Appraisal by AI: Model-driven victim prioritization in the VOLTA infostealerVOLTA (VOLTA-AUTODOXER) is a self-deleting Windows infostealer that, after theft and live session-based enrichment, POSTs an evidence bundle to OpenRouter so an LLM can rank the victim's assets by monetization value. It falls back across a Claude, Kimi and Gemini chain when a model refuses. Talos covers the builder model, the Chrome App-Bound Encryption bypass, the volta_debug.txt artifact and countermeasures such as blocking Chrome --headless.

GPT-6 Astra plays World of Warcraft for the first time with agent-wowagent-wow is an open-source platform that lets LLM agents play World of Warcraft by interacting directly with the AzerothCore private-server network protocol rather than through computer vision or scripted game APIs β the agent itself writes gRPC modules, packet handlers, and even a custom C++ Detour-based pathfinding tool to navigate the world. In this first run, Codex using GPT-6 Astra (xhigh) was given the single prompt 'create an orc character and complete all quests in the starting zone' and completed it unassisted in 40 minutes with zero deaths, data-mining AzerothCore's SQL source for quest/NPC/spawn data to plan its route. The author frames WoW as a long-horizon strategic-planning and real-time tactical-execution benchmark for frontier model agents, comparable in spirit to Mindcraft (Minecraft) and the Factorio Learning Environment, with a stated goal of eventually running many agents through Icecrown Citadel.

The injected runtime code spawns a detached Node process that downloads an encrypted stage-2 loader from IPFS, decrypts it via HKDF/AES-256-GCM, and drops a persistent remote-shell implant self-identified as 'M-RED-TEAM v6.4' with Miasma-branded artifacts, though credential harvesting and self-propagation are disabled in this build. The post includes full technical detail on the exfiltration flow, IOC strings, IPFS CIDs, and inconclusive attribution linking it to the prior Miasma toolkit and prt-scan campaign.

Compromised @injectivelabs/sdk-ts exfiltrates wallet keys through fake telemetryAikido details a compromise of @injectivelabs/sdk-ts (~50,000 weekly downloads), where a hijacked maintainer account published version 1.20.21 containing hooks in PrivateKey.fromMnemonic and PrivateKey.fromHex that capture wallet mnemonics/private keys and exfiltrate them via a POST request disguised as Injective gRPC-web traffic (X-Request-Id header, char-code-obfuscated domain). The attacker simultaneously republished 17 other @injectivelabs-scoped packages pinned to the poisoned SDK version, so any downstream project resolving those transitively pulled the stealer without naming sdk-ts directly. The malicious version was live under an hour, downloaded 310 times, and has since been patched (1.20.23), though the compromised release artifacts remained on GitHub at time of writing.

PolinRider Jumps the Fence to Go, Packagist, npm, PyPIOpenSourceMalware documents how PolinRider, a DPRK/Lazarus Group supply-chain campaign tied to the Contagious Interview cluster, spread from GitHub account takeovers into Go modules, Packagist/Composer packages, npm libraries and Chrome extensions without any change to the malware itself. Because Go and Packagist resolve packages directly from git tags rather than a separately-uploaded artifact, a compromised GitHub account automatically becomes a compromised registry release β unlike npm/PyPI, which require a separate publishing credential and largely stalled the takeover at the registry boundary. The post gives ecosystem-by-ecosystem evidence (10 Packagist packages, 80+ Go modules, an NPM/Chrome cluster), IOCs (TRON/Aptos dead-drop addresses, XOR keys, loader signatures, temp_auto_push.bat), a campaign timeline, and remediation guidance for Go/Composer maintainers.

Huntress recovered and reconstructed "Untitled1.ps1," a PowerShell Active Directory enumeration script used by an attacker during a June 3 incident via RDP access with compromised credentials, and identified it as AI-generated ("vibe-coded") based on artifacts like an unedited LLM placeholder hostname, a "FULLY FIXED" prompt-iteration title, over-engineered five-method DC-discovery fallback logic, and gratuitous colored console/HTML reporting output. The attack chain paired this bespoke recon tool with off-the-shelf abuse of s5cmd (legitimate AWS S3 CLI used for exfiltration) and SharpShares (share enumeration), illustrating how LLM-generated one-off malware evades hash/signature-based detection and pushes defenders toward behavioral analytics on Active Directory enumeration patterns.

Copirate 365 at DEF CON: Plundering in the Depths of Microsoft Copilot (CVE-2026-24299) Β· Embrace The RedJohann Rehberger's writeup of his DEF CON Singapore talk detailing a multi-stage exploit chain against Microsoft 365 Copilot and Consumer Copilot (CVE-2026-24299): indirect prompt injection triggers Copilot's HTML preview feature, CSS background-image/font-face rules bypass img-src CSP and exfiltrate data over font-src, and the attack is made zero-click by instructing Copilot to auto-open the preview. It further chains this with abuse of Copilot's record_memory / durable-facts long-term memory tools (which have no audit logging) to plant persistent "SpAIware"-style instructions that silently exfiltrate any password or secret the user later types, plus Delayed Tool Invocation as a reliability trick and edge_navigate_to abuse in Edge's Copilot to leak stored memories. Includes full disclosure timeline (Oct 2025 report to Dec 2025/Mar 2026 fixes) and broader lessons on CSP not being a reliable AI security boundary and the "lethal trifecta."

Socket: PolinRiderSocket's Threat Research Team documents the expansion of PolinRider, a North Korea-linked (Contagious Interview / Famous Chollima) supply chain campaign, finding 162 malicious release artifacts across 108 packages and extensions spanning npm, Packagist, Go modules, and Chrome extensions. Attackers compromise GitHub maintainer accounts, hide obfuscated JavaScript loaders in fake .woff2 font files or config files, trigger execution via VS Code task files, and use force-pushed/anti-dated commits to disguise malicious changes; the loader fetches second-stage payloads (DEV#POPPER, OmniStealer) via TRON/Aptos/BNB Smart Chain RPC infrastructure for credential and wallet theft.

Miasma & Hades WormsSocket's Threat Research team documents a new wave of 23 malicious PyPI artifacts (bioinformatics packages like embiggen/ensmallen/gpsea/pyphetools, typosquats like rsquests/tlask/rlask, and an MCP-themed langchain-core-mcp package) tied to the ongoing Mini Shai-Hulud/Miasma/Hades supply chain campaign. Unlike earlier .pth-hook wheels that bundled an obfuscated _index.js JavaScript stealer run via Bun, the bioinformatics cluster hides execution inside trojanized .abi3.so native extensions triggered at import time, while langchain-core-mcp ships only a .pth loader that scans sys.path for an external _index.js payload β a loader/payload split designed to evade detection rules. The payload also opens with a fake prompt-injection comment block meant to derail LLM-based static analysis tools before reaching the actual obfuscated stealer code that harvests GitHub, npm, PyPI, cloud, Kubernetes, SSH, and Docker credentials.

Huntress details a live intrusion where an attacker used stolen SSLVPN credentials, Impacket's smbexec.py (a customized fork with randomized artifact names) for lateral movement and registry-hive dumping, then enabled RDP via reg/netsh changes to interactively install the open-source "Komari" monitoring agent as a SYSTEM-level service named "Windows Update Service" via NSSM. Unlike other abused RMM/monitoring tools (Velociraptor, SimpleHelp, ScreenConnect, AnyDesk, Nezha, Atera), Komari ships arbitrary command exec, an interactive PTY reverse shell, and distributed ping/port-scanning enabled by default over a WebSocket that blends in as normal HTTPS traffic β turning a legitimate 4.3k-star GitHub monitoring tool into an out-of-the-box botnet-style C2 with no weaponization required.

rfxn's technical dissection of CVE-2026-41940 (SessionScribe), an unauthenticated session-forgery bug in cPanel/WHM that lets an attacker forge a root cpsess session via CRLF injection into the password field of an Authorization: Basic request, exploiting the fact that Cpanel::Session::saveSession() skips the CR/LF-stripping filter_sessiondata() sanitization used by the normal login path, combined with an encoder short-circuit when the whostmgrsession cookie's OBHEX suffix is malformed. The writeup reverse-engineers the patched cpsrvd binaries (since cPanel ships no source for this surface) using a custom snapshot/BinDiff workflow, documents an adjacent lower-severity access-log identity-injection issue, and ships an open-source operator toolkit (ModSecurity rule pack, remote probe, on-host IOC scanner, snapshot collector) plus an architectural recommendation to firewall cpsrvd's direct ports behind Apache+mod_security2 proxy endpoints.

Using KQL to Detect Gaps in your Conditional Access StrategyA blog post that provides three concrete KQL queries for Microsoft Sentinel/Log Analytics to detect Conditional Access Policy (CAP) violations in Entra ID: single-factor sign-ins by privileged admins that should require MFA, group members bypassing trusted-location/device-compliance requirements, and resources with no Conditional Access applied at all. It also surveys community tooling for CAP gap analysis, including the built-in Gap Analyzer Workbook, Maester, CA Optics, DCToolbox's What-if simulator, and Beau Bullock's MFASweep. The approach turns an organization's intended CAP strategy into ongoing detection logic rather than one-time policy review.

The LNK launches a headless conhost.exe pulling an obfuscated batch script (new.bat) over a trycloudflare.com tunnel, which drops a decoy PDF, downloads a full Python interpreter (FTSP.zip) and additional scripts, and ultimately performs shellcode injection. The post also documents Sysmon process-create telemetry and the HKCU WordWheelQuery registry key as forensic artifacts of the search-ms query.

A DFIR researcher analyzes a PowerShell "cleaner" script discovered in an open directory (flagged by Fox_threatintel) and uploaded to VirusTotal, which threat actors use to erase traces of legitimate RMM tools like Atera and Splashtop after gaining access to a victim machine. The script sets the SystemComponent registry flag to hide the software from Apps & Features, deletes Start Menu/ProgramData installer folders (also targeting AnyDesk), and renames the Splashtop Windows Firewall rule to masquerade as a "Cast to Device" service. The author tests the script on a live machine and shows the anti-forensic tricks are shallow β toggling SystemComponent back to 0 restores visibility and other forensic artifacts still reveal the software.
