It’s the 21st century. Businesses are moving online and with terabytes of data.
According to a study, the big four companies Microsoft, Google, Amazon, and Facebook store 1,200 petabytes between them, which is equivalent to 1.2 million terabytes, where one terabyte is 1,000 gigabytes.
The huge amount of data has made cyber attacks an imminent event. And one of the most threatening pathways of a cyber attack is malware.
Malware (malicious software) attacks are on the rise. According to the 2018 Internet Security Threat Report of Symantec, the number of malware variants increased by 54% in 2017.
According to the 2019 Internet Security Threat Report from Symantec, cyber-criminals using malware increased by 25%. This is clearly an area that requires focus from businesses and government. Otherwise, its effects could be devastating.
How Does Malware Impact Cybersecurity?
Malware is a file or program that may harm the computer user, and cause the breach of data security.
Malware includes a variety of types like:
- Command and control
- Trojan horse
What Does Malware Do?
They usually result in a few established outcomes:
1. Data Exfiltration
Malware usually takes control of the computer without user consent. And after taking control, it can filter out essential business data, client data, and even personal data, without any knowledge of the user.
It is essentially a form of data theft, which can be very costly. According to a study by Ponemon, the global average cost of the data breach has risen by 6.4% from 2017 to $3.86 million. Apart from business disruption, this can tarnish the image of the company, and hamper customer goodwill.
2. Operations Disruption
Cyber-security ensures the smooth running of digital operations of a business. But a malware attack can wholly or partially disrupt it. The levels of disruption may vary in scale.
It may range from a virus corrupting crucial Operating System on one system, to disrupting whole networks of systems. One of the best examples of the latter is Stuxnet, a malicious computer worm, capable of bringing down whole networks.
It has larger ramifications, sometimes in the form of DDoS attacks. For example, a DDoS attack can completely shut down your website in less than a minute. And no website is immune to it. For instance, the 2016 Dyn cyber-attack paralyzed PayPal and Twitter.
If proper security measures are not in place, such business disruptions cause an enormous loss in revenue for the down-time.
3. Money Extortion
If the malware finds its way past your cyber-security, one of the reasons could be extortion of money. To this end, Ransomware is particularly important. It basically freezes your access to your date until you pay up a certain demanded amount.
Have a look at these pertinent statistics:

And these types of attacks are evolving. Reveton, one such ransomware, accused their targets of child pornography and other illegal activities and held them to ransom until they paid up.
