Binrev chains common tools to automate reversing of Windows .NET, native, and Java binaries using de4dot, JustDecompile, procyon and more, aiding static code review and hardcoded secret hunting.

Patching Java jars without source: extract classes, edit bytecode directly, verify, and repack — faster and less error-prone than decompiling, and handy for bypassing license or signature checks.

Finding bugs in OWASP WebGoat: decompiling the Java/Spring app, automating account creation in Python, spotting SQL-injection anti-patterns by regex, and building exploits—from a Ya!vaConf talk.
