Hacker hacking Facebook account by tagging in obscene posts, what to do to avoid?

 Hacker hacking Facebook account by tagging in obscene posts, what to do to avoid?

Lately, Facebook account hacking and spreading malware in the form of obscene content has increased.

In this case, first of all, the hacker sends a phishing link to the Facebook user. After clicking on such links, they (the link clickers) account is taken over by the hacker. And from the said account, links to obscene posts are also shared.

In such a post, obscene captions or photos are placed outside. However, there is malware inside. After the hacker takes over the account of other people, he posts such content by tagging more and more friends.

Everyone who is friends with the people tagged in the shared post will see the content. If your friend is tagged in such a post and opens the link to see what's inside, their account will also be taken over by the hacker.

We tested one of the links (shown in the image below) spread by the hacker. After clicking on the link, the access to the account was lost. After that, the account was immediately brought back by changing the password using the 'Forget Password' option.

Thus, as soon as the link is clicked, the lost account can be restored at the initial stage. If the password is not recovered immediately, there is a risk that the access to the account may be lost forever.

After the excessive reports on the tested link, the link is currently down. However, Harak is spreading malware by creating many other such links.

How to avoid such an event?

The most important thing is that even if it is a link sent by your friend, you should not click on the link unless you are confident about it. If you have received a link on messenger, call and understand about the link.

If we look at this current event, the Facebook tag is seen as a major challenge. If you have turned on the feature that automatically accepts Facebook tags, you may not know that you have been tagged in such posts.

So adjust the settings so that you know before the post tag. You can follow the below procedure for that.

- First open the Facebook app.

- Then go to the profile icon on the top right.

- Then, click on the settings icon below it.

- After doing this, go to Profile and Tagging (Profile and Tagging) option.

- If you want no one to tag you on your timeline, go to the Who can post on your profile option and select the Only me option.

- Similarly, go to the option of who can see the posts that you're tagged in (i.e. who can see posts that you're tagged in your profile?) and choose the option that suits you. In this case, you can choose the friend option.

- After doing this, go to the section of Reviewing and turn on the option of Review posts that you're tagged in before the post appears in your profile.

If you do this, you will get a notification about who tagged you. If you want to show that post on your Facebook profile, then tap on the 'Add to Profile' button. But if you want to remove the tag request, you can press the 'Hide' button. If you don't want to remove it or show it on your profile, you can just leave the post.

What to do when the tag is done?

Suppose, the tagging feature in your Facebook account is not turned on and somehow the post appeared on your profile. Even in such a case, you can disassociate yourself from the tagged post. For that you can follow the below procedure.

-First go to your profile.

- After going to the profile, open the post you are tagged in.

- Then, tap on the button with three dots on the right side.

- Tap on the remove tag option above the last one.

This way you can remove yourself from the post you are tagged in.

Pay attention to account security

The Facebook account you are using can be taken over by others at any time because of you. If you click on a malware link in your inbox or click on a link tagged to others, a hacker will gain access to your account.

Sometimes it may happen without you knowing. In that case, the hacker is looking for an opportune time to abuse your account.

It is best to recover your account before the hacker abuses it. But it is not always possible to recover like this. Therefore, it is wise to take measures to keep your account safe beforehand.

The most important thing for this is to make a habit of changing your Facebook password frequently. Also check who has the recovery email or phone number in your account from time to time.

Sometimes someone else may have access to your account and put a different phone number and email on it.

Thus, if you follow the security methods mentioned above, you can stay safe on the social network Facebook.

What is the end-to-end encryption you see in Messenger?

Recently, the end-to-end encryption feature has started as a default feature in the Messenger app of social network Facebook. Previously, the company has made the feature that the user has to manually update according to the need, saying that it is suitable for the user's privacy. So what is the end-to-end encryption feature and why is it useful for users? Today we are discussing this topic in detail.

do you know From the moment you open your smartphone or other smart device and access the online world, your data is being tracked by many parties. The data you provide to various platforms is sold by those companies or platforms to various parties seeking to serve you advertising.

In some cases such data falls into the hands of hackers and they try to gain access to every system of yours. Some reliable smartphones are providing protection by setting up a strict security system in view of this security weakness. However, even such phones cannot provide any kind of security to the data you provide on the Internet.

However, it is impossible to prevent anyone from accessing the data you have stored online. However, to keep your data safe, you can turn it into a code that no one but you can understand. Yes, this is why 'encryption' has proved to be the backbone of online communication.

Your communications with different people or companies online should be based on end-to-end encryption to ensure that they are not accessed or read by hackers, government agencies or dangerous parties.

So what is end-to-end encryption? Why should we care about this while talking online or transferring some data? Today we are giving detailed information about end-to-end encryption.

What is encryption?

Before understanding what end-to-end encryption is, we must understand its basic aspects. Encryption is a system that transforms any data in such a way that the unwanted party cannot easily understand that data. And, the said data can only be understood by the official party.

For example, suppose you try to send a message to one of your friends. The message you send does not reach your friend's device directly. After you send a message, the message is shared with various online infrastructure such as; The message finally reaches your friend's device through the internet service provider, the messaging app's server, and various parties connected between you and your friend.

The messaging service provider uses a mathematical cipher algorithm to encrypt the data to ensure that no matter who is in between, they have not read your message.

Where the said algorithm converts the simple message text sent by the user into cipher text. Cipher text refers to a structure of letters, which has no specific meaning. The meaning of saying turns into some kind of code.

In this way, the message converted into ciphertext is converted into a real message by means of the decryption key. This means that even if a hacker gets access to the message transmission system, they cannot understand the meaning of the message. Since they do not have the decryption key, they cannot understand such messages.

Sipper text is also known as Caesar's Sipper. Because first of all, the Cipper text was prepared by Julius Caesar. This is a process where the message is placed in different letters using a substitution algorithm.

Each letter of the message is substituted and connected to another letter of the alphabet. For example, if one uses shift three of the substitution algorithm, then A is denoted by D, B is denoted by E in that letter. And other letters are also encoded in the same way.

Now in the age of computers, it has converted billions of bits of data per second into crisp text. The simple Sipper algorithm that was used earlier has now been replaced by complex mathematical algorithms.

Even though the system has changed, the basic working principle remains the same. There are many types of encryption algorithms in use today. Which has its own advantages and challenges.

Public Key or Private Key of End-to-End Encryption End-to-end encryption is a type of encryption where the message is encrypted as soon as the sender (sender) sends it and decrypted before it is received by the receiver (receiver). .

After the message is sent by the sender, it is encrypted until it is sent by another person. That is, the message is encoded as soon as you send it and is only decrypted when it reaches the other person.

Even if anyone can see the message during this transmission, no one can understand what is written in the message. This is the true meaning of end-to-end encryption.

Messenger encryption and decryption work is done only at the end of sending and receiving messages. When the message is in transit (broadcast), the message is neither encrypted nor decrypted.

It means that as soon as the message is sent, it is encrypted and converted into a code and the same code is transmitted in between. Then finally the other person gets the message At the last time, the encrypted code is decrypted. And the recipient gets to read the actual message.

End-to-end encryption uses 'asymmetric public key' (Asymmetric public key) encryption. Where both parties have two keys. A key here means a key, which is used by a mathematical algorithm to encrypt or decrypt a message. There is a public key. Anyone can access it.

However, private or private keys are those that are not shared with anyone. The public key is used to encode the message while the private key is used to decode the encrypted message.

When someone wants to send you an encrypted message, the application they use uses the public key to encrypt the message. The encrypted message is transmitted through the Internet.

A message cannot be decrypted or translated into intelligible words by means of a public key, even if anyone can find it. This means that the real message cannot be known through public encryption.

In order to view the message, the private key is required. Here public key and private key are connected like this. So it is not possible to see or read the actual message with the help of public key only.

Advantages and disadvantages of end-to-end encryption

As mentioned above, each type of encryption has its own advantages and challenges. End-to-end encryption has many advantages and challenges.

This means that there can certainly be some challenges when you use end-to-end encryption.

advantage

In end-to-end encryption, data is encrypted or decrypted only at the end point, making it almost impossible for hackers or government agencies to view your data.

It can be especially useful for journalists, activists and ordinary people who want their conversations to remain private.

Previously, when you sent a pirated link without turning on encryption in Messenger, Metaco's system knew that you had sent a risky pirated link.

And, it was stopped before it reached the person you sent it to. However, now such a message reaches the user directly. Of course, Facebook does not know what kind of link or message you sent. However, if you report the message, Meta will look at the message and if it finds it wrong, it will ban the account you reported. Its more advantages and disadvantages are discussed below.

-Privacy

Your privacy is protected when messaging or storing data on a platform with end-to-end encryption.

- Security

No government agency can force the service provider to show your private messages. Because no one has access to the decrypted chat. So your message is safe.

- Reliability

End-to-end encryption ensures that no one but the sender knows that you have received a message.

- Secure remote work

After the Covid-19 epidemic, the trend of working mostly at home increased. For companies, end-to-end encryption helps ensure that data exchanged by employees is secure.

Disadvantage

-Use more resources

The platform uses multiple resources to implement end-to-end encryption to keep user data safe. Because to encrypt data and decrypt it again, a large amount of data needs to be transferred, so a lot of resources are needed.

-Monitoring is reduced

If different users have sent messages using the end-to-end encryption feature, it is not possible to regulate such messages. Therefore, groups or individuals with wrong intentions use these features more.

-Lost data is not recoverable

If data is stored on platforms with end-to-end encryption or if messages are sent from such platforms, lost data cannot be recovered. Since the data is encrypted in the middle, it is almost impossible to decrypt such data.

-You know who you're talking to

Even if you don't know what you're talking about, the various parties in between may know who you're talking to.

Apart from Messenger, which app has end-to-end encryption?

Recently, most of the messaging apps and data storage apps in the market have encryption service.

If you also want to send an encrypted message or want to receive an encrypted message, you can use platforms like Signal, Threema, WhatsApp, Telegram, Wire, Google Message. 

Live video chat can now be done on X too

The video feature will be added to the space of social network X. The owner of the company, Elon Musk, has informed that the feature will come soon on the platform.

Xma Space is a live chat feature that any user of the platform can join. Earlier, the platform had the facility to communicate through audio. With the inclusion of the video feature, users can now join the space through video.

"We're working on adding a video feature to the space right now," Musk said, "it's a simple thing where you can turn video on and off."

Although Musk is preparing to release this feature at the end of 2023, it is expected to be available at the beginning of 2024.

In a space session, the video feed switches to the person who is speaking. For example, like the user who is speaking in Google Meet, his video is shown on the big screen. The feature is also expected to work in the same way in X.

“This feature is useful to see the body movements of people while they are speaking. If they want to, facial expressions and body language convey more information than voice," Musk said.

The company believes that this feature will help more to interact with the audience. Twitter launched the space feature to compete with Clubhouse, an audio streaming platform that emerged during the Covid-19 pandemic.

Musk hasn't changed much in the space since taking ownership of Twitter. Now it is said that he is going to release a video feature to bring the same feature into the limelight.
