Automating Disassembly with Local AI Agents

🛠️ This blog demonstrates using AI agents to automate a VB6 disassembler by exposing its parsed model through the Windows Running Object Table and providing an operator briefing plus auto-generated prototypes. The agent (Claude Code in the examples) binds to the COM object, runs scripts to extract P-code, reconstruct source, generate call graphs, and export function metadata to SQLite, all locally without uploading binaries. The approach decouples tool features from fixed menus, enables repeatable exhaustive analysis, and preserves sensitive data on the analyst's workstation.

Typosquatting: Runtime Risks in Third-Party Web Scripts

🛡️ Attackers are embedding AI-generated lookalike domains inside legitimate third-party scripts, transforming typosquatting from a user mistake into a browser-runtime threat that traditional controls miss. Firewalls, WAFs, EDR, and CSPs cannot observe what approved scripts do once executed, enabling silent exfiltration as in the Trust Wallet compromise. Effective detection needs runtime behavioral monitoring that traces script actions, network calls, and deviations from established baselines rather than relying on static vetting.

Making Rust Workers Reliable: Wasm Panic and Abort Recovery

🛠 Cloudflare explains reliability improvements for Rust Workers that prevent panics and aborts from poisoning Wasm instances. They upstreamed fixes into wasm-bindgen, adding panic=unwind support via WebAssembly Exception Handling so Rust destructors run and instances remain reusable after a panic. They also implemented abort classification, an abort recovery hook, and an experimental --reset-state-function to reinitialize libraries without reimporting them. Users are encouraged to upgrade to workers-rs 0.8.0 and try the --panic-unwind flag for improved stability.
