ASI07: Identity Spoofing
Agent assumes the identity of a user or service without ground-truth attestation.
Last reviewed July 2026
The gap ASI07 closes
In OWASP Agentic Top 10, Identity Spoofing addresses identity. Agent assumes the identity of a user or service without ground-truth attestation. Penaxtra records this control at high severity and establishes its state by exercising it against the running system, so the result reflects observed behavior rather than a documented assertion.
How Penaxtra delivers ASI07
Penaxtra ships adversarial probe families that target identity spoofing directly. Each probe runs against the live endpoint on a schedule, and every triggering response is scored by three independent judges and a meta-judge before it is recorded as a finding under the ASI07 identifier. The OWASP Agentic Top 10 ASI07 identifier is attached when the finding is created, so it appears in the exported evidence pack already mapped to the control. Where the same weakness maps to another framework, the finding carries those control identifiers as well.
ASI07 capabilities
Findings tagged with the OWASP Agentic Top 10 ASI07 identifier
Penaxtra severity for this control (high)
Cross-framework identifiers attached to the same finding where controls overlap
PDF and JSON evidence export with the control identifier attached
ASI07 compliance mapping
Findings for ASI07 carry the OWASP Agentic Top 10 ASI07 identifier along with the corresponding control identifiers in the other frameworks Penaxtra maps, so one result is reflected across each mapped framework.
Frequently asked
What is ASI07 (Identity Spoofing)?
Agent assumes the identity of a user or service without ground-truth attestation. It is a OWASP Agentic Top 10 control; Penaxtra assesses it at high severity.
How does Penaxtra test for ASI07?
Penaxtra ships adversarial probe families that target identity spoofing directly. Each probe runs against the live endpoint on a schedule, and every triggering response is scored by three independent judges and a meta-judge before it is recorded as a finding under the ASI07 identifier.
Does a finding for ASI07 help with an audit?
Each finding is tagged with the OWASP Agentic Top 10 ASI07 identifier and exported in the PDF and JSON evidence pack, so it appears on the auditor control list with the identifier already attached.
