As organizations expand so does their attack surface, protecting a wider range of operating systems across various devices and infrastructures is getting more important. This expansion inevitably increases their attack surface, making them more vulnerable to cyber threats. Historically, many businesses have relied on security solutions that primarily focus on Windows environments, but this approach is not sufficient anymore. In today’s diverse and increasingly interconnected digital landscape, a comprehensive cybersecurity strategy must include a sandbox solution that supports multiple operating systems—Windows, Linux, MacOS, and Android.

Threat Landscape Across Operating Systems

Attackers are continuously adapting different platforms and developing new methods to exploit vulnerabilities across them. Emerging technologies, such as edge computing, IoT, and new mobile platforms with the rise of Linux, MacOS, and Android that are introducing additional layers of complexity. Therefore, new attack vectors are being created leading to an increase in malware, designed specifically for these operating systems. 

It is important to have a solution that can adapt itself to the future threats, unlike the traditional sandbox solutions that still focus only on Windows environments. These traditional solutions leave significant gaps in an organization’s defenses since malware designed to exploit Linux servers, MacOS devices, or Android smartphones can go undetected, leading to severe breaches that could compromise an entire network.

The answer is Multi-OS sandbox solutions, enabling organizations to gain a holistic view of their threat landscape, ensuring that potential attack vectors are monitored and secured.

We gathered examples of malware types targeting different operating systems, highlighting the necessity of having a sandbox solution that can detect and analyze threats across multiple operating systems, ensuring comprehensive protection for organizations.

Mettle is typically deployed through vulnerabilities or social engineering attacks, giving attackers extensive control over the infected device.

KINS

It is a banking Trojan designed to steal sensitive financial information, such as login credentials and online banking data, from infected systems. Once it infiltrates a machine, KINS operates by intercepting browser activities, capturing keystrokes, and manipulating web pages to steal user information. KINS is usually spread through phishing emails or malicious downloads and is specifically designed to target financial institutions and their customers. Its primary goal is to enable financial fraud by gaining access to bank accounts and transferring funds without the victim’s knowledge.

Xbash

It is another Linux-focused malware which combines ransomware, cryptocurrency mining, and botnet capabilities, making it a versatile and dangerous threat.

HiddenWasp

A stealthy Linux malware used for remote control and espionage. It could operate undetected, leading to a significant financial and reputational damage.

Mozi

As more organizations adopt IoT devices running on Linux-based firmware, the risk of malware like Mozi, a botnet that targets IoT devices, becomes more pronounced. 

MacOS

Despite common belief that MacOS is a safer option, it can still be vulnerable to malware similar to the other operating systems. 

Atomic Stealer

It is a type of malicious software (malware) designed to steal sensitive information from an infected device. It typically targets login credentials, browser data, cookies, and other personal information stored on a computer. Once AmosStealer infects a system, it can quietly collect this data and send it back to the attacker without the victim's knowledge.

Shlayer

This malware has been one of the most widespread threats on MacOS, primarily distributed through fake Adobe Flash updates, underscoring the importance of vigilant software practices on this platform.

ThiefQuest

It is a ransomware that locks your files and also steals your information. It often disguises itself as a legitimate app or software update that users might download and get themselves infected.

Adwind RAT

It is typically spread through phishing emails with malicious attachments or links. It’s often disguised as legitimate software, tricking users into downloading and running it. Once a system is compromised, attackers can use it for espionage, data theft, or further exploitation of the compromised network.

Filecoder

It is a type of ransomware designed to encrypt a victim’s files and demand a ransom in exchange for a decryption key. Once it infects a system, Filecoder scans for important files, encrypts them, and makes them inaccessible to the user. The victim is then presented with a ransom note, typically demanding payment in cryptocurrency, to regain access to their files.

Macma

It is a macOS malware used for cyber-espionage. Once it infects a system, it can perform various malicious actions, such as stealing sensitive data, logging keystrokes, and taking screenshots. Macma typically targets specific individuals or organizations, often spread through spear-phishing attacks or malicious downloads. It allows attackers to monitor and control the victim’s device remotely, posing a significant threat to data security.

HiddenLotus

It is a malware variant that targets Windows users and is often associated with espionage campaigns. HiddenLotus is spread via phishing emails or malicious document attachments. Once opened, it exploits vulnerabilities to install itself on the victim's system. After infection, it can steal sensitive data, monitor activities, and send the collected information back to the attackers. It has been linked to politically motivated cyberattacks, especially in regions where government surveillance or espionage is a concern.

XLoader
