5 Things to Do When Ransomware Attacks

It is your average weekday morning, you walk into your office, open your laptop, and you suddenly find out that all your files have been encrypted.

You proceed on to figure out what has happened, and you see a text file or an email that tells you your data has been locked, and you will get it back only if you pay a ransom. If that is the case, you have been attacked by a computer malware called Ransomware.

It is highly dangerous, and it will lock down the files on any computer it enters. If your computer has been infected with, there is no need to panic. You need to do these things quickly to make sure all other computers do not get infected:

1. Analyze Your Situation

The initial thing you need to do is analyze how this ransomware attack has affected you. The source of the virus could be several things. You do not necessarily have to click on something to get these viruses these days.

In some cases, you will be able to recover the files by using a ransomware recovery tool, while in other cases, you will have to get your files from the backup data.

In some cases, if the data is too valuable, you may have to consider paying the ransom as well. But to control the damage, make sure that you tell everyone at the workplace that your computer has been infected so all of them can take precautionary measures.

2. Lockdown Your Computer

The close thing you need to do is make sure that your computer is not connected to the server, and you are taking all the files you shared offline. If you did not click on the virus, you could also see your shared history as it can help you identify the source of the malware. If a particular user has opened too many shared files, it is highly likely that they are the source.

3. Shut Down the Source

While it can be a difficult thing to do in an organization, you will need to shut down the source user of the virus. It could be anyone from a senior position to junior level.

The IT personnel must be given the required permission to access that user’s computer and should track all the infected users before shutting the source down. It is essential to identify the source because this could help you limit the damage. If you start worrying about restoring files immediately, there is a high chance other computers will start getting infected.

4. Identifying the Type

There are several different kinds of ransomware viruses. To determine yours, you will have to look for the text file that the attacker left on your PC. You can use the screenshot of that file to scout the internet as there are a lot of communities out there that deal with ransomware discussions. Once you have identified the ransomware-type from that file, you will be able to move to the final step of recovery.

5. Verifying Backup or Paying the Ransom

Now once you have figured out the type of Ransomware, you can try to decrypt files by using software, but if it does not work, you are left with two choices. You can recover the backup data, or you can pay the ransom. For that, you will have to see how long it will take for the computers to recover the backup data and how efficiently it will do it.

You might end up losing some files, and your company will have to work a little hard to recover that difference, but instead of paying the ransom, this is the right thing to do.

What is LCM, and how it is used in real-life situations

The topic of LCM and HCF holds tremendous significance in mathematics. HCF and LCM are the basic building blocks in various math topics. The fundamental knowledge of this topic helps students to learn complex problems and issues quickly. Students need to understand the applications of these concepts to understand their relevance and usage in their life. Cuemath enables kids to learn various math concepts along with their real-life applications with ease.

HCF and LCM play an essential role in number theory and various other topics like prime factorization, permutation, combinations, etc. These topics require absolute numerical rigour and can be easier to understand if the fundamentals are clear.

1. What is LCM, and how it is used in real-life situations:

LCM (Least common multiple) is the least number which is exactly divisible by each one of the given numbers. It is used to solve problems related to racetracks, traffic lights, to predict when an event occurs again over the same period and so on. Here are some ways the concept of LCM is applied in our everyday life:

Repetitive tasks and events: The traffic controllers have to set the timings of traffic lights so that all lights are not green simultaneously, especially in the busy day timings. As this may create problems and they have to be set for a few minutes only. A traffic controller takes the timings of nearby places in the same area and calculates the LCM of all traffic stops to set the timing for each signal. This way, he can easily manage the traffic by setting alerts at different times or by increasing/decreasing the duration of each movement.

Solving Fractions: The basic concept of LCM helps in arithmetic for solving fractions. For infractions with different denominators, we have to bring both of them to the same denominator to solve them. This requires first bringing them to have a common denominator by using LCM.

Think out when something will happen again at the same time. It is used to figure out something that will happen again at the same time. For example, it is helpful to send rockets and space shuttles to planets when they’re the nearest to earth.

Encryption: LCM of substantial prime numbers is also helpful in RSA encryption techniques to send the information securely over the internet connections.

There are many more real-life and mathematical, and real-life examples that apply the concept of LCM.

What is HCF, and how it is used in real-life situations

2. What is HCF, and how it is used in real-life situations:

HCF (Highest Common Factor) is the most significant number that can divide the given numbers without any remainder. It is used to split things into smaller sections, arrange something into rows or groups, distribute more numbers of items to large groups, figure out how many people we have to invite, and so on when we want to split things into smaller sections.

Practical Estimation: When you plan for a party and want to ensure that nothing gets wasted or you need a proper estimation, you can use the concept of HCF to figure out the same.

Equally, distribute things: HCF is a required method that enables you to spread things equally among a group or set. Let’s consider the example of distributing 20 chocolates and 40 sweets amongst ten children, so here we will give each child two chocolates and four sweets.

Optimization of resource: You can use HCF to estimate the minimum number of square towels that can cut from a ream of cloth of a certain length and width without wasting any fabric.

Arrange something in rows and groups: To solve space issues, efficiently stock two or more quantities of different dimensions; you can use HCF of the amounts to decide and implement.

Learning the concept of LCM and HCF comes quite handy while pursuing higher studies in Mathematics and other related fields. Having a conceptual understanding of these techniques can be pretty beneficial in planning, estimating and dividing things.

Learning the real-life applications of these concepts enhances problem-solving and critical thinking in kids. Cuemath enables kids to grasp various math concepts and their real-world application with ease. It provides multiple learning resources and interactive activities to aid visualized learning and problem-solving mindset in kids.
