DocBleach - Content Disarm and Reconstruction(CDR) - Open Source tool

DocBleach:

              is an advanced Content Disarm and Reconstruction open source software. Its objective is to remove misbehaving dynamic content from your Office files, or everything that could be a threat to the safety of your computer.




                                    DocBleach allows you to sanitize your Word, Excel, PowerPoint, PDF, ... documents. This repository contains the DocBleach Web API, packaged as a docker service. Two clicks and you'll feel safer.


Let's assume your job involves working with files from external sources, for instance reading resumes from unknown applicants. You receive for example a .doc file, your anti-virus doesn't detect it as harmful, and you decide to open it anyway. You get infected. You can use DocBleach to sanitize this document: chances are you don't get infected, because the dynamic content isn't run.

Howto's

To build DocBleach, use Maven:
$ mvn clean package
...

Threat Hunting Tool - Bro (Zeek) Network Security Monitor

Bro (Zeek) - Threat Hunting Tool:

A powerful framework for network traffic analysis and security monitoring.Bro is a passive, open-source network traffic analyzer. It is primarily a security monitor that inspects all traffic on a link in depth for signs of suspicious activity. More generally, however, Bro supports a wide range of traffic analysis tasks even outside of the security domain, including performance measurements and helping with trouble-shooting.



Note that "Zeek" is the new name of what used to be known as the "Bro" network security monitoring system.


Key Features

  • In-depth Analysis Zeek ships with analyzers for many protocols, enabling high-level semantic analysis at the application layer.
  • Adaptable and Flexible Zeek's domain-specific scripting language enables site-specific monitoring policies and means that it is not restricted to any particular detection approach.
  • Efficient Zeek targets high-performance networks and is used operationally at a variety of large sites.
  • Highly Stateful Zeek keeps extensive application-layer state about the network it monitors and provides a high-level archive of a network's activity.

Malicious Software Removal Tool (MSRT) :

                                                                 helps keep Windows computers free from prevalent malware. MSRT finds and removes threats and reverses the changes made by these threats. MSRT is generally released monthly as part of Windows Update or as a standalone tool available here for download.



Use this tool:
  • If you have automatic updates for Windows turned off. Windows Update automatically downloads and runs MSRT in the background.
  • If you suspect an infection from prevalent malware families
  • To complement your antimalware product.

MSRT targets prevalent malware families only.

Download Link :

https://www.microsoft.com/en-us/download/details.aspx?id=16

Microsoft Safety Scanner:


is a scan tool designed to find and remove malware from Windows computers. Simply download it and run a scan to find malware and try to reverse changes made by identified threats.

Free / Open-Source tools for Kubernetes Security Audit

kube-hunter:

                   is an open-source tool that hunts for security issues in your Kubernetes clusters. It’s designed to increase awareness and visibility of the security controls in Kubernetes environments.



kube-hunter is available as a container (aquasec/kube-hunter), and we also offer a web site at kube-hunter.aquasec.com where you can register online to receive a token allowing you see and share the results online. You can also run the Python code yourself as described below.

Contribute: We welcome contributions, especially new hunter modules that perform additional tests. If you would like to develop your own modules please read Guidelines For Developing Your First kube-hunter Module.





Ref link : https://kube-hunter.aquasec.com/

kube-bench:

                  is a Go application that checks whether Kubernetes is deployed securely by running the checks documented in the CIS Kubernetes Benchmark.

"An objective, consensus-driven security guideline for the Kubernetes Server Software."


Note that it is impossible to inspect the master nodes of managed clusters, e.g. GKE, EKS and AKS, using kube-bench as one does not have access to such nodes, although it is still possible to use kube-bench to check worker node configuration in these environments.

Tests are configured with YAML files, making this tool easy to update as test specifications evolve.


Sample Output:
 





CIS Kubernetes Benchmark support

kube-bench supports the tests for Kubernetes as defined in the CIS Benchmarks 1.0.0 to 1.4.0 respectively.

CIS Kubernetes Benchmark kube-bench config Kubernetes versions
1.0.0 1.6 1.6
1.1.0 1.7 1.7
1.2.0 1.8 1.8-1.10
1.3.0 1.11 1.11-1.12
1.4.0 1.13 1.13-

By default kube-bench will determine the test set to run based on the Kubernetes version running on the machine.

Gorsair - Docker API Penetration Testing Tool

Gorsair

                is a penetration testing tool for discovering and remotely accessing Docker APIs from vulnerable Docker containers. Once it has access to the docker daemon, you can use Gorsair to directly execute commands on remote containers.

Gorsair hacks its way into remote docker containers that expose their APIs.




Exposing the docker API on the internet is a tremendous risk, as it can let malicious agents get information on all of the other containers, images and system, as well as potentially getting privileged access to the whole system if the image uses the root user.


Install

From a release

Set the:
  • GORSAIR_VERSION to whatever release you are interested in
  • OS to your operating system (linux, windows or darwin)
  • ARCH to your architecture (amd64, arm, or ppc64le)
And then run the following command to install gorsair.
curl https://github.com/Ullaakut/Gorsair/releases/download/$GORSAIR_VERSION/gorsair_$OS_$ARCH --output /usr/local/bin/gorsair

From the sources

  • Make sure that you have a go version that supports modules (versions 1.11 and above)
  • Make sure that your environment contains the GO111MODULE variable set to on
  • Run go build -o /usr/local/bin/gorsair cmd/*.go from the root of this repository

Command line options

  • -t, --targets: Set targets according to the nmap target format. Required. Example: --targets="192.168.1.72,192.168.1.74"
  • -p, --ports: (Default: 2375,2376) Set custom ports.
  • -s, --speed: (Default: 4) Set custom nmap discovery presets to improve speed or accuracy. It's recommended to lower it if you are attempting to scan an unstable and slow network, or to increase it if on a very performant and reliable network. You might also want to keep it low to keep your discovery stealthy. See this for more info on the nmap timing templates.
  • -v, --verbose: Enable more verbose logs.
  • -D, --decoys: List of decoy IP addresses to use (see the decoy section of the nmap documentation)
  • -e, --interface: Network interface to use
  • --proxies: List of HTTP/SOCKS4 proxies to use to deplay connections with (see documentation)
  • -S, --spoof-ip: IP address to use for IP spoofing
  • --spoof-mac: MAC address to use for MAC spoofing
  • -v, --verbose: Enable verbose logging
  • -h, --help: Display the usage information

How can I protect my containers from this attack

  • Avoid putting containers that have access to the docker socket on the internet
  • Avoid using the root account in docker containers
