So, what, exactly, is Malware?

So, what, exactly, is Malware?

Listen to the news? Read the internet? You know cyber crime is a very big business. Hackers and criminals are out there doing all sorts of nefarious things. Most generally, you hear that malware is some kind of virus that attacks your software programs, infects your hardware, and bungles up your network. But there are many different types of malware, just as there are many types of criminals–each with their own MO and bad intentions. In this e-guide, we will run through some of the major categories of malware, and then suggest 7 different ways you can work to protect your business from malware.

Malware defined - Malware is a generic term that covers all manner of software that is designed to attack your devices, applications, programs, and networks. It is software that has bad intentions. Malicious + Software= Malware. Hackers and criminals create malware for an array of reasons. Some may create it just to attack massive amounts of machines just to show that they can disrupt the cybersphere. Other malware may be created for political reasons. The major reason criminals create malware? To make money without earning it. Yes, stealing. Either by directly pulling money out of accounts, or improperly acquiring data that ultimately provides access to funds. Example: Stealing your SSN and setting up a credit card to use that info, or convincing you to provide the password to your checking account. Others will snatch your organization's data and hold it for ransom. As usual, it is all about money.

FUN FACT: Before the internet, passing around malware to infect a PC meant a criminal had to find a way to infect a floppy disc and trick users into inserting it into their computer. One of the first was created by a high schooler in the early 80’s. It was relatively benign and just created a pop-up with a Seuss-like poem

"The program with a personality
It will get on all your disks
It will infiltrate your chips
Yes it's Cloner!
It will stick to you like glue
It will modify RAM too
Send in the Cloner!"




Unfortunately, most viruses now have far more nasty intentions, and the internet has made it much easier for criminals to break in. No waiting for you to insert a disc drive to steal your data, disrupt your internal business operation, or take down your website. One bad click and you're in trouble.

Malware is a general term and there are several types.

VIRUS - Like the pathogen we associate with human disease, a virus is a “piece of code that is capable of copying itself and typically has a detrimental effect, such as corrupting the system or destroying data.” Source: https://languages.oup.com/google-dictionary-en/.

A characteristic of a virus is that it requires the user to take some action for it to infect your hardware, software, network, etc. For example, inserting an infected thumb drive or clicking on a link found in an email.


ADWARE -Adware is less a type of malware than a symptom created by the infection. Adware invades and then drives the user crazy with endless pop-up advertisements.



WORMS - Similar to viruses, worms replicate and attempt to cause damage but they don’t require a user action. Worms find vulnerabilities or holes in code that allows them access.

TROJAN HORSE - Yes, named after the Greek myth, Trojans trick you into accepting something you want, but inside it has bad intentions. A trojan refers to the method the cybercriminal uses to get you to download a virus or other infected program, rather than the nature of the specific virus.

KEYLOGGERS - This is malware that can track your keystrokes. This particular malware’s goal is to track your keystrokes and identify passwords or credit card information, and then log into your accounts.

RANSOMWARE - If there was any malware that gets more media attention, we aren't aware of it. And it deserves everyone’s attention. Unlike some other forms of malware, once this has invaded, there is very little you can do to eliminate the virus. Ransomware sneaks in, snatches your data and holds it for ransom. Unless you choose to pay the ransom fee, usually in some cryptocurrency, you are out of luck. In the specific case of ransomware, prevention is the key. Having clean backups of your data which are kept continuously up to date is about the only way to sidestep a ransomware attack on your data.

Ransomware vs other malware attacks

Ransomware vs. other malware attacks There is no end to the volume and type of malware out there in cyberspace. For a very long time, organizations were aware that viruses could attack their data, render it corrupted and unusable. They were also aware that malware was used to steal data and use it for–primarily–monetary gain. Sell off banks of credit card numbers, steal identities, re-sell Social Security numbers, etc. Phishing, as we talked about in an earlier blog, is a set of tricks to get access to personal information and probably even to your IT network by stealing access credentials, but that’s not the only way. Cybercriminals also deploy various malware such as viruses, worms and trojan horses to attack IT networks. These malware usually gain entry into the system disguised as genuine email attachments, links to file downloads, etc. and then corrupt the data. If it is a case of a virus whose sole intent is criminal mischief, your surest protection are consistent and frequen...

Everyone wants to go phishing

Everyone wants to go phishing. You are very much aware that your company or organization is at risk, every minute of the day, from cyberattacks, malware, ransomware, and even benign errors that can put your data at risk. Even a failed backup procedure could mean a loss of critical company and customer data. In today’s blog we’re just going to review one of the most common methods that bad actors use to try to gain access to your data. Phishing. Phishing isn’t a particular type of malware or virus that attacks your data. Instead, it refers to the tools cyber criminals use to get access to your data. Phishing refers generally to the bag of tricks they use to break into your house. In phishing attacks, cybercriminals generally send a web link that is disguised to look genuine, and prompt the receiver to share information that will then be misused. For example, an email may be sent to you that looks as though it came from your bank or the IRS announcing a tax refund that your business ...

Your business runs on data, but so do the cyber criminals

Your business runs on data, but so do the cyber criminals who want to steal yours One very painful truth about running a business is that you possess data that is attractive to criminals. There is no avoiding that reality. You have data. They want data. It is an ongoing challenge to maintain data security as cyber criminals' efforts evolve and change on a daily basis. The wall that kept you safe last week may have holes in them today. Keeping up with the latest threats is a specialized field that in-house IT support likely doesn't have. An MSP can provide the support you need in the face of ransomware threats and other malware. Also, an MSP can provide 24/7 monitoring. Speaking of data security, brand damage isn't the only issue with data security breaches. In many cases, there are data protection laws that regulate how you secure personal information. In specific industries there are federal, state, and even overseas regulations that set standards for data protectio...
