Malicious Claude Code Extension Served in Cursor Supply Chain AttackMalicious versions 2.1.312 and 2.1.313 of the anthropic.claude-code extension were live in the Cursor VS Code Extension Marketplace for about 11 hours on October 29. The JavaScript ran at module load, collected host details, tried to install an SSH key, open a reverse SSH tunnel and set persistence on macOS and Windows. Kevin Beaumont estimates about 5,000 downloads. Cursor rotated keys, rebuilt the marketplace and published a detection script and IoCs; uninstalling alone does not remove the dropped persistence scripts.

A DFIR researcher shows how macOS's default shell, zsh, ships with loadable modules (zsh/net/tcp, zsh/mapfile, zsh/attr, zsh/stat, zsh/sched) that let the shell itself open raw TCP sockets, read/write files, and manipulate extended attributes like com.apple.quarantine without spawning curl, xattr, rm, or nc. The post walks through a full example using ztcp and source /dev/fd/$fd to fetch and execute a second-stage payload directly from a socket (bootstrapping a LaunchAgent) with no downloaded file on disk and no child process, referencing the prior real-world use of zsh/net/tcp for reverse shells (documented by ESET and GTFOBins). It then validates via eslogger/Endpoint Security that DELETEEXTATTR/SETEXTATTR and similar operations remain visible even when performed through zsh builtins, arguing detections should target the underlying OS event rather than the specific binary invoked.

Huntress SOC analysts Ryan Dowd and Jon Semon tore apart a live social-engineering campaign that began with a fake CoinDesk marketing exec DMing a researcher a Google Doc containing a container-bound Apps Script sidebar. The script ran client-side without OAuth consent, exfiltrated victim IP/geolocation/wallet presence via the Telegram API, then routed macOS users to a piped zsh/DMG AMOS stealer chain and Windows users through ClickOnce and PowerShell loaders using three stolen or fraudulent code-signing certificates (a Norwegian company, Discord, and Lenovo). The Windows chain culminated in NetSupport Manager RMM abuse, a Ledger wallet implant, and a self-generated rogue root certificate authority (spoofing Google Trust Services) installed via MsBuild.exe hollowing to silently intercept HTTPS traffic, which the authors flag as the artifact most likely to survive incident remediation short of full reimaging.

Concrete outputs include two new Go standard library CVEs (CVE-2026-33809 TIFF OOM, CVE-2026-33812 SFNT/GPOS OOM), a four-stage Windows OEM management-agent chain (named-pipe auth bypass → SSRF via WCF → catalog injection → SYSTEM code execution via BYOVD), and two macOS app-distributor findings (browser/quarantine DB exfiltration and a leaked debug RSA key enabling Sparkle update-signature bypass). Also covers a self-built token-cost/ROI tracker (TokenBurn) and a bounty-program ROI-scoring model for target selection.

hack-skills is a GitHub repo (yaklang/hack-skills) that packages offensive security knowledge into installable "Agent Skills" — one master entry, six category entries, and 102 deep-topic SKILL.md files across 14 domains including web/API security, auth, Linux/Windows/macOS privilege escalation, Active Directory attacks, mobile, binary exploitation, reverse engineering, crypto attacks, blockchain/smart contracts, AI/LLM security, network pivoting, and forensics. It's designed for AI coding agents (installed via `npx skills add yaklang/hack-skills` or a raw SKILL.md URL) to use during authorized pentesting, bug bounty, and CTF work, and explicitly strips destructive PoCs (DROP/TRUNCATE, FLUSHALL, service shutdown/DoS) in favor of non-destructive proofs like time-based SQLi and read-only recon, while retaining RCE/webshell/reverse-shell primitives as access proofs.

SeldomMonster is a collection of Model Context Protocol servers built for Gemini CLI (but MCP-generic) that wrap free/community cyber threat intel APIs — GreyNoise, Malpedia, OpenCTI, AlienVault OTX, ransomware.live, IBM X-Force, YaraHub, blockchain transaction lookups, and r/netsec/r/blueteamsec feeds — plus a separate set of macOS tools (Nmap as the only third-party dependency) for discovering and hacking devices on the local network. It's a practical toolkit for wiring an LLM agent directly into IOC enrichment, ransomware tracking, and local network recon/exploitation workflows.

Trail of Bits AI-Native JourneyTrail of Bits describes the internal "operating system" it built to make itself AI-native: a standardized Claude Code toolchain, an AI usage-policy handbook, a capability maturity matrix, recurring hackathons run in "bypass permissions" autonomous-agent mode, and six open-sourced repos (skills, skills-curated marketplace, claude-code-config, claude-code-devcontainer, dropkit macOS sandbox, slither-mcp) that package 94 plugins/201 skills/84 agents. Security-relevant specifics include treating agent autonomy as requiring sandboxing and hardened defaults by default, a curated skills marketplace to avoid backdoored third-party AI plugins, prompt injection to client codebases flagged as an unsolved "existential" risk (with pointers to kernel-level agent shells like nono and agentsh), and claims that AI now surfaces ~20% of bugs in client audits (15→200 bugs/week on some engagements). It's largely an org-process/adoption piece rather than a technical deep-dive, but the linked tooling and the agent-security framing make it useful for teams rolling out autonomous coding agents safely.

Huntress blog on how social engineering has outpaced traditional prevention-focused security programs, citing specific campaigns: EvilTokens, a phishing-as-a-service operation that weaponized the Railway cloud deployment platform and Cloudflare Workers to run OAuth device code phishing against 340+ organizations, and a campaign using fake ChatGPT/Grok search results to trick macOS users into installing the AMOS infostealer. Also discusses AI-driven deepfake identity attacks and alert fatigue undermining detection.
huntress.comarticleAdded 3 Sep 2026, published 1 May 2026🛡️ Security - Attackers Didn’t Wait for AI. They Built Workflows Around It.
Huntress details three real-world patterns where attackers build workflows around AI adoption rather than attacking AI models themselves: SEO-poisoned/malvertised fake "Claude Code" downloads that deliver credential-stealing malware, an AMOS stealer campaign that spoofs ChatGPT/Grok-style answer pages to trick macOS users into running malicious Terminal commands (ClickFix-style), and the EvilTokens phishing-as-a-service platform, which used Railway infrastructure for on-demand session-token theft and AI-generated, role-tailored phishing lures that bypass email filtering. The piece argues AI isn't the weapon but the accelerant, making malicious activity blend into trusted, expected workflows.

Huntress recounts an incident in which one of its own engineers clicked a sponsored Google Ads result impersonating "Claude Code" and downloaded malware onto his MacBook. The payload used base64 encoding and gzip compression to obfuscate a second-stage script that targeted the macOS keychain for Claude Code credentials, while an obfuscated AppleScript further hid its behavior; the engineer's immediate self-report let Huntress's SOC rotate credentials before attackers could use them. The piece is part technical incident summary, part culture commentary on rewarding fast, blame-free reporting of security mistakes.

Huntress's rapid-response analysis of the March 2026 compromise of the axios npm package, in which an attacker took over maintainer jasonsaayman's npm account and published backdoored axios releases (5.14.1, 4.2.1) depending on a phantom package plain-crypto-js whose postinstall script dropped a cross-platform RAT to macOS, Windows, and Linux. The writeup details the obfuscated dropper (setup.js), platform-specific payloads (wt.exe EDR-evasion trick on Windows, com.apple.act.mond on macOS, /tmp/ld.py on Linux), the shared C2 protocol at sfrclak[.]com, and evidence tying the campaign to DPRK-linked actors (UNC1069/BlueNoroff), plus remediation and hardening guidance.

Huntress's AI-Centric SOC details an incident where a user was tricked by a fake "macOS Protection Service" pop-up into entering their password, launching the MacSync infostealer. MacSync harvested Apple Keychain credentials, Chrome/Safari cookies, 200+ crypto wallets, and documents into /tmp/salmonela/, zipped the loot, and used curl to POST it to a C2 server before Huntress Managed EDR flagged the LOOBins-based activity, isolated the host, and stopped exfiltration.

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 — a BlackBasta-linked SOCKS backconnect proxy malware that routes attacker traffic through the victim's machine to bypass MFA and anti-fraud checks — 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.
huntress.comwriteupAdded 3 Sep 2026, published 4 Mar 2026🛡️ Security - Introducing MacNoise!
MacNoise is a modular, open-source macOS telemetry noise generator built to help defenders validate EDR, SIEM, and firewall detection coverage by emitting real system events — network connections, process spawns, dylib injection, file writes, plist mutations, TCC permission probes, and launch agent persistence. It ships a REPL (macnoise run/list/info/scenario), a dry-run testing mode, and OCSF-compliant JSONL audit/telemetry logs tagged with MITRE ATT&CK mappings and correlation IDs, and supports YAML "scenarios" that chain modules to emulate specific adversary tradecraft (e.g., an EDR Validation Suite covering proc_inject, net_dns, tcc_fda). It's positioned as a macOS-focused complement to the EDR-Telemetry project and Windows-centric atomic-testing tools, aimed at surfacing logging gaps before an incident.

Huntress's Principal EDR Product Researchers explain how their Managed EDR collects telemetry differently on Windows (kernel callbacks, ETW, Event Log, AutoRuns point-in-time surveys), macOS (Apple's Endpoint Security API, TCC/Gatekeeper constraints, code-signing enrichment), and Linux (eBPF hooks, file-activity-as-persistence-proxy), and why full feature parity isn't always pursued. It also details their Ransomware Canaries capability (260+ confirmed-ransomware alerts in 2025 on Windows) and why canaries aren't yet prioritized on macOS/Linux given the current threat landscape (citing Akira SMB-based remote ransomware, EvilQuest/ThiefQuest VirusTotal sample inflation, and a non-viable 2023 macOS LockBit variant noted by Objective-See's Patrick Wardle).

Other fixed issues include an App Store bug exposing payment tokens, a malicious-image memory corruption flaw, unauthenticated access to Hidden Album photos, and passwords being unintentionally exposed during remote FaceTime control sessions.
macrumors.comarticleAdded 3 Sep 2026, published 14 Dec 2025🛡️ Security- AI-Poisoning & AMOS Stealer: The Biggest Mac Threat | Huntress
Huntress details a December 2025 incident where attackers used SEO poisoning to surface fake, attacker-created ChatGPT and Grok shared conversations as top Google results for benign queries like "clear disk space on macOS." Victims who followed the AI-formatted "troubleshooting" instructions and pasted a Terminal command triggered a multi-stage AMOS (Atomic macOS Stealer) infection: a bash loader silently validated the user's password via `dscl -authonly`, escalated to root via `sudo -S`, deployed a hidden `.helper` Mach-O payload, trojanized Ledger Wallet and Trezor Suite apps to steal seed phrases, and persisted via a LaunchDaemon-driven AppleScript watchdog that relaunches under the active GUI user's session every second. The piece is notable as the first documented case of AMOS using AI-platform-hosted content (rather than phishing or fake installers) as the initial lure, and includes defender detection guidance (monitoring osascript credential prompts, dscl -authonly usage, sudo -u with piped passwords, hidden dotfiles).

A DFIR.ch case study walks through macOS extended attributes (EAs) using xattr, ls, and mdfind to inspect metadata like com.apple.quarantine and com.apple.metadata:kMDItemWhereFroms on a downloaded Webex.dmg file. It shows how incident responders can query the LSQuarantineEvent SQLite database (~/Library/Preferences/com.apple.LaunchServices.QuarantineEventsV*) to recover download URLs and timestamps for forensic investigations, references a Velociraptor hunt (MacOS.System.QuarantineEvents) for automated parsing, and demonstrates removing the quarantine attribute with xattr -d to bypass Gatekeeper's download warning.

A short DFIR 'Today I Learned' post explaining that Zsh keeps in-session command history with timestamps accessible via `fc -lf` or `fc -li 100`, unlike the on-disk ~/.zsh_history file which loses per-command timestamps after reboot. The author recommends analysts capture this during live response and suggests configuring HISTTIMEFORMAT permanently to preserve timestamps for future investigations. Relevant to incident responders working on macOS (default shell since Catalina), Kali Linux, and Gentoo systems.
