The chef is a tool used for configuration management and is closely competing with the puppet. So lets us start our discussion with, Why Chef? The software keeps on updating over time. So to utilize the various new features of any software, we need to update the software version. And doing is a simple task if it is on one system.
But if it a case of updating on multiple systems say in any organization it becomes tedious and time-consuming. So to get rid of these repeated things, we need a tool like a chef to automate the configuration management. What is chef? Infrastructure as a code refers to managing the infrastructure by writing the code rather than the manual process.
Some people refer to this as a programmable Infrastructure. It uses pure Ruby, a domain-specific language for writing the system configurations. DevOps Chef is capable of spinning hundreds of instances in less than a minute.
It enables programmers and system administrators to work together instead of waiting for the developers to write the code and for the ops team to deploy them. This configuration management tool serves the process of both developments as well as the ops team. Chef translates the system administration tasks to reusable definitions known as cookbooks and recipes.
In these recipes, the authors can define the system’s desired state by writing the code configuration. Then chef process that code along with data about the specific node where the code is running and ensures that the desired state matches the nature of the system. Are you looking to acquire practical knowledge on the chef, then visits chef online training Irrespective of the infrastructure size, the chef can perform the following automation: Infrastructure configuration Application deployment Configurations across the network Like a puppet, the chef uses a client-server architecture.
Besides, it also contains an extra component called a workstation. Through Chef we can easily configure the pull as well as the push configuration. Pull Configuration: In these types of configuration management, the nodes poll a centralized server periodically for updates. Since the nodes were dynamically configured, pulling will be happening from the centralized server. Pull Configuration: In this type of configuration management, the centralized server pushes all configurations to the nodes.
Here the centralized server uses some commands to configure the nodes. Chef Architecture: The Chef architecture has divided into 3 components: Work Station: The workstation is the simplest term in the admin system. This work station makes the possible interaction with chef-server as well as the chef-nodes.
It is the place where all the cookbooks were created as well as tested. At workstation Cookbook deployments take place. And we can utilize this work station to download the cookbooks created by the other users. While interacting with the chef, we also need to understand the following terms: Development Kit: It contains all the packages that are required to use chef. Chef- Repo: It is a directory of the workstation, where all the cookbooks were present and maintained Knife: This command enables the work station to communicate the content of its repo-directory Test Kitchen: It provides the development environment to the work station which enables to create and test workbooks before they are distributed.
Chef Server: It is the center of work stations and nodes. This contains all the cookbooks, recipes as well as metadata. The workstations send a cookbook to the server using the knife. And the nodes communicate with the server using the chef-client. If any changes are made to the infrastructure as a code, then they must be passed to the chef server to apply to all the nodes.
Nodes: These refer to the machines that are managed or configured by the chef-server which may be virtual servers or the network devices or any other storage devices. Chef client makes the node to stay up to date and runs individually to configure them What are the silent features of chef?
The following were the silent features of Chef: We can manage a large number of servers with fewer employees It allows continuity in the deployment process from building to the testing until the end. Chef can be managed using different operating systems like Linux, Windows It can be integrated with several major cloud service providers. It also helps in managing risk at all stages of deployment.
What are the advantages of Chef? Utilization of the chef has the following advantages: Accelerating Software delivery: When your infrastructure is automated with all the software requirements like creation and testing of new environments, software deployments becomes faster.
Increased Service Resiliency: With the automated infrastructure, we can monitor for bugs as well as errors before they occur. Besides, it can also recover the errors more quickly Risk Management: It lowers the risk and improves compliance at all stages. Moreover, it reduces the conflicts during the development as well as the production environment Cloud Adoption: chef can be easily adapted to the cloud environment.
Here the servers, as well as the infrastructure, can be easily configured, installed, and managed by the chef. And it is capable of running all the cloud and on-premise platforms including servers. Streamlined IT Operation as well as the workflow: It provides a pipeline for continuous deployment from building to the testing.
What are the disadvantages of chef? Utilization of the chef has the following advantages as follows: Learning chef requires the steep learning curve The initial set up is quite complicated It lacks push, so it does not have immediate action on change. And the changes will affect as per the schedule.
Final Words: Everything in this world has some drawbacks, so keep the cons aside and make use of chef advantages for the efficient running of your project. By reaching the end of this blog, I hope you people have gained some stuff regarding chefs regarding the need utilization in the IT industry. You people can get practical knowledge on chef configuration management at Chef Online Course.
Application development has become more common in today’s world. This is because today people can easily develop applications using different frameworks. A framework is essential for the smooth running of the application. It makes the application development simpler and faster. There are many frameworks like Dot Net for the smooth running of the applications.
Even though there are multiple frameworks like Dot Net for developing intuitive applications, the importance of this framework has not yet decreased in the market. Read the complete article to know the details What is Dot Net?
Dot Net framework is a Microsoft software development framework. This framework is responsible for creating applications that run on the Windows platform. The initial version of this framework is released in This framework suits best for form-based as well as web-based applications. This framework supports various languages like Visual Basic and C.
Hence the developers can choose and select the language to develop the application. Dot Net is central to Microsoft’s over-arching development strategy. It is so central to the development of the windows platform. This framework contains a large number of class libraries known as the Framework class library. This programming model provides comprehensive software infrastructure and various services that are necessary to build up robust applications for PC as well as mobile devices.
Get more features of. Net: ASP. Net is a part of the Microsoft. Net platform. These applications are the compiled codes written using the extensible as well as reusable components present in the Dot Net framework.
Net is responsible to produce interactive, data-driven applications over the internet. It contains a large number of controls such as text boxes, buttons, and labels for assembling, configuring, and manipulating the code to create HTML pages. This ASP. Net consists of two models. They are: a Web Forms Model: This model extends the event-driven model of interaction to web applications.
Here the browser submits the web form to the web server and the server returns the full mark up page or the HTML page in response. Here all the client-side user activities are forwarded to the server for stateful processing. The server processes the output of client actions and triggers the reactions. Net framework helps in storing the information regardless of the application state. It consists of page state and session state.
The page state is defined as the state of the client. The session state is defined as the collective information that is obtained from various pages the user visited and worked with the overall session state. Net Model provides various building blocks of ASP. Net pages. It is an object-oriented model that describes the serverside counterparts of all the HTML elements or tags.
Server Controls that help in developing complex user-interface. The Dot Net framework is made up of object-oriented hierarchy.
Usually, an ASP. Net web application is a combination of multiple web pages. When the user requests an ASP. Net system. The ASP. Net runtime transforms the aspx page into the instance of the class that inherits from the base class of the Dot Net framework Dot Net Framework Components: This framework is responsible for various services like memory management, networking, type safety.
This dot net framework mainly consists of 4 components: a Common Language Runtime CLR : It is a program execution engine that loads and executes the program. It is responsible for converting the program into the native code.
Besides, It acts as an interface between framework as well as operating systems. It does various activities like exception handling, memory management, and garbage collection.
Besides, it provides type safety, interoperability, and portability. It is a set of managed libraries that simplify the common application task such as reading or writing the file systems 2 ASP. Net: It is a web framework designed as well as developed by Microsoft. It is responsible for developing websites, web applications as well as web services. With this Query language, user can query for data sources with C or the visual basic programming languages. It combines the simplicity as well as the readability of LINQ and provides the power of parallel computing.
Moreover, it is capable of improving and provides the fast speed to execute the LINQ query by using all available computer capabilities. A Dot Net Developer is responsible for designing, tailoring, and developing software applications according to the business needs. In addition to the determination and analysis of prerequisites for the software, he is also responsible for support as well as continuous development. These are the basic responsibilities of the Dot Net Developer.
And it may vary from company to company. In some cases, the role of the dot net developer may also vary from project to project. This is the basic overview of the Dot Net platform. I hope you people have got an overview of.
Net and its component. Moreover, you people can get hands-on experience on the. Net framework by live industry experts with live use cases at Dot Net Online Course. In the upcoming post of this blog, I’ll be sharing with you the details of the Dot Net components elaborately. Meanwhile, have a glance at out Dot Net interview questions and get placed in your dream firm. Some of them were the green screen, terminals, command-line interface, and the graphical user interfaces.
Besides, there are some more other methods like application program interface API calls, and web-based management calls. Among those, the command line interface is capable of performing repetitive tasks quickly and accurately when managing a large number of the system.
Hence, Microsoft has introduced shell scripting to meet the needs of the user and ensure that each task is done in the same manner. This article gives you a brief explanation of power shell regarding the need and application in real-time in the IT industry.
What is a Power shell? Power shell is a Microsoft scripting and automation platform. It is both a scripting language and a command-line interface.
This platform is built on the. Net framework. This Microsoft platform uses a small program called cmdlets.
This platform is responsible for the configuration, administration, and management of heterogeneous environments in both standalone and networked topologies by utilizing the standard remoting protocols.
Once you start working with a power shell, it provides a set of opportunities for simplifying the tasks and saving time. It does this, using a command-line shell and an associated scripting language. At the time of release, this powerful tool essentially replaces the command prompt to automate the batch process and create the customized system management tools. Do you want to expertise on this tool? Powershell is a popular tool for many MSP because its scalability helps in simplifying the management task and generate insights into devices across the medium or large scale devices.
For instance, you can use cmdlets like the Get command to search for other cmdlets. Besides commands like cmd-help responsible for discovering the syntax of the cmdlet, and uses the invoke-command to run the script locally, remotely or even in a batch control Provide Net wide around Powershell enables you to get around software or program limitation especially on a business-wide scale. For example, PowerShell is responsible for reconfiguring the default setting of a program across the entire network This might be useful if the business wants to roll a specific protocol to all its users using two-factor authentication 2FA or change their passwords for every months.
Scale your efforts across devices: Powershell can be a lifesaver if you want to run scripts across multiple computers, especially if some of them were remote devices. Moreover, this PowerShell is responsible to gather information across multiple devices at once and allows you to install updates, configure settings, gather the information that saves you hours of work and travel time Gain Visibility into information: The advantage of this platform is the accessibility of the computer file system.
Powershell makes it hard to find data in files and the windows registry. Moreover, digital certificates are visible whether it is housed on one computer or many. And it allows you to export the data for reporting purposes.
What you can do with the power shell? With the utilization of power shellcode, companies can roll out the changes and updates and can test the GUI. Besides, it is tightly integrated with most of the Microsoft products. In some cases, products like Microsoft server and office things cannot be done with GUI and only the power shell can do.
Microsoft people have designed this tool as an open-source and cross-platform. And it incorporated its capabilities into several interfaces. This power shell has become a robust solution to automate a range of tedious or administrative tasks and then find the filter and export the information about the computer on a network. It does this by combining the commands called cmdlets and create scripts.
Within the power shell, you can leverage the improved power shell access and control over the windows management instrumentation and the component object model to fine-tune the administrative management. This automation tool is greatly helpful for executing a typical management task.
Besides, this power shell includes adding and deleting accounts, editing groups, and creating a list to view specific types of users or groups. Besides, this powerful tool has an integrated scripting environment ISE , a graphic user interface that lets you run commands and create or test scripts. This interface lets you develop the scripts such as command collection, where you can add the logic for execution. This is particularly useful for system administrators who need to run the command sequences for system configuration.
Likewise, there are multiple uses of power shell in the real-time industry. By reaching the end of this article, I hope you people have gained the best knowledge on power shell. You people can get more practical knowledge on PowerShell taught by real-time experts at power shell online Course. In the upcoming articles of this blog, I’ll be sharing the details of more information on PowerShell.
Define what is Active Directory? Answer: Active Directory is a Meta Data. Active Directory is a data base which store a data base like your user information, computer information and also other network object info. It has capabilities to manage and administrate the complete Network which connect with AD. Answer: Domain local groups assign access permissions to global domain groups for local domain resources. Universal groups grant access to resources in all trusted domains.
I am trying to create a new universal user group. Answer: Universal groups are allowed only in native-mode Windows Server environments.
Native mode requires that all domain controllers be promoted to Windows Server Active Directory. What is an IP address? Answer: Every device connected to the public Internet is assigned a unique number known as an Internet Protocol IP address.
IP addresses consist of four numbers separated by periods also called a ‘dotted-quad’ and look something like In computer networking, an Internet Protocol IP address consists of a numerical identification logical address that network management assigns to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes. The role of the IP address has been characterized as follows: “A name indicates what we seek.
An address indicates where it is. A route indicates how to get there. What is subnet Mask? Answer: A subnet short for “subnetwork” is an identifiably separate part of an organization’s network. Typically, a subnet may represent all the machines at one geographic location, in one building, or on the same local area network LAN.
Having an organization’s network divided into subnets allows it to be connected to the Internet with a single shared network address. Without subnets, an organization could get multiple connections to the Internet, one for each of its physically separate subnetworks, but this would require an unnecessary use of the limited number of network numbers the Internet has to assign.
It would also require that Internet routing tables on gateways outside the organization would need to know about and have to manage routing that could and should be handled within an organization. What is ARP? In an Ethernet local area network, however, addresses for attached devices are 48 bits long. ARP provides the protocol rules for making this correlation and providing address conversion in both directions.
How ARP Works? Answer: When an incoming packet destined for a host machine on a particular local area network arrives at a gateway , the gateway asks the ARP program to find a physical host or MAC address that matches the IP address. The ARP program looks in the ARP cache and, if it finds the address, provides it so that the packet can be converted to the right packet length and format and sent to the machine.
If no entry is found for the IP address, ARP broadcasts a request packet in a special format to all the machines on the LAN to see if one machine knows that it has that IP address associated with it. A machine that recognizes the IP address as its own returns a reply so indicating. Define what is Active Directory Domain Services? Define what is domain? The user need only to log in to the domain to gain access to the resources, which may be located on a number of different servers in the network.
Define what is domain controller? Answer: A Domain controller DC is a server that responds to security authentication requests logging in, checking permissions, etc. A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.
What is a default gateway? What happens if I don’t have one? Answer: a gateway is a routing device that knows how to pass traffic between different subnets and networks. A computer will know some routes a route is the address of each node a packet must go through on the Internet to reach a specific destination , but not the routes to every address on the Internet.
It won’t even know all the routes on the nearest subnets. A gateway will not have this information either, but will at least know the addresses of other gateways it can hand the traffic off to. Your default gateway is on the same subnet as your computer, and is the gateway your computer relies on when it doesn’t know how to route traffic. The default gateway is typically very similar to your IP address, in that many of the numbers may be the same.
However, the default gateway is not your IP address. To see what default gateway you are using, follow the steps below for your operating system. What is a subnet? Answer: In computer networks based on the Internet Protocol Suite, a subnetwork, or subnet, is a portion of the network’s computers and network devices that have a common, designated IP address routing prefix cf.
A routing prefix is the sequence of leading bits of an IP address that precede the portion of the address used as host identifier or rest field in early Internet terminology.
What is an RFC? Name a few if possible not necessarily the numbers, just the ideas behind them What is RFC ? Efforts are in progress within the community to find long term solutions to both of these problems. Meanwhile it is necessary to revisit address allocation procedures, and their impact on the Internet routing system. What is CIDR? For example: CIDR addresses reduce the size of routing tables and make more IP addresses available within organizations.
CIDR is also called supernetting. You have the following Network ID: What is the IP range for your network? Answer: You need at least hosts per network. How many networks can you create?
What subnet mask will you use? You need to view at network traffic. What will you use? Name a few tools? Answer: Monitoring network traffic tool Q. How do I know the path that a packet takes to the destination? Answer: use “tracert” command-line Q. What does the ping Answer: The ping command will send roundtrip packets to a destination other PC, router, printer, etc. The When you have checked Use Text Lookup option, you will see a list of the target objects for the involved lookup field.

To run net group, open a command prompt, type net group with the appropriate parameters, and then press ENTER. Now storm-control kicks in when a port sends 6kpps of broadcast 0. Please note that in case you use -S on edge’s command line, all connections will be made through the supernode – also those to locally neighboring peers.
Utilize Run. We update the online documentation with the latest point release information. Checking a multicast UDP stream. You can check WiFi network connection status from command line using the following command. The Cisco IOS command ip multicast ttl-threshold looks like it might help, but it forces all multicast traffic leaving the interface to be routed via the mcache.
Start studying Chapter 1 Deploying Windows Server. The source – Alternatively, the command line tool VBoxManage can be used. Receiver example. The app will open a command prompt and will probably sit there doing nothing for a while. This protocol is automatically used if DNS is unavailable in Windows e three misconfigured hosts listening to the same multicast group elsewhere at the UW-Madison responded with echo-reply or timestamp reply packets to the ICMP requests to the multicast group f the nmap probe from the laptop included a few tcp syn and ack packets to the multicast group; the firewall logged blocking themWindows 10 Join Multicast Group Command Line The router then forwards data packets addressed to a multicast group G to only those interfaces on which explicit joins have been received.
Step 1: Run Command Prompt as administrator. In the Advanced Options dialog, click Command Prompt. A-Yes they co-exist on the same network. Working mechanism of IGMP multicast group management protocol.
On the computer. Right-click the result and then select Run as administrator. The netdom command or the Powershell Command lets add-computer and remove-computer. In most cases, this protocol is required to access shared folders hosted on legacy systems, such as no longer supported Windows XP, Windows Server and older OSs.
You can also combine the ip igmp command with other IGMP-related commands,. It appears that on bit versions of Windows 10 Home that typing in gpedit. IP multicast routing enables a host source to send packets to a group of hosts receivers anywhere within the IP network by using a special form of IP address called the IP multicast group address.
From the Intune portal, click on Client Apps in the menu down the left hand side. Gather multicast IP addresses info. MDHCP dynamically assigns these available class D addresses to clients who want to temporarily join a multicast group in order to receive a multicast transmission. Using Windows Command Prompt. Here we will use UDP Multicast. Hardening workstations is an important part of reducing this risk.
Type cmd and press Enter. The above steps will open a command prompt wvith elevated privileges. But what if I had needed to brute force it?
The program was not friendly to taking input from stdin, or from running inside python. So I downloaded the source code, installed the FreeBasic compiler, and started hacking at the source until it ran in a way that I could brute force test passwords in 5 seconds.
It would have been possible to get through the initial enumeration of Ethereal with just Burp Repeater and tcpdump, or using responder to read the DNS requests. But writing a shell is much more fun and good coding practice. Another one of the first boxes on HTB, and another simple beginner Windows target.
I can upload a webshell, and use it to get execution and then a shell on the machine. There was a box from HackTheBox. Zipper was a pretty straight-forward box, especially compared to some of the more recent 40 point boxes. The main challenge involved using the API for a product called Zabbix, used to manage and inventory computers in an environment.
I had an opportunity to check out Wizard Labs recently. The box called Dummy recently retired from their system, so I can safely give it a walk-through. Seems popular to start a service with a Windows SMB vulnerability. This was a Windows 7 box, vulnerable to MS The top of the list was legacy, a box that seems like it was one of the first released on HTB.
I thought Giddy was a ton of fun. It was a relateively straight forward box, but I learned two really neat things working it each of which inspired other posts. The box starts with some enumeration that leads to a site that gives inventory.
A local privilege escalation exploit against a vulnerability in the snapd server on Ubuntu was released today by Shenanigans Labs under the name Dirty Sock. The entire thing was about protocols that operate on any environment. There I find an SSH key that gets me a user shell.
Dab had some really neat elements, with a few trolls thrown in. After cracking twelve of them, one gives me ssh access to the box. That beautiful feeling of shell on a box is such a high. But once you realize that you need to pivot through that host deeper into the network, it can take you a bit out of your comfort zone.
Reddish is one of my favorite boxes on HTB. Reddish was initially released as a medium difficulty 30 point box, and after the initial user blood took 9. Later, it was upped again to insane SecNotes is a bit different to write about, since I built it. The goal was to make an easy Windows box that, though the HTB team decided to release it as a medium Windows box.
It was the first box I ever submitted to HackTheBox, and overall, it was a great experience. Either way, after gaining SMB credentials, it allowed the attacker to upload a webshell, and get a shell on the host. Privesc involved diving into the Linux Subsystem for Windows, finding the history file, and getting the admin creds from there.
The Sans Holiday Hack is one of the events I most look forward to each year. This conference even has a bunch of talks , some quite useful for completing the challenge, but others that as just interesting as on their own. If can get a Windows machine to engage my machine with one of these requests, I can perform an offline cracking to attempt to retrieve their password.
In some cases, I could also do a relay attack to authenticate directly to some other server in the network.
Oz was long. There was a bunch of enumeration at the front, but once you get going, it presented a relatively straight forward yet technically interesting path through two websites, a Server-Side Template Injection, using a database to access an SSH key, and then using the key to get access to the main host. The first is another method to get around the fact the su was blocked on the host using PolicyKit with the root password. The second was to take advantage of a kernel bug that was publicly released in November, well after Mischief went live.
From there, I can use those creds to log in and get more creds. The other creds work on a website hosted only on IPv6. That site has command injection, which gives me code execution, a shell as www-data, and creds for loki.
Hackvent is a great CTF, where a different challenge is presented each day, and the techniques necessary to solve each challenge vary widely. Like Advent of Code, I only made it through the first half before a combination of increased difficulty, travel for the holidays, and Holiday Hack and, of course, winning NetWars TOC all led to my stopping Hackvent mid-way.
Still, even the first 12 challenges has some neat stuff, and were interesting enough to write up. And if you want to become a full on jq wizard, all the better. Advent of Code is a fun CTF because it forces you to program, and to think about data structures and efficiency. It starts off easy enough, and gets really hard by the end.
After the first 20 people solve and the leaderboard is full, people start to post answers on reddit on other places, and you can see how others solved it, or help yourself when you get stuck. Active was an example of an easy box that still provided a lot of opportunity to learn. The box was centered around common vulnerabilities associated with Active Directory.
Adding it to the original post. Beyond the enumeration I show here, it will also help enumerate shares that are readable, and can ever execute commands on writable shares. Hawk was a pretty easy box, that provided the challenge to decrypt a file with openssl, then use those credentials to get admin access to a Drupal website. Credential reuse by the daniel user allows me to escalate to that user. It starts with an instance of shenfeng tiny-web-server running on port There was so much to write about for Smasher, it seemed that the buffer overflow in tiny deserved its own post.
In fact, it was rooted in just over 6 minutes! I wanted to take a minute and look under the hood of the phishing documents I generated to gain access to Reel in HTB, to understand what they are doing. Reel was an awesome box because it presents challenges rarely seen in CTF environments, phishing and Active Directory. Most people are aware of the. But did you know that the PowerShell equivalent is enabled by default starting in PowerShell v5 on Windows 10?
This means this file will become more present over time as systems upgrade. Dropzone was unique in many ways.
Right off the bat, an initial nmap scan shows no TCP ports open. Initial shell provides access as an unprivileged user on a relatively unpatched host, vulnerable to several kernel exploits, as well as a token privilege attack. First, the issue of a bash if statement, and how it evaluates on exit status. Next, how Linux handles permissions and ownership between hosts and in and out of archives. TartarSauce was a box with lots of steps, and an interesting focus around two themes: trolling us, and the tar binary.
Moving files to and from a compromised Linux machine is, in general, pretty easy. Windows, is another issue all together. This may be less realistic in an environment where you have to connect from a victim machine back to your attacker box over the public internet where SMB could be blocked , but for environments like PWK labs and HTB where you are vpned into the same LAN as your targets, it works great.
Sunday is definitely one of the easier boxes on HackTheBox. It had a lot of fun concepts, but on a crowded server, they step on each other. We start by using finger to brute-force enumerate users, though once once person logs in, the answer is given to anyone working that host. Olympus was, for the most part, a really fun box, where we got to bounce around between different containers, and a clear path of challenges was presented to us.
The creator did a great job of getting interesting challenges such as dns and wifi cracking into a HTB format. Canape is one of my favorite boxes on HTB. There is a flask website with a pickle deserialization bug. I find that bug by taking advantage of an exposed git repo on the site. I went down several rabbit holes trying to get code execution through couchdb, succeeding with EMPD, succeeding with one config change as root for CVE, and failing with CVE Someone on an InfoSec group I participate in asked for help looking at a potentially malicious word doc.
I took a quick look, and when I sent back the command line that came out, he asked if I could share how I was able to de-obfuscate quickly. The file makes no effort at showing any real cover, and could even be a test upload from the malicious actor. The file writes a vbs script which downloads the next stage, and then runs the script and then the resulting binary. The stage two is still up, so I got a copy, which I was able to identify as nanocore, and do some basic dynamic analysis of that as well.
Poison was one of the first boxes I attempted on HTB. The discovery of a relatively obvious local file include vulnerability drives us towards a web shell via log poisoning. From there, we can find a users password out in the clear, albeit lightly obfuscated, and use that to get ssh access. With our ssh access, we find VNC listening as root on localhost, and. Stratosphere is a super fun box, with an Apache Struts vulnerability that we can exploit to get single command execution, but not a legit full shell.
However, we actually have to exploit the script, to get a root shell. I was aiming for an easy 20 pt Windows box, but it released as a medium 30 pt box. First blood for user just fell, 1 hour and 9 minutes in. Still waiting on root. I hope people enjoy, and if you do the box, please reach out to me on the forums or direct message and let me know what you thought of it, and how you solved it.
Celestial is a fairly easy box that gives us a chance to play with deserialization vulnerabilities in Node. On first finding this sample, I was excited to think that I had found something interesting, rarely detected, and definitely malicious so close to when it was potentially used in a phishing attack.
The more analysis I did, the more it became clear this was more likely a testing document, used by a security team evaluating their employees or an endpoint product.
Still, it was an interesting sample to play with, and understand how it does interesting things like C2 protocol detection and Sandbox detection. This seems to be effective, given the VT dection ratio. In fact, I came across this sample in conversation with someone who worked for one of the few products that was catching this sample. Unfortunately, since the DNS record is no longer present.
I had been on the lookout for PDFs that try to run code to play with, so this seemed like a good place to dive in. After the struggle of getting the tools installed and learning the ins and outs of using them, we can take advantage of this database to upload a webshell to the box. Then with the webshell, we can get a powershell shell access as a low-priv user.
While brute forcing the domains only results in some potentially financial key words, the stage 2 domain acts as a pivot to find an original phish email in VT, which shows this was quite targeted after all. Valentine was one of the first hosts I solved on hack the box. The box is very much on the easier side for HTB.
The class is one of the newer SANS offerings, and so I suspect it will be changing and updating rapidly. Aragog provided a chance to play with XML External Entity XXE vulnerabilities, as well as a chance to modify a running website to capture user credentials.
Nibbles is one of the easier boxes on HTB. It hosts a vulnerable instance of nibbleblog. The privesc involves abusing sudo on a file that is world-writable. Falafel is one of the best put together boxes on HTB. And there are hints distributed to us along the way.
Chatterbox is one of the easier rated boxes on HTB. Overall, this box was both easy and frustrating, as there was really only one exploit to get all the way to system, but yet there were many annoyances along the way. I came across a situation on a htb box today where I needed IE to get a really slow, older, OWA page to fully function and do what I needed to do.
I had a Windows vm around, but it was relatively isolated, and no able to talk directly to my kali vm. SSH tunneling turned out to be the easiest solution here, and since I get questions about SSH tunneling all the time, I figured it would be good to write up a short description.
In my analysis of an emotet sample , I came across PSDecode , and, after some back and forth with the author and a couple updates, got it working on this sample. The tool is very cool. What follows is analysis of a different emotet phishing document similar to the other one I was looking at, as well as PSDecode output for the previous sample. This is one of my favorite boxes on HTB.
We can RE that mod to get root on the system. Probably my least favorite box on HTB, largely because it involved a lot of guessing. I did enjoy looking for privesc without having a shell on the host.
