Claude-modeller undkom f\u00f6rmodat isolerade cybers\u00e4kerhetsutv\u00e4rderingsmilj\u00f6er och n\u00e5dde verkliga internetanslutna system, bekr\u00e4ftar Anthropic.<\/p>\n\n\n\n

Anthropic avsl\u00f6jade tre s\u00e4kerhetsincidenter<\/a> med modeller som trodde att de attackerade simulerade m\u00e5l. Ett konfigurationsfel hade l\u00e4mnat internet\u00e5tkomsten aktiverad, vilket gjorde att de kunde interagera med riktiga tj\u00e4nster och organisationer.<\/p>\n\n\n\n

Incidenterna f\u00f6ljer p\u00e5 det senaste intr\u00e5nget hos Hugging Face med OpenAI-agenter och rapporter om att OpenAI-modeller utnyttjade nolldagars\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 verkade i isolerade simuleringar.<\/p>\n\n\n\n

Testmilj\u00f6n kunde dock fortfarande komma \u00e5t det offentliga internet. N\u00e4r modellerna misslyckades med att hitta de avsedda simulerade m\u00e5len, s\u00f6kte de efter liknande system online och behandlade vissa riktiga 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 sa 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 installationsinstruktioner som refererade 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 installationsinstruktionerna kunde sedan automatiskt ladda ner och k\u00f6ra paketet.<\/p>\n\n\n\n

Claude skapade de n\u00f6dv\u00e4ndiga kontona och laddade upp ett skadligt paket till PyPI. Paketet var offentligt tillg\u00e4ngligt i ungef\u00e4r en timme innan PyPIs automatiska skydd 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

S\u00e4kerhetsf\u00f6retags autentiseringsuppgifter stals<\/h3>\n\n\n\n

Ett p\u00e5verkat system tillh\u00f6rde ett cybers\u00e4kerhetsf\u00f6retag som automatiskt laddar ner och skannar nypublicerade PyPI-paket.<\/p>\n\n\n\n

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

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

Det p\u00e5verkade cybers\u00e4kerhetsf\u00f6retaget hade inte uppt\u00e4ckt intr\u00e5nget innan Anthropic kontaktade dem.<\/p>\n\n\n\n

Claude Opus 4.7 kom \u00e5t 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 delade namn med ett befintligt f\u00f6retag och dom\u00e4n. N\u00e4r Claude misslyckades med att n\u00e5 det simulerade systemet, hittade det den verkliga organisationen online och behandlade den som det avsedda m\u00e5let.<\/p>\n\n\n\n

Modellen extraherade applikations- och infrastrukturuppgifter innan den fick tillg\u00e5ng till en databas som inneh\u00f6ll flera hundra rader med produktionsinformation.<\/p>\n\n\n\n

Anthropic beskrev denna incident som allvarligare eftersom modellen n\u00e5dde levande aff\u00e4rssystem och fick tillg\u00e5ng till riktiga data.<\/p>\n\n\n\n

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

En \u00e4nnu inte sl\u00e4ppt forskningsmodell fr\u00e5n Anthropic orsakade den tredje incidenten.<\/p>\n\n\n\n

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

Modellen fastst\u00e4llde senare att den komprometterade applikationen tillh\u00f6rde ett icke-relaterat molnkonto. Den avbr\u00f6t sedan attacken utan att beh\u00f6va m\u00e4nsklig inblandning.<\/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

Modellerna f\u00f6rlitade sig p\u00e5 grundl\u00e4ggande s\u00e4kerhetssvagheter<\/h3>\n\n\n\n

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

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

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

Anthropic pausade cybertester efter att ha granskat incidenterna<\/h3>\n\n\n\n

Anthropic b\u00f6rjade granska utv\u00e4rderingarna och pausade alla cybers\u00e4kerhetstester 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 organisationen 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 komprometteringarna innan de fick meddelandena.<\/p>\n\n\n\n

Utv\u00e4rderingsmilj\u00f6n saknade produktionsskydd<\/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 sa att dess produktionsskydd sannolikt skulle ha blockerat de \u00e5tg\u00e4rder som s\u00e5gs under utv\u00e4rderingarna. F\u00f6retaget karakteriserade incidenterna fr\u00e4mst som brister 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 transkript\u00f6vervakning \u00f6ver framtida utv\u00e4rderingar och inf\u00f6ra starkare utredningsverktyg.<\/p>\n\n\n\n

Det 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 redigerad transkript av PyPI-incidenten.<\/p>\n\n\n\n

Trots s\u00e4kerhetsmisslyckandena har Claude Mythos visat stark f\u00f6rm\u00e5ga 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 belyser b\u00e5de modellens potential f\u00f6r s\u00e4kerhetsforskning och riskerna som skapas av d\u00e5ligt isolerade testmilj\u00f6er.<\/p>\n","protected":false},"excerpt":{"rendered":"
