Centreon, the maker of the IT monitoring software exploited by Russian state hackers to infiltrate French companies' networks, said today that only organizations using obsolete software were compromised.

Today's Centreon press release comes after a report released on Monday by ANSSI, the French national cyber-security agency, describing a series of attacks that resulted in multiple French IT providers getting breached over four years.
