Best online Sandbox to analyse a malware
A system is like a human; it can get infected and it needs to be isolated to analyze to avoid infecting others systems.
Imagine a person infected with a virus that can contaminate others; to avoid any contamination, we need to isolate him or her so that we and consult to find out the root cause and provide a preventive measure so that the virus won’t infect others people.
A malware infected a system behaves the same way. to protect others system, we need to isolate it and analyze it to find the root cause and provide a preventive solution so we can detect such malware in the future.
So, what is a malware?
A malware is any executable file, application, process or sub process or any binary file that after running on a system will behave inappropriate to steal credential, have a persistency method, command and control method, privilege escalation and so on.
To understand that an executable file, an application, a process or any binary is a malware, we need to analyze it in a secure environment to not spread it or compromise our production environment.
In the past we used to configure our own Sandbox to analyze a malware, but nowadays, we do not need it anymore, we have many online Sandbox solution with all the features needed to do that for us.
Let’s share the tools with you.
A multi‑engine malware and URL scanning platform, now part of Google’s Chronicle since 2018. It aggregates over 70+ antivirus engines, URL scanners, and threat intelligence sources, allowing users to upload files or submit URLs for analysis. You can submit via the web interface, desktop tools, browser extensions, email, or API. Free users have limits, while premium tiers unlock enhanced features.
A versatile malware and phishing analysis solution that supports both cloud-based and on-premise deployment. It enables deep static, dynamic, and hybrid analysis of malicious files and URLs across multiple operating systems such as Windows, macOS, Linux, Android, and even iOS.
A free, community-driven malware sandbox powered by Payload Security and Falcon Sandbox, integrating multiple detection engines such as static, dynamic, and ML to analyze files and URLs for malicious behavior.
An interactive cloud-based malware sandbox. Unlike automated sandboxes, it lets you manually interact with the VM to drive the sample, enabling macros, clicking dialogs while capturing real-time behavior and indicators.
A free online malware analysis service, the tool lets you upload files or submit URLs. It checks them with emulation engines, extracts indicators of compromise (IOCs), examines certificates, and checks for phishing and malicious behaviors.
