Flutter: Cubit For State Management
By: Lifereze Arnold
Tags: Flutter Ui, Flutter Widget, Flutter App Development

Cubit is a subset of BLoc implementation which makes state emission simple. It did away with events implementation.

Primarily, it’s a class that stores an observable state, and the state is “monitored” by streams.

Connecting Cubit to User Interface

Cubit is a backend technology and as such, we need to connect it to the user interface. We use a builder just like a “StreamBuilder” but with cubit, there is a possibility of rescuing it from a widget tree using providers.

At every change of state, we use emit() to update the widget. It’s also possible and advisable to only listen to the changes without building the widget.

Injecting Cubit In a Widget Tree

Cubit utilizes a provider package for dependency injection. When injected through the Material App, will be available throughout the app. Check this!

Sample App

A flutter Cubit App displaying trending movies being fetched from an External API. (irvin5k)

The full code is available on my GitHub

Consuming the API using Cubit

Movies states

An abstract class called MoviesState extending Equatable.

Equatable is a package used to help the Cubit compare States, very useful to distinguish equal states with slightly different content.

There will be states for InitialList, Loading, Loaded Movies, and Error.

Constructing a Cubit:

We need to construct a cubit for API consumption.

Write a function that will emit the movies:

The function will be called directly in the constructor to load the movies at class instantiation.

The function can be called from a different place too.

Connect Cubit to UserInterface:

There will be a widget for every state, so it’s necessary to handle the type of each emitted state.

Conclusion

Cubit has reduced the complexity of using the Bloc package. Its core selling points are simplicity, immutability, and interoperability with BLoC.

Nowadays, Flutter has become the first choice for startups as well as developers. Flutter is a cross-platform mobile app development framework created by Google in the year 2017. According to GitHubs’s 2019 report, Flutter is the fastest-growing mobile app development platform.

Mobile app development in Flutter is very easy than any other programming language. It fastest functionality and easy to build app creating a lot of buzz in the tech world. It allows businesses to develop cross-platform mobile applications in less time within budget. That’s what makes flutter premier for mobile app development.

If you’re a startup business or established and planning to develop a cross-platform mobile app, then the Flutter is an ideal choice for you.

Here is what makes Flutter ideal for mobile app development in 2020.

Save your time

While using flutter’s hot reload feature, there is no need to time waste on deployment like regular programming. You can implement all the changes directly without leaving the current application state. With flutter you no need to compromise on speed and development while fixing bugs, building UI, or adding new features.

Ideal for startup MVPs

If you want to develop your product as soon as possible, Flutter is a good option for you. It’s cheaper to develop a mobile application with Flutter because you don’t need to build and maintain two mobile apps, one for iOS and one for Android. To create your MVP in Flutter all you need one developer only.

Cross-Platform development

Cross-Platform App Development with Flutter is very easy as this technology is compatible with various IDEs such as Android Studio, VS Code, IntelliJ, etc. Developers can use these IDEs of their choice to build mobile apps.

Low Development Cost

Low development cost is also the reason for its popularity among developers or startups. And, it is a great benefit that everyone can take. Using a single codebase, you can build an application for two platforms- iOS and Android respectively.

Faster code Writing

Flutter programming language Dart is easy to learn and get started with. For developers, coding is very easy and fast using this framework. With its widgets and code libraries, developers require less-effort to design and develop an application. It uses JavaScript libraries that also play an important role in building cross-platform applications for Android and iOS.

My first bug on Google

So, I was trying Google this time to see if I get something interseting in it. I spent like 20 days on an acquisition and finally I found some interesting stuffs over there. This is the tell about one of them:)

While I was testing almost everything, I saw a URI in burp which was providing some user data including thier user IDs and usernames. It was looking something like this:- redected.com/c/ask/20/l/latest.json. It got my attention so I started searching for some info where I could try other users’ user IDs or username as well.

Finally I found an endpoint where it was showing the data of my account. The Endpoint looked like this:- redected.com/u/yourusername.json. Well this was the endpoint which I was trying to find since a while and that’s all we need as a hacker! I changed the usernames to the ones which I found from another endpoint and BOOM! I was able to see the PII of other users as well. I have put some POCs of them below:-

That was an easy find once you get that endpoint. I took the time and it paid off. I would like to mention “no target is safe”. What you need to create is this mindset. Once you have it, go ahead and hack’em all! Also, it really matters how much time you are putting into your efforts. Big targets, actually huge targets need time to get exploited. Stick with it and you will find something eventually:)

I hope this helps people out there to observe targets better. With this, I will wrap up this write-up here. If you like this, follow me on twitter. Also, a clap will be highly appreciated:)

Keep your head high and your hacks higher!

Happy hacking! adios ❤

[Task 1]

Basic Nmap scan:

nmap -sS -sV -O -T4 <ip-address> -oN basic_scan.nmap

The scan sheds some light on further fingerprinting paths we can take, and I suggest to run the following scan:

Sudo gobuster dir -u http://ip-addr -w /usr/share/wordlists/dirb/common.txt Nmap --script=vuln ip-addr -oN vuln_scan.nmap Enum4linux -A ip-addr > smb_enum.txt Nmap --script=smb-enum-share.nse ip-addr

Gobuster’s scan output:

The /squirrelmail directs to the web-based mail service. It runs on PHP and built for the IMAP and SMTP services support.

The output from both enum4linux and Nmap’s smb-enum-shares NSE script has some hints regarding the potential user of the mail service.

The user might be milesdyson. But what could be a password?

There’s Anonymous share available, so the following smbclient command will let us in the shared folder:

smbclient //ip-addr/anonymous

Browse through directories and locate a file with passwords. We will use that file as the THC-Hydra input for mail service login brute-forcing.

Intercept the login request with Burp Suite …

… and use the POST form as a template for hydra’s http-form-post password attack.
How to deploy Zero Trust with SDP?

How to deploy Zero Trust with SDP?

Zero Trust Networks with SDP: innovax Technologies, LLC

In traditional network, perimeter defense innately assumes that attacks are often originated from outside and hence, network perimeter worthy of stringent scrutiny. An analogy of perimeter defense is to compare it with medieval era castle with invincible walls, a well-defined entry point across the draw bridge (router), portcullis (firewall) and guards (IDS). Such a design may only protect outside attacks but how about attacks that may occur inside the wall.

Today, many network attacks may origin from inside or in fact in can come from anywhere. The dynamics of attacks today are more sophisticated, no way of knowing where it can originate from and today’s network may blur the line of perimeter making it difficult isolate traffic. Proliferation of new technology such smartphones, mobile-connected wireless devices, social networks, and IOTs are creating increasingly more security vulnerabilities blurring the line between internal and external networks allowing hackers to circumvent detection. For example, increase use of SaaS and virtualization makes fixed perimeter defense inadequate. According to McAfee, 52% of the respondents surveyed for indicated that they tracked a malware infection to a Software-as-a-service (SaaS). Moreover, 6.1 millions DDOS attacks and data breaches are reported in 2017 that occurred due to inadequate access control.

Software defined perimeters (SDP) address these issues by giving application owners the ability to deploy perimeters dynamically while retaining the traditional notion of impregnability and inaccessibility to “outsiders,” with ability to deploy anywhere — internet, cloud, hosting center, private network or across all these locations.

How I CSRF’d My First Bounty!
By: Rajesh Ranjan
Tags: Bugcrowd, Infosec, Csrf, Bug Bounty

Hello Everyone!

This is my first blog post, and I decided to start off by sharing about my recent finding. It was a CSRF issue, which earned me $500!

What makes this even more special for me is that it was my first bounty ever!

Introduction to CSRF:

Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they’re currently authenticated.

Initial Reconnaissance Phase

So, I got an invitation for this private program on Bugcrowd, and it was an e-commerce website.

During my initial recon, I noticed that the users can add their address into their account. So, I quickly checked the request and there was some token named form_key that was being used to protect the users from CSRF attack.

form_key to protect CSRF attacks

So, the next thought which came to my mind was, is there any server side validation on this token?

I quickly logged into my second test account, generated a CSRF PoC, removed the token for this particular request, and sent it to the victim.

And the final request was something like this:

Removed the form_key value in the request

Did you notice something? I have removed the form_key value from the PoC, and not the entire input tag.

I sent this to the victim, and when the victim clicked on “Submit”, the address was added to his account, which was the attacker’s address.

Attacker’s address added to victim account

Boom! Like I suspected, there was no server-side validation on form_key token.

So, the next time you come across a CSRF token, be sure to perform this kind of validation.

Timeline:

Issue reported: 06 Nov 2019

Triaged as P3: 09 Nov 2019

Bounty received: 05 Jan 2020

Thanks for reading. Hope it helps

HOW TO USE LEAKED USER DATABASE?
Tags: Infosec, Security, Thetimeloops, Netflix Craking, Password Analysis

We often hear that “tik tok user database leaked by hacker” PS: i hate tik tok !

A user Database consist of login data . It can have mail , usernames , phone numbers etc .

The data inside a leaked database depend upon the login details used by particular site.

some famous format of leaked database are:

1. MAIL : PASSWORD

2. USERNAME : PASSWORD

user database is also called combo list.

HOW TO USE THIS COMBO LIST?

1. To crack premium accounts yes you read it right!

you can bruteforce this combo list using a checker ( netflix checker , prime video checker etc etc)

Checker will login each data one by one and will save succesfully logged mail and password.

PS: this is the way hackers cracks the premium account

leaked database can be very helpful LOL

ANALYSING THE PASSWORDS AND USING THEM TO HACK ACCOUNTS!

These databases contains large amount of password that public use if we could analyse them and use them for bruteforcing the users logins. WE WOULD DEFINETLY GET A HIT !

But a analysis of database with over billions of password and text is impossible !

if would be like searching for the most common length of hairs by measuring them one by one

But a script can analyse those password in few minutes or hours (*depends on the speed of ur pc*)

Tool name is — PIPAL !

Cookie poisoning leads to DoS and Privacy Violation
By: Benjamin Walter
Tags: Infosec, Technology, Cybersecurity, Hacking, Bug Bounty

When the verification goes wrong.

Avatar cookie contains the URL of the avatar image. But what if we change that?

When I was hunting on cs.money, I noticed that the avatar cookie had the url for the user’s avatar on Steam. I changed the cookie to the URL of some other image and I saw that it was loading on the main page.

Until here there is nothing very special. We can load other images rather than the expected one. So what?

Okay, I tried to chat with support and… my request got blocked. After playing around with the cookie value a little bit, I tried to insert part of the steam avatar url as a parameter for my server.

Privacy Violation

Yes, I was right. The server was not checking the URL properly. The back-end verification was something like this (pseudocode):

The right verification should be:

I got a request on my server from the supporter browser. It tries to load the image url by sending a HTTP request to my server. So now I have access to supporter IP Address and User-Agent.

Denial of Service

Now, think. What if instead of the hacker server, we insert the cs.money logout URL? Bingo!

The supporter browser makes a request to the logout URL and disconnect him.

Final thoughts

It is amazing to see how a small flaw, just a wrong verification o avatar cookie, have a impact like that.

Cs.money paid me a $ 500 reward (high impact at support.cs.money). As I had already reported the problem (able to change avatar to another images) and they closed as Not Applicable, they kindly gave me a $200 bonus. You can check my report here.

Using MacChanger on Linux Tutorial
By: Skynet Tools
Tags: Infosec, Tutorial, Linux, Pentesting, Hacking

What is a mac address?

MAC stands for “Media Access Control”. To summarize is a unique identifier thats embedded onto the ROM of the network interface card. On networks the mac address is whats used for communication(ARP resolves IPs to mac adresses). Figures out what More Info: http://en.wikipedia.org/wiki/MAC_address

How Is A Mac Address Assigned?

Every companies that produces hardware requiring a Mac Address is granted a starting prefix by the IEEE association. So if you want to spoof a specific piece of hardware then you would need to use the correct prefix. The full list can be found (HERE)

Why Is Changing Mac Addresses A Security Risk?

There is a few different ways that mac address spoofing can present risks. One would be to bypass Mac Address filtering that various routers, switches, and firewalls can put in place. If a hacker monitors traffic he can see who is communicating with an access point then then clone their mac address to gain access to the network(once that mac address is off the network). This method can also be used to spoof specific pieces of hardware if for some sort of spear phishing attack was put in place.

Note: You will need to run the following commands as root.

The tool we will be using is “macchanger”. First you will need to install it.

apt-get install macchanger[

or

yum install macchanger

First because we cannot change the mac address on an active card we need to run

ifconfig wlan0 down

You will leave it down until after the mac address as been changed.

To view the list of options for this tool you can run

macchanger –help

To view a list of available commands for this application.

If you are looking to spoof a specific device you can get the prefix for the mac address from the link I provided above or by running the command

macchanger -l

So if you wanted to to spoof say a cisco device you would do

macchanger -m 00:e0:f9:52:72:f6 wlan0

Wlan0 would be the device in which your trying to spoof the mac for.

Then after this you would run

ifconfig wlan0 up

If you are not bothered about specifying your mac address as a specific device you can run

macchanger -a

Which will select a random vendor and spoof it

or

macchanger -r

Which won’t focus on vendors and just randomly set the mac address

When you learn something new alone, you MUST become your own coach first before you become a student!

Because you should motivate yourself. Because you need to be consistent. Because you must set a goal and stay focused to achieve it.

Now, let me give you a quick peek into the world of Penetration Testing.

When you are starting new, firstly:

Decide whether you want to do pentesting to: (1.) Learn or (2.) To Earn.

Learn or To Earn. If you are looking to learn only then the I would highly recommend to exploit vulnerable machines on: Vulnhubs and/or HackTheBox .

and/or . If you are looking to Earn then Bug Crowd and HackerOne is the place for you. Note : This will be the most challenging as you will be competing against several pentesters to find bugs and earn bounty. But, its doable.

and is the place for you. : This will be the most challenging as you will be competing against several pentesters to find bugs and earn bounty. But, its doable. BugCrowd and HackerOne focuses highly on web application pentesting whereas Vulnhubs, HackTheBox is more inclined towards Infrastructure types of testing.

Metasploit Workspaces

Metasploit has workspaces that can be used to keep track of various scans you perform on different hosts and networks. The workspace is stored as a table in the Metasploit database. This allows you to easily manage scans you may perform for various organizations.

Use the command

workspace

to view your current workspace and to ensure you will save the results as well as that you are in the correct workspace.

The initial workspace is named “default”. You can create your own workspace using the following command

workspace -a workspacename

Once you have created a new workspace you can select it as your active workspace by running

Understanding Compliance Audits and What They Mean for Your Business
Tags: Infosec, Compliance, Cybersecurity Awareness, Information Security, Cybersecurity

Whether your organization is large or small, compliance is an important part of running a successful business.

But what exactly does compliance mean and how can you tell if you’re compliant?

A compliance audit is a formal external review of an organization’s operations and procedures to ensure they are following all applicable laws, rules, standards, and regulations. In other words, a compliance audit asks “Is the company doing what it’s supposed to do and what it has agreed to do?”

The audit report identifies any gaps in compliance and makes recommendations for resolving the issues.

Visualizing these processes and operations is one of the best ways to accurately observe and evaluate compliance in a complex system. Visualizing the data helps the auditor identify and understand any disconnects in the process flow so they can make more precise judgments and recommendations.

Compliance is important for maintaining professional standards of business, reassuring partners and clients, and protecting consumers. Noncompliance could lead to significant penalties and sanctions, and damage to your reputation, so regular audits are crucial to ensure everything is in order.
Overwrite Strings in an executable
By: Mark Mo
Tags: Infosec, Blue Team, Red Team

This is a quick and dirty POC with no frills, no guard rails and almost no testing 😊.

It looks for things like “mimikatz” and “sekurlsa” in the executable and replaces it with a string like “mimifish” and “sekufish” but in the executable rather than the source code. Helpful if you don’t have the source code!

All this does is takes an EXE and turns it into a HEX string. It converts the string to search for and string to replace into HEX and then searches for it in the HEX representation of the file. Then replaces the value and converts it back to a file. In this POC, the FIND string size needs to be the same as the REPLACE string size.

This is what normal mimikatz looks like from Benjamin Delpy and Vincent le Toux.

And here is what it looks like after I replace some strings in the executable. Notice it didn’t find “sekurlsa” because I replaced it with “sekufish”. Also I’ve butchered the the ASCII art (I believe I once read that some AV’s look for the ascii art of mimikatz).

And when I run “sekufish” instead of “sekurlsa” it still runs like normal and I’m dumping credentials on my machine. Hooray I didn’t destroy the functionality.

Here is a quick virus total look of the binary before the string replacement.

After here is virus total after the string replacement. It made a difference!

I only spent an hour on changing a few of the strings so it is likely, with some effort, this might fare better in Virus Total. One thing to note, when I ran DITTO on the binary (and cloned notepad) it also dropped the detection rate further.

Here is the POC code for a console program. I hard coded the input and output files (sorry I’m super busy).

Using image scanning to make our environments safer

At YOOX NET-A-PORTER GROUP, we build and deploy thousands (literally!) of containers daily. To keep our Kubernetes environments safe, we strive to follow best practices. However, securing Docker containers is a broad topic.

We follow best practices such as never allowing them to run as root, only using official base images, and reducing the attack surface by avoiding the presence of unneeded packages. On top of that, we implemented image security scanning via AWS ECR.

By default, every image gets scanned when pushed to the repository. Still, unless we force everyone to check the scanning results, we need a way to be sure we do not deploy images with vulnerabilities in our environments.

We don’t like to rely on manual processes and in the SRE team we are big on automating and monitoring everything.

So that’s why we created a small Go application called k8s-radar, which is a simple tool that will, for a given list of images, automatically check and report the vulnerabilities found by our image scanning service. We can then plug-in those results into our monitoring tools, chat or our deployment pipelines. Let’s take a look at what this looks like in practice.

We run k8s-radar daily through our environments and report the results back to Slack, so everyone is aware when a new issue is found.

But, of course, we do not want to wait until the image is running somewhere to report vulnerabilities, so we plugged k8s-radar into our deployment pipelines. If k8s-radar finds a vulnerability in one of the images that are going deployed, the job will fail.

We plan to make the k8s-radar run smoothly in a Kubernetes cluster and support more registries like Quay.io and are looking into the possibility of open-sourcing k8s-radar soon. Stay tuned for more!

4 Things I Love About Being a Mom
By: Susan Urban
Tags: Kids, Parenting, Family, Moms, Baby

4 things I love about being a mom is a private list that I decided to share with you. I am a happy mother of two amazing daughters, and I like to share my joy with others. I hope that this list may help expecting moms get a positive perspective or comfort you — as a mom — on one of those difficult days (that we have too sometimes!).

My baby’s „firsts”

I get so excited with every another „first time”! First kisses, first rolls, then first time walking, first day at preschool… It’s all happening so fast! Parenting is a long road. Try to divide it into pieces and enjoy every step to the most. Don’t forget to take pictures — you will want to get back to those days!

Celebrating successes

I enjoy celebrating every little success together a lot! It is good to make your baby feel special and show that you are proud of them. For example, after finally giving up a pacifier (check out our methods in the How to help your child to give up the pacifier book), we had a little „goodbye party”.

Children’s stuff

One of the things I love about being a mom is a possibility to buy things (and spoil my girls just a little bit). Stuff for kids is so cute these days! Clothes, toys, room decor… You can pick the most beautiful things in the world and give them to the person you love the most. How cool is that?

And children books? Amazing!

Sense of security

Being a ‚safe spot’ for someone is one incredible, indescribable feeling! Little baby falling asleep in your arms, ability to calm with just your presence and touch… On the other hand, this responsibility may be scary and overwhelming but don’t think about it too much.

All those things I love about being a mom are in fact a part of one, most crucial matter: watching your child grow by your side. Try to live it to the fullest!

What Do You Really Know About Baby Boomers?
By: Mike Schoultz
Tags: Baby Boomers, Baby, Knowledge

Does your business have products or services of interest to customers classified in the baby boomer segment? If so, you should know more about these baby boomer facts.

Consider these facts about the baby boomer customer segment:

One USA boomer is turning 65 every 8 seconds — that rate will continue for the next 15 years.

The USA adult population has grown by 23 million in the 10 years between 2006 and 2016.

Ages 18–49 will have grown by 1 million — age 50+ will have grown by 22 million.

At age 50, we effectively have … a full 50% of our healthy adult life ahead of us.

An average American will buy 13 cars in the course of a lifetime — 7 after age 50.

Age 55-plusers are … more active in online finance, shopping, and entertainment than those under 55.

Boomers inherit $8.4 trillion in the next few years; 70% of boomers will inherit on average $300K.

The net wealth of households headed by 65+ is 47 times greater than the net wealth of households headed by someone ❤5; 20 years ago the ratio was 10:1.

Have you added this target segment to your business strategy yet?

Tags: Jenkins, Api Testing, Continuous Integration, Test Automation, Karate

Whatever project we are working on, over a period of time we end up having a large suite of tests that need to be run very often. To have tests running regularly, it is key that we integrate test suite execution with our Continuous Integration tool chain.

If you are new to API testing with karate you can go through my previous post-Kick-off web services testing with Karate. That will be sufficient to get you started with karate.

In this post, I will walk you through karate -Jenkins integration in few easy steps.

I. Install Maven in Jenkins

Go to Jenkins Dashboard ->Manage Jenkins ->Manage plugins ->Available ->Maven Integration plugin ->Install

2. Go to Jenkins Dashboard -> New Item -> Maven Project option will be available

II. Create a Maven project

Go to Jenkins Dashboard -> New Item -> Choose name for the Maven Project (e.g. KarateMavenExample)

III. Configure Maven project

In Configure Page, do the following changes

1. Discard Old builds

-Days to keep builds: 7

-Max no. of builds to keep: 15

2. Build -> advanced -> enable the following

-Resolve Dependencies during Pom parsing

-Use custom workspace (add path of the folder containing pom.xml)

-Goals & Options = Clean test

If you have different environments configured in karate-config.js, you can use the “Goals & Options” to choose the environment you want to run in.

e.g : test -DargLine="-Dkarate.env=UAT"

3. Apply & Save

IV. Go to Project Window and Click ‘Build Now’.

Go to ‘Console Output’ and now you can see the test results.

Cypress tips #2 — Testing email flows with Mailosaur
By: Filip Hric
Tags: Cypress, Software Testing, Test Automation, Testing, End To End Testing

„The more tests resemble the way your software is used, the more confidence they can give you” — Kent C. Dodds

In this second Cypress tip I would like to give you a glimpse of how we use Cypress with a tool called Mailosaur.

Telling the whole story

When writing tests, I like to resemble user behavior as much as possible. In other words, I want to tell the whole story.

Let me give you an example. Let’s say you forgot your password to your Slido account. Here is what you would do as a user. You would:

go to reset login page and request password reset receive an email with a reset link visit that link type in your new password log in with new password

With Cypress, you can easily take care of step 1. But getting to step 3 requires opening an email inbox, which is not something you can easily do (or want to do) in a test.

Normally, this is something you would solve on staging environment, by either creating a special setup, where you can access the information you need. But that is something that user does not do, so it does not resemble the user. You can of course make sure that every part of the functionality works (which is good), but if you are like me, you’ll feel like that’s not enough.

Enter Mailosaur

Mailosaur a service that creates an email inbox for you. What’s special about it is, that you can access it not only via their interface, but also via their API. All of email content and metadata can be viewed in plain text, HTML, or parsed to JSON, where you can view all links, attachments or images.

My favourite part is the ability to wait for a specific message to arrive. This means you can access all of that information within few milliseconds and then use them further in your test.

With Mailosaur, you create an email server, where all emails with specific username land. You’ll end up with something like:

{{any string here}}.abcdefg@mailosaur.io

Integrating Mailosaur with Cypress

Since you can get all of the information you need just by calling a simple http request, you can do exactly that — by using Cypress cy.request() command. You can then make assertions on returned response, or use that data for further test execution.

example test with mailosaur

After obtaining the reset password link, you can continue with your test journey. Opening link, setting up new password, and then finally logging in to application. This resembles real life behavior more closely, connecting and integrating each step.

If you liked this article, you’re going to love my new course on Cypress.io. It’s called test automation for people in a hurry, and it is exactly what you’d expect. A compact, fast and straight-to-the-point course with lots of practical examples and challenges. Click on this link to check it out!
