Seventy-two hours before the attacks in Paris began, messages including images of weapons and the Eiffel Tower began to appear on social media.
Fox News reports four credible social media accounts linked to ISIS shared the content, which also included blessings for the attackers.
The messages translate to "God bless you in your mission" and "support the deployment".
There is also a reference to "our sister", which may suggest that an operative or member of the support group is a woman.

ISIS has claimed responsibility for the massacre in which 129 were killed and hundreds more injured by a coordinated attack of bombs and shootings.
There is widespread concern over how French intelligence did not pick up any communications which foreshadowed the massive terror attack.
In response to this New Zealand Prime Minister John Key has said ISIS was now much more aware of which technologies could be intercepted.
He said it was "possible" that the 40 people on New Zealand's terror watch list were also using highly encrypted technology, but he would not comment on specific communications or apps they could be using.
Intelligence officials had told him that New Zealand spies were now faced with bigger obstacles in monitoring suspects.
"The amount of dark communications that are not [detectable] by our agencies is increasing," he said.
New Zealand's Security Intelligence Service (SIS) and Government Communications Security Bureau (GCSB) are now under review.
