The Importance of Strong Passwords in Cybersecurity || Read full details here

Introduction




In today's digital age, where we store and access sensitive data online, password security has become increasingly important. A strong password is the first line of defense against hackers and cybercriminals who are constantly trying to gain unauthorized access to personal and sensitive information. In this article, we will discuss the importance of strong passwords in cybersecurity and provide tips for creating and managing strong passwords.


The Problem with Weak Passwords





Weak passwords are easy targets for cybercriminals. They can use various tools to guess or crack passwords that are too simple or commonly used. Moreover, reusing passwords across multiple accounts or sharing passwords with others can put your sensitive data at risk. According to a recent survey by NordPass, "123456" and "password" were the most commonly used passwords in 2021. This shows how many people still do not take password security seriously.


Characteristics of Strong Passwords





A strong password is characterized by its length, complexity, and uniqueness. The longer the password, the harder it is to crack. A good password should be at least 12 characters long, with a mix of uppercase and lowercase letters, numbers, and special characters. For example, "P@ssw0rd!23" is a strong password that is difficult to guess or crack.


Best Practices for Creating and Managing Passwords





Creating and managing strong passwords can be challenging, especially if you have multiple accounts to manage. Here are some best practices to follow:


  • Use a password manager: A password manager is a tool that helps you generate and store strong passwords for each of your accounts. This way, you do not have to remember all your passwords, and you can access them easily.

  • Enable two-factor authentication: Two-factor authentication adds an extra layer of security to your accounts by requiring a second form of identification, such as a code sent to your phone or email.

  • Change passwords regularly: Changing passwords every few months is a good practice to follow, especially for accounts that contain sensitive data.

  • Use different passwords for different accounts: Using the same password across multiple accounts can put all your accounts at risk if one of them is compromised.

  • Do not write down passwords: Writing down passwords on paper or in a file on your computer can make them vulnerable to theft or hacking.

Password Security in the Workplace




Password security is especially important in the workplace, where sensitive data is often stored. Companies should implement best practices to ensure that their employees are using strong passwords and keeping them secure. These include:


  • Educating employees on password security best practices.

  • Requiring strong passwords and regular password changes.

  • Implementing two-factor authentication.

  • Monitoring password usage and enforcing security policies.

Conclusion


In conclusion, strong passwords are critical to protecting personal and sensitive information from cybercriminals. By following the best practices for creating and managing strong passwords, you can reduce the risk of being hacked or having your data stolen. We encourage you to take the time to review your passwords and make any necessary changes to ensure your online security. Remember, a strong password is your first line of defense against cyber threats.

Safeguarding Your Business Against Ransomware Attacks: All You Need to Know About Unpatched VMware ESXi Servers

 

Introduction












Ransomware is a malicious type of software that is used to extort money from victims by encrypting their data and demanding payment for its release. This type of attack has become increasingly common in recent years, with a recent ransomware attack targeting the popular VMware ESXi servers used by hosting service providers. In this blog post, we will provide an overview of ransomware and its effects, as well as an in-depth look at the ESXiArgs ransomware attack, its potential vulnerabilities, and what technical measures can be taken to mitigate it. We'll also provide tools and resources to help protect against ransomware attacks.

What is Ransomware?











Ransomware is a malicious software that is used to lock users out of their digital devices or networks until they pay a ransom. It is mostly used by cyber criminals to make money, but it can also be used as a form of political protest. When ransomware is installed on a device or network, it encrypts all the files and data stored on it and then demands a payment in exchange for the decryption key.

Ransomware can have a serious impact on its victims, especially if it is used to target a hosting service provider. Not only can the data stored on the infected device or network be lost forever, but the malicious software can also spread to other systems, putting other users at risk. Additionally, those who pay the ransom may never receive the decryption key, and their data is still at risk of being lost. It is important for users to secure their systems by keeping them up to date and backed up, as this can help protect them from ransomware attacks.

How does a Ransomware Attack Work?

Recently, a massive ransomware attack has been targeting unpatched VMware ESXi servers, leaving many hosting service providers vulnerable to malicious hackers. Ransomware is a type of malicious software that encrypts data or locks computer systems for the purpose of extorting money from victims. It is important to understand how ransomware works and the steps it takes to encrypt a system.

Ransomware is typically delivered through email phishing campaigns. It could also be installed through malicious websites, software downloads, or even via USB flash drives. Once the ransomware is installed, it will begin to scan the system for files and encrypt them using a code that only the hacker knows. The encrypted files will be inaccessible until the victim pays a ransom to the hacker.

If a system is infected with ransomware, it is important to take immediate action. The first step is to disconnect the system from the network and any other connected devices. The next step is to back up any important files that have not already been encrypted. Finally, it is best to consult a professional to see what steps should be taken to remove the ransomware and restore the system.

What is VMware ESXi and why is it vulnerable to Ransomware Attacks?

VMware ESXi is a virtualization and cloud computing platform designed to run on physical servers. It allows administrators to manage multiple operating systems and applications on a single server, helping to reduce hardware, energy, and maintenance costs. Unfortunately, VMware ESXi is vulnerable to ransomware attacks due to its lack of security patches.

Ransomware is a type of malware that encrypts files, making them inaccessible to users. In the case of VMware ESXi, attackers exploit the lack of security patches to gain access to the system and install ransomware. Once installed, the ransomware will encrypt the user’s data and demand a ransom for its release.

For hosting service providers, VMware ESXi is a crucial tool for setting up virtual servers. By leveraging the cloud computing capabilities of the platform, service providers can deliver a wide range of services to their customers. However, the risk of ransomware attacks has made it necessary for hosting service providers to ensure that their VMware ESXi servers are properly patched and secured against such threats.

New ESXiArgs ransomware

A new strain of ransomware, called ESXiArgs, is targeting hosting service providers running VMware ESXi systems. This is a particularly insidious form of ransomware since it is designed to exploit unpatched vulnerabilities in the ESXi operating system. By taking advantage of these flaws, ESXiArgs can disable the server, encrypt all data and then demand a ransom payment to restore the server and data.

ESXiArgs ransomware is different from other ransomware attacks in that it specifically targets hosting service providers. By exploiting vulnerabilities in the ESXi operating system, ESXiArgs can disable the server, encrypt all data, and demand a ransom payment to restore the server and data. Additionally, ESXiArgs is unique in that it requires an initial payment to the attacker in order to unlock the encrypted data.

It is important for all businesses and organizations to understand how serious ransomware attacks can be and take steps to ensure that their systems are guarded against them. Ransomware attackers have been known to target vulnerable systems with relentless determination, often leaving companies and individual users facing hefty bills or even complete system wipes if they do not pay up. By making sure all systems are kept up-to-date with the latest patches and security updates, organizations can reduce the risk of attack significantly. Additionally, regularly training staff on potential threats is another way to help mitigate risk.

ESXiArgs technical details

A new variant of ransomware, dubbed ESXiArgs, has been discovered recently targeting unpatched VMware ESXi servers. The ransomware encrypts data stored on the server, preventing its use unless a ransom is paid. It is believed to be delivered through an exploit of the unpatched server, allowing hackers to gain access and deploy the malicious payload.

ESXiArgs works by encrypting data stored on the server, making it impossible to access until a ransom is paid. It is believed to be delivered via an exploit of the unpatched server, allowing the hackers to gain access and deploy the malicious payload. The ransomware encrypts data with a strong encryption algorithm, making it nearly impossible to decrypt without the encryption key.

To protect against ESXiArgs ransomware, hosting service providers should ensure that their servers are up to date with the latest security patches. Additionally, administrators should monitor for any suspicious activity on the server and back up data regularly to ensure that it can be recovered in the event of an attack. Lastly, users should take steps to ensure that their data is encrypted and stored in a secure location to minimize the risk of losing access to their data.

How to Protect Yourself from Ransomware Attacks

The recent massive ransomware attack targeting unpatched VMware ESXi servers has been a wake-up call for hosting service providers to ensure they have taken the necessary steps to protect their customers. To protect yourself from ransomware attacks, it is important to have the right tools and resources in place. These include firewalls, anti-malware software, and regular backups of your data. Additionally, you should ensure that all your operating systems, software, and applications are regularly updated and patched. Finally, you should be aware of phishing emails and other scams that are designed to infect your computer with malicious software.


In the case of the ESXiargs ransomware attack, it is critical that organizations apply the latest patches to the VMware ESXi software. The patches address the vulnerability that is being exploited by the attacker, making it much harder for them to gain access to the virtual machines. Organizations should also take the following steps to protect themselves from this attack:


  1. Back up important data and virtual machines: Regularly backing up important data and virtual machines is one of the most effective ways to protect against a ransomware attack. In the event of an attack, organizations can restore their virtual machines and data from the backup, minimizing the impact of the attack.


  1. Implement multi-factor authentication: Implementing multi-factor authentication can make it much harder for attackers to gain access to systems. This added layer of security can be applied to both physical and virtual machines, adding an extra layer of protection.


  1. Monitor network activity: Monitoring network activity can help organizations detect any suspicious activity on their network. This can include unusual network traffic, login attempts from unknown IP addresses, and unauthorized access to virtual machines.

  2. Implement security software: Implementing security software such as antivirus, firewalls, and intrusion detection and prevention systems can help organizations detect and prevent attacks. These tools can help organizations identify and block malicious traffic, reducing the risk of a successful attack.


  1. Train employees on security best practices: Training employees on security best practices can help organizations reduce the risk of a successful attack. This can include training employees on how to identify phishing emails, how to handle sensitive information, and how to report security incidents.

Conclusion

The recent ESXiArgs ransomware attack highlights the importance of keeping systems up to date and secure. Hosting service providers should ensure that their VMware ESXi servers have the latest security patches applied, as well as use additional measures such as firewalls and monitoring solutions to help detect and prevent ransomware attacks. Additionally, regularly backing up data and keeping security software up to date can help protect against data loss due to ransomware attacks.

 The ESXiArgs ransomware attack specifically targets unpatched VMware ESXi servers and exploits the vulnerability CVE-2021-21974. Admins and hosting providers must take immediate action to disable the vulnerable SLP service and apply the available patch to prevent a compromise. Those who have already been affected should follow the guide provided by the security researcher to rebuild their virtual machines and recover their data.

Reasons not to buy Google Pixel in India



Well about 2 years back I write a blog for reasons to buy a google pixel in India [check that here] but as I've used the device over the years I get to know somethings that make the device just unbearable. I'll break them down to certain points for easy understanding.

Let me make this perfectly clear here and now I proudly own a pixel 4a and still using it and loved every minute but I believe people of India needs to know somethings about pixel phone before they actually buys the device. So, Lets get into this


1. Price: Google Pixel phones are known for their high price points, which may be considered excessive when compared to other smartphones available in the Indian market. Even though the pixel ‘a’ series is considered as a budget segment but still for some people they aren't really be considered as budget.

2. Limited availability: Google Pixel phones are not widely available in India, making it difficult for some consumers to purchase them. Most of the time the phone is not available on the online websites. And the availability in offline market is very limited to very few stores.

Google Pixel availability is at very specific places


3. No expandable storage: Google Pixel phones do not have a microSD card slot for expandable storage, which may be a deal breaker for some users. To be quite honest iPhones does the same thing and people don’t really have a problem with it so I don’t think it is going to be a deal breaking point but still for some obvious reasons if they put a SD card slot I love to have it.

There is no storage variant only 128 GB is available


4. Lack of support for Indian bands: Some Google Pixel models may not support all of the Indian cellular bands, which could lead to connectivity issues for some users. Well I don’t face any problem what so ever but I read some online articles people do face some problems. But later, they fixed with the updates, I think.

5. Limited after-sales service: Google may not have an extensive after-sales service network in India, which could make it difficult for users to get their phones repaired or serviced if they experience any issues. To be honest when I first get to know about this it is quite sad as when anyone buy a Google devices they must be expect the great after sales service similar to apple which is quite popular in India. If a person need some after sales support it can only be done via third party and the repair only be done in Mumbai I think. So, if a person lives not in Mumbai, they need to send the device through courier so basically it may take months or few weeks it quite depends on but that is not what a person buys a device for or expect this kind of after sales service.

Loading!!!!
No official service center in India.


To be honest these are only some points that I can think of there are lot others as well like there is very limited to no customization. When I first heard about android 13 update I though it will completely change the customization for the phone but after the update only limited things I can see.

Conclusion

I can’t say these are the points applied to everyone but these are some points that change the decisions to most of the people look as a consumer I always look for these points. I’m extremely upset with the after sales service if I ever need the to be repaired but that is not happen yet and I want to keep it that way. And another thing I want to add is I love the google chat support like if you are facing any kind of trouble google application just go to the chat support and they’ll actually help you which seems nice for a company who don’t provide after sales service to its customer

Worlds Safest Password : "Password" || Read all Details here

Okay first of all the title of this blog is really a understatement and second most people think that how is this possible maybe the writer is idiot or something well I won't blame you but first read this blog then decide about me. I'll try to make my explanation as easiest as possible. So lets get started

Well first of all I fully support my title that Password is actually the safest password but there is also a catch in this.

Now first of all just think about it how a password cracking work :

it take a single alphabet or number or special character and calculate all the permutation and combinations right. Okay so if some people still don't understand let me give you an example :

Ex: suppose you password for an account is "PasswOrd" okay so basic password cracking tool simply apply a to password field afcose it won't work same way then b is tested all the to z now. Do keep in mind only small letters are tested. Now all the upper case alphabets are tested A to Z but as of this movement nothing works now Both 2 letters are combined ab are tested all the way to az which doesn't work similarly after many attempts password will be cracked. 

That's basically overall the password cracking tools work mostly. Now back to my statement how the word "password" is actually the safest password. 

Total possible combination for word password is 6435 and that is only for small alphabets. Now as I add the special characters, numbers, upper case alphabets the total number for combination will increase.


Now afcose many readers also thinking about that since now this whole password cracking process is automated what's the point of all this. Well that's a brilliant point and also correct in its own sense but just think about it any website for password cracking always has a limit for wrong password. 

Basically a user will only enter a wrong password for a certain number of times so even though the tool is fast enough but still doing all the combination isn't really possible for many tools. 

I fully agree that having password as password isn't really the most safest thing to done atleast from security point of view but still having password as password is more like a wild card it has good and also worst side..

Apart from that in this era no one really care to put password as password since there are password managers that saved the password and also make or suggest new strong password that are combinations of all the words, numbers and special characters and that is super easy to use but just think about storing your password at one single place is safe? Well I don't think so since if buy any chance the hacker gain access to this manager and that'll immediately provide access to all your accounts. I understand cracking the software isn't easy but it is not impossible as well.

Now,  at last I agree that many readers may actually still challenge my statement and I agree with them yes they're absolutely correct but even they also know that my points I explained above aren't completely wrong either. So ultimately all I can say is for better security don't just relay on passwords managers since a single vulnerability can give access to all accounts in one go.

I use this tool to calculate all the combinations for password. It is a free online tool.
