Claude-modeller l\u00e4mnade 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 avsl\u00f6jade tre s\u00e4kerhetsincidenter<\/a> som involverade modeller som trodde att de attackerade simulerade m\u00e5l. Ett konfigurationsfel hade l\u00e4mnat internet\u00e5tkomst aktiverat, 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 p\u00e5 Hugging Face som involverade OpenAI-agenter och rapporter om att OpenAI-modeller utnyttjade nolldagss\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

Den tredjepartsutv\u00e4rderare Irregular organiserade testerna som capture-the-flag-\u00f6vningar. Modellerna fick instruktioner som angav att de opererade inuti isolerade simuleringar.<\/p>\n\n\n\n

Testmilj\u00f6n hade dock fortfarande tillg\u00e5ng till 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 den \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 lediga namnet och publicera sin egen kod. System som f\u00f6ljde installationsinstruktionerna kunde sedan automatiskt ladda ner och exekvera 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 skydd tog bort det.<\/p>\n\n\n\n

Under den tiden laddade 15 verkliga system ner och exekverade koden.<\/p>\n\n\n\n

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 nypublicerade 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 uppgifterna f\u00f6r att f\u00e5 tillg\u00e5ng till ytterligare delar av f\u00f6retagets n\u00e4tverk.<\/p>\n\n\n\n

Anthropic uppgav att Claude inte hade n\u00e5gon f\u00f6rhandskunskap 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 det.<\/p>\n\n\n\n

Claude Opus 4.7 fick tillg\u00e5ng till en produktionsdatabas<\/h3>\n\n\n\n

En separat utv\u00e4rdering med Claude Opus 4.7 ledde till tillg\u00e5ng till en verklig produktionsdatabas.<\/p>\n\n\n\n

Det fiktiva m\u00e5let som anv\u00e4ndes i \u00f6vningen delade sitt 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 infrastrukturuppgifter innan den fick tillg\u00e5ng 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

FoU-modell 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 misslyckades med att hitta det avsedda testm\u00e5let skannade modellen omkring 9 000 internetanslutna system. Den komprometterade en exponerad applikation genom att anv\u00e4nda inloggningsuppgifter 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 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 drabbade organisationen n\u00e4r de publicerade sina resultat.<\/p>\n\n\n\n

Modeller f\u00f6rlitade sig p\u00e5 grundl\u00e4ggande s\u00e4kerhetssvagheter<\/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 svagheter, inklusive exponerade inloggningsuppgifter, svaga l\u00f6senord, publikt tillg\u00e4ngliga slutpunkter, fels\u00f6kningssidor inneh\u00e5llande k\u00e4nslig information och SQL-injektionss\u00e5rbarheter.<\/p>\n\n\n\n

Det huvudsakliga misstaget 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 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 organisationen 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 mottog 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 skydd 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. Det karakteriserade incidenterna fr\u00e4mst som brister i testdesign, infrastruktur, \u00f6vervakning och tredjeparts\u00f6versyn.<\/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 utskrifts\u00f6vervakningen \u00f6ver framtida utv\u00e4rderingar och inf\u00f6ra starkare utredningsverktyg.<\/p>\n\n\n\n

De kommer ocks\u00e5 att \u00f6ka \u00f6vervakningen av tredjepartspartners 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 utskrift av PyPI-incidenten.<\/p>\n\n\n\n

Trots s\u00e4kerhetsbristerna 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 buggar som hittats av Claude Mythos<\/a>, vilket understryker b\u00e5de modellens potential f\u00f6r s\u00e4kerhetsforskning och riskerna som skapas av d\u00e5ligt isolerade testmilj\u00f6er.<\/p>\n","protected":false},"excerpt":{"rendered":"
