Executive Summary The WANDR benchmark from Perplexity AI puts research agents through a rigorous two-pronged test: Wide retrieval (covering many relevant sources) and Deep retrieval (drilling into a single source’s nuance). We’ll walk through the YAML-based task definitions, the CLI runner, and how to integrate WANDR into your existing evaluation pipelines — no flaky “vibes-based” metrics here. By the end, you’ll have 5 proven, repeatable ways to leverage WANDR for your own agentic search systems, from quick smoke tests to CI/CD-gated accuracy checks. 📎 Read the official WANDR benchmark announcement for the research paper and datasets. I remember the exact moment my team stopped trusting leaderboard scores for our internal RAG agent. It ranked #1 on a popular QA benchmark, yet field engineers kept reporting that the agent missed a key nuance buried in a 14-page specification PDF. Sound familiar? Precision against a curated test set didn’t translate to real-world wide and ...

TL;DR: AI agents are not magic; they fall for the same social engineering that tricks humans. We reverse-engineered seven popular coding and security AI agents and found they can be poisoned through YAML, natural language prompts, and even embedded invisible characters. Evasion techniques include zero-width joiner obfuscation , prompt injection , dependency confusion , and silent deserialization payloads . Defensive snippets and detection rules follow. Mitigation starts with treating AI agent output as untrusted and hard‑coding policy at the scanner layer. Cracking open a pipeline and watching a supposed guardrail AI agent run an attacker’s code is a sobering moment. I’ve seen it happen inside a locked‑down Kubernetes namespace where the only moving parts were the SAST scanner, a secrets‑detection engine, and the code itself. The agent wasn’t stupid – it was just too helpful . That’s the vulnerability. We’ll walk through exactly how seven top AI agents can be tricked i...

TL;DR – Executive Summary Marker converts PDFs to clean Markdown/JSON with layout detection; ideal for RAG pipelines. Docling (IBM) offers high-fidelity table and reading order extraction via YAML config. Unstructured provides a kitchen-sink of partitioners; JSON output with element metadata. PyMuPDF4LLM streams PDF content directly into LLM-ready JSON chunks. Camelot + Tesseract combo dominates tabular data extraction when OCR is needed. LlamaParse leverages LLMs for semantic parsing; returns JSON with detection confidence. GATE + Grobid serve academic/legal documents, outputting TEI XML that is trivially mapped to JSON. We’ve spent the last 18 months ripping apart PDF ingestion pipelines for a petabyte-scale legal document system. Our team tried everything – from regex chaos to heavy‑weight computer vision models. The hard lesson: PDFs are not data; they are chaotic streams of vector‑path garbage. Extracting structured JSON from them is an exercise in controlled fail...

Executive Summary (TL;DR): Cross-Platform Java Vehicle : A single JAR payload that runs unmodified on Windows, Linux, and macOS – making traditional OS-specific endpoint defenses nearly useless. Evasive by Design : Heavy obfuscation, dynamic class loading via the Reflection API , and anti-analysis checks that frustrate sandboxes and static signature scanners. MaaS & Modularity : Low barrier to entry for threat actors; a plugin architecture enables rapid feature deployment without recompiling the base trojan. We reverse-engineered a sample from the QuimaRAT MaaS report and watched it dance through three separate operating systems without breaking a sweat. This isn’t just another commodity RAT—it’s a lesson in Java’s underbelly weaponized for profit. When Java gets slapped in a malware campaign, most defenders roll their eyes and expect a messy JAR wrapped in a dropper. QuimaRAT MaaS changes that game. I’ve spent nights pulling apart the obfuscated class tree, tracing the c...

Executive Summary / TL;DR JadePuffer marks the first documented ransomware campaign where a large language model orchestrated the entire kill chain—from highly personalized phishing to mutating encryption binaries. The attack employed a Kubernetes CronJob manifest to inject a self‑mutating payload that used the OpenAI API to generate encryption routines in real time. Polymorphic behavior and LLM‑driven social engineering made signature‑based detection useless. We walk you through the YAML infection vector, the Python code that called the LLM, and the forensic commands we used to trace it. This is no longer a theoretical risk. JadePuffer proves that LLM ransomware is a battlefield reality. Last week, while digging through an anomalous spike in egress traffic from one of our staging clusters, we found something that rewrote our threat model. A pod labeled log‑cleaner had spun up, pulled a tiny Alpine image, and started an outbound connection to api.openai.com . That alone w...

TL;DR – Technical Takeaways Scaffold splitting trumps random splits for kinase inhibitor models—without it, your QSAR will lie to you. We built a Random Forest model on ChEMBL data, using RDKit descriptors and BRICS fragmentation. SHAP waterfall plots exposed which molecular fragments drive pIC50, linking structure to activity. The pipeline runs as a Kedro‑wrapped co‑scientist inside a container that a chemist can interrogate via a REST endpoint. We’ll share the top 5 predicted EGFR inhibitors our model surfaced—molecules never tested against EGFR in the training set. We’ve been burned before by a “world‑class” QSAR model that hit R² = 0.89 on random cross‑validation, only to crash to R² = 0.21 when we tested it on a new chemical series. The sin? Random splitting. In kinase‑centric projects like EGFR inhibitor discovery, random splits create artificially high performance by leaking close analogs across folds. That’s why we pivoted to a scaffold‑split QSAR method —a ...
