Wp Admin Plugin Upload Backdoor Zip
Detects a WordPress admin plugin ZIP upload to wp-admin/update.php?action=upload-plugin only when correlated with high-risk context: the observed wp2shell_ plugin naming convention, evidence of a just-created/unfamiliar administrator account (wp-admin/user-new.php activity in the same capture), or the upload occurring immediately after REST API batch-route/SQLi anomalies (wp-json/batch/v1, author__not_in) tied to CVE-2026-63030 and CVE-2026-60137. Routine plugin uploads by established administrators without these correlating indicators are excluded.
