Secure The malicious sample is isolated from the analysis module via a V8 sandbox which doesn't expose system APIs to the malicious sample, which is further hardened to prevent escaping. Most importantly, every analysis should be run in a Docker container with limited host filesystem access, meaning that an attack on box-js can only compromise one analysis, not the entire system. Profiler Profiler follows the static schema to detect web malware. It combines static features analysis of HTML and JavaScript code, including unified resource locator (URL)s. Then it uses machine learning techniques to teach a classifier that decides if a webpage embeds malicious content or not. Suspicious webpages are not processed by this tool.
