How can 'bad actors' be defined in cybersecurity?

In cybersecurity, 'bad actors' are defined as individuals or groups that engage in malicious activities aimed at exploiting systems, stealing sensitive information, disrupting services, or causing harm. This definition captures the intent behind their actions, which is driven by goals such as financial gain, causing chaos, or undermining security. Recognizing these actors is essential in developing effective security strategies to protect systems and data.

The other choices identify groups or individuals that do not fit the malicious motives associated with 'bad actors'. For instance, individuals seeking personal gain through legal means are not involved in harmful or unethical practices. Groups developing software for educational purposes focus on positive outcomes and are typically engaged in legitimate activities. Likewise, technical experts working for cybersecurity firms are tasked with protecting systems against threats, thus playing a defensive rather than an offensive role in the cybersecurity landscape.
