T1430.002: Impersonate SS7 Nodes
Adversaries may exploit the lack of authentication in signaling system network nodes to track the location of mobile devices by impersonating a node.[1][2][3][4][5]
By providing the victim’s MSISDN (phone number) and impersonating network internal nodes to query subscriber information from other nodes, adversaries may use data collected from each hop to eventually determine the device’s geographical cell area or nearest cell tower.[1]

Executive priority
T1430.002: Impersonate SS7 Nodes is an official MITRE ATT&CK technique. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.
Technical view
Security teams should validate T1430.002: Impersonate SS7 Nodes by reviewing the official ATT&CK relationships, mapped tactics (collection, discovery), supported platforms (Android, iOS), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
- Endpoint process, command-line, and script execution logs
Detection direction
- Validate whether T1430.002: Impersonate SS7 Nodes appears in your detection coverage and tabletop scenarios.
- Use the object to align executive risk language with SOC, incident response, and detection engineering work.
- Do not treat ATT&CK relationship context as attribution without corroborating evidence.
Mitigation priorities
- Map the object to existing controls and identify missing telemetry or response ownership.
- Prioritize mitigations that reduce exposure on the listed platforms and tactics.
- Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits
Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.
This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

How security teams should use this page
Treat this object as behavior context, not an attribution claim. Validate the related groups, software, data sources, and mitigations against official ATT&CK relationships and your own telemetry before making control-coverage decisions.

S0602: Circles
Circles reportedly takes advantage of Signaling System 7 (SS7) weaknesses, the protocol suite used to route phone calls, to both track the location of mobile devices and intercept voice calls and SMS messages. It can be connected to a telecommunications company’s infrastructure or purchased as a cloud service. Circles has reportedly been linked to the NSO Group.[1]

Object version and sync metadata
The fields below describe the current mirrored snapshot. When Glexia retains multiple ATT&CK source imports, you can open the table to compare the same object across releases (hashes and MITRE timestamps). For MITRE’s own release notes and roadmap, see ATT&CK resources — Updates.
Imported snapshots across ATT&CK releases(2)
| Release | Bundle imported | Object version | Modified | Status | Raw hash |
|---|---|---|---|---|---|
| 19.2 | 1.1 | Current bundle | bdcfe9b8a94b… | ||
| 19.1 | 1.1 | Older bundle | bdcfe9b8a94b… |
Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
