  1. Earliest Known PolinRider Malware Found in 2025 npm Packages

    OpenSourceMalware traces nine itsa-* npm package versions published on 4 May 2025 from a hijacked maintainer account to the PolinRider campaign, eight months before documented victims. It decodes the EtherHiding chain (BNB Smart Chain and Ethereum calldata, JADESNOW, INVISIBLEFERRET bootstrapper, Socket.IO RAT, Python stealer) and links the 2025 sample to 2026 force-push infections. It lists IOCs, hashes, a timeline and hunting guidance.

  2. Show HN: I Turned DOOM into a Transformer

    Doomformer compiles integer neural networks into ZDoom maps that run in ViZDoom. Voodoo dolls do the arithmetic, and sector light levels and plane heights hold the values. Python reads every value back and compares it with a NumPy integer reference at tolerance 0. It runs MNIST (97.16 % on all 10,000 digits, every pass exact), small transformers, a learning perceptron and a SUBLEQ machine. It is about 23,000 times slower than NumPy on a small MLP.

ICA gates sigma with paired-rollout evidence, cutting TIR to 13.8% (frozen) and 11.2% (online) and raising accuracy from 47.5% to 48.7% and 49.3%. It transfers to GSM8K.

  40. Claude reveals ECDSA curve origins

    Anthropic's Frontier Red Team reports that Claude recovered how the NIST P-192/224/256/384/521 and ANSI X9.62 curve seeds were generated. They are outputs of the C library's lrand48 LCG seeded with 1997–98 Unix timestamps, not hashes of a passphrase. The method scanned for weak-PRNG signatures, then used LLL lattice reduction to recover the truncated LCG state and stepped it back to srand48 initialization. Claude also traced some base points to the FreeLIP/NTL random generator. Reproducible Python is included. The authors say this is not an attack and makes deliberate backdoors less plausible. The B-163 seed and the base points of P-224/256/384/521 and the binary curves remain unexplained.

It argues for SCA based on program analysis, with source code as ground truth cross-checked against manifests and the file system. Useful for evaluating SCA tools and understanding SBOM accuracy limits.

  50. BijectiveLabs/trading-research-agents

    Open-source Python CLI (`tra`) for autonomous trading desks in which LLM analysts (technical, macro, on-chain, sentiment) and validators only give opinions on figures the system computed. Fixed rules do the arithmetic: pricing the round-trip cost, applying risk limits, sizing, cost gates, and sending a single order with stop attached via ccxt (Bybit and OKX demo accounts tested). It supports multiple model providers with per-role models, effort settings and fallbacks. Every answer is parsed against a closed schema, every refusal is logged with the figure behind it, and models can tighten but never loosen controls. This makes it a concrete reference for keeping LLM agents away from arithmetic and money.

It reports that under 9.5% of vulnerabilities are reachable at function level, and that combining reachability with EPSS cuts noise by about 98%. It also finds Python phantom dependencies (up to 60% of dependencies and 85% of vulnerabilities for some tenants), 18% of npm OSV entries lacking CVE aliases, 69% of advisories published after the fix release (median 25 days), and 47% of advisories with no code-level info. For Java, 24% of fixes need a major version bump and 95% of upgrades carry breaking changes. Written by a vendor, so the prioritization conclusions favor its product.

    Compares static SCA (manifest/source scanning at build time) with dynamic SCA (runtime instrumentation). Static scans are complete but noisy and miss dependencies absent from manifests, for example in Python. Dynamic scans are relevant but incomplete, add agent overhead and surface findings late. It argues eBPF improves deployability of dynamic SCA but not its coverage limit. A worked example with a library of N vulnerable functions illustrates the difference. The author, Endor Labs, advocates static analysis of source code plus reachability analysis to filter findings by whether vulnerable code is actually called.

  85. Beyond valid credentials: How exposed AWS keys are tested for Amazon Bedrock access

    Datadog Security Labs describes how attackers test stolen AWS credentials for Amazon Bedrock access. It analyses the KMON_NOC harvesting platform's frontend code and two Python checkers from VirusTotal that chain GetCallerIdentity, ListFoundationModels, ListInferenceProfiles and a 4-token Converse "ping", with optional billing:GetCredits. Datadog saw 12 organizations with similar behavior in 30 days and lists detection advice and IOCs.

    A security researcher's thread breaks down CVE-2026-105135, an unpatched critical (CVSS 10.0) remote code execution vulnerability in InternLM's MindSearch agent with a public PoC. The flaw is in ExecutionAction.run in mindsearch/agent/graph.py, which passes the planner LLM's output directly to Python's exec() β€” if the model's reply lacks a code fence, the entire response is executed, and a crafted query to the /solve endpoint can get the model to emit attacker-controlled code that runs as root inside the shipped Docker container (which binds 0.0.0.0:8002). The author notes prompt filtering cannot fix this since the attacker only needs the model's output to contain code, and recommends running any agent that executes model-written code in a network-isolated, non-root sandbox kept off public ports.

  87. HyBind: Structural Analysis of PQ/T Hybrid Cryptographic Usage

    HyBind is an intraprocedural Python static-analysis framework that traces cryptographic component secrets through code to determine whether post-quantum/traditional (PQ/T) hybrid key-derivation and signature-verification logic actually requires both algorithms to succeed, rather than silently accepting a result from only one. It uses registered API contracts and function-return/execution-effect checks to distinguish real AND-logic hybrids from presence-based heuristics that wrongly treat joint and single-algorithm contributions as equivalent. The authors validate it on 50 controlled fixtures and 33 programs (15 using native ML-KEM/X25519 and ML-DSA/Ed25519 APIs), showing relaxed checks can misclassify traditional-only results as hybrid.

  88. Today I learned: Python's .start Files as a Persistence Mechanism

    Explains PEP 829's new .start files in Python 3.15, which let a package register package.module:callable entries in site-packages that execute automatically every time an interpreter starts, before any user code runs. The author walks through a reproducible lab showing code execution via a .start file, contrasts it with the older executable-import .pth file technique it replaces, and gives forensic hunting commands (using python -S to avoid triggering the mechanism during investigation) to locate and audit .start files on disk.

  89. DeepZero

    DeepZero is an open-source orchestration engine that lets researchers define vulnerability-research pipelines declaratively in YAML, handling parallel execution (ThreadPoolExecutor), resumable/fault-tolerant state, and LLM-assessment stages via LiteLLM/Jinja2 prompts. It ships example processors for Ghidra headless decompilation, LOLDrivers.io hash exclusion filtering, PE header/driver metadata extraction, and batch Semgrep scanning, with a dedicated pipeline for BYOVD kernel driver vulnerability research. An extensibility model lets users plug in custom Python processors referenced by path in the YAML config.

    replica-skill is an MIT-licensed set of eleven Claude skills that run an app-cloning pipeline: recon, architect, design, build, backend, test, diff, entrepreneur, brand, launch and deploy. Six standard-library Python tools handle image diffing, parity scoring, review ranking, contrast checks, rebrand sweeps and store-listing lint. It installs as a Claude Code plugin or by copying folders, and states clean-room and rebranding limits.
