Over time malware might have decreased worldwide, but malware types continue to evolve. Some of them have become hybrids of one another. Let's learn about the common types of malware:
Among the most common type of malware, computer virus are similar to human virus. Like a bodily virus, it also requires a host, meaning a device, to live once the user downloads an infected file, the virus gets triggered and starts replicating to spread from one system to another.
Worm malware is similar to malware virus, but they don’t need a device to replicate. Worms can copy themselves and can transmit by exploiting software vulnerabilities. Moreover, worms silently work and infect the device or entire network once installed.
Trojan or Trojan horse is a malware that disguises as legitimate software, application and tricks the user into downloading, thereby taking complete control of the device. Trojans damage the system, steal data, & are often spread via email attachments, downloads, etc.
As the name explains, it is a type of malware that locks down and encrypts the victim’s data or device and then demands a ransom to restore access and decrypt data. Ransomware creates a backdoor, allowing hackers to gain access to devices and saved information.
Botnets act as a spider crawling over the web to look for security vulnerabilities to exploit and hack the system to gain access to data and give cyber criminals remote access to devices. Bots can launch DDoS attacks, record activity, take screenshots, and do more.
Spyware infiltrates the device without the user’s knowledge to track and sell data. It spies on internet activity, tracks digital footprints, captures financial details and credit card information without the user’s knowledge, and uses it for fraud.
Advertisements designed with malicious intent to collect data are Adware malware. They are usually installed in exchange for another service and sell the gathered user information to third parties or leverage it for identity theft.
Fileless Malware is another type of malware that uses built-in software, apps to execute malicious activities. Unlike other malware infections, to download the malware, no files are needed; it is a memory base malware hence is called Fileless malware.
