Autosport revealed recently how motor racing's governing body has been ramping up its investigations into team's cost cap submissions.
FIA representatives have been visiting teams to check on their cost cap figures, and some squads have been handed questionnaires demanding more than 100 answers as clarification is sought over their spending.
The FIA has also begun checks into the use by teams of any non-F1 activities.
This comes in the wake of a technical directive, TD45, which outlines that any IP transfer from team's non-F1 elements to their grand prix teams needs to be inside the cost cap.
It was prompted by suspicions that teams were funding non-F1 staff and projects to help find performance gains that were not included as part of their F1 cost cap allowance.
Asked by Autosport if he felt teams had been exploiting this area, Wolff said: "I think so. Yes.
"But the work that the FIA has put into auditing us was big work and big effort, and I have no doubt that they are going to do the same with the other teams. If someone has been cavalier or has cheated, then they're going to find out."
The impact of TD45 has prompted some teams to make infrastructure changes to ensure they fully comply with the new interpretation of the rules.
McLaren boss Andrea Stella said his squad had set up a new company, McLaren Advanced Projects, to ensure any non-F1 work was totally separate from the grand prix team.
