The dark web ecosystem continues to evolve as a place where cybercriminals can sell and access stolen data, purchase black-market items such as guns, drugs and hacking software, and connect with like-minded individuals. As is the case in any supply-and-demand scenario, since there remains a strong demand for these and other items, the dark web will remain a popular hub for the foreseeable future. That, in turn, puts security professionals and their enterprises in the position of needing to gain a deeper understanding of the dark web and how to mitigate its various risks.
