Content matching and vulnerability remediation

One or more non-transitory machine-readable storage media storing instructions that are executable by one or more processing devices to perform operations comprising:

• receiving input content through a user interface;
• generating a whole file signature representing an entirety of the input content, the whole file signature being based on a hash of the input content;
• searching a first knowledge base for a file having a whole file signature that matches the generated whole file signature;
• processing the input content to identify a snippet of content in a second knowledge base based on a signature vector corresponding to the input content;
• generating a report based on at least one of the file or the snippet of content;
• and
• displaying the report on a user interface;
• wherein processing the input content comprises:
• generating the signature vector corresponding to the input content, the signature vector being based on a hash of at least part of the input content;
• and
• searching the second knowledge base for the snippet of content based on the signature vector;
• wherein the report shows a hash value corresponding to the file or the snippet of content, but not text from the file or the snippet of content;
• and
• wherein a hash value associated with the whole file signature is used for searching the first knowledge base or a hash value associated with the signature vector is used for searching the second knowledge base.
