In this article “The maker of an industrial control system designed to be used with so-called smart grid networks disclosed to customers last week that hackers had breached its network and accessed project files related to a control system used in portions of the electrical grid.
Telvent, which is owned by Schneider Electric, told customers in a letter that on Sept. 10 it learned of the breach into its network. The attackers installed malicious software on the network and also accessed project files for its OASyS SCADA system, according to KrebsOnSecurity, which first reported the breach.
According to Telvent, its OASyS DNA system is designed to integrate a utility’s corporate network with the network of control systems that manage the distribution of electricity and to allow legacy systems and applications to communicate with new smart grid technologies.”
