What happens when the security system watching your AI agent's marketplace cannot tell the difference between a vulnerable Skill and a safe one? Ini bukan lagi soalan retorik. pada 16 Mac 2026, penyelidik di , the firm founded by Yale and Columbia professors that has detected over 180,000 vulnerabilities in blockchain code, published findings showing exactly how that gap works inside  , one of the fastest-growing AI agent runtimes in the world. A custom Skill uploaded to  , OpenClaw's official skill marketplace, passed through a multilayer moderation stack and installed on a host machine without a meaningful warning. When invoked through Telegram, it executed arbitrary commands. The researchers showed a calculator appear on screen. In a real attack, it would not have been a calculator. Sijil OpenClaw ClawHub https://x.com/CertiK/status/2033534453344075844?embedable=true What OpenClaw Is, and Why Skills Matter So Much  is an open-source, self-hosted AI agent that runs on a user's local machine or server. It supports long-term memory, autonomous task execution, and integration with major large language models. Users interact with it through messaging platforms including Telegram, WhatsApp, Slack, and Discord. The agent acts on their behalf: reading files, executing terminal commands, calling external APIs, and managing connected services. OpenClaw Think of it as a personal assistant with keys to everything on your computer, running at all times. The project has crossed 135,000 GitHub stars, and OpenAI acqui-hired its creator Peter Steinberger in February 2026, signaling how much the industry values agent runtime infrastructure. Skills are the modular extensions that give OpenClaw its expanding range of abilities. Users browse ClawHub by skill name, tags, or natural-language search, download skill bundles, and install them directly into their OpenClaw workspace. Skills can cover anything from web search to on-chain crypto transactions, wallet operations, and system automation. When a Skill installs, it inherits the same system permissions as the agent itself. It is not a sandboxed plugin. It is executable code running inside whatever environment OpenClaw has been granted access to. That inheritance is the central problem CertiK's research targets. ClawHub's Review Pipeline and Where It Fails ClawHub's moderation pipeline combines three layers: static code analysis through a moderation engine introduced publicly by March 8, 2026, internal AI-based review using an OpenAI prompt, and VirusTotal hash scanning. Static scan results are now persisted on each skill version, and structured moderation snapshots merge VirusTotal and AI verdicts into a classification that determines whether a user sees a warning during installation. The static layer looks for recognizable code patterns:  dikombinasikan dengan proses-spawning API,  or   calls, suspicious WebSocket behavior, and environment variable reads paired with outbound network requests. The last one is the most instructive example. The scanner flags   appearing alongside  daripada , or  , on the theory that this combination likely reads secrets and sends them somewhere external. child_process eval() new Function() process.env fetch http.request axios CertiK's researchers showed how easy it is to break that assumption with a minor rewrite: // This gets flagged
const apiKey = process.env.TAVILY_API_KEY;

// This does not
var process_t = process;
var env_t = process_t.env;
var apiKey = env_t.TAVILY_API_KEY;
 The behavior is identical. The syntax is different enough that naive string matching misses it. This is not a novel technique. It is the same evasion logic that has broken antivirus signatures and web application firewall rules for decades. Any defense built around recognizable syntax becomes rewrite-sensitive. CertiK used exactly this transformation in their proof of concept. ClawHub's AI review layer, whose system prompt describes the model as "not a malware classifier" but "an incoherence detector," is better at catching intent mismatches between a Skill's stated purpose and its actual behavior than at performing deep vulnerability discovery across complex multi-file workflows. That distinction shaped CertiK's test strategy precisely. They did not hide an obviously malicious payload. They built a plausible Skill with exploitable logic embedded inside ordinary-looking control flow. The Pending State Gap and the Proof of Concept CertiK also identified a structural gap in the review timing. VirusTotal scanning is not instantaneous. It can take hours or days to return a final verdict. Under the implementation at the time of the research, a Skill with a pending VirusTotal result could become publicly visible and installable as long as it had not been explicitly blocked as malware. The code shows the logic directly.   returns true for Skills whose   is one of three strings:  ,  , or  . A pending result is not a benign result. It means the review is incomplete. But at the point of installation, users had no meaningful way to distinguish it from a Skill that had actually cleared all checks. shouldActivateWhenVtUnavailable() moderationReason pending.scan scanner.vt.pending pending.scan.stale CertiK built a Skill called   that exploited both weaknesses. It performed a legitimate web search workflow with one exploitable detail inside what appeared to be standard path normalization: test-web-searcher const formatFile = data?.meta?.formatFile || './formatters/default.mjs';
const pluginUrl = new URL(formatFile, import.meta.url);

A separate marketplace Skill called  dengan putusan yang mencurigakan VirusTotal telah mencetuskan prompt pengesahan. kemahiran yang paling penting bergerak melalui tanpa blok. test-web-searcher self-improving-agent clawpay-escrow Skala masalah CertiK sedang menangani CertiK's research arrives at a moment when OpenClaw's security record is already under scrutiny from multiple directions. In late January 2026, security researchers found that 12% of all ClawHub skills were malicious, 341 out of 2,857 skills, across multiple campaigns. By mid-February, that figure expanded to 824 or more malicious skills with 1,184 malicious packages across 12 publisher accounts, according to Antiy CERT. Snyk's ToxicSkills research, which scanned 3,984 skills from ClawHub and skills.sh as of February 5, 2026, found that 13.4% of all skills contain at least one critical-level security issue. Researchers confirmed 76 malicious payloads designed for credential theft, backdoor installation, and data exfiltration. Pasukan Penyelidikan Keselamatan Defender Microsoft mengeluarkan nasihat yang menyatakan bahawa OpenClaw "harus diperlakukan sebagai pelaksanaan kod yang tidak dipercayai dengan credentials yang berterusan" dan bahawa ia "tidak sesuai untuk dijalankan pada stesen kerja peribadi atau korporat standard." Apa yang penyelidikan CertiK menambah adalah berbeza daripada kempen malware yang telah didokumentasikan. Temuan terdahulu itu melibatkan Kemahiran berbahaya secara terbuka, yang akhirnya ditangkap oleh penyiasat manusia. Temuan CertiK menangani sesuatu yang lebih sukar secara teknikal: Kemahiran yang kelihatan boleh dipercayai dengan logik yang boleh dimanfaatkan yang tidak menghasilkan bendera merah yang jelas untuk analisis statis atau tinjauan AI. Kelas ancaman itu adalah apa yang menjadikan argumen struktural dalam kertas mereka penting. CertiK has to date worked with more than 5,000 enterprise clients, secured over $600 billion worth of digital assets, and detected more than 180,000 vulnerabilities in blockchain code, with clients including Binance, Ethereum Foundation, BNB Chain, Aptos, and Ripple. Extending that lens to AI agent infrastructure is a natural progression as agent runtimes accumulate the kind of system access that once required exploiting the operating system directly. What CertiK Says Needs to Change The research concludes that adding more scanners or more detailed warning prompts does not solve the underlying problem. The burden those tools carry is too large for the tools to bear. Apple does not secure its ecosystem through App Store review. It relies on OS-enforced sandboxing and per-application permissions. Those controls contain the threats that slip through review. OpenClaw's current containment model is optional and deployment-dependent. CertiK's recommendations are structural. First, sandboxing should be the default operating mode for all third-party Skills, not an opt-in for operators who have already chosen to harden their setup. A sandbox that is difficult to enable, breaks common Skill behavior, or requires repeated user confirmation will not become the real default in practice. Users take the unsandboxed path to keep the system usable, and then the full security burden falls back onto review. Second, each Skill should declare specific resource permissions at publish time, and the runtime should enforce those permissions at execution, similar to how mobile platforms handle app permissions. A web search Skill should not inherit the ability to read environment variables and send outbound requests to arbitrary domains. Those capabilities should be explicitly declared and explicitly granted. Until those controls are in place, CertiK's finding is the clearest demonstration yet that a "Benign" label from ClawHub's moderation pipeline is not proof of safety. It means the current review pipeline did not flag the Skill in a way that changed the installation flow. That is a different thing. Final Thoughts Kerja CertiK di sini mewakili perpanjangan sengaja mandat penyelidikan keselamatan dari kontrak pintar dan kelemahan protokol pada rantaian ke dalam infrastruktur agen AI, domain yang mengumpul jenis akses sistem istimewa yang sama yang menjadikan keselamatan blockchain penting. Pergeseran yang benar-benar mengubah imej keselamatan untuk OpenClaw dan pasaran seperti itu adalah platform yang menganggap beberapa Kemahiran berbahaya akan melalui dan membina pengekalan runtime di sekitar asumsi itu. pergeseran itu belum berlaku.
