Obtain Juniper Netscreen webshells in batches using Censys
Censys is a new search engine used to search information about networked devices. Security Experts can use it to evaluate the security of their solutions, hackers can use it as a powerful tool to detect attack targets and collect target information in the early stage. Its functionality is very similar to the popular Shodan, but its advantage over Shodan is that it is a free search engine, ini
