What Is Malware? And How To Prevent An Attack.
What is Malware?
We have all heard the word ‘Malware’ but what is it, and how can it affect you?
Malware is essentially Malicious Software (Malicious Software). Malware is a term to describe viruses, trojans and worms. The software is secretly designed to install itself on users systems. Nearly one-third of the world’s computers have been affected by malware, this is a figure which continues to grow rapidly as we rely more on computers, phones and technology.
How does malware spread?
Each piece of malware is different, although most malware will require some form of user interaction. Some forms are delivered via email, or simply ‘pop’ onto your screen when you visit an unsafe website. Some forms of malware can be delivered via text message, or even on social media sites. Malware, although less likely, can be spread to mobile phones. It's essential to be aware of all vulnerabilities so that you can prepare effectively.
Phishing emails are one of the most effective approaches to sending malware to the majority. The most common Phishing attack consists of emails being sent to individuals pretending to be from a known brand or company. Whether this be a fake email from PayPal, Office 365, Apple, etc, they typically send you to a fake login page requesting your username and password. There are other, more advanced Phishing attacks which sends malware to the victims machine - often as an attachment. These attacks rely on the victim opening the malicious attachment which essentially triggers the malware hidden inside the attachment itself.
Hackers are able to create near perfect fraudulent emails from legitimate companies to trick victims into thinking they are ‘real’. By clicking the link, you are allowing the malware onto your computer without even realizing.
Ransomware is a type of malware that threatens deny access to the user’s data, or block accounts until a ransom is paid. Infected computers may show messages claiming to be from the police, claiming you have committed illegal activity and must pay a fine
A good example of this is Magecart. A malware that has been reported to have already affected 17,000 websites and counting…
