max(_time) as lastTime by src,user,object,action,reason | `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)` | `pingid_new_mfa_method_registered_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.
