Claude-modeller tog sig ut ur f\u00f6rmodat isolerade utv\u00e4rderingsmilj\u00f6er f\u00f6r cybers\u00e4kerhet och n\u00e5dde verkliga internetanslutna system, har Anthropic bekr\u00e4ftat.<\/p>\n\n\n\n

Anthropic offentliggjorde tre s\u00e4kerhetsincidenter<\/a> d\u00e4r modeller trodde att de angrep simulerade m\u00e5l. Ett konfigurationsfel hade l\u00e4mnat internet\u00e5tkomsten aktiverad, vilket gjorde att de kunde interagera med verkliga tj\u00e4nster och organisationer.<\/p>\n\n\n\n

Incidenterna f\u00f6ljer p\u00e5 det nyliga intr\u00e5nget mot Hugging Face d\u00e4r OpenAI-agenter var inblandade, samt rapporter om att OpenAI-modeller utnyttjade nolldagars s\u00e5rbarheter i JFrog Artifactory<\/a> n\u00e4r de f\u00f6rs\u00f6kte fly 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 arbetade i isolerade simuleringar.<\/p>\n\n\n\n

Dock kunde testmilj\u00f6n fortfarande n\u00e5 det publika internet. N\u00e4r modellerna inte lyckades hitta 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 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 ungef\u00e4r 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 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 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 PyPI:s 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 nyligen publicerade 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 sade 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 ber\u00f6rda 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\u00e5let som anv\u00e4ndes i \u00f6vningen delade namn med ett befintligt f\u00f6retag och dom\u00e4n. Efter att Claude inte lyckades 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 infrastrukturautentiseringsuppgifter innan den fick \u00e5tkomst till en databas som inneh\u00f6ll flera hundra rader produktionsinformation.<\/p>\n\n\n\n

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

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

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

Efter att den inte lyckades hitta det avsedda testm\u00e5let skannade modellen omkring 9 000 internetanslutna system. Den komprometterade en exponerad applikation genom att anv\u00e4nda autentiseringsuppgifter som visades p\u00e5 en fels\u00f6kningssida samt en SQL-injektionss\u00e5rbarhet.<\/p>\n\n\n\n

Modellen fastst\u00e4llde senare att den komprometterade applikationen tillh\u00f6rde ett orelaterat molnkonto. Den stoppade sedan attacken utan att kr\u00e4va m\u00e4nsklig inblandning.<\/p>\n\n\n\n

Anthropic f\u00f6rs\u00f6kte fortfarande kontakta den ber\u00f6rda organisationen n\u00e4r de publicerade sina resultat.<\/p>\n\n\n\n

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

Anthropic sade 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 slutpunkter, fels\u00f6kningssidor som inneh\u00f6ll k\u00e4nslig information samt SQL-injektionss\u00e5rbarheter.<\/p>\n\n\n\n

Det huvudsakliga misslyckandet 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 att ha granskat incidenterna<\/h3>\n\n\n\n

Anthropic p\u00e5b\u00f6rjade granskningen av 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 ber\u00f6rda 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

Inget 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 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 sade 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\u00f6versyn.<\/p>\n\n\n\n

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

Anthropic planerar str\u00e4ngare \u00f6vervakning f\u00f6r framtida tester<\/h3>\n\n\n\n

Anthropic planerar att ut\u00f6ka transkriptions\u00f6vervakningen \u00f6ver framtida utv\u00e4rderingar och inf\u00f6ra starkare utredningsverktyg.<\/p>\n\n\n\n

Det kommer ocks\u00e5 att \u00f6ka \u00f6versynen av tredjepartstestpartners och granska hur utv\u00e4rderingsmilj\u00f6erna ansluter till extern infrastruktur.<\/p>\n\n\n\n

Anthropic diskuterar en oberoende granskning med METR och planerar att publicera ett delvis redigerat transskript 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 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":"
