Businesses of all sizes are incredibly susceptible to malware and security risks. The term malware encompasses malicious software intentionally designed to harm or exploit a computer network or device. It is important to have an understanding of the common types of malware that attackers use to target businesses.

Ransomware

Chances are you have heard of ransomware – it is the most infamous type of malware. Ransomware locks down and encrypts a business’ files. The attacker then demands that the company pay a ransom to restore access to their data once payment is received. Ransomware has evolved, with attackers typically accessing the network first, locking down all devices and wiping backups before the attack.

Keyloggers

A keylogger is a malicious program that secretly monitors and logs keystrokes. Attackers use keyloggers to steal passwords and other sensitive information that the user types in when using the device.

Remote access trojans

Remote access trojans allow attackers to access and control a computer without the user’s knowledge. They are usually downloaded through email attachments or visiting untrusted websites. Remote access trojans are incredibly challenging to detect, with attackers acting cautiously to not give themselves away.

Banking trojans

Banking trojans use a variety of techniques to steal credentials and money. They typically work by compromising the system to create a backdoor, allowing the attacker to steal data and collect key logs to gain access to bank accounts or conduct identity theft. There is also an increasing use of web form injection, where the malware adds extra fields to forms in the web browser, hoping that the user will enter this additional data.

RAM scrapers

Random access memory (RAM) is the computer system’s short-term data storage, storing information that your computer is actively using for quick access. RAM scrapers work by stealing sensitive information straight from the RAM. Attackers often use this malware on point-of-sale devices to steal debit and credit card information.

Malware is one of the most common tools used to target Australian businesses. Businesses need to establish robust security practices, utilising technology and building awareness. For help keeping your business secure in an ever-changing landscape, talk to the team at onPlatinum today.
