Mysterious massive data use for no apparent reason.

Recently about 33GB of data got used on my iMac; it had OCLP Sonoma with two accounts and a supported Monterey OS. Auto updates were all turned off (except for System/security); no smart devices in use; no Zoom etc. running constantly and the WiFi wasn't hacked. The only slight oddity is that the second account seemed as if there might have been an OS update i.e. screens asking for iCloud; Apple ID for App. store etc but it was newish so maybe these were ignored previously. I had also changed a few sharing options.

OCLP is the chief suspect; I have a limited data contract so suddenly losing 30GB for no apparent reason in a few hours is an issue. I suspect some OCLP involvement - anyone heard of similar incidents?
