German nuclear plant found riddled with viruses

German nuclear plant found riddled with Conficker, other viruses | Apps and Software | Malware has been running wild at a German nuclear plant in Gundremmingen. Many viruses in nuclear power! The viruses, which include “W32.Ramnit” and “Conficker”, were discovered at Gundremmingen’s B unit in a computer system retrofitted in 2008 with data visualization

PLC teardown

PLCs have a long and storied history, with Allen-Bradley itself coining the term “programmable logic controller” in 1971 when it introduced its version of what was then called the “programmable controller.” For anyone who cut their teeth on ladder logic can testify, PLCs at the time were an elegantly simple solution to an age-old problem:

Arduino PLC

The PLC (Programmable Logic Controller) has been and still is the basic component of the industrial automation world. PLCs are usually pretty expensive pieces of hardware, which led many people who know micro-controllers to come up with their own ideas to implement similar functionality. Arduino is a kind of universal programmable controller, although it is

Ethernet in sensing

In the modern world sensors are used for recording everything from exhaust gas temperatures to the electrical activity in a human heart. Direct wiring methods are commonly used for simple on-off device control, where a circuit is either open or closed. Likewise, digital sensors are usually wired directly to monitoring panels in the world of

Automation systems security issues

Supervisory Control and Data Acquisition (SCADA) systems are used for remote monitoring and control in the delivery of essential services products such as electricity, natural gas, water, waste treatment and transportation. They used to be in closed networks, but nowadays more and more automation and control equipment are connected to Internet. Many of them are
