Rangers have accused fan shareholder group Club 1872 of being "intent on causing damage to the club" and creating a "propaganda war".
The Ibrox club released a statement on Tuesday, just hours after the influential fans' group questioned the "judgement, competence and honesty" of the Rangers executive team, led by Stewart Robertson, James Bisgrove and David Graham.
The furore has erupted in the wake of Rangers' controversial decision to agree to play a friendly match against Old Firm rivals Celtic in Sydney later this year.
Supporters believe the move undermines the intensity of the derby and protested during Sunday's cinch Premiership match away to Dundee by throwing tennis balls and streamers onto the pitch.
Rangers claim the unrest is driven by those with ulterior motives and said the group in question had sparked a "propaganda war".
