Top 5 Best TV Series Based On Hacking & Technology 2018

Top 5 Best TV Series Based On Hacking And Technology 2018

Well, if you are a tech fanatic then you will love watching TV shows which are based on hacking and technology. If you are a tech geek, then you will know that hacking stuff in movies/serials always generates glamor and mystery and adds that special oomph factor to the movie or Tv SHOW.

However, there are not much movies/ or TV serials made on hacking and technology. Technology is rapidly becoming the key point in human lives. The previous year we have seen how hackers had made their marks on giant companies. So, in this article, we are going to discuss top TV shows which have to hack as the central theme. So, have a look at the list.

#1 Mr. Robot

Mr. Robot: Best TV Series Based On Hacking & Technology 2018

Well, the reason why I listed Mr. Robot on the top is because this show has millions of followers and this is the first show that portrays an elite hacker. The elite hacker group uses computers, smartphones and many other technologies to penetrate secure network to take down evil corporation while being anonymous. The show displays the life of a young programmer named Elliot who works as a cyber-security engineer and a vigilante hacker by night.

#2 Silicon Valley

Silicon Valley

This TV series displays the tech and hacking with a bit of comic touch. The series shows the competition between techies in the high-tech gold rush of modern Silicon Valley. What's more interesting is the people who are more qualified are least successful whereas underdogs are making it big. This show is running successfully for three years now.

#3 The IT Crowd

The IT Crowd

The IT Crowd is very popular series and is running successfully for eight years from 2006 to 2013. It is not like Mr.Robot it has its moments of hacks. The series shows the comedic adventures of a rag-tag group of technical support workers at a large corporation.

#4 Person Of Interest

Person Of Interest

It is one of the best TV series made till now. You will get to see the humor, twists, and lots of other things. In this show and intelligent programmer built and AI (Artificial intelligence) that helps to stop the crimes in the city. The show will definitely give you chills.

OWASP Web 2.0 Project Update

Some of you likely recall the talk back in 2016 or so of updating the OWASP Foundation website to not appear so much like a...well, a wiki. That talk was carried forward into 2017 and 2018 and, with each year, the proposal got pushed ahead as there were other, deeper projects to tackle. With the arrival of 2019 and a firm project plan under the guidance of Mike McCamon, Executive Director, we are finally moving toward a functioning, modern website that will be a whole lot less...wiki-like. The journey has been circuitous and, while we are not anywhere near complete, we have a set plan in place to bring it to fruition within the calendar year (second quarter of the year, actually).

TLDR: How Can You Help?

There are certainly ways in which you can get involved now. For instance, we are looking for a clean way to get wiki pages into GitHub markdown format for archival. I have done some work here but there are parsing issues with some of the tools. Do you know a good tool or have you done similar work? Also, are you or do you know a good designer, someone familiar with GitHub pages that can provide some useful help and feedback along the way? A Jekyll expert to help code a theme with a handful of templates would be a great addition. In addition, we could use website server admins who could help with assigning redirects to maintain search integrity. Finally, there will be a great many pages to move that we will also eventually need community involvement in.

So, What Have We Done?

Thus far we have researched various ideas for standing up a new site, including modifying the current wiki, spinning up our own web server, contracting a third party to host and build a new site, and also using existing infrastructure with our own content to launch a new face for OWASP. Our discussions led us to a familiar place, one that nearly every developer in the OWASP space is familiar with: GitHub.

In our conversations with GitHub, it became readily apparent that using the platform would be a win for the Foundation as well as GitHub. Nearly everyone who runs a project at OWASP (documentation or otherwise) uses GitHub. Because our target audience is also mostly developers we know that they are also very comfortable with the platform. And while GitHub has a number of high profile companies using their GitHub Pages, the use of the platform as the basis for the entire website of the number one non-profit foundation in the application security sector is a big draw.

We have run with that GitHub Pages idea and have spent internal manpower on a proof of concept. This proof of concept is less about the UX of the site than the functionality, the ability to utilize the authentication systems, and the ability to utilize automation to push out changes quickly.

Where Are We Now?

We are doing the final stages of website architecture. We are also planning what needs to be in the site, how the pieces will integrate with current projects and chapters, and how we might utilize the community to integrate the pieces so that we have a visually and functionally cohesive website that spans across multiple repositories.

What Is Next?

We will soon be looking for a modern website design that is responsive and clean. We will begin using the knowledge gained from our proof of concept to build out the internals of the website and then we will start implementing the highest traffic pages and administrative areas into the new platform. Once we have the big-ticket items moved we will start looking at what is left and moving over those pieces. The eventual goal would be to have a new, modern website for the future of OWASP while keeping the wiki as an archive of really useful information.

We hope you are as excited as we are about the future of the OWASP Foundation website and will join us as we move toward a modern web presence. If you have any questions or would like to volunteer your time, experience or knowledge, please contact me at harold.blankenship@owasp.com

AzureHunter - A Cloud Forensics Powershell Module To Run Threat Hunting Playbooks On Data From Azure And O365

A Powershell module to run threat hunting playbooks on data from Azure and O365 for Cloud Forensics purposes.

Getting Started

1. Check that you have the right O365 Permissions

The following roles are required in Exchange Online, in order to be able to have read only access to the UnifiedAuditLog: View-Only Audit Logs or Audit Logs.

These roles are assigned by default to the Compliance Management role group in Exchange Admin Center.

NOTE: if you are a security analyst, incident responder or threat hunter and your organization is NOT giving you read-only access to these audit logs, you need to seriously question what their detection and response strategy is!

More information:

NOTE: your admin can verify these requirements by running Get-ManagementRoleEntry "*\Search-UnifiedAuditLog" in your Azure tenancy cloud shell or local powershell instance connected to Azure.

2. Ensure ExchangeOnlineManagement v2 PowerShell Module is installed

Please make sure you have ExchangeOnlineManagement (EXOv2) installed. You can find instructions on the web or go directly to my little KB on how to do it at the soc analyst scrolls

3. Either Clone the Repo or Install AzureHunter from the PSGallery

3.1 Cloning the Repo

Clone this repository
Import the module Import-Module .\source\AzureHunter.psd1

3.2 Install AzureHunter from the PSGallery

All you need to do is:

Install-Module AzureHunter -Scope CurrentUser
Import-Module AzureHunter

What is the UnifiedAuditLog?

The unified audit log contains user, group, application, domain, and directory activities performed in the Microsoft 365 admin center or in the Azure management portal. For a complete list of Azure AD events, see the list of RecordTypes.

The UnifiedAuditLog is a great source of cloud forensic information since it contains a wealth of data on multiple types of cloud operations like ExchangeItems, SharePoint, Azure AD, OneDrive, Data Governance, Data Loss Prevention, Windows Defender Alerts and Quarantine events, Threat intelligence events in Microsoft Defender for Office 365 and the list goes on and on!

AzureHunter Data Consistency Checks

AzureHunter implements some useful logic to ensure that the highest log density is mined and exported from Azure & O365 Audit Logs. In order to do this, we run two different operations for each cycle (batch):

Automatic Window Time Reduction: this check ensures that the time interval is reduced to the optimal interval based on the ResultSizeUpperThreshold parameter which by default is 20k. This means, if the amounts of logs returned within your designated TimeInterval is higher than ResultSizeUpperThreshold, then an automatic adjustment will take place.
Sequential Data Check: are returned Record Indexes sequentially valid?

Usage

Ensure you connect to ExchangeOnline

It's recommended that you run Connect-ExchangeOnline before running any AzureHunter commands. The program checks for an active remote session and attempts to connect but some versions of Powershell don't allow this and you need to do it yourself regardless.

Run AzureHunter

AzureHunter has two main commands: Search-AzureCloudUnifiedLog and Invoke-HuntAzureAuditLogs.

The purpose of Search-AzureCloudUnifiedLog is to implement a complex logic to ensure that the highest percentage of UnifiedAuditLog records are mined from Azure. By default, it will export extracted and deduplicated records to a CSV file.

The purpose of Invoke-HuntAzureAuditLogs is to provide a flexible interface into hunting playbooks stored in the playbooks folder. These playbooks are designed so that anyone can contribute with their own analytics and ideas. So far, only two very simple playbooks have been developed: AzHunter.Playbook.Exporter and AzHunter.Playbook.LogonAnalyser. The Exporter takes care of exporting records after applying de-duplication and sorting operations to the data. The LogonAnalyser is in beta mode and extracts events where the Operations property is UserLoggedIn. It is an example of what can be done with the playbooks and how easy it is to construct one.

When running Search-AzureCloudUnifiedLog, you can pass in a list of playbooks to run per log batch. Search-AzureCloudUnifiedLog will pass on the batch to the playbooks via Invoke-HuntAzureAuditLogs.

Finally Invoke-HuntAzureAuditLogs can, be used standalone. If you have an export of UnifiedAuditLog records, you can load them into a Powershell Array and pass them on to this command and specify the relevant playbooks.

Example 1 | Run search on Azure UnifiedAuditLog and extract records to CSV file (default behaviour)

Search-AzureCloudUnifiedLog -StartDate "2020-03-06T10:00:00" -EndDate "2020-06-09T12:40:00" -TimeInterval 12 -AggregatedResultsFlushSize 5000 -Verbose

This command will:

Search data between the dates in StartDate and EndDate
Implement a window of 12 hours between these dates, which will be used to sweep the entire length of the time interval (StartDate --> EndDate). This window will be automatically reduced and adjusted to provide the maximum amount of records within the window, thus ensuring higher quality of output. The time window slides sequentially until reaching the EndDate.
The AggregatedResultsFlushSize parameter speficies the batches of records that will be processed by downstream playbooks. We are telling AzureHunter here to process the batch of records once the total amount reaches 5000. This way, you can get results on the fly, without having to wait for hours until a huge span of records is exported to CSV files.

Example 2 | Run Hunting Playbooks on CSV File

We assume that you have exported UnifiedAuditLog records to a CSV file, if so you can then do:

$RecordArray = Import-Csv .\my-exported-records.csv
Invoke-HuntAzureAuditLogs -Records $RecordArray -Playbooks 'AzHunter.Playbook.LogonAnalyser'

You can run more than one playbook by separating them via commas, they will run sequentially:

$RecordArray = Import-Csv .\my-exported-records.csv
Invoke-HuntAzureAuditLogs -Records $RecordArray -Playbooks 'AzHunter.Playbook.Exporter', 'AzHunter.Playbook.LogonAnalyser'

Why?

Since the aftermath of the SolarWinds Supply Chain Compromise many tools have emerged out of deep forges of cyberforensicators, carefully developed by cyber blacksmith ninjas. These tools usually help you perform cloud forensics in Azure. My intention with AzureHunter is not to bring more noise to this crowded space, however, I found myself in the need to address some gaps that I have observed in some of the tools in the space (I might be wrong though, since there is a proliferation of tools out there and I don't know them all...):

Azure cloud forensic tools don't usually address the complications of the Powershell API for the UnifiedAuditLog. This API is very unstable and inconsistent when exporting large quantities of data. I wanted to develop an interface that is fault tolerant (enough) to address some of these issues focusing solely on the UnifiedAuditLog since this is the Azure artefact that contains the most relevant and detailed activity logs for users, applications and services.
Azure cloud forensic tools don't usually put focus on developing extensible Playbooks. I wanted to come up with a simple framework that would help the community create and share new playbooks to extract different types of meaning off the same data.

If, however, you are looking for a more feature rich and mature application for Azure Cloud Forensics I would suggest you check out the excellent work performed by the cyber security experts that created the following applications:

CISA's Sparrow
HAWK
CrowdStrike Reporting Tool for Azure CRT

I'm sure there is a more extensive list of tools, but these are the ones I could come up with. Feel free to suggest some more.

Why Powershell?

I didn't want to re-invent the wheel
Yes the Powershell interface to Azure's UnifiedAuditLog is unstable, but in terms of time-to-production it would have taken me an insane amount of hours to achieve the same thing writing a whole new interface in languages such as .NET, Golang or Python to achieve the same objectives. In the meanwhile, the world of Cyber Defense and Response does not wait!

TODO

Specify standard playbook metadata attributes that need to be present so that AzureHunter can leverage them.
Allow for playbooks to specify dependencies on other playbooks so that one needs to be run before the other. Playbook chaining could produce interesting results and avoid code duplication.
Develop Pester tests and Coveralls results.
Develop documentation in ReadTheDocs.
Allow for the specification of playbooks in SIGMA rule standard (this might require some PR to the SIGMA repo)
