Which harmful insider uses technical knowledge to exploit network weaknesses for profit?

The term "Professional" refers to an insider who possesses technical expertise and intentionally exploits their knowledge of the organization's systems and networks to create harm for personal gain. This type of insider is often well-versed in the network's architecture, making them capable of pinpointing vulnerabilities that may otherwise go unnoticed.

These individuals tend to operate with a clear understanding of the potential consequences of their actions, often leveraging their professional skills to achieve unethical objectives, such as stealing sensitive information, manipulating data for financial gain, or causing disruptions that benefit them personally.

In contrast, the other categories lack the malicious intent or technical acumen associated with the term "Professional." For example, "Malicious" might imply intent but does not specifically capture the technical knowledge aspect. "Negligent" implies a failure to exercise reasonable care or caution, lacking the deliberate exploitation of skills, while "Compromised" suggests that the insider's actions are not inherently malicious or driven by technical expertise; instead, it indicates that someone else has taken control of their account or access rights, effectively eliminating the element of intentional exploitation.

Thus, "Professional" distinctly highlights the combination of both technical skills and malicious intent to exploit network vulnerabilities for profit.
