NST Heartbleed Detection

Overview

This page shows how to use NST and nmap to detect the heartbleed vulnerability. Heartbleed is a software bug in the open-source cryptography library OpenSSL, which allows an attacker to read the memory of the host computer, allowing them to retrieve potentially privacy-sensitive data.

Heartbleed Detection - NST Pro System

NST 20
SVN: 5804

NST Pro users need to first update their NST system to get the latest version of nmap (i.e., v6.45 or greater) from the NST Pro repository. This release contains the nmap NSE (Nmap Scripting Engine) script: "/usr/share/nmap/scripts/ssl-heartbleed.nse" written by Patrik Karlsson which is based on code authored by Jared Stafford.
