Industrial Control Systems (ICS) can be found in a variety of highly sensitive environments, and any affect, be it accidental or malicious, will touch upon human lives. From food processing to nuclear plants, our lives would be altered in various ways.
Industrial environments such as power plants nuclear plants, water treatment facilities, manufacturers - especially pharmaceutical ones due to COVID-19 - have become attractive targets, with the manufacturing and energy sectors being the most attacked industries in 2020[1].
Below we present a few strategies that, based on the response readings to modbus/tcp requests, makes it possible to identify the protocol functions that would be implemented in a PLC.
Affected device (Tested): OZW672.06
OZW devices are used for the remote monitoring of building control equipment. For example, for monitoring heating or air conditioning systems.
Climatix - BACnet Communication Card (by Siemens Building Technologies): this device is a module that allows communication via BACnet / IP.
The KMC BACnet Building Controller BAC-A1616BC has a "backdoor" on the embedded web service.
In our laboratory we were able to identify and reproduce a vulnerability which enables the construction and delivery of Modbus protocol frames to...
Today we will be presenting a vulnerability classified as critical found in Omron NS 1.1 / 1.2 / 1.3 which allows remote attackers to bypass authentication via a direct request to the resource "/monitor.html"
We will be reviewing some known vulnerabilities present in various Schneider Electric devices.
Today we are showcasing a few interesting facts regarding the PLC, TM241CE24R (M241) and TM251MESE (M251).
