  3. Gheist: Attempted Scaled Abuse of Stolen GitHub Tokens Stumbles

    Gheist is a campaign tracked by Wiz Research since 15 September 2026 that uses stolen GitHub tokens to push a sync-check workflow on ci-sync-* branches in every reachable repository. The workflow prints base32-encoded secrets into logs, which the tool downloads through the GitHub API and then deletes. Over 13,500 branches from 850+ accounts were recovered. The post covers the two tool variants, a buggy self-hosted runner payload, GitHub's approval hold (which does not cover private repositories), overlaps with other campaigns, hunting queries, IOCs and hardening steps.

    Socket's Threat Research team reports that malicious cache.yml workflows ran in the BerriAI/litellm repository on 10 and 12 October 2026, eleven days before the 21 October release attack that published litellm==1.107.0. Each commit pushed to a short-lived ci-tmp-<hex> branch, then deleted it, sending base64-encoded CI secrets to webhook.site. Evidence comes from Actions metrics and environment deployment records; 20 secret names were exposed.

  15. Six defects in one signature verification tool, found from outside in six rounds

    A forum writeup on ethresear.ch describing a "predictions-first" testing methodology for verification logic, applied against the author's own repository and against a live third-party MCP server (nsgoods Workbench, which offers offline signature verification over the x402 payment catalogue). Six rounds of testing surfaced concrete defects: a false negative caused by a stripped field list, a tamper-accepted body via a service-selection parameter that let callers choose which fields were excluded from the signed message, schema-rejection and signature-failure returning byte-identical error text, and a logging/privacy gap in the operator's system that was fixed after disclosure. The author ships a companion tool, exactzk-verification-guards, which captures both a passing and an actually-reproduced failing run as regression evidence rather than a fabricated example.

The conversation ranges across AI-generated GPU kernels and their verification gap, research taste in academia versus industry labs, why "harnesses" (as in Claude Code, Codex, and Pi) function as compositional generalizers, the Jev model's non-autoregressive output-space trade-offs, and large-scale agent swarm experiments at OpenAI, Kimi, and Sakana AI. It offers a researcher's-eye view of where capability overhang and new agent/harness architectures may be heading beyond today's standard transformer decoder.

  17. Trust minimized transaction simulation using state proofs

    An ethresear.ch post proposing "verified prestate simulation": wallets fetch the prestate a transaction will touch via debug_traceCall's prestateTracer, confirm unanimous state-root agreement across multiple independent RPC nodes, verify each account/storage value with eth_getProof Merkle Patricia Trie proofs, and only then execute the transaction locally with revm to produce trustworthy simulation results. It targets a concrete wallet attack where a compromised simulation API/RPC provider shows a benign fake trace (e.g. "donate to charity") while the real calldata drains a user's funds, and discusses its limitations (prestate-completeness not yet verified, conditional-logic and MEV evasion still possible) as a pragmatic alternative to full light clients.

  20. Getting the Source Right, Not Just the Fact: Source-Aware Verification for MCP Agents

    A research writeup from Multiverse Computing introducing ProvenanceGuard, a post-generation verification layer for MCP-based LLM agents that checks not just whether a claim is factually supported somewhere in retrieved evidence, but whether it is attributed to the correct source tool or document, a failure mode they call cross-source conflation. Using local models (MiniLM for source routing, a DeBERTa NLI verifier, and a local LLM for claim decomposition) plus a RARR-style repair loop, it was evaluated on 281 real MCP traces from a medical agent, catching 138 of 139 unsupported claims flagged by human experts and correctly identifying the exact source about 86% of the time on held-out data, outperforming four source-blind baseline checkers. The method has already been adopted in NVIDIA's NVFlow finance-agent grounding stage.

  21. AI Agent Sandbox Flaw in brig: Symlink Traversal (CVSS 8.2) | Blog | Endor Labs

    Endor Labs researcher pkennedy details GHSA-wp6x-29qx-fpr7 (ENDOR-VUL-2026-1809, CVSS 8.2, CWE-59), a symlink-traversal flaw in brig, a tool that runs AI coding agents inside microVM/container sandboxes. While brig's shared working directory was carefully guarded against symlink swaps, the user-named project directory was passed to the underlying runtime (Virtualization.framework on macOS, containerd/nerdctl on Linux) as a raw unresolved path; an agent could replace a subfolder it already controls with a symlink to any host directory, which is then mounted read-write into the sandbox on the next run, exposing SSH keys, cloud credentials, and other projects with the operator's privileges. Fixed in brig 0.3.0 by resolving and holding the path open before mounting; the piece includes full PoC commands, root-cause code snippet, and a detailed vendor disclosure/CVSS negotiation narrative.

    GitHub Security Lab describes custom "taskflow" prompts built on their open-source Taskflow Agent to hunt Android app vulnerabilities, reporting 24 findings to date. It walks through two concrete chains: an exported, unprotected MapActivity in OsmAnd that lets any app silently import settings and exfiltrate the user's exact map tile/route coordinates to an attacker server, and a hostname-parsing logic bug plus overly loose cookie-domain check in the Wikipedia Android app that lets a wikipedia:// deeplink load an attacker page (e.g. evil-wikipedia.org) and steal long-lived session cookies for account takeover. The post also candidly notes where LLMs struggle (false positives, mis-estimating severity, missing mitigating factors) versus where they excel (deep knowledge of safe/unsafe API patterns).

    A technical ethresear.ch post proposing post-quantum upgrades (schemeId 2-6) to Ethereum's Stealth Address Protocol (ERC-5564/ERC-6538), replacing ECDH with ML-KEM (FIPS 203) to preserve recipient unlinkability against a cryptographically-relevant quantum computer. It identifies a specific vulnerability: the naive 1-byte view-tag optimization leaks enough information for a quantum attacker holding the derived public key to recover the spending key discrete log and test candidate recipients, breaking anonymity even when ML-KEM is used; the authors propose domain-separated tag derivation, hybrid EC/PQ combiners, pairwise-KEM variants, and a "stealthier SAP" construction to fix it.

    A Flashbots researcher reviews the EarlyAttestationBleed paper (Muhammad Usama Sardar and Songbo Bu), which uses ProVerif formal analysis to uncover three attestation-verification bugs in confidential-computing deployments: Cocos AI's TDX verifier fails to actually compare the REPORT_DATA value despite computing it correctly, Cocos AI's SEV-SNP validator skips the comparison entirely when an empty expected-input value is passed, and Edgeless Systems' Contrast workload-policy logic can be tricked into accepting container images from untrusted host-controlled storage due to a rebase mistake. All three were implementation bugs (not protocol design flaws) and have since been fixed; the post also summarizes the paper's broader concerns about "early attestation" โ€” exposing hardware details pre-authentication, lack of post-handshake re-attestation for long-lived sessions, and handshake-timeout tradeoffs from added attestation latency.

  33. A โ€œproofโ€ of Fermatโ€™s Last Theorem that fits the margin

    Trail of Bits found a bug in Lean's String.Pos.Raw.extract (affecting all stable versions up to 4.33.1, fixed in 4.34.0-rc1) where the logical definition and the compiled native code disagree on the result of extracting a slice at an out-of-bounds position, letting an attacker manufacture a contradiction (empty string = non-empty string) that "proves" any theorem, including a fake formalization of Fermat's Last Theorem. The exploit only works when a proof relies on the native_decide axiom, which extends trust to the compiler rather than the kernel; the researchers found the issue while using GPT-5.6 to build a code-review skill, and Lean maintainers hargoniX and Rob23oba shipped fixes within hours to days of disclosure. The post is a reminder that machine-checked proofs are only as trustworthy as the evaluator/compiler paths behind axioms like native_decide, and points to work like lean4lean and alternative kernels as mitigations.

  36. An AI-Assisted Cyber Attack: Inside a Unit 42 Investigation

    Unit 42 details an incident response engagement in which a threat actor used frontier AI models and custom agentic AI frameworks to compress a multi-week intrusion into under 10 hours, executing over 50 MITRE ATT&CK techniques largely autonomously. The AI agents mapped internal microservices after breaching a public web service, harvested hard-coded secrets from code repositories, escalated to root via a secrets manager, hijacked CI/CD pipelines to exfiltrate cloud keys (attempting but failing to backdoor Terraform via branch protection), and ultimately hijacked the victim's own cloud AI endpoints as post-compromise infrastructure. The article maps techniques to MITRE ATT&CK and ATLAS, lists AI-usage indicators (structured Markdown handoffs between agent sessions, AI-generated scripts) and offers defensive recommendations like synchronized automated containment, treating AI endpoints/MCP gateways as governed infrastructure, and hunting for bursty API/auth behavioral loops.

    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.

The bug affected 82 live mainnet markers (tokenized loans, bridged stablecoins, consortium deposits, governance escrow) and allowed two-transaction exploitation to mint arbitrary tokens or drain roughly $500,000 in escrowed nhash; it was mitigated in v1.28.0 (PR #2627) and fully fixed in v1.29.0 (PR #2734) by reading live bank-module supply with an explicit zero-guard.

  39. The Term Finance Exploit: $8.5M Approved by Silence

    A transaction-level forensic reconstruction of the August 23, 2026 Term Finance vault drain ($8.5M), in which an attacker funded a wallet via Tornado Cash, deposited a trivial 0.017% stake, and used it to submit an executable governance proposal through Term's opt-out "veto" voting model. The payload sat publicly visible on-chain for six days with no objection, then disabled the seven-day Zodiac delay-modifier timelock from inside the same proposal it was supposed to be gated by, before draining four ETH sub-vaults and five USDC vaults (including contagion into a RockawayX/Tori Finance curated vault). The piece dissects why the exploit required no leaked key, oracle manipulation, or reentrancy โ€” only an unwatched veto queue and a timelock reachable by the mechanism it was meant to contain.

Key techniques include letting Codex write and red-team its own goal prompts, defining precise outcomes rather than prescribing methods, running one outcome per agent to avoid competing objectives, and building an automated variant-analysis pipeline (using P-critical Rust issues, a security gate, and a two-pass false-positive judge) that produced a soundness hole and a miscompilation patched in Rust 1.98, plus privilege-escalation bugs in Keycloak's SAML component. They also built agentcov, an internal tool that tracks code coverage read by Codex to prevent it from skipping parts of the codebase.

The workflows execute on GitHub-hosted Ubuntu runners on every push, download an architecture-matched Linux payload from C2 server 43.228.157.68, and run an internet scanner (`ipscan --exploit CVE-2026-41940`) that exploits an authentication bypass in cPanel/WHM and harvests cloud, database, SSH, and source-control credentials, exfiltrating results via heartbeat/results HTTP endpoints and DNSHook callbacks. GitHub code search for the campaign's unique markers returned 6,100-16,000 matching workflow files across unrelated repositories, indicating the abuse extends far beyond the one compromised maintainer and effectively weaponizes GitHub Actions as free, disposable attack infrastructure.

  53. AgentBaiting: How Fake AI Skills Deliver Malware at Scale

    Island Research uncovered the FakeGit campaign: roughly 7,600 malicious GitHub repositories (from ~6,600 fake developer profiles), over 800 of which impersonate AI Skills or MCP servers for tools like Gmail, WhatsApp, Databricks, Jenkins, and Docker, collectively logging 14M+ downloads and 600+ listings across registries like LobeHub, Glama, MCP.so, and MCP Market. Malicious READMEs and bundled ZIPs (e.g. Mann1988/awesome-claude-skills, DomingosNgongo/walmart-mcp, 45d5r/databricks-mcp-server) drop a LuaJIT-based loader that runs an obfuscated Lua stage, resolves C2 via a Polygon smart contract, and ultimately injects the StealC infostealer via SmartLoader. The report's core finding, dubbed "AgentBaiting," is that Claude Code, Gemini, and ChatGPT independently discovered and recommended these fake capability repos as installation instructions without ever being given a link, showing agentic search/discovery itself has become a supply-chain attack surface.

Because build.rs executes automatically at compile time via Cargo, simply building a project that depends on the crate is enough to trigger the leak, making it a novel build-time supply-chain attack vector distinct from the npm/PyPI postinstall-hook pattern, and notable for exfiltrating source code diffs rather than credentials.

The payload scrapes GitHub Actions Runner.Worker process memory to steal masked CI/CD secrets, harvests 130+ credential file paths (cloud, SSH, Kubernetes, Vault, crypto wallets, Claude Code/VS Code configs), exfiltrates via a GitHub API dead-drop in antvis/G2 or a fake-OpenTelemetry C2 at t.m-kosche.com, drops persistent backdoors in Claude Code/VS Code, and has already used stolen GitHub tokens to spin up 2,500+ dead-drop repositories. The writeup includes full process/network telemetry from Harden-Runner showing the attack blocked, deobfuscated payload internals, IOCs, and detection/remediation guidance.

  74. Quacc++

    Somerset Recon details Quacc++, a proof-of-concept automated bug hunter that queries grep.app's regex-based index of public GitHub repos to find candidate vulnerable code, downloads matching repositories, and runs Semgrep taint-analysis rules to confirm exploitable patterns. Using a search for strcpy(buf, argv[ paired with a custom Semgrep taint rule, the authors discovered an unbounded strcpy stack buffer overflow in GetArgumentFiles() in Google DeepMind's Lab repository (engine/code/bspc/bspc.c), confirmed with AddressSanitizer and pwntools/GDB to give full RIP control at offset 1080. The post also walks through Semgrep rules for SQL injection (CWE-89), hardcoded API keys (CWE-798), and disabled TLS certificate validation (CWE-295) across curl/wget/requests/Node/Go.

  75. The 60ms Window: How Event 5156 Solves the ADWS Attribution Problem

    Huntress researchers solve the long-standing 'ADWS attribution problem' where tools like SOAPy abuse Active Directory Web Services to hide the attacker's real source IP behind localhost ([::1]) in LDAP diagnostic logging (Event 1644). By correlating Windows Filtering Platform Event 5156 (which captures the real inbound source IP on port 9389 before ADWS proxies to loopback) with Event 1138 (ADWS session) and Event 1644 (LDAP query) using a stable ~60-80ms timestamp window, they demonstrate reliable attribution even when port-based correlation fails due to log rollover. The post includes a released PowerShell script (Get-ADWSAttribution.ps1) and addresses the false-positive concern of RSAT tools also using ADWS via pattern detection on suspicious 1644 query attributes.

  76. Training State of the Art Vulnerability Discovery Agents through Reinforcement Learning | depthfirst

    dfs-mini1 is a vulnerability detection agent from depthfirst, built by reinforcement learning on gpt-oss-120b with a shell-only harness. Trained in Kubernetes sandboxes on audits that do not overlap EVMBench, using a 32k context with learned summarization, it reaches state of the art on EVMBench Detect at pass@8 at 10-30x lower cost than frontier models. It also transfers to an internal CVE benchmark, but reports more false positives.

  77. A Threat Actor Abuses Another Free Trial

    Huntress documents a threat actor who exfiltrated data stolen from SolarWinds Web Help Desk, ToolShell/SharePoint, Gladinet CentreStack, and SmarterMail intrusions into a free-trial Elastic Cloud SIEM instance, using Kibana's Discover interface to triage roughly 216 victim hosts across 34 Active Directory domains. Collaboration with Elastic, Unit 42, and Black Lotus Labs uncovered disposable-email infrastructure (quieresmail.com/firstmail.ltd), Cloudflare Workers used for Velociraptor callbacks, and login activity via a Safing SPN/VPN tunnel before Elastic took the instance down. The post is part two of a series exposing how the actor abuses legitimate free-trial security software for post-exploitation victim management.

  78. How Fake OpenClaw Installers Spread GhostSocks Malware

    Huntress investigated malicious GitHub repositories impersonating OpenClaw installers (Feb 2-10, 2026) that were surfaced as the top Bing AI search result for "OpenClaw Windows." The Windows installer deployed a new packer dubbed Stealth Packer alongside Vidar and PureLogs infostealers and GhostSocks โ€” a BlackBasta-linked SOCKS backconnect proxy malware that routes attacker traffic through the victim's machine to bypass MFA and anti-fraud checks โ€” while a parallel macOS campaign delivered a signed Mach-O AMOS stealer variant via a fake "puppeteerrr/dmg" repo, later detected by an Apple XProtect update. The blog includes full technical teardown, GitHub account/organisation abuse patterns, and IOCs.

  79. Manual Configuration Manager (SCCM) credential harvesting

    A step-by-step method for harvesting Configuration Manager (SCCM/MECM) credentials by pulling DPAPI-encrypted secret policy blobs (Network Access Accounts, task sequences, collection variables) via WMI or the local CIM repository, then exfiltrating DPAPI master keys and LSA SYSTEM/SECURITY/SAM hives for fully offline decryption with Impacket's dpapi and secretsdump modules. The approach avoids running known SCCM-abuse tools like SharpDPAPI on-target, reducing signature-based detection while still noting which steps (registry hive backup, DPAPI folder copy, WMI queries) a SOC could realistically catch.

  80. Linux Capabilities Revisited

    A DFIR.ch technical walkthrough of Linux POSIX capabilities: how to weaponize cap_setuid on a binary like /usr/bin/python3.12 with setcap to create a stealthy root-spawning backdoor without touching SUID bits, then how defenders can hunt for these via getcap -r, /proc status Cap* fields, LinPEAS, and an Elastic detection rule that flags setcap process execution. It also explains where capabilities live on disk (the security.capability extended attribute on the inode) and how to inspect/remove them with getfattr and setcap -r.

  81. Oh my .. ! - Suspicious network traffic detected including Ransomware

    A DFIR consultant walks through two Microsoft Defender for Endpoint high-severity "Ransomware" alerts that turned out to be benign inbound TCP SYN scans (ConnectionAttempt, not InboundConnectionAccepted) from an IP Microsoft had classified as malicious. The post shares KQL queries against DeviceNetworkEvents to identify internet-facing devices (via RemoteIPType and InboundInternetScanInspected), explains the difference between ConnectionAttempt and InboundConnectionAccepted ActionTypes, and stresses correlating with DeviceLogonEvents before concluding an alert is a false positive.

  82. Privileges relinquishing order in C

    Explains a subtle Linux privilege-dropping bug: calling setuid() before setgid() in a SUID/SGID-root binary leaves the saved set-group-ID privileged, letting a later setgid(0) call silently regain root group privileges due to POSIX semantics. The author provides compiled C PoC programs (drop_bad.c / drop_good.c) showing the wrong order failing to fully drop privileges versus the correct order (setgid then setuid) properly relinquishing them, and notes this becomes exploitable for privilege escalation when combined with a code-execution bug later in the program.

  83. From Dangerous PHP Functions to Webshell Hunting

    A DFIR practitioner deploys four PHP webshells (popen-based, proc_open-based, p0wny-shell, and Weevely) on a test web server, then tests whether common webshell YARA rulesets (nsacyber, Florian Roth's Thor rules) can detect them via Velociraptor hunts. The rules only catch p0wny-shell due to its many code-execution keywords, missing the simpler popen/proc_open shells and Weevely entirely, exposing brittleness in signature-based webshell detection. The author proposes a semi-automatic approach combining Velociraptor/DetectRaptor with manual review, web-log frequency analysis, and UAC-generated bodyfile/mactime timelines to hunt webshells more reliably.

    dfir.ch documents an incident response investigation where an NDR sensor flagged a suspicious internal port scan. The analyst used EDR telemetry to identify the responsible PowerShell script (hash-verified, Microsoft-signed) invoking Defender for Endpoint's Device Discovery feature (Scan-UdpTcpPorts, Scan-Vnc, Scan-WinRm, etc.), decoding its base64 ScannerArgs to reveal target IPs, MACs, and the CVEs it probes for (CVE-2021-44228, CVE-2022-22965). The scan turned out to be benign legitimate network discovery from Defender for Endpoint, explaining why it triggered an NDR false positive.

  85. PHP's open_basedir is not a security feature

    The author dissects PHP's open_basedir directive by reading php-src's php_check_open_basedir enforcement code, and finds two functions โ€” bindtextdomain() and opcache_invalidate() โ€” that fail to call the guard, allowing an attacker to use them as file-existence oracles outside the restricted directory tree (tested on PHP 8.0.7, reported to maintainers 2021-07-12). It also documents PHP maintainers' longstanding position that "open_basedir bypasses are no security issues," and notes the PHP manual was subsequently updated to caution that open_basedir is only an extra safety net and must not be relied upon for security.
