What are two ways that Threat Grid can identify unknown malware? $($Choose two.$)$

by recognizing artifacts, which are snippets, or subroutines, of code that exhibit malicious or undesired behavior

by submitting a request to the Global Information Malware Protection Information Base, which is an open$-$source threat database of malicious code

by comparing multiple samples of unknown submissions to known$-$good code samples provided by Talos and other crowdsourcing databases, and alarming on any discrepancies in the unknown submissions

by injecting samples into a sandbox environment, artificially interacting with the operating system in the sandbox, and using machine learning to detect malicious or undesired behavior
