Beware: 250 million smartphones are in big danger by trojan malware

Smartphone Hacking: If you also keep a smartphone, then this news is going to warn you. Actually, a cybersecurity company has asked smartphone users to be careful. A cybersecurity company called Kaspersky Labs has detected a virus, being told that the virus cannot be easily deleted.

With this virus, now around 250 crore smartphones worldwide are under threat. The company said that this malware can always be present in smartphones. By this, hackers can steal your personal data. This vicious move of hackers has put the threat of more than 250 crore Android smartphones all over the world.

Kaspersky Labs company has discovered this malware named xHelper on the unofficial app marketplace. The company said that the hackers cleverly use this malware to steal the data of users. It is being transported in people's mobiles through a fake Cleaner app.

The most worrying thing is that this app hides after being installed on the phone. You can see it neither on the home screen nor in the program menu. You can see this dangerous app in the list of installed apps only by going to Android system settings.

The company said in a post that it came to know about this malware threat after checking the sample Trojan-Dropper.AndroidOS.Helper.h. 

This malware is so dangerous that it accesses all the user's data after the backdoor is installed. When the user tries to uninstall the app or malware, it is automatically installed again.

According to experts, another malicious program is installed in your phone with this malware, even after deleting it, reinstall xHelper. However, cybersecurity experts have definitely suggested a way to remove it from the phone. You have to set up recovery mode on your Android phone. After this, you can replace the libc.so file with the original firmware and replace it with the infected file.

What is Malware

The term malware is compression of malicious software. Simply put, malware is a piece of software that was written with the intent of damaging devices, stealing data, and generally causing disturbances. Viruses, Trojans, spyware, and ransomware are among the different types of malware.

Malware is often created by teams of hackers: usually, they are just looking to make money, either by spreading the malware themselves or selling it to the highest bidder on the Dark Web. However, there can be other reasons for creating malware - it can be used as a tool for protest, a way to test security, or as a weapon of a war between governments.

Types of Malware:

1) Computer worm:

Worms also prepare and spread their replication more actively than viruses based on other files. Computer worms use removable media or networks to gain access to other systems and typically require a program to assist them in this task. Worms that spread through e-mail use the e-mail program of users to send themselves to all the addresses in the address book. Like viruses, Worms can damage systems and are often used to gain covert control over computers. Worms are considered the most common type of malicious software.

 2) Computer viruses:

Viruses are programs that are capable of spreading differently by making copies of themselves and then infiltrating other computer programs. A virus is the best known and oldest type of malware. A virus multiplies after the virus program starts, and then interferes with the computer's functions, spying on users, destroying data, or even damaging the hardware.

3) Trojan horse:

Trojan horse is a type of malware that initially pretends to be a useful and secure application so that it can access a computer's system. It performs functions that are mostly hidden from users. Trojan horses can carry out many harmful actions such as monitoring the data traffic of a computer. Some of these actions take place with the copying and sending of information or files, while others execute special tasks on the computer in addition to replacing or installing new software. It is also possible to remotely control Trojan horses through a backdoor function, which allows other users the opportunity to hijack the computer for cybercriminal purposes.

4) Adware:

The term adware is considered to be a contraction of advertisement and software and is operated by placing advertisements in the program. It is usually included in free software and is mostly legitimate, but it can also be dangerous if it shows a pop-up or fake website, or makes any changes to the system or browser settings without permission.

5) Spyware:

This type of malware is used to uncover user data and send it to the manufacturer or a third party. Even when Spyware comes into the PC, the user is completely unaware that their behavior is being recorded. The information obtained by spyware is mostly analyzed for commercial purposes to show customized advertisements for example.

6) Ransomware:

The software goes one step ahead of the software by blocking access to the computer's operating system or blocking critical files. This program demands payment of a ransom to withdraw the blocked data.

7) Scareware:

This malware focuses on scaring and harassing users by displaying fake warnings about malware discovered on computers. If an advertisement for fee-based software appears in a pop-up on your PC that claims to be able to remove your PC's alleged malware, it is known as rogue security software or rogueware. If the user buys this allegedly useful application and installs it, then a lot of malware will usually appear on the computer.

 8) Backdoor:

Backdoor is also known as a trapdoor. It is a function rather than an independent program. A part of the software is known as a backdoor when an external user succeeds in accessing the computer. This happens without the knowledge of the users. Often, remort access is used to perform service-related attacks, which occur when Internet services perlize or send spam e-mail. Backdoors can be installed by Trojan horses, viruses, or worms.
