What it detects

This rule detects creation of an onlogon scheduled task whose action executes a binary staged in ProgramData as used by the NetSupport actor for persistence under a masqueraded task name and this matters because legitimate onlogon tasks rarely launch executables from ProgramData and this pattern reflects malware establishing user triggered persistence.
