Common Types of Malware to Watch Out For

Infected SystemsWhat is a virus and is it the same as malware?

Malware describes software designed to act maliciously on a computer. The name ‘malware’ is a shorthand for ‘malicious software’ and describes exactly what it is. A computer virus is a single type of malware that can cause harm to your PC, but it is only one of many. Other types of malware are listed below.

Adware

Short for advertising-supported software, adware is a type of malware that delivers adverts to your computer. These advertisements often pop-up and are intrusive, irritating and  designed to trick you into clicking something you don’t want. A common example of malware is pop-up ads that appear on many websites and mobile applications.

Adware often comes bundled with “free” versions of software that uses these intrusive advertising to make money. Commonly it is installed without the user’s knowledge and are purposely made to be difficult to remove.

Spyware

Spyware is designed to spy on the user’s activity without their consent or knowledge. Spyware is often installed in the background, collects keyboard input and can harvest data from the computer, monitor web activity and more.

Spyware typically requires installation to the computer. This is commonly done by tricking users into installing the spyware themselves instead of a software application that they thought they were getting. Victims of spyware are often be completely unaware of its presence until the stolen data is used elsewhere (ie in a fraudulent bank transactions or stolen online accounts).

Virus

A computer virus is a form of malware that is installed inadvertently, causing damage to the computer and / or user. A typical virus may install a keylogger to capture passwords, logins and bank information from the keyboard or it might steal or delete data, interrupt programs or cause the computer to crash.

Modern virus programs commonly use your computers processing power and internet bandwidth to perform illegal tasks remotely for hackers. The first sign of this can be when the computer sounds like it is doing a lot of work when no programs are running. A computer virus is often spread through installing unknown software or downloading attachments that contain more than they seem.

Ransomware

Ransomware is a very malicious variety of malware that prevents the user from accessing their own files and data until a ransom is paid. Files within the system are often encrypted with a password that won’t be revealed to the user until they receive money usually in the form of bitcoin.

Instead of accessing the computer as normal, the user is presented with a screen which details the contact and payment information required to access their data again.

Ransomware is typically downloaded through malicious file attachments, email or through a vulnerability in the computer system.

Worm

Another type of malware is the computer worm. Worms spread across computer networks by exploiting vulnerabilities within the operating system. Often these programs harm their host networks by consuming large amounts of network bandwidth, overloading computers and using up all the available resources.

While similar to a virus a worm is able to both copies of itself and spread independently. A virus must rely on human activity to run a program or open a malicious attachment while worms can simply spread over the network without human intervention.

Could Your Backups Survive A Ransomware Attack?

More and more businesses and organizations are getting hit by ransomware demands. It doesn’t matter what industry you are in, hospitals, schools, factories, offices,… are all getting infected and hackers are raking in millions.

Ransomware attacks are devious in their simplicity. A user in a business is tricked into opening a file, usually through a phishing email or download. The file contains malware which then encrypts your data and demands money in exchange for the password to decrypt you data.

All businesses should have a backup and thus should simply be able to restore from their backup if the worst occurs. But this is not always the case.Sometimes the backup  fails for some reason and the data can’t be retrieved. In other instances, the business has a backup that can be restored but it doesn’t include everything they need. So have you tested your backup recently?

Sometime the backup is also caught in the ransomware encryption and becomes useless as a recovery method. This is why it is good to have at least one backup stored offsite and not connected to a computer network.

The only defense is to block the malware before it can infect your network and then continue the protection with a comprehensive backup strategy for all workstations and servers.
