Abstract

According to examples, an apparatus may include a processor and a memory on which is stored machine-readable instructions that may cause the processor to determine a code fingerprint of a document containing a macro, in which the code fingerprint corresponds to a functionality of the macro. The processor may also determine whether the code fingerprint of the document matches a cluster code fingerprint associated with a cluster of documents. Based on a determination that the code fingerprint matches the cluster code fingerprint associated with the cluster of documents, the processor may determine whether the cluster of documents has been identified as being malicious or benign. In addition, based on a determination that the cluster of documents has been identified as being malicious or benign, the processor may handle the document as being malicious or benign while preventing the document from being sent to a sandbox environment for detonation of the document.
