“At 1st look, the SNAKEHOSE get rid of listing appeared to be specifically tailor-made to OT environments due to the reasonably small number of procedures (nevertheless significant number of OT-relevant procedures) discovered with automated instruments for initial triage. Even so, after manually extracting the listing from the purpose that was terminating the procedures, we understood that the get rid of listing utilized by SNAKEHOSE truly targets about 1,000 procedures.”
