Allow me to translate: "According to the new revelations, however, contracts for French companies have apparently been intercepted by US secret services for years"
Given hacking means unauthorized access to data, can you explain how intercepting confidential documents in an unauthorized manner could not possibly meet the definition?
Additionally, we know much more detail on Siemens, including the planting of malicious code, which absolutely meets any definition of hacking. [1]
