When the module is required, an IIFE at the top of the file uses child_process.execSync to run host reconnaissance commands (id, whoami, uname -a, ifconfig/ip addr, cat /etc/hosts) and sends the command output along with a beacon (Node version, platform, pid) via plain-HTTP GET requests to a hardcoded attacker-controlled endpoint at http://dxpoc.gt.tc/callback.php/ef9ea0e191006f3cc6670720c99c26f3. The package self-labels the beacon as 'rce-poc'. The shape is a dependency-confusion / typosquat payload: a benign-sounding public package shadows Wix-internal registry names so that a build pipeline resolving these names from the public registry executes the reconnaissance payload with the installer's privileges on module load.\n\n---\n\nCredit: OpenSSF ([source](","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.389Z","source_updated_at":"2026-10-05T00:30:48.000Z","source_disclosed_at":"2026-10-05T00:30:40.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T23:13:05.881Z"}],"next_cursor":null,"snapshot_revision":"44495"}
