Linode dynamic DNS updating script
#!/bin/bash
# Modified by Chris Richardson (https://github.com/christr and https://twitter.com/christr77) on 09/20/2020
# Previous versions of this script don't work because they hadn't been updated since 2012. There are now more steps involved to set this up.
# This script update is based on information found here: https://developers.linode.com/api/v4/domains-domain-id-records-record-id/#put
# You first must find out the domain ID and resource ID numbers. In order to do this follow the steps below.
# 1. Create a Linode API Key through your account profile at https://cloud.linode.com/dashboard. Give it rights to read/write to domains only.
# 2. From a shell run the following command: LINODE_API_KEY=[insert API key from step 1 here]
# 3. Run the following command to get the domain ID number for the domain you want to manage: curl -H "Authorization: Bearer $LINODE_API_KEY" https://api.linode.com/v4/domains/

The MS-MSDT 0-day Office RCE Proof-of-Concept Payload Building Process

MS-MSDT 0-day Office RCE

MS Office docx files may contain external OLE Object references as HTML files. There is an HTML sceme "ms-msdt:" which invokes the msdt diagnostic tool, what is capable of executing arbitrary code (specified in parameters).

The result is a terrifying attack vector for getting RCE through opening malicious docx files (without using macros).

Here are the steps to build a Proof-of-Concept docx:

  1. Open Word (used up-to-date 2019 Pro, 16.0.10386.20017), create a dummy document, insert an (OLE) object (as a Bitmap Image), save it in docx.

Just another shellcode execution technique :)
