A computer-implemented method for malicious content detection and attack prediction in an industrial control system, comprising: receiving a hash query from a secure media exchange node, wherein the hash query comprises a file hash generated at the secure media exchange node based at least in part on one or more files received at the secure media exchange node; querying a cyberattack case studies information database based on the hash query to generate one or more attack correlation information items associated with at least one of the one or more files by comparing the hash query with file hashes stored in the cyberattack case studies information database, wherein the cyberattack case studies information database comprises a cyberattack correlation and prediction database configured to store one or more hashes associated with one or more malicious content items, and wherein querying the cyberattack case studies information database comprises: querying the cyberattack correlation and prediction database with the hash query, and receiving one or more predictive indicators, wherein each of the one or more predictive indicators are based on an attack tree mapping associated with the file hash, wherein the attack tree mapping is a data structure that stores associations between a plurality of file hashes comprising a first file hash associated with one or more malicious content items and a second file hash associated with one or more additional malicious content items, wherein the first file hash and the second file hash were historically received in the same hash query, and wherein the file hash generated at the secure media exchange node matches the first file hash; generating a file security analysis regarding the one or more files based on the one or more attack correlation information items which comprise the one or more predictive indicators, wherein the file security analysis comprises (i) an indication of the one or more malicious content items present in the one or more files received at the secure media exchange node, and (ii) an indication of prediction of the one or more additional malicious content items; and outputting the file security analysis to a secure media exchange threat intelligence portal associated with the secure media exchange node for authorization of the one or more files. receiving a hash query from a secure media exchange node, wherein the hash query comprises a file hash generated at the secure media exchange node based at least in part on one or more files received at the secure media exchange node;
