Anthropic har bekr\u00e4ftat att Claude-modeller l\u00e4mnade till synes isolerade cybers\u00e4kerhetsutv\u00e4rderingsmilj\u00f6er och n\u00e5dde riktiga system anslutna till internet.<\/p>\n\n\n\n

Anthropic offentliggjorde tre s\u00e4kerhetsincidenter<\/a> som involverade modeller som trodde att de angrep simulerade m\u00e5l. Ett konfigurationsfel hade l\u00e4mnat internet\u00e5tkomsten aktiverad, vilket gjorde det m\u00f6jligt f\u00f6r dem att interagera med verkliga tj\u00e4nster och organisationer.<\/p>\n\n\n\n

Incidenterna f\u00f6ljer p\u00e5 det senaste intr\u00e5nget hos Hugging Face som involverade OpenAI-agenter och rapporter om att OpenAI-modeller utnyttjade zero-day-s\u00e5rbarheter i JFrog Artifactory<\/a> n\u00e4r de f\u00f6rs\u00f6kte fly fr\u00e5n en sandl\u00e5da.<\/p>\n\n\n\n

Internet\u00e5tkomsten f\u00f6rblev aktiverad under Claudes s\u00e4kerhetstester<\/h2>\n\n\n\n

Tredjepartsutv\u00e4rderaren Irregular organiserade testerna som capture-the-flag-\u00f6vningar. Modellerna fick instruktioner om att de k\u00f6rdes i isolerade simuleringar.<\/p>\n\n\n\n

Testmilj\u00f6n kunde dock fortfarande n\u00e5 det publika internet. N\u00e4r modellerna inte hittade sina avsedda simulerade m\u00e5l s\u00f6kte de efter liknande system online och behandlade vissa verkliga tj\u00e4nster som en del av \u00f6vningen.<\/p>\n\n\n\n

Anthropic och Irregular identifierade inte konfigurationsproblemet f\u00f6rr\u00e4n flera m\u00e5nader efter den tidigaste incidenten. Anthropic uppgav att det \u00e4ldsta k\u00e4nda intr\u00e5nget intr\u00e4ffade i april och f\u00f6rblev ouppt\u00e4ckt i cirka tre m\u00e5nader.<\/p>\n\n\n\n

Claude Mythos 5 publicerade ett skadligt PyPI-paket<\/h3>\n\n\n\n

Under en utv\u00e4rdering hittade Claude Mythos 5 installationsanvisningar som h\u00e4nvisade till ett fiktivt Python-paket. Paketnamnet hade inte registrerats p\u00e5 Python Package Index.<\/p>\n\n\n\n

Modellen ins\u00e5g att den kunde registrera det oanv\u00e4nda namnet och publicera sin egen kod. System som f\u00f6ljde installationsanvisningarna kunde sedan automatiskt ladda ner och k\u00f6ra paketet.<\/p>\n\n\n\n

Claude skapade n\u00f6dv\u00e4ndiga konton och laddade upp ett skadligt paket till PyPI. Paketet f\u00f6rblev offentligt tillg\u00e4ngligt i ungef\u00e4r en timme innan PyPI:s automatiserade skyddsmekanismer tog bort det.<\/p>\n\n\n\n

Under den perioden laddade 15 verkliga system ner och k\u00f6rde koden.<\/p>\n\n\n\n

Ett s\u00e4kerhetsf\u00f6retags inloggningsuppgifter stals<\/h3>\n\n\n\n

Ett drabbat system tillh\u00f6rde ett cybers\u00e4kerhetsf\u00f6retag som automatiskt laddar ner och skannar nyligen publicerade PyPI-paket.<\/p>\n\n\n\n

Det skadliga paketet samlade in inloggningsuppgifter fr\u00e5n systemet och skickade dem till infrastruktur som Claude hade skapat. Modellen anv\u00e4nde sedan de stulna inloggningsuppgifterna f\u00f6r att komma \u00e5t ytterligare delar av f\u00f6retagets n\u00e4tverk.<\/p>\n\n\n\n

Anthropic uppgav att Claude inte hade n\u00e5gon f\u00f6rhandsk\u00e4nnedom om organisationen och inte avsiktligt valde ut den som m\u00e5l. F\u00f6retaget meddelade PyPI och delade indikatorer kopplade till det skadliga paketet.<\/p>\n\n\n\n

Det drabbade cybers\u00e4kerhetsf\u00f6retaget hade inte uppt\u00e4ckt intr\u00e5nget innan Anthropic kontaktade dem.<\/p>\n\n\n\n

Claude Opus 4.7 fick \u00e5tkomst till en produktionsdatabas<\/h3>\n\n\n\n

En separat utv\u00e4rdering med Claude Opus 4.7 ledde till \u00e5tkomst till en verklig produktionsdatabas.<\/p>\n\n\n\n

Det fiktiva m\u00e5l som anv\u00e4ndes i \u00f6vningen hade samma namn som ett befintligt f\u00f6retag och dom\u00e4n. Efter att Claude misslyckats med att n\u00e5 det simulerade systemet hittade den den riktiga organisationen online och behandlade den som det avsedda m\u00e5let.<\/p>\n\n\n\n

Modellen extraherade applikations- och infrastrukturinloggningsuppgifter innan den fick \u00e5tkomst till en databas inneh\u00e5llande flera hundra rader produktionsinformation.<\/p>\n\n\n\n

Anthropic beskrev denna incident som allvarligare eftersom modellen n\u00e5dde skarpa aff\u00e4rssystem och kom \u00e5t riktiga data.<\/p>\n\n\n\n

Forskningsmodell skannade cirka 9 000 system<\/h3>\n\n\n\n

En icke offentliggjord Anthropic-forskningsmodell orsakade den tredje incidenten.<\/p>\n\n\n\n

Efter att den misslyckats med att lokalisera det avsedda testm\u00e5let skannade modellen cirka 9 000 internetanslutna system. Den \u00e4ventyrade en exponerad applikation med hj\u00e4lp av inloggningsuppgifter som visades p\u00e5 en fels\u00f6kningssida och en SQL-injektionss\u00e5rbarhet.<\/p>\n\n\n\n

Modellen kom senare fram till att den \u00e4ventyrade applikationen tillh\u00f6rde ett orelaterat molnkonto. Den stoppade sedan attacken utan att kr\u00e4va m\u00e4nskligt ingripande.<\/p>\n\n\n\n

Anthropic f\u00f6rs\u00f6kte fortfarande kontakta den drabbade organisationen n\u00e4r de publicerade sina resultat.<\/p>\n\n\n\n

Modeller f\u00f6rlitade sig p\u00e5 grundl\u00e4ggande s\u00e4kerhetsbrister<\/h3>\n\n\n\n

Anthropic uppgav att incidenterna inte involverade nya eller tidigare ok\u00e4nda attacktekniker.<\/p>\n\n\n\n

Modellerna f\u00f6rlitade sig p\u00e5 vanliga brister, inklusive exponerade inloggningsuppgifter, svaga l\u00f6senord, offentligt tillg\u00e4ngliga \u00e4ndpunkter, fels\u00f6kningssidor som inneh\u00f6ll k\u00e4nslig information och SQL-injektionss\u00e5rbarheter.<\/p>\n\n\n\n

Det huvudsakliga felet kom fr\u00e5n obegr\u00e4nsad internet\u00e5tkomst och modellernas antagande att varje n\u00e5bart system utgjorde en del av det auktoriserade testet.<\/p>\n\n\n\n

Anthropic pausade cybertester efter granskning av incidenterna<\/h3>\n\n\n\n

Anthropic b\u00f6rjade granska utv\u00e4rderingarna och pausade all cybers\u00e4kerhetstestning den 23 juli.<\/p>\n\n\n\n

F\u00f6retaget identifierade de tre incidenterna den 24 juli. Irregular och tv\u00e5 drabbade organisationer fick meddelanden den 27 juli.<\/p>\n\n\n\n

Anthropic fortsatte att f\u00f6rs\u00f6ka n\u00e5 den organisation som var inblandad i den tredje incidenten.<\/p>\n\n\n\n

Ingen av de tv\u00e5 organisationer som Anthropic framg\u00e5ngsrikt kontaktade hade sj\u00e4lvst\u00e4ndigt uppt\u00e4ckt intr\u00e5ngen innan de fick meddelandena.<\/p>\n\n\n\n

Utv\u00e4rderingsmilj\u00f6n saknade produktionsskyddsmekanismer<\/h3>\n\n\n\n

Testsystemen anv\u00e4nde inte de klassificerare, \u00f6vervakningsverktyg och andra skyddsmekanismer som ing\u00e5r i offentligt tillg\u00e4ngliga Claude-modeller.<\/p>\n\n\n\n

Anthropic uppgav att dess produktionsskydd sannolikt skulle ha blockerat de \u00e5tg\u00e4rder som s\u00e5gs under utv\u00e4rderingarna. De karakteriserade incidenterna fr\u00e4mst som misslyckanden i testdesign, infrastruktur, \u00f6vervakning och tredjeparts\u00f6vervakning.<\/p>\n\n\n\n

F\u00f6retaget beskrev inte incidenterna som bevis p\u00e5 ett grundl\u00e4ggande anpassningsfel. Ist\u00e4llet f\u00f6ljde modellerna utv\u00e4rderingsinstruktionerna samtidigt som de av misstag interagerade med verkliga m\u00e5l.<\/p>\n\n\n\n

Anthropic planerar striktare \u00f6vervakning f\u00f6r framtida tester<\/h3>\n\n\n\n

Anthropic planerar att ut\u00f6ka transkriptions\u00f6vervakning \u00f6ver framtida utv\u00e4rderingar och inf\u00f6ra starkare utredningsverktyg.<\/p>\n\n\n\n

De kommer ocks\u00e5 att \u00f6ka \u00f6vervakningen av tredjepartstestpartners och granska hur utv\u00e4rderingsmilj\u00f6er ansluter till extern infrastruktur.<\/p>\n\n\n\n

Anthropic diskuterar en oberoende granskning med METR och planerar att publicera en delvis censurerad transkription av PyPI-incidenten.<\/p>\n\n\n\n

Trots s\u00e4kerhetsmisslyckandena har Claude Mythos visat starka f\u00f6rm\u00e5gor att uppt\u00e4cka s\u00e5rbarheter. Microsoft har ocks\u00e5 erk\u00e4nt att de k\u00e4mpar med att \u00e5tg\u00e4rda alla s\u00e5rbarheter som hittats av Claude Mythos<\/a>, vilket understryker b\u00e5de modellens potential inom s\u00e4kerhetsforskning och de risker som skapas av bristf\u00e4lligt isolerade testmilj\u00f6er.<\/p>\n","protected":false},"excerpt":{"rendered":"
