“The attackers used misleading practices this kind of as developing a phony LinkedIn profile to look credible and custom-made command-and-management (C2) centers for each individual concentrate on, exploiting authentic solutions for illicit things to do.”
The npm deals have given that been documented and taken down. The names of the packages were being not disclosed.
