This guide provides step-by-step instructions for deploying StreamSets Data Collector version 5.7.1 in a Docker container and creating a simple pipeline to connect to a WebSocket and store the received data locally.
The intention of this document is to show you the basics of how to download the WhoisXML API's NRD2 data feed provided by WhoisXML API to a GCP Cloud Storage bucket by leveraging a serverless Cloud Functions. GCP Cloud Functions acts as a serverless compute service that allows you to write and execute code without provisioning or managing servers. GCP Cloud Storage is an object storage service for storing and retrieving files. This document will guide you through the process of configuring both GCP Cloud Functions and a GCP Cloud Storage bucket.
The intention of this document is to show you the basics of how to download the WhoisXML API's NRD2 data feed provided by WhoisXML API to an AWS S3 bucket by leveraging a serverless Lambda function. AWS Lambda functions act as a serverless compute service that allows you to write and execute code without provisioning or managing servers. AWS S3 is an object storage service for storing and retrieving files. This document will guide you through the process of configuring both AWS Lambda and an AWS S3 bucket.

WhoisXML API offers, via API calls, a lot of information on domains or IP addresses that is very useful for a number of applications, including cybersecurity investigations, domain appraisal or system administration. Imagine that one is given a long list of domain names, and one is interested in each domain's details, e.g., WHOIS or website categories, etc. In each API call, a single domain name is sent, and its data is returned in JSON format. (Some of the APIs of WhoisXML API offer bulk lookups, too, but we will not deal with this possibility here.) To get an overview of the data, analysts often prefer to have everything in a single csv file; one line for each domain. This can be opened by popular office spreadsheets like Excel or LibreOffice Calc, or sent to other kinds of processing.
Typosquatting and related types of cyber threats, such as domain squatting, phishing campaigns, IDN homoglyph attacks, etc., cause significant harm and incur financial loss, so it is vital to be vigilant and fight against these malicious threats.
Secure shell (ssh) is the typical tool for getting secure command-line access to Linux (and other Unix flavor) systems. Notably, most Linux-based servers are administered remotely via ssh access. Hence the security of the ssh service is of paramount importance, especially since it is often a very attractive part of the attack surface of an organization.
The present blog provides a discussion on setting up efficient firewall rules for the ssh service, and extending the whitelist easily with the help of WhoisXML API's IP Netblocks API. The method also works for other services using inbound tcp connections. We discuss a typical iptables firewall on a Linux system. Basic expertise in Linux tools and firewalls is assumed. The recipe works as it is, or with minor modifications also on other systems.
IP addresses are straightforward input data for IT security investigations: they are technically necessary for nodes of the Internet to communicate. Hence, if they are not deleted in some tricky way after cybercrime has been committed, or they are to be found in any of the logs before the commitment, they help a lot to unfold what has actually happened.
IBM Xforce exchange is a forum reporting many security incidents that are relevant for those who are in charge of maintaining IT security. In the present blog we shall pick one of their reports and check how we can extend the given information with WhoisXML APIs using PowerShell which comes installed on Windows and can be used on Linux and Mac OS X, too. We assume lower intermediate skills of PowerShell programming to follow the description below.
