The states may include labeled states corresponding to the deserialization examples. A state may correspond to a path from a start state to the state. The method may further include while traversing the states, generating a state mapping including, for the state, a tracked subset of the states, determining that the path corresponds to a path type, inferring, using the path type and the state mapping, a regular expression for the state, and determining, for a new deserialization example and using the regular expression, a polarity indicating whether it is safe to deserialize the new deserialization example."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Synthesis of deserialization filters from positive and negative examples","description":"A method for detecting malicious code may include generating, from deserialization examples, a finite automaton including states.
