I’ve been the one identifying the people who use jigglers. Usually it was a manager coming to us to look for a reason to fire a poor employee or a contractor trying to bill a suspiciously large number of hours for the work produced. If it was just poor performance, HR would make us do a PIP and waste 3 months on them. Violating security procedures and falsifying time sheets was an immediate termination. And for the contractors, you need evidence in order to refuse payment.

Btw, if you want to get away with it, don’t use a software or USB one. Get one that interfaces with a regular mouse. Modern cybersecurity software logs every process executed and device connected.
