Obfuscated strings hidden behind array accesses or dynamic evaluations are reconstructed by analyzing the code that builds them. When the deobfuscator identifies the pattern, it can substitute the computed result for the original reference.
For a security analyst working on a portable machine (e.g., a forensic laptop), the following workflow is recommended: javascript+deobfuscator+and+unpacker+portable
: If the tool evaluates code dynamically to unpack it, it must do so inside a tightly controlled, isolated sandbox to prevent malicious code from breaking out onto your local machine. Step-by-Step Workflow for Analyzing Code Portably Obfuscated strings hidden behind array accesses or dynamic
