In an embodiment, a method comprises receiving, at a computer device, a file containing instructions in a programming language; based on a syntax of the programming language, parsing the file to generate parsed information, and based on the parsed information, generating a syntax tree for the file; identifying one or more alphanumeric strings in the syntax tree, and based on the alphanumeric strings, generating a syntax string for the syntax tree; generating a hash digest by applying a piecewise hashing to the alphanumeric strings in the syntax string; determining whether the hash digest indicates that the file contains potentially malicious code; in response to determining that the hash digest indicates that the file contains the potentially malicious code, performing a responsive action."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting malicious program code using similarity of hashed parsed trees","description":"Techniques are described herein for detecting malicious program code stored on computer devices before the code can be executed to potentially compromise a computer network.
