Sorry for the (extremely) delayed response. SNMP specifies that malformed packets are dropped, so we don't really consider the received packet as a response. We can't know the difference between a broken agent and a spoofed response sent by a bad actor. We are reporting what actually happened - we timed our waiting for a valid response from the agent.
