+# This resource script will check for vulnerabilities related to
+# programs and services used by developers, including the following:
+#
+# * NodeJS debug (multi/misc/nodejs_v8_debugger)
+# * distcc (unix/misc/distcc_exe)
+# * Jenkins (linux/misc/jenkins_java_deserialize)
+# * GitHub Enterprise (linux/http/github_enterprise_secret)
+#
+# It is worth noting that ONLY CHECKS are performed, no active exploiting.
+# This makes it safe to run in many environments.
