Insecure Deserialization Audit (offensive-deserialization)

Authorization & Scope Notice: This skill is part of the REA_Skill + claude-red Unified Security & Reverse Engineering Suite. It is designed strictly for authorized security assessments, defensive architecture reviews, vulnerability triage, bug bounty verification, and remediation engineering on software, infrastructure, and assets you own or have explicit permission to test.

Overview

Insecure deserialization analysis across Java (ObjectInputStream, Jackson, XStream), .NET (BinaryFormatter, Json.NET TypeNameHandling), PHP (unserialize, Phar), Python (pickle, PyYAML), and Node.js, focusing on gadget chain reachability and safe schema-validated data formats. Use when auditing serialized state or message queues.
