The incursions, which mostly affected IT providers, took place between 2017 and 2020
France’s cybersecurity watchdog reported the discovery of hacking attacks on French organizations that resemble attacks by a group linked to Russian intelligence.
A report by France’s National Agency for Information Systems Security said hackers exploited a vulnerability in monitoring software sold by Paris-based Centreon.
The agency said it detected intrusions that occurred from late 2017 to 2020.
The agency did not provide the names or number of victims, noting that they were mainly “information technology providers, especially hosting providers.”
It also did not identify the hackers, saying that they acted in a similar way to the Russian cyber spy group, often called Sandworm. It is believed to be affiliated with Russian military intelligence.
