In our increasingly digital environment, malware is a cyber threat. What does this frightening word mean? In a world where dangerous software is everywhere, understanding malware is essential for website security. Hackers always try to break into weak systems, from malware to ransomware, and cause havoc. You can defend your online presence from these sneaky attacks with awareness and pre-emptive actions. We’ll explain malware and discuss seven ways to guard your website from these digital predators.
Malware—what is it?
Malware is harmful computer code or software that is meant to hurt or get into computer systems. Malware comes in many forms, and each one affects and bugs devices in its own unique way. However, all malware is created to break computer systems’ security and privacy.
Bad types of malwares steal financial and other private data and use it to blackmail, commit scams, and steal people’s identities. You can get malware on more than just Windows PCs. You can also get malware on Macs and mobile devices.
What is malware?
Malware is a broad term for any kind of “malicious software” that is meant to get into your device without your knowledge, damage or upset your system, or steal your data. Malware includes ransomware, spyware, viruses, botnets, trojans, worms, and rootkits.
Malware is just a bug, then.
Is it a pathogen or malware? Both yes and no. Not all kinds of malware are viruses, but all viruses are malware. In everyday speech, many people use viruses and malware as if they were the same thing. But in the technical world, they are not. Here’s how to think about it: Malware is code that does harm. A virus is only one kind of malware. To be more specific, computer viruses are pieces of bad code that can infect computers and networks.
How does malware do its job?
Malware of all kinds infects your computer or other device when you mistakenly download or install harmful software. This usually happens when you click on an infected link or visit an infected website.
The majority of malware attacks happen when you do something by accident that causes the malware to be downloaded. This could mean clicking on a link in an email that is infected or going to a website that is harmful. Sometimes hackers use peer-to-peer file-sharing services and free software download packages to get malware out to people. Adding harmful computer code to a popular file or download is a good way to get a lot of people to use malware. Text messages can also spread viruses on mobile phones.
Putting malware on the software of a USB stick or flash drive is another way to do it. Then, when the USB stick is linked to another device, the malware is likely to not be found because it is stored on the device’s hardware instead of its memory. That’s one reason why you should never plug in a USB drive that you don’t know into your computer. Once the malware is installed, it starts to work for the hackers by infecting your device.
The most common types of malwares
The following groups of malwares make up most of the malware:
Ransomware
Ransomware is like a kidnapper’s demand note, but it’s bad software. Ransomware locks your device or files and won’t let you access them until you pay the hacker a fee. Anybody or any group that keeps important data on their devices is vulnerable to viruses.
Spyware
Spyware listens in on a device or network and sends information about it to an attacker. Hackers often use spyware like Pegasus to watch what people do on the internet and collect personal data that can be used to steal someone’s identity, like login credentials, credit card numbers, or bank information.
Worms
Worms are made with one goal in mind: to spread. When a worm gets into a computer, it copies itself and spreads to other devices, staying active on all of the computers it has already attacked. Some worms are used to load other malware onto your computer. Other kinds of worms are only meant to spread and not hurt the computers that they live on, but they still use a lot of data and slow down networks.
Adware
Adware is used to make money for the person who made the malware by showing annoying ads over and over again on a device that has it. Adware often comes in the form of free games or computer toolbars. These kinds of adware get personal information from people who get them and then use that information to make the ads they show more relevant to them. Adware is just as annoying as other kinds of malware, even though most of it is installed legally.
Trojans
A Trojan is a type of malware that hides another type. Trojan malware gets into a person’s computer by pretending to be safe software. The trojan starts working as soon as it is installed, and it may even download more malware.
Trojan malware gets its name from stories that ancient Greek artists wrote about Athenians hiding in a huge wooden horse and then coming out when the Trojans pulled it inside their city walls.
Botnets
A botnet is not a type of malware but a group of computers or computer code that run malware. Malicious software is attacking a group of computers. These computers are called “bots,” and they follow instructions from a manager.
When computers in a botnet are linked together, they form a network. This gives the manager access to a lot of processing power that can be used to plan DDoS attacks, send spam, steal data, and make fake ads on your browser.
7 tips to guard your computers against malware
- Developing security policies
Security rules tell workers what to do, when to do it, and who can access systems or information. For compliance, rules, or laws, you also need policies.
Here are some examples of security rules that might help prevent malware attacks:
Social Engineering Knowledge Policy: This policy sets out rules for raising knowledge about the dangers of social engineering and how to deal with such threats.
Server Malware Protection Policy: This policy tells you which server systems need to have anti-virus and/or anti-spyware programs installed.
Policy for Installing Software: The Software Installation Policy is meant to spell out the rules for installing software on work computers. To lower the chances of losing program functionality, putting private information on the company’s computer network at risk, getting malware, and getting in trouble with the law for using illegal software.
Removable Media Policy: The Removeable Media Policy’s goal is to lower the chances of losing or sharing private company data and getting malware on computers used by the company.
- Putting in place training for security awareness
Security awareness training is an investment in your company’s safety as a whole. Saving a lot of money that could be lost to cyberattacks could be possible with this training.
Setting up a baseline, training users, running phishing ads, and reporting results are all parts of awareness training.
Baseline Testing: Run baseline tests to determine the possibility of a user falling victim to a phishing attack.
User Training: This includes interactive modules, videos, games, posters, and emails that are meant to teach users about the newest social engineering attacks. Email alerts are often set up to automatically do this training.
Phishing Campaigns: Run fully automated, simulated phishing attacks on behalf of your company.
Reporting Results: numbers and pictures for scams and training to show the return on investment.
The best way to raise security knowledge is to make it a part of the security training that new employees have to go through before they can access important systems.
Employees should be trained at least once a year to spot attacks, react properly to them, and report them to the incident response team so that they can take action.
- Employing Multi-Factor Authentication Through Apps
Microsoft claims that multi-factor authentication (MFA) can stop 99.9% of automated malware attacks on Windows computers.
Three nines of protection are a good number, but the word that matters here is “automated.” MFA is just one layer of protection, as with everything else in security.
Threat players who are very good at what they do use more than automated attacks to penetrate a network.
Also, it’s important to note that SMS-based MFA is easy to circumvent since passcodes are sent in plain text. This lets bad guys get the PIN, access your account, and then send the code to your phone without your knowledge.
- Putting in spam and anti-malware filters
Emails are the main way that malware and socially engineered threats get spread.
Even though workers already have antivirus and malware software on their computers, adding them to your mail servers is still a good idea as part of a “defence in depth” strategy.
It’s hard to know how to set up a spam screen. On the one hand, the person in charge of the network wants to stop all bad data.
A too-strict filter, on the other hand, will block valid traffic, which will make end users unhappy.
- Changing the default settings for an operating system
Although the default choices are a good way to protect your computer, they can be improved.
The network administrator is eventually in charge of making sure that the domain, workstations, and devices are set up to follow the company’s security rules.
- Do regular assessments of vulnerabilities
Network vulnerability scans should be conducted regularly to find known holes, missing security controls, and common setup mistakes.
This gives people in charge of a network a lot of information about which hosts are running which services.
Most scanners display the data they have collected in a dashboard that details each flaw they have discovered and how serious it is.
- Use antivirus and malware programs that you know you can trust.
Many people don’t use computers, phones, or tablets without security and malware protection. A study from the Digital Journal shows that in 2017, only 27% of Windows computers were not protected. However, not all of those people use a reputable or well-known service.
Buying good antivirus software is a small price compared to the damage that could be done to your devices by hacking or crypto jacking.
