What is a heartbleed attack?

It allows attackers to steal a server certificate’s private key. Cybercriminals can get the private key and impersonate the server if the server version is vulnerable to Heartbleed. The results can be disastrous, as secure connections to the server are no longer feasible, and personal information is at risk of being revealed.

What is a heartbleed test?

We offer you heartbleed testing with a straightforward approach:

  • Developers get to save around 100 hours per year due to reduced test setup and remediation help right in the scan report.
  • Save on average 40% on your petesting budget and enable constant security posture transparency while decreasing your exposure.

Note: It’s essential that you own and have permission to set the Heartbleed scanner. The tool can generate different HTTP Requests that can be considered attacks (even if they are inoffensive), so consider that you need the authorization to run this scanner.

How the heartbleed tester works?

OpenSSL can be used to create an encrypted connection between two computers. In order to make sure that both computers are available during the communication, the SSL standard provides a protocol called heartbeat. The heartbeat makes sure that both ends can verify that the connection to the other side is still open.

When sending a heartbeat, one of the two ends sends a secret message, including the message’s length. When the other side receives this message, it replies with the same secret message.

For example, Computer 1 sends a heartbeat with the secret message “crashtest” and the length of 9. The second computer receives this message and replies with “crashtest.”

The Heartbleed vulnerability occurred because the length of the secret was not validated. This means if the sender of the connection sends the secret “crashtest” and the length 100, the receiver would return with 100 characters from its local memory. Since sensitive data is stored in the local memory, an attacker could exploit this vulnerability and extract this sensitive data.

Why should I test against heartbleed attacks?

The Heartbleed vulnerability should be taken seriously because it is simple to exploit.  This exposure has been known for a long, and detecting assaults has been difficult. The flaw affects SSL (Secure Sockets Layer) and TLS (Transport Layer Security) protocols used for secure communications and privacy for a wide range of online services, including web, email, and instant messaging. It deceives web servers into sending data stored in their memory, exposing various sensitive personal data and content.

FAQ

Heartbleed Scanner

How to prevent Hearbleed?

First of all, you need to update OpenSSL to the latest version. The following versions fixed the Heartbleed vulnerability:

OpenSSL 1.0.1g
OpenSSL 1.0.0 (not affected)
OpenSSL 0.9.8 (not affected)
E.g., run:

apt-get update; apt-get upgrade # Debian / Ubuntu
yum update # RHeL / CentOS
pacman -Syu # Arch Linux

This step is key because if you’re running vulnerable versions of OpenSSL, the risk of attacks remains.

How did the Heartbleed attack start?

In late 2011, the 31-year-old German engineer Robin Seggelmann contributed the defective Heartbeat functionality to an experimental version of OpenSSL, which lacked a validation method for a variable containing a length. Then its features were sent to OpenSSL for evaluation. However, the developer there missed the flaws as well.

When do the vulnerable versions of OpenSSL start?

Before the problem was found and published, vulnerable versions of OpenSSL had been circulating for more than two years – since March 2012. As a result, computers running previous versions of OpenSSL (before 1.0.1) were unaffected.
