Cyber criminals who have infiltrated one group’s networks are increasingly using a tactic known as “island hopping” to enter other connected networks, security researchers warned Tuesday.
Researchers for the security firm Carbon Black said in a new report that 50 percent of cyberattacks experienced by its clients during the first quarter of 2018 included the island-hopping technique, in which hackers will access one network and then spread out by infiltrating other connected networks.
