Common types of adware include free games or browser toolbars. AdwareĪdware’s job is to create revenue for the developer by subjecting the victim to unwanted advertisements. Other types are designed only to spread, without intentionally causing harm to their host machines – but these still clog up networks with bandwidth demands.
Some worms act as delivery agents to install additional malware. A worm infects a computer, then replicates itself, spreading to additional devices while remaining active on all infected machines. Worms are designed with one goal in mind: proliferation. Hackers typically use spyware to monitor a person’s internet activity and harvest personal data, including login credentials, credit card numbers or financial information, for the purposes of fraud or identity theft. Spyware collects information about a device or network, then relays this data back to the attacker. Any individuals or groups storing critical information on their devices are at risk from the threat of ransomware. It typically works by locking or denying access to your device and your files until you pay a ransom to the hacker. Ransomware is the malware version of a kidnapper’s ransom note. The vast majority of malware falls into the following basic categories, depending on how it functions: Ransomware So how does malware work? What is a malware attack? Let’s find out. What separates the various types of malware from each other is how they go about doing this. Once the malware has been installed, it infects your device and begins working towards the hackers’ goals. This is why you should never insert an unfamiliar USB drive into your computer. Because the malware is loaded onto the device’s internal hardware (rather than its file storage), your device is unlikely to detect the malware. Mobile devices can also be infected via text messages.Īnother technique is to load malware into the firmware of a USB stick or flash drive.
Embedding a bit of malware in a popular torrent or download is an effective way to spread it across a wide user base.
In other cases, hackers spread malware through peer-to-peer file sharing services and free software download bundles. This action might be clicking a link in an email, or visiting a malicious website.
Most malware infections occur when you inadvertently perform an action that causes the malware to be downloaded. No matter the type, all malware follows the same basic pattern: The user unwittingly downloads or installs the malware, which infects the device.
Computer viruses are malicious code that spreads across computers and networks How does malware work? Think about it this way: Malware is malicious code. You’ll hear a lot of people using the two terms interchangeably, but from a technical point of view, viruses and malware are not the same thing. While all computer viruses are malware, not all malware are viruses.
And it’s important to note that malware isn’t just a threat to your PC – Macs and mobile devices can also be targeted.
