Snake / Ekans), which was developed to execute its payload only right after halting a sequence of procedures that integrated some industrial program from vendors these as Standard Electric powered and Honeywell.
“At initial look, the SNAKEHOSE get rid of list appeared to be precisely tailored to OT environments thanks to the rather little quantity of procedures (nonetheless substantial quantity of OT-linked procedures) identified with automatic tools for original triage. Having said that, right after manually extracting the list from the purpose that was terminating the procedures, we realized that the get rid of list utilized by SNAKEHOSE basically targets above one,000 procedures.”
