Abstract
Aspects of the invention include techniques for correlating distinct phishing campaigns by identifying shared modus operandi. A non-limiting example method includes building, from a source code, an abstract syntax tree and building, from the abstract syntax tree, a decloaked abstract syntax tree. The method includes removing payload data from the decloaked abstract syntax tree to define an obfuscation pattern. The obfuscation pattern is compared to a plurality of predetermined obfuscation patterns. The method includes correlating, based on the comparison, the source code to one or more phishing kits.
