CAPE Sandbox vs ReversingLabs Cloud Sandbox

CAPE Sandbox is an open-source malware analysis tool that runs suspicious files in isolated virtual machines, monitors their behavior, and collects forensic artifacts. It can record execution activity, files created or changed, network traffic in PCAP format, screenshots, and memory dumps. CAPE also performs dynamic malware unpacking, applies YARA classification to unpacked payloads, and extracts malware configurations through static and dynamic analysis.

Documented analysis targets include Windows executables and DLLs, PDFs, Office files, URLs, HTML, scripts, ZIP files, and Java JARs. A debugger can use YARA signatures for custom unpacking and configuration extractors, anti-sandbox countermeasures, and instruction traces. The Django web interface supports submissions, report browsing, and searching results; a REST API and Python functions support automated file and URL analysis. Setup requires host and guest machines, with each analysis run in a fresh virtual machine. GNU/Linux, preferably Ubuntu LTS, is the recommended host, and Windows 10 or Windows 11 23H2 the recommended guest. CAPE is free and self-hosted, and is distributed without warranty.

ReversingLabs Cloud Sandbox executes files in isolated environments to observe runtime behavior and complement static analysis. It offers automatic analysis as well as interactive sessions where analysts can engage with a sample while it runs. Analysis supports Windows, macOS, Linux, and Android; Android is available for file submissions, not URL analysis.

Reports include network and behavioral indicators, process activity, registry and file changes, and downloadable artifacts. Files can be submitted through the Dynamic Analysis Submission API. The feature preview permits five samples per day, while full access is available at additional cost through ReversingLabs Sales Support. Individual samples can be up to 400 MB, and artifacts are available for download for one year. For private samples, other ReversingLabs customers may see results but not sample contents, dropped files, PCAP files, or memory string dumps. VPN routing is used when samples may connect to the internet. The service is intended for security operations teams handling incident response and threat hunting. ReversingLabs is headquartered in Cambridge, Massachusetts, and was founded in 2009.
