Siemens, a German-based engineering company, has made a program available to its customers that can detect and remove malware infecting its software which is used to control power grids, factories and oil refineries. However, the firm warned that disinfecting the system could interfere with sensitive operations.
The firm is distributing Sysclean, a product made by Trend Micro.
“As each plant is individually configured, we cannot rule out the possibility that removing the virus may affect your plant in some way,” Siemens warned.
The company also advised clients to keep all anti-virus software updated because “There are currently some new derivative versions of the original virus around.”
The virus appears to spread through infected USB drives.
