It is understood that there are fears in the Whitehall that Russia could release doctored quotes of their comments for propaganda purposes. Nadine Dorries, the culture secretary, was also unsuccessfully targeted, The Guardian reported.
The UK Prime Minister's official spokesperson said: "The Russian state was responsible for the hoax telephone calls made to UK ministers last week.
"This is standard practice for Russian information operations and disinformation is a tactic straight from the Kremlin playbook to try to distract from their illegal activities in Ukraine and the human rights abuses being committed there."
Defence secretary Wallace has publicly acknowledged that he had been targeted shortly after his call on Thursday in an attempt to get ahead of any attempt by Moscow to circulate footage from it.
