The Elland Road boss would not be drawn on naming any targets, but he admitted to being keen on strengthening his options for Leeds' promotion push.
"We're being asked all the time, but until there's something concrete we're not saying anything," Warnock told the club's official website. "That's the way it's got to be this month.
"There's names being thrown about left, right, and centre, and there's names in the newspapers I've never even thought of enquiring about and wouldn't do either."
QPR defender Clint Hill is thought to be on Warnock's radar, while Michael Tonge and Jerome Thomas have returned to Stoke and West Brom respectively following the end of their recent loan deals.
Swansea City's Alan Tate extended his loan to remain at Elland Road until 26 January, and Warnock says offers are on the table for more additions to the Leeds United roster.
"It's a difficult month for managers because you're fending off enquiries all the time, but we are working very, very hard behind the scenes," he added.
"We're trying to bring players in who are better than what we have. We are making enquiries and getting our agenda ready for the next few weeks.
"We've put forward some offers and it'd be nice to think we could get one in by the weekend."
