Bad actors continue to create malicious emails that are convincing innocent workers at healthcare and other organizations the messages are authentic. And many workers click on them, starting a stream of problems. This is why it's up to CISOs and other cybersecurity professionals to train workers how to identify phishing emails and not click on them or download their malware-infested attachments. Danville, Pennsylvania-based Geisinger has had great success with its anti-phishing training, lowering the click rate on malicious emails by 50%.
