What is Malware?
Malware comes from words malicious software, is a catch-all term for viruses, worms, trojans, and other malicious computer programmes used by hackers to cause havoc and get access to sensitive data.
Types of Malware?
Malware is classified in several ways. The way malicious software spreads can be used to distinguish it. The terms virus, trojan, and worm are often used interchangeably to represent three subtle differences in how malware might infect target computers:
Worm is a piece of malicious software that replicates and spreads from one computer to another.
Viruses are pieces of computer code that embed themselves in the code of another standalone programme, forcing it to perform malicious actions and spread themselves.
Trojan is a programme that can't replicate itself but disguises itself as something the user desires, tricking them into activating it so it may cause harm and propagate.
Malware can also be placed "manually" on a computer by the attackers, either by physical access or through privilege escalation to achieve remote administrator access. Another approach to classify malware is by what it does after infecting the systems of its victims. Malware can employ a wide range of attack methods, including:
1-Spyware is defined by Webroot Cybersecurity as malware used for the purpose of secretly gathering data on an unsuspecting user.
2-Rootkit is a programme or, more commonly, a set of software tools that allows a threat actor to remotely access and manage a computer or other system.
3-Adware is a type of malware that causes your browser to be redirected to web adverts, which frequently attempt to download more dangerous software.
4-Ransomware encrypts your contents on your hard drive and demands a payment, usually in Bitcoin, in exchange for the decryption key.
5-Cryptojacking is another way attackers can force you to supply them with Bitcoin only it works without you necessarily knowing.
6-Malvertising is the use of genuine advertisements or ad networks to distribute malware to the systems of unwary consumers.
How to prevent it?
The easiest method to avoid malware is to ensure that your email systems are well-protected and that your users are aware of potential threats. There are a lot of technical preventative measures you can take, like keeping all of your systems patched and updated, keeping an inventory of hardware so you know what you need to secure, and conducting ongoing vulnerability assessments on your infrastructure. When it comes to ransomware attacks, one way to be prepared is to keep regular backups of your information, ensuring that you'll never have to pay a ransom to recover them if your hard drive is encrypted.
Protection?
Install the anti-malware software to protect your device. We list the best antivirus:-
F-Secure PSB Computer Protection
Kaspersky Endpoint Security
Seqrite Endpoint Security
Symantec Endpoint Protection
Trend Micro Apex One
How to detect it?
Step by step, do this now for all Windows computers:
Make sure your computer has an active connection to the internet.
Go to Sysinternals.com. It’s a Microsoft site.
Download Process Explorer and Autoruns. Both are free, as is everything on the site.
Unzip these programs. If using Process Explorer, use procexp.exe. If using Autoruns, use autoruns.exe (autorunsc.exe is the command-line version).
Right-click and run the program executable as Administrator, so it’s running in the Administrator’s security context.
Run Process Explorer first (I'll explain Autoruns later). Select the Options menu at the top of the screen.
Choose VirusTotals.com and Check VirusTotals.com.
This will submit all running executables to the VirusTotal website, which is run and maintained by Google. You’ll get a message to accept the license; answer Yes. You can close the VirusTotal website that comes up and go back to Process Explorer.
In Process Explorer, you'll see a column labeled Virus Total. It will either say Hash Submitted (during the first few seconds) or give you a ratio, something like 0/67, 1/67/ 14/66, and so on.
Can Malware be removed?
Can, here we attached the link to follow:
Conclusion
All the affected devices start from Malware before it will transform into trojan etc. Thus keep your device up-to-date and with the latest patch.
