Smart Ways to Add Value to Your Home

home security

If selling your home either now or in the future is in your mind, you might be considering doing some updates to add value to it. If the structure of your home is on point, you only need to add a few updates. Some of them are simple and cheap, while others are complex and a bit pricey. The best thing is that they will pay in the end. Here are some smart ways you can add value to your home to attract top-dollar buyers.

Make It Energy Efficient

Making your home energy efficient cuts down energy costs, even when you haven't sold it yet. Look for energy consumption audits from energy companies to know what you need to adjust and start saving money. When the time for selling your homes comes, this will be a selling point. Some ways you can increase the efficiency include:

  • Putting energy-efficient windows and doors
  • Replacing incandescent lights with more energy-efficient ones like LED
  • Insulating and sealing leakages
  • Installing energy-efficient toilets and shower heads
  • Installing solar systems

Increase Its Curb Appeal

The curb appeal of a home's exterior will make a potential buyer fall in love with it even without setting their feet on the inside. The exterior of a home creates negative or positive impressions of a place since it's the first-place people set their eyes on. That's why you need to make it near perfect, if not perfect. Have no idea how to do this? Here's how. Mow the lawn.

Prune those shrubs whose branches look out of place. Grow flowers and other plants, and ensure they are always weeded and watered. Even if the space is limited, look for creative ways of making the most out of it. Painting the exterior will also go a long way. If your mailbox is rusty and looks like it'll fall down the next minute, replace it too.

Install A Security System

With the increase in popularity of home security systems, several buyers now want homes where the systems are in place already. The same way someone might look for a house with a swimming pool, or an open plan kitchen, some usually look whether it has a security system. When an appraiser comes into your home, they usually write down its features and compare them with recently sold homes to determine its value.

With a security system in place, they will definitely give it a higher value. Additionally, it will also be beneficial to you even before you sell the house by protecting your valuables from burglary. There are arrays of security systems that will increase your home's marketability, which you can view here.

Light It Up

Another effective way of increasing the value of your home is by lighting it up. Focus on both exterior and interior lighting. Apart from offering functionality, lighting should also make a space appealing. How can you achieve this? Install lighting to highlight features like pathways, water features, and fencing. For the interior space, you can use hanging pendants, spotlights, and other fixtures that increase a room's ambiance.

Make Modifications to The Floor Plan

If your home is closed off, it might be time to remove some walls, since open-plan spaces have become the thing nowadays. You can do it yourself if you have the skills, but it'd be better to involve professionals, especially if the wall is load-bearing. If it's not possible to remove a wall, rear or side extension are other options. Their only downside is that you'll have to dig deeper inside your pockets. But considering the benefits they come with, they're definitely worth it. 

When you want to sell your home in the future, you want to get a buyer as soon as possible and get the highest prices. You can only achieve this by making it more valuable and marketable. Remember, buying a home is one of the major steps in life, and people are very picky. Adding these updates assures them that they will have a good experience there and mind spending a fortune buying your home.

FLUTTER 2- A Leap into the Future

FLUTTER 2- A Leap into the Future

The major announcement of the Flutter 2 launch was made on March 3rd, 2021, by the Google Developers. It was significant in the sense that the upgrades were many over the previous version.

It enabled the developers to work almost on any platform and, in the process, create and build apps that are more fast, portable, and beautiful. The advantage was that it was a common codebase, and apps can be shifted without any issues and made workable on the top five operating systems.

The operating systems were:

  • Windows
  • Android
  • IOS
  • Linux
  • MacOS.

You can use it to target top browsers such as Edge, Chrome, Firefox, and Safari. As far as portability was concerned, it could easily be embedded in Television, Cars, Smart Home Appliances, thus making its presence felt and an experience in the world of computers.  



It was to introduce a new mindset, especially the Developers' perspective. The 360-degree change Flutter 2 brings around is the experience that has to be created and not the platform itself. In this process, the design is found at the forefront, and branding also occupies an important position.

The advantages of Flutter 2 

  • It is the fastest in compiling the source code to machine codes.
  • And It enables you to make changes with the application still running.
  • It permits you to see the results of such changes in real-time.
  • It is open-ended, thus allowing for many contributors who can enhance the core framework.
  • Flutter is not confined to a mobile framework but also available on a portable one. This helps your apps to run on various platforms with no changes.
  • There are PWA's which Integrate well with the user (like Twitter), and their quality stands enhanced. These enhancements include offline support, installation, and the tailored UX.
  • The web support provided by Flutter to complex standalone apps makes it easy to reach various users on an unrestricted number of devices.

Flutter & the Web:

There is no difference in his Flutter performance on the web compared to the mobile. With the additional flexibility of Flutter and its combination with the web platform's power-building new applications for Android and iOS, the browser is also of the same codebase.

It brings with it many new and exciting additions. They are :

  • Web:

It has helped to leverage web platforms' strength and has thus created a base for interactions between web applications.

  • Sound Null Safety:

It is essential to distinguish between nullable and non - nullable types. Dart language has an add-on through Sound Null Safety. Apps generally crash as there are null errors, but with Sound Null Safety, this is preventable.

Pros and Cons:

Pros:

  • Code writing is faster
  • Testing is lesser
  • Apps work faster
  • Similar code / single code for two platforms
  • User lovable designs.

Cons:

  • Non- availability of certain functionalities
  • As on date, Flutter is not supported by a few CI platforms.

Conclusion:

The advantages of Flutter 2 outweigh the disadvantages. It presents an excellent opportunity for high performance and is capable of satisfying your custom requirements.

Is The Google FI VPN The Best?

Google FI VPN

Google has come out with their own ' VPN' (Virtual Private Network) on all Fi phones to eliminate this. Let us discuss is the Google FI VPN is best or not?

Our dependency on the mobile phone has exceeded all limits, and we are highly dependent on them for many important things. In this process, we are unaware of what repercussions are expected to happen as we pass on vital information.

They may include credit card numbers, passwords, etc., which hackers can conveniently pick up in transit and use for their gains.

What is Google Fi VPN?

Using Google Fi VPN, there are no changes that would affect the process of browsing, streaming, and downloading, with the connection being encrypted and private. In other words, you are given a free run despite the fact you are using insecure networks.

The most significant advantage is that none can locate your IP address, and hackers will have no clue that you even exist.

Found below are improvement made to this process of Google Fi VPN after its introduction:

  • It enables double-layer protection against your Phone number. 
  • Provides complete privacy and more security. 
  • Personal information is completely protected. 
  • Performance improvement but may slow down the existing speed. 

The new Fi VPN does promise this, but are there doubts regarding these claims?

1. Anonymity and protection:

The argument of using the Google Fi VPN is to:

  • Protect ourselves from hackers 
  • Preventing ISP's from collecting all our data and selling to organizations who will benefit from them. 

This is a valid argument provided you want anonymity from your ISP and is justified. But one should never forget that you cannot stay hidden from Google itself.

They would track every movement of yours and bomb you with advertisements in all the products or sites you show interest in!

2. User identifiers and Google's claim:

Google states that any data browsed cannot be traced back to the user. Such a disclaimer does cast doubts because:

  • All your activity is passing through Google. 
  • Google knows where the activity has been initiated 
  • There is no assurance from them that they would not use the information to their advantage 
  • They have the ' know-how' on how to collect your data. 
  • The question then is how much you trust Google. 

3. Speed and performance compromised:

Various VPNs state they aim to provide complete security but not sacrifice the speed or performance you have experienced before. Google, on the other hand, through their Fi VPN, says:

  • All the data will flow through their one channel 
  • There would be increased mobile data which is not less than 10 % 
  • Due to this, the users would' experience slight slowdowns.' 
This is actually in direct contrast to the statement made by other VPNs!

4. Ability to Bypass:

Fi VPN from Google is expected to do wonders on its ability to bypass all restrictions. However, it remains non-committal on bypassing geo-restrictions and blockade from many countries.

The fact is that the Fi VPN cannot change the country of origin, thus allowing the region to block you. The traditional VPN does not suffer from this issue.

Zerologon Bug – Know the Unknown | Mono-Live

Zerologon Bug

We have recently got warnings from Microsoft about a critical vulnerability about which they told in August. We know it as the "Zerologon bug,'' CVE-2020-1472. Now, it has spread in a wide range. Due to which the attackers can hack the database of a company. And they can also remotely control a company's domain.

The bug has affected Windows 2008 and other new updated versions of windows. According to Microsoft, the attackers take the help of the Netlogon Remote Protocol for setting up a secure channel connection with a domain of a company. CISA, known as Cybersecurity and Infrastructure Security Agency, assumes that it can help the attackers to access a network with a domain controller. Zerologon flaw enables hackers to know about the whole network and all Active Directory identity services connected with them.

Recently, CISA has issued an emergency directive in which they have ordered all federal civilian agencies. The identifier of the bug is CVE-2020-1472. Researchers have found a nasty bug in Windows Server which they gave the name 'Zerologon'.

The Active Directory domain controller code has earned a complete ten rating on the CVSS scale. It stands for Common Vulnerability Scoring System. But the details of the controller can never be revealed. It means that users and I.T. administrators are unable to know how dangerous the problem is.

Importance of the Zerologon Bug for the attackers:

The attackers always have a foothold inside the network using which they can target the specific domain with ease. Now, the attackers get help from the post-compromise exploits also. The exploits have become very valuable to the attackers in recent times. 

When they have got some of the previous data, they can easily hack the domains of any company. As soon as the employees click on any links or attachments in the email, the attackers will hack their domains and steal important data.

Using the Zerologon bug, the hackers can quickly get control of the Active Directory. Moreover, you can get free rein to control it.

How Zerologon Bug works:

The Zerologon exploits uses a string of zeros. The attackers send it via the email of any targeted company. When any employee of that company clicks on it, the attackers using the Netlogon protocol to hack the servers of the company's domain. 

But it depends on various tasks like they allow the users to log in. That's why the Administrators need to be concerned about their installing updates. The network components are susceptible. So, you need to be concerned about the updates always.

It is reported that this bug is the most hazardous one comparing to the previous ones. The worth value of it is a 10/10 CVSSv3 severity score. For Microsoft, patching the bug is not so easy a job. It is scheduled in such a way so that it can be run over in two phases. For the first one, Microsoft will help you to let you know about how to fix the first phase. 

 

Microsoft has done this and made the Netlogon security features mandatory. However, if you want to get a more effective patch, then you need to wait till February. The attack made by the hackers was so quick that it only took nearly three seconds or less than that for hacking the domain of the targeted company.

Take over a domain controller with a number of zeros:

People can get in-depth knowledge about the bug from the team at Secura B.V. that is a Dutch security firm. They have published a technical report from where you can know about the CVE-2020-1472. According to this report, we come to know that the bug is precious for its 10/10 CVSSv3 severity score.

It was the Secura experts who named this bug as Zerologon. According to these professionals, it has taken the benefit of a cryptographic algorithm. The attackers used this algorithm in the Netlogon authentication process. 

They use the bug to follow the Netlogon authentication method. It can hide the identity of any computer with ease on a network. Therefore, it will become easier for them to hide their real identity against the domain controller.

By following the Netlogon authentication process, they can disable security features with ease. With the help of the Netlogon authentication process, one can change the password of a computer on the domain controller's Active Directory. Usually, a database of a computer is connected with a domain and their passwords.

The reason why it is named Zerologon is that the hackers attack the database only by adding zero characters in specific Netlogon authentication parameters.

Take over a corporate network within three seconds:

For the beginners, they must need a foothold inside a network to hack the domain. They can't hack the Windows Servers that are not included in the arena of that specific company's network Or belong to the outside of the company's network. It just takes a few seconds to hack all the databases.

The bug can quickly attack anyone's computer of the targeted company and then spread the malware to all computers.

Patches available; more to come

Nowadays, big companies like Microsoft, need to modify their devices that are connected to corporate networks. Now the Netlogon security features become mandatory for this temporary patch in which process the Zerologon got disabled. It is also vital for all Netlogon authentications.

Recently, it has been decided to reschedule the bug for February 2021. People use this name Zerologon for its broad impact, severity, and benefits for attackers. Secura did not release any proof-of-concept code for a weaponized Zerologon attack. In addition to this, the company has also released a Python script instead of the previous script that you have got earlier.

Protecting devices against Zerologon Bug

Microsoft is trying to fix this bug problem in two-phase. During this time, Microsoft has updated the FAQs in its original documentation. This documentation can help you to identify further clarity. It is because a few users are there who found the documentation very confusing.

That's why Microsoft told its users to find out those devices that make vulnerable connections. For this, they said to their employees to monitor event logs, address non-compliant devices, etc. They also said to enable enforcement mode for managing CVE-2020-1472 in their environment.

Companies use Microsoft Defender for Identity, or Microsoft 365 Defender to detect the attackers who try to use the bug against their domain controllers. Microsoft Defender for Identity was known as Azure Advanced Threat Protection. Whereas Microsoft 365 Defender was known earlier as Microsoft Threat Protection. 

Moreover, the Microsoft company is the one that has taken the help of the Cybersecurity and Infrastructure Agency (CISA). They issued some local agencies to look into this matter step by step. Any company that has the Windows Server device needs to patch it for running the server smoothly. This process helps to avoid potential attacks that can steal your database also.

Conclusion:

Microsoft has recently informed its employees to update the domain controllers. And they also told them to find out those devices that are making vulnerable connections. The main focus of the attackers was to get a connection to the domain controller so that they become the domain admin with only one click.
