Hvad sker der, når sikkerhedssystemet, der overvåger din AI-agents markedsplads, ikke kan fortælle forskellen mellem en sårbar færdighed og en sikker? That is not a rhetorical question anymore. On March 16, 2026, researchers at  , firmaet grundlagt af Yale og Columbia professorer, der har opdaget over 180.000 sårbarheder i blockchain-kode, offentliggjorde resultater, der viser nøjagtigt, hvordan dette hul fungerer inde , en af de hurtigst voksende AI agent runtimes i verden. En brugerdefineret færdighed uploadet til , 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. CertiK Åbentøj ClawHub https://x.com/CertiK/status/2033534453344075844?embedable=true What OpenClaw Is, and Why Skills Matter So Much er en open-source, selvhostet AI-agent, der kører på en brugers lokale maskine eller server. Den understøtter langtidshukommelse, autonom opgaveudførelse og integration med store store sprogmodeller. Brugere interagerer med det via meddelelsesplatforme, herunder Telegram, WhatsApp, Slack og Discord. Agenten handler på deres vegne: læse filer, udføre terminalkommandoer, ringe til eksterne API'er og styre forbundne tjenester. Åbentøj 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. Når en Skill installeres, arver den de samme systemrettigheder som agenten selv. Det er ikke en sandkasse-plugin. Det er eksekverbar kode, der kører i ethvert miljø OpenClaw har fået adgang til. 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:  i kombination med process-spawning APIs, eller opkald, mistænkelig WebSocket-adfærd og miljøvariabler læses sammen med outbound-netværksforespørgsler.  appearing alongside  , der eller , på teorien om, at denne kombination sandsynligvis læser hemmeligheder og sender dem et sted eksternt. 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. Den udestående statsgap og bevis for konceptet 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.  Returnering af de færdigheder, der  is one of three strings:  , der eller . 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  Det udførte en legitim websøgning arbejdsproces med en udnyttelig detalje inde i, hvad der syntes at være standard path normalisering: test-web-searcher const formatFile = data?.meta?.formatFile || './formatters/default.mjs';

The Skill that mattered most moved through without a block. test-web-searcher self-improving-agent clawpay-escrow The Scale of the Problem CertiK Is Addressing 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. Snyks ToxicSkills-undersøgelse, der scannede 3.984 færdigheder fra ClawHub og skills.sh pr. 5. februar 2026, fandt, at 13,4% af alle færdigheder indeholder mindst et sikkerhedsproblem på kritisk niveau. Microsoft's Defender Security Research Team issued an advisory stating that OpenClaw "should be treated as untrusted code execution with persistent credentials" and that it "is not appropriate to run on a standard personal or enterprise workstation." Hvad CertiK's forskning tilføjer, er forskellig fra de malware-kampagner, der allerede er dokumenteret. De tidligere resultater involverede åbenlyst ondsindede færdigheder, der til sidst blev fanget af menneskelige auditører. CertiK's fund adresserer noget teknisk sværere: en plausibel-looking Skill med udnyttelig logik, der producerer ingen åbenlyse røde flag for hverken statisk analyse eller AI-gennemgang. Den klasse af trusler er, hvad der gør det strukturelle argument i deres papir vigtigt. 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. For det andet skal hver Skill erklære specifikke ressourcetilladelser på offentliggørelsestidspunktet, og runtime skal håndhæve disse tilladelser ved udførelse, svarende til, hvordan mobile platforme håndterer apprettigheder. En websøgning Skill bør ikke arve evnen til at læse miljøvariabler og sende outbound anmodninger til vilkårlige domæner. 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. Afsluttende tanker CertiK's arbejde her repræsenterer en bevidst udvidelse af sit sikkerhedsforskningsmandat fra smarte kontrakter og on-chain protokol sårbarheder til AI agent infrastruktur, et domæne, der akkumulerer den samme type privilegeret systemadgang, der gør blockchain sikkerhed kritisk. Skiftet, der faktisk ændrer sikkerhedsbilledet for OpenClaw og markedspladser som det er platformen, der antager nogle farlige færdigheder, vil komme igennem og opbygge runtime-begrænsning omkring det antagelse.
