#Connected by tcp hack code
An attacker sends the MODBUS request packet with function code 43 to all systems in the network and gathers intelligence that may be helpful in future attacks Modbus vulnerabilities Additional information may also be provided in optional fields.

This function is typically implemented only in serial devices.Īnother diagnostic command attacker can use is Read Device Identification as an attempt to gather information on Modbus device: A MODBUS request packed with function code 43 Read Device Identification will cause a MODBUS server to return the vendor name, product name, and version number. Modbus attacksĪn Attacker can start his attack in reconnaissance phase by scanning the network trying to find Modbus devices with Modbus diagnostic commands: Clear Counters and Diagnostic Register: a request sent to PLC, with function code 8 (0x08) and subfunction code 10 (0x0A), will cause the target server to clear its counters and the diagnostic register.
