Claude-modeller slap ud af angiveligt isolerede cybersikkerheds-evalueringsmilj\u00f8er og n\u00e5ede reelle internetvendte systemer, bekr\u00e6fter Anthropic.<\/p>\n\n\n\n

Anthropic offentliggjorde tre sikkerhedsh\u00e6ndelser<\/a>, der involverede modeller, der troede, de angreb simulerede m\u00e5l. En konfigurationsfejl havde efterladt internetadgangen aktiveret, hvilket tillod dem at interagere med reelle tjenester og organisationer.<\/p>\n\n\n\n

H\u00e6ndelserne f\u00f8lger det nylige Hugging Face-brud, der involverede OpenAI-agenter, og rapporter om, at OpenAI-modeller udnyttede JFrog Artifactory zero-day-s\u00e5rbarheder<\/a>, mens de fors\u00f8gte at undslippe en sandkasse.<\/p>\n\n\n\n

Internetadgang forblev aktiveret under Claudes sikkerhedstests<\/h2>\n\n\n\n

Tredjeparts evaluatoren Irregular organiserede testene som capture the flag-\u00f8velser. Modellerne modtog instruktioner, der sagde, at de opererede inde i isolerede simulationer.<\/p>\n\n\n\n

Dog kunne testmilj\u00f8et stadig tilg\u00e5 det offentlige internet. Da modellerne ikke kunne finde deres tilt\u00e6nkte simulerede m\u00e5l, s\u00f8gte de efter lignende systemer online og behandlede nogle reelle tjenester som en del af \u00f8velsen.<\/p>\n\n\n\n

Anthropic og Irregular identificerede ikke konfigurationsproblemet f\u00f8r m\u00e5neder efter den tidligste h\u00e6ndelse. Anthropic sagde, at det \u00e6ldste kendte brud fandt sted i april og forblev uopdaget i omkring tre m\u00e5neder.<\/p>\n\n\n\n

Claude Mythos 5 udgav en ondsindet PyPI-pakke<\/h3>\n\n\n\n

Under en evaluering fandt Claude Mythos 5 ops\u00e6tningsinstruktioner, der henviste til en fiktiv Python-pakke. Pakkenavnet var ikke registreret p\u00e5 Python Package Index.<\/p>\n\n\n\n

Modellen inds\u00e5, at den kunne registrere det ubrugte navn og udgive sin egen kode. Systemer, der fulgte ops\u00e6tningsinstruktionerne, kunne derefter automatisk downloade og eksekvere pakken.<\/p>\n\n\n\n

Claude oprettede de n\u00f8dvendige konti og uploadede en ondsindet pakke til PyPI. Pakken forblev offentligt tilg\u00e6ngelig i cirka en time, f\u00f8r PyPIs automatiserede beskyttelser fjernede den.<\/p>\n\n\n\n

I den periode downloadede og eksekverede 15 reelle systemer koden.<\/p>\n\n\n\n

Sikkerhedsfirmas loginoplysninger blev stj\u00e5let<\/h3>\n\n\n\n

Et af de ber\u00f8rte systemer tilh\u00f8rte et cybersikkerhedsfirma, der automatisk downloader og scanner nyligt udgivne PyPI-pakker.<\/p>\n\n\n\n

Den ondsindede pakke indsamlede loginoplysninger fra systemet og sendte dem til infrastruktur, som Claude havde oprettet. Modellen brugte derefter de stj\u00e5lne loginoplysninger til at f\u00e5 adgang til yderligere dele af firmaets netv\u00e6rk.<\/p>\n\n\n\n

Anthropic sagde, at Claude ikke havde nogen forudg\u00e5ende viden om organisationen og ikke bevidst valgte den som m\u00e5l. Virksomheden underrettede PyPI og delte indikatorer forbundet med den ondsindede pakke.<\/p>\n\n\n\n

Det ber\u00f8rte cybersikkerhedsfirma havde ikke opdaget indtr\u00e6ngningen, f\u00f8r Anthropic kontaktede det.<\/p>\n\n\n\n

Claude Opus 4.7 fik adgang til en produktionsdatabase<\/h3>\n\n\n\n

En separat evaluering, der involverede Claude Opus 4.7, resulterede i adgang til en reel produktionsdatabase.<\/p>\n\n\n\n

Det fiktive m\u00e5l, der blev brugt i \u00f8velsen, delte navn med en eksisterende virksomhed og dom\u00e6ne. Efter at Claude ikke kunne n\u00e5 det simulerede system, fandt den den reelle organisation online og behandlede den som det tilt\u00e6nkte m\u00e5l.<\/p>\n\n\n\n

Modellen udtrak applikations- og infrastrukturadgangsoplysninger, f\u00f8r den fik adgang til en database, der indeholdt adskillige hundrede r\u00e6kker af produktionsinformation.<\/p>\n\n\n\n

Anthropic beskrev denne h\u00e6ndelse som mere alvorlig, fordi modellen n\u00e5ede live forretningssystemer og fik adgang til reelle data.<\/p>\n\n\n\n

Forskningsmodel scannede omkring 9.000 systemer<\/h3>\n\n\n\n

En ikke-udgivet Anthropic-forskningsmodel for\u00e5rsagede den tredje h\u00e6ndelse.<\/p>\n\n\n\n

Efter at den ikke kunne finde det tilt\u00e6nkte testm\u00e5l, scannede modellen omkring 9.000 internetforbundne systemer. Den kompromitterede en eksponeret applikation ved hj\u00e6lp af loginoplysninger vist p\u00e5 en debug-side og en SQL-injektionss\u00e5rbarhed.<\/p>\n\n\n\n

Modellen fastslog senere, at den kompromitterede applikation tilh\u00f8rte en uafh\u00e6ngig cloud-konto. Den stoppede derefter angrebet uden at kr\u00e6ve menneskelig indgriben.<\/p>\n\n\n\n

Anthropic fors\u00f8gte stadig at kontakte den ber\u00f8rte organisation, da det offentliggjorde sine resultater.<\/p>\n\n\n\n

Modeller stolede p\u00e5 grundl\u00e6ggende sikkerhedssvagheder<\/h3>\n\n\n\n

Anthropic sagde, at h\u00e6ndelserne ikke involverede nye eller tidligere ukendte angrebsteknikker.<\/p>\n\n\n\n

Modellerne stolede p\u00e5 almindelige svagheder, herunder eksponerede loginoplysninger, svage adgangskoder, offentligt tilg\u00e6ngelige endepunkter, debug-sider, der indeholdt f\u00f8lsomme oplysninger, og SQL-injektionss\u00e5rbarheder.<\/p>\n\n\n\n

Den prim\u00e6re fejl kom fra ubegr\u00e6nset internetadgang og modellernes antagelse om, at ethvert tilg\u00e6ngeligt system var en del af den autoriserede test.<\/p>\n\n\n\n

Anthropic satte cybersikkerhedstests p\u00e5 pause efter gennemgang af h\u00e6ndelserne<\/h3>\n\n\n\n

Anthropic begyndte at gennemg\u00e5 evalueringerne og satte alle cybersikkerhedstests p\u00e5 pause den 23. juli.<\/p>\n\n\n\n

Virksomheden identificerede de tre h\u00e6ndelser den 24. juli. Irregular og to ber\u00f8rte organisationer modtog underretninger den 27. juli.<\/p>\n\n\n\n

Anthropic fortsatte med at fors\u00f8ge at kontakte den organisation, der var involveret i den tredje h\u00e6ndelse.<\/p>\n\n\n\n

Ingen af de to organisationer, som Anthropic med held kontaktede, havde uafh\u00e6ngigt opdaget kompromitteringerne, f\u00f8r de modtog underretningerne.<\/p>\n\n\n\n

Evalueringsmilj\u00f8 manglede produktionsbeskyttelser<\/h3>\n\n\n\n

Testsystemerne brugte ikke de klassifikatorer, overv\u00e5gningsv\u00e6rkt\u00f8jer og andre beskyttelser, der er inkluderet i offentligt tilg\u00e6ngelige Claude-modeller.<\/p>\n\n\n\n

Anthropic sagde, at dets produktionsbeskyttelser sandsynligvis ville have blokeret de handlinger, der blev set under evalueringerne. Det karakteriserede h\u00e6ndelserne prim\u00e6rt som fejl i testdesign, infrastruktur, overv\u00e5gning og tredjeparts tilsyn.<\/p>\n\n\n\n

Virksomheden beskrev ikke h\u00e6ndelserne som bevis p\u00e5 en grundl\u00e6ggende alignment-fejl. I stedet fulgte modellerne evalueringsinstruktionerne, mens de fejlagtigt interagerede med reelle m\u00e5l.<\/p>\n\n\n\n

Anthropic planl\u00e6gger strengere overv\u00e5gning til fremtidige tests<\/h3>\n\n\n\n

Anthropic planl\u00e6gger at udvide transskriptionoverv\u00e5gning p\u00e5 tv\u00e6rs af fremtidige evalueringer og indf\u00f8re st\u00e6rkere unders\u00f8gelsesv\u00e6rkt\u00f8jer.<\/p>\n\n\n\n

Det vil ogs\u00e5 \u00f8ge tilsynet med tredjeparts testpartnere og gennemg\u00e5, hvordan evalueringsmilj\u00f8er forbinder til ekstern infrastruktur.<\/p>\n\n\n\n

Anthropic diskuterer en uafh\u00e6ngig gennemgang med METR og planl\u00e6gger at offentligg\u00f8re en delvist sl\u00f8ret transskription af PyPI-h\u00e6ndelsen.<\/p>\n\n\n\n

P\u00e5 trods af sikkerhedsfejlene har Claude Mythos demonstreret st\u00e6rke evner til s\u00e5rbarhedsdetektion. Microsoft har ogs\u00e5 erkendt, at det k\u00e6mper med at rette alle de s\u00e5rbarheder, som Claude Mythos finder<\/a>, hvilket fremh\u00e6ver b\u00e5de modellens sikkerhedsforskningspotentiale og de risici, der skabes af d\u00e5rligt isolerede testmilj\u00f8er.<\/p>\n","protected":false},"excerpt":{"rendered":"
