Run malicious server: resend_loop/ans2/ans.py Start BIND: ns1 Send single query to test.com OBSERVED BEHAVIOR The malicious server receives tens of thousands of resend packets within seconds. CPU usage of the named worker thread remains elevated (50–100% of one core) until the default fetch timeout (~10 seconds) terminates the request. Instrumentation during testing confirmed that isc_counter_used(fctx->qc) remains constant (value 1) throughout the entire resend loop. |
