Shodan is a search engine that has been used to expose several significant data repositories in the past many of them covered here on Salted Hash. Check Point’s advisory is warning customers to block Shodan because hackers use it and sensitive information has been discovered via the platform. There are no mentions of regular security scans in the advisory, and there are no notes that state blocking scanners isn’t really going to fix anything. Instead, blocking Shodan won’t stop access to your poorly written Web app, or your publicly exposed admin interface.”]
