VOLTA (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.

Part 2 of an AWS Security Blog series detailing the design of a "steering file" — a persistent instruction set (deployable as a Kiro steering file, Kiro skill, or Claude Code CLAUDE.md) that constrains an LLM performing vulnerability triage. It walks through five configuration sections: requiring structural/dataflow verification before reporting findings, replacing self-reported confidence with a weighted formula based on binary structural signals (e.g., 0.30 weight for confirmed taint flow), mapping infrastructure controls (AWS WAF, IAM) to severity multipliers with a 0.15 floor, incorporating CISA KEV and EPSS threat-intelligence boosts capped at +0.50, and a four-tier priority classification that suppresses low-confidence P3 findings. Validation against a 10-vulnerability test app showed the steered model eliminated fabricated findings and correctly downgraded mitigated vulnerabilities while preserving full severity for a command injection reachable only via authenticated access.

agent-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 — 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 full body text was not available at fetch time, so the specific argument and its relation to corrigibility or value-learning debates could not be confirmed from the page itself.

Horizon3.ai discloses CVE-2026-61500, a session-forgery vulnerability in Rejetto HTTP File Server (HFS) 3.x found using Anthropic's Mythos model. HFS seeds Koa's keygrip session-signing key with V8's insecure, invertible Math.random() PRNG and separately leaks raw Math.random() outputs through an unauthenticated login endpoint; by sampling a dozen leaked outputs and feeding them to the Z3 SMT solver, an attacker can recover the xorshift128+ internal state, step it backwards to the process-start signing key, and forge an admin session cookie that leads to remote code execution via HFS's built-in admin JavaScript execution feature. The piece walks through the full exploit chain and argues that Mythos independently chained the crypto weakness and the leak, built the Z3-based key-recovery solver, and produced a working PoC without additional prompting.

A quoted excerpt from Anthropic's Frontier Red Team report on GLM-5.3 finds that, across 100 randomly selected tasks from an internal Binary Exploitation benchmark, GLM-5.3 achieved full control-flow hijacks in 4% of trials and Claude Mythos Preview in 6%, while earlier models (Claude Opus 4.6, GLM-5.2) succeeded in none. Anthropic frames this as a meaningful threshold crossed in advanced cyber capability, part of ongoing frontier-model dangerous-capability evaluation.

Microsoft's DART team details an investigation into Storm-3068, a threat actor that escalated from a self-service password reset account takeover into full control of an organization's Azure DevOps environment, then weaponized a malicious pipeline to harvest kubeconfig files and gain access to Kubernetes clusters. The actor also deployed the Atera remote management agent and the Chisel tunneling tool to establish reverse tunnels and alternate remote access, and exfiltrated seven stolen kubeconfig files into a repository. The report lays out the attack chain, DART's response, and hardening recommendations around SSPR monitoring, phishing-resistant MFA, branch protection, and pipeline permission controls.

Part 2 of a research series on ZDI-26-708, a Windows Network Connectivity Status Indicator (NCSI) flaw where a proxy configured in an unprivileged user's HKCU ends up used by the NETWORK SERVICE-owned netprofm process. The author reverse-engineers ncsi.dll and winhttp.dll with IDA/WinDbg to show the value actually arrives via a Windows Event Log subscription to Event ID 5600 (Microsoft-Windows-WinINet-Config) rather than the WNF notification initially suspected, is stored in NCSI's user-proxy state, and is later applied to a WinHttpSetOption(38) call for an active connectivity probe. It documents why option 193 (WINHTTP_OPTION_DISABLE_PROXY_AUTH_SCHEMES) fails to disable NTLM (wrong bitmask, 0x100 vs 0x04), and demonstrates cross-context NTLM proxy authentication capture/relay with impacket-ntlmrelayx toward ADCS, since the request runs under the netprofm/NETWORK SERVICE machine-account context.

A researcher reverse-engineers Windows NCSI (ncsi.dll, running under the Network List Service/netprofm as NETWORK SERVICE) to explain how a manual proxy or WPAD/PAC URL set by an unprivileged user gets applied to NCSI's active-probe HTTP request, causing the service account to NTLM-authenticate to an attacker-controlled proxy. On domain-joined hosts this cross-context proxy authentication can be captured/relayed (e.g. via ntlmrelayx) toward ADCS, Shadow Credentials, or RBCD; the finding was submitted to ZDI as ZDI-26-708 and Microsoft declined to assign a CVE, classifying it Moderate-Spoofing.

Huntress researcher Andrew Schwartz demonstrates a novel OAuth token-theft technique: a sideloaded AppX package registered via Add-AppxPackage -Register (requiring only Developer Mode, no admin beyond that toggle) can set ContentUriRules WindowsRuntimeAccess="all" so attacker-controlled JavaScript rendered inside the Microsoft-signed WWAHost.exe process gets full WinRT access, including the legacy WebAuthenticationBroker OAuth API. Using Microsoft Office's own client ID and the oob redirect URI, the attacker triggers a genuine login.microsoftonline.com/MFA dialog with no browser chrome, captures the auth code, and exchanges it for an access token plus a long-lived refresh token carrying the full Office delegated Graph scope set (mail, files, Teams, directory, AuditLog.Create) — validated end-to-end against a live Entra ID tenant with MFA and default Conditional Access. The post frames it as a class of vulnerable signed AppX host binaries sharing the same WinRT activation layer, and provides a Sigma rule keyed on the MSAppHost/3.0 EdgeHTML user agent reaching non-Microsoft destinations, plus Sysmon/Event ID and GPO-based mitigations (restricting Developer Mode, Conditional Access, shorter refresh-token lifetimes, CAE).

Manifold Security discloses 'GitSpawn', a vulnerability class where AI coding agents (Claude Code, Goose, Hermes, Qwen Code, Grok Build, and reportedly Codex/Cursor) run git commands like `git status`/`git diff` for context-gathering at startup without sanitizing the repository's own .git/config. Because these commands refresh git's index, a malicious repo can set `core.fsmonitor` (or a similar config sink) to an arbitrary command, achieving code execution outside the agent's sandbox before any approval prompt, workspace-trust dialog, or even authentication - simply by opening a folder delivered as files (zip, USB, shared drive) rather than cloned. Two CVEs were assigned (Goose, Hermes); four of eight reported findings remain unpatched at publication.

Huntress details a phishing campaign that tricks victims into installing a legitimately signed Faronics Deploy agent disguised as Adobe/Zoom documents, enrolling endpoints into an attacker-controlled deployment console. The threat actors then abuse Faronics' remote script execution to pull PowerShell payloads (via curl, mshta, msiexec) from GitHub-hosted staging and install ScreenConnect for persistent remote access. The post identifies key forensic artifacts (C:\ProgramData\Faronics\Logs\ScriptRunner.log and the deployment's unique "ck" identifier) that defenders can use to trace attacker infrastructure and cluster malicious enrollments, and notes Faronics' response to disrupt abuse after Huntress's disclosure.

Deep-dive reverse engineering of a real-world incident where a WordPress site compromised via CVE-2026-18322 was used to drop a bincrypter-obfuscated, statically-linked gs-netcat (gsocket) 1.4.42beta5 binary as a reverse-shell tunnel, persisted via crontab and masquerading as "netd"/"[kthreadd]". The author fully unravels bincrypter's multi-stage shell obfuscation (character-separator tricks, AES-256-CBC/openssl decryption, memfd_create fileless ELF execution via a Perl one-liner) and reveals a custom THC UPX build with zeroed magic bytes/PackHeader used to hide payload identification, along with gsocket's self-embedded XOR-encoded operator configuration. Releases two open-source tools (Bincrypter-Extract, Gsocket-Config-Extract), YARA rules, and an ImHex pattern file, plus full IOCs (C2 IP, GSRN secret, process/memfd artifacts).

Socket researchers uncovered 19 Chrome and Edge extensions (18 Chrome, 1 Edge) delivering a modular wallet-drainer and credential-stealing framework, tracked as the "Superior" campaign and linked to a 2024 operation first reported by DomainTools and Secure Annex. Threat actors either build extensions from scratch or buy established ones (like "Enable Right Click & Copy — Smart Unlock + OCR" with ~80,000 combined users) and later push malicious updates that strip CSP headers via declarativeNetRequest, open an AES-GCM-encrypted WebSocket C2 channel, and inject JavaScript payloads that phish hardware-wallet seed phrases, hijack wallet-connect flows, harvest exchange session tokens, and serve ClickFix-style fake browser-update lures. The post includes full code snippets, a breakdown of 16+ malicious modules, and a large IOC list of C2 domains and extension IDs.

Huntress SOC documents how threat actors abuse legitimate AI platform features — public Claude Artifacts, claude.ai/share conversation links, and shared ChatGPT/Grok conversations — as trusted hosting for malware lures. Case studies include the "FakeAgent" malvertising campaign (a fake Claude Desktop download Artifact leading to SectopRAT via downloading-api[.]it[.]com), a fake Apple Support guide hosted on claude.ai/share delivering the MacSync stealer via a ClickFix-style curl command, and SEO-poisoned ChatGPT/Grok shared conversations pushing AMOS stealer through fake "clear disk space" advice. It recommends restricting clipboard-driven script execution, application allow-listing, and rapid reporting to AI platform vendors.
