What Are Malware’s ? All You Need To Know About Malware’s.
Malware is the collective name for a number of malicious software variants, including viruses, ransomware and spyware. Shorthand for malicious software, malware typically consists of code developed by cyberattackers, designed to cause extensive damage to data and systems or to gain unauthorized access to a network. Malware is typically delivered in the form of a link or file over email and requires the user to click on the link or open the file to execute the malware.
Malware has actually been a threat to individuals and organizations since the early 1970s when the Creeper virus first appeared. Since then, the world has been under attack from hundreds of thousands of different malware variants, all with the intent of causing the most disruption and damage as possible.
Malware delivers its payload in a number of different ways. From demanding a ransom to stealing sensitive personal data, cybercriminals are becoming more and more sophisticated in their methods.
Why do cybercriminals use malware?
Malware encompasses all types of malicious software, including viruses, and cybercriminals use it for many reasons, such as:
* Tricking a victim into providing personal data for identity theft
* Stealing consumer credit card data or other financial data
* Assuming control of multiple computers to launch denial-of-service attacks against other networks
* Infecting computers and using them to mine bitcoin or other cryptocurrencies.
How Does Malware Spread?
Each type of malware has its own unique way of causing havoc, and most rely on user action of some kind. Some strains are delivered over email via a link or executable file. Others are delivered via instant messaging or social media. Even mobile phones are vulnerable to attack. It is essential that organizations are aware of all vulnerabilities so they can lay down an effective line of defense.
Unfortunately are a lot of malwares XD,
A virus usually comes as an attachment in an email that holds a virus payload, or the part of the malware that performs the malicious action. Once the victim opens the file, the device is infected.
One of the most profitable, and therefore one of the most popular, types of malware amongst cybercriminals is ransomware. This malware installs itself onto a victim’s machine, encrypts their files, and then turns around and demands a ransom (usually in Bitcoin) to return that data to the user.
Cybercriminals scare us into thinking that our computers or smartphones have become infected to convince victims to purchase a fake application. In a typical scareware scam, you might see an alarming message while browsing the Web that says “Warning: Your computer is infected!” or “You have a virus!” Cybercriminals use these programs and unethical advertising practices to frighten users into purchasing rogue applications.
Worms have the ability to copy themselves from machine to machine, usually by exploiting some sort of security weakness in a software or operating system and don’t require user interaction to function.
Spyware is a program installed on your computer, usually without your explicit knowledge, that captures and transmits personal information or Internet browsing habits and details to its user. Spyware enables its users to monitor all forms of communications on the targeted device. Spyware is often used by law enforcement, government agencies and information security organizations to test and monitor communications in a sensitive environment or in an investigation. But spyware is also available to consumers, allowing purchasers to spy on their spouse, children and employees.
Trojans masquerade as harmless applications, tricking users into downloading and using them. Once up and running, they then can steal personal data, crash a device, spy on activities or even launch an attack.
Adware programs push unwanted advertisements at users and typically display blinking advertisements or pop-up windows when you perform a certain action. Adware programs are often installed in exchange for another service, such as the right to use a program without paying for it.
Fileless malware is a type of malicious software that uses legitimate programs to infect a computer. Fileless malware registry attacks leave no malware files to scan and no malicious processes to detect. It does not rely on files and leaves no footprint, making it challenging to detect and remove.
Botnets are networks of infected computers that are made to work together under the control of an attacker.
How Attackers Proceed The Whole Malware Attack On A Victim
It is very important that the people should understand the basic techniques used by attackers to exploit the victims.
* Planning: This stage involves selecting a target and researching the target’s infrastructure to determine how the malware will be introduced, the communication methods used while the attack is in progress, and how/where the data will be extracted. In advanced malware attacks, this stage typically includes the planning of targeted social engineering attacks (such as spear phishing) for initial malware introduction.
* Malware introduction: In this stage, malware is delivered to its target(s) for initial infection. Malware is commonly delivered via social engineering attacks or via drive-by attacks online.
* Command & control: Advanced malware needs to communicate with the attackers to send discovered information and receive additional instructions. It will send user, network, and machine information to the attackers and receive new instructions on what identities or machines to infect next, how to identify the targets, and instructions for data exfiltration.
* Expansion: Attackers will explore the network and spread malware laterally seeking to infect machine(s) or system(s) that have access to the targeted data. Advanced malware often has robust self-propagation capabilities to identify and infect targets quickly.
* Target identification: Once the attacker has gained an initial foothold and explored the network, the target(s) will be identified for the final phase of malware propagation. In this stage the malware is spread to infect machines or systems that contain or have access to the targeted data.
* Attack Event/Exfiltration: The malware payload is executed; in an attack focused on data theft, this is the stage in which targeted data is compiled and offloaded to a location controlled by the attacker. Advanced malware employs techniques to hide exfiltration and other activity, such as encryption or compression of files using crypter and packer tools.
* Retreat: After an advanced malware attack is complete, the malware will often retreat and hide within a computer network or destroy itself, depending on the target organization and likelihood of discovery by security systems.
How to protect against malware ?
When it comes to malware, prevention is better than a cure. Fortunately, there are some common sense, easy behaviors that minimize your chances of running into any nasty software.
* Don’t trust strangers online! “Social engineering”, which can include strange emails, abrupt alerts, fake profiles, and curiosity-tickling offers, are the #1 method of delivering malware. If you don’t know exactly what it is, don’t click on it.
* Double-check your downloads! From pirating sites to official storefronts, malware is often lurking just around the corner. So before downloading, always double-check that the provider is trustworthy by carefully reading reviews and comments.
* Get an ad-blocker! Malvertising — where hackers use infected banners or pop-up ads to infect your device — is on the rise. You can’t know which ads are bad: so it’s safer to just block them all with a reliable ad-blocker.
* Careful where you browse! Malware can be found anywhere, but it’s most common in websites with poor backend security, like small, local websites. If you stick to large, reputable sites, you severely reduce your risk of encountering malware.
Certain strains of malware are easier to detect than others. Some, like ransomware and adware, make their presence known immediately, either by encrypting your files or by streaming endless ads at you. Others, like Trojans and spyware, go out of their way to hide from you as long as possible, meaning they could be on your system a long time before you realize that they’re present. And then there are others, like viruses and worms, that might operate in secret for a time, before the symptoms of their infection start to appear, such as freezing, deleted or replaced files, sudden shutdowns, or a hyperactive processor.
The only surefire way to detect all malware before it infects your PC, Mac, or mobile is to install anti-malware software, which will come packaged with detection tools and scans that can catch malware currently on your device, as well as block malware trying to infect it.
PCs aren’t the only devices that get malware: any device that can connect to the internet is at risk, and that includes your Android phone. While you might not hear about them as much, Android attacks are on the rise, with phishing websites, fake apps, and unofficial app stores being the main distributors of dangerous software.
Android malware, much like PC malware, can do any number of things and cause all kinds of damage. There are viruses, ransomware, botnets, and trojans, spyware, and more: just what you’d expect in this era of smart devices!
Fortunately, if a device can be attacked, it can also be secured, and Android phones are no exception. Just install a anti-virus and its would give a additional security.
Macs have a reputation for being virus-proof, and while that was never true, it was true that, for a long time, the amount of malware that could infect a Mac was laughably small. But while the number of threats for Mac are still small when compared to the enormous malware library that attacks PCs, it’s no longer small enough to ignore. There’s a very real threat your Mac could become infected if you’re not careful and if it’s not secured with a powerful, trustworthy antivirus.
That’s why we recommend you download a antivirus for Mac to ensure your favorite Apple laptop or desktop isn’t compromised by any malware threats that may be lurking on the web.
