Claude-modeller rymde fr\u00e5n antaget 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> som involverade modeller som trodde att de angrep simulerade m\u00e5l. Ett konfigurationsfel hade l\u00e4mnat internet\u00e5tkomst aktiverat, vilket gjorde att de kunde interagera med riktiga tj\u00e4nster och organisationer.<\/p>\n\n\n\n

Incidenterna f\u00f6ljer efter det nyligen intr\u00e4ffade intr\u00e5nget p\u00e5 Hugging Face som involverade OpenAI-agenter och rapporter om att OpenAI-modeller utnyttjade nolldagars-s\u00e5rbarheter i JFrog Artifactory<\/a> n\u00e4r de f\u00f6rs\u00f6kte fly en sandbox.<\/p>\n\n\n\n

Internet\u00e5tkomsten var fortsatt aktiverad under Claudes s\u00e4kerhetstester<\/h2>\n\n\n\n

Den tredjepartsbaserade utv\u00e4rderaren Irregular organiserade testerna som capture-the-flag-\u00f6vningar. Modellerna fick instruktioner som angav att de arbetade i isolerade simuleringar.<\/p>\n\n\n\n

Testmilj\u00f6n kunde dock fortfarande komma \u00e5t det publika internet. N\u00e4r modellerna inte lyckades hitta sina avsedda simulerade m\u00e5l s\u00f6kte de efter liknande system online och behandlade en del 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 refererade till ett fiktivt Python-paket. Paketnamnet var inte registrerat 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 l\u00e5g offentligt tillg\u00e4ngligt i ungef\u00e4r en timme innan PyPI:s automatiska skydd tog bort det.<\/p>\n\n\n\n

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

Inloggningsuppgifter till ett s\u00e4kerhetsf\u00f6retag stals<\/h3>\n\n\n\n

Ett av de drabbade systemen 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 komma \u00e5t ytterligare delar av f\u00f6retagets n\u00e4tverk.<\/p>\n\n\n\n

Anthropic uppgav att Claude inte hade n\u00e5gon tidigare k\u00e4nnedom om organisationen och inte medvetet valde ut den som m\u00e5ltavla. F\u00f6retaget meddelade PyPI och delade med sig av 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 resulterade i \u00e5tkomst till en verklig produktionsdatabas.<\/p>\n\n\n\n

Det p\u00e5hittade m\u00e5let som anv\u00e4ndes i \u00f6vningen delade namn med ett befintligt f\u00f6retag och dom\u00e4n. Efter att Claude misslyckades med att n\u00e5 det simulerade systemet hittade modellen den riktiga organisationen online och behandlade den som det avsedda m\u00e5let.<\/p>\n\n\n\n

Modellen extraherade applikations- och infrastrukturreferenser 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 ungef\u00e4r 9 000 system<\/h3>\n\n\n\n

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

Efter att den inte lyckades hitta det avsedda testm\u00e5let skannade modellen ungef\u00e4r 9 000 internetanslutna system. Den komprometterade en exponerad applikation med hj\u00e4lp av referenser 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\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

Modellerna 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 svagheter, inklusive exponerade referenser, svaga l\u00f6senord, publikt \u00e5tkomliga slutpunkter, fels\u00f6kningssidor som inneh\u00f6ll k\u00e4nslig information och 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 ingick i det auktoriserade testet.<\/p>\n\n\n\n

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

Anthropic p\u00e5b\u00f6rjade en granskning 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 drabbade organisationer meddelades 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 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 uppgav att deras produktionsskydd sannolikt skulle ha blockerat de \u00e5tg\u00e4rder som observerades under utv\u00e4rderingarna. Man beskrev incidenterna fr\u00e4mst som misslyckanden i testutformning, infrastruktur, \u00f6vervakning och tredjepartstillsyn.<\/p>\n\n\n\n

F\u00f6retaget beskrev inte incidenterna som bevis p\u00e5 ett grundl\u00e4ggande alignment-fel. 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\u00f6vervakningen i framtida utv\u00e4rderingar och inf\u00f6ra starkare utredningsverktyg.<\/p>\n\n\n\n

Man kommer ocks\u00e5 att \u00f6ka tillsynen av tredjeparts-testpartners och granska hur utv\u00e4rderingsmilj\u00f6er kopplas till extern infrastruktur.<\/p>\n\n\n\n

Anthropic diskuterar en oberoende granskning med METR och planerar att publicera ett delvis maskerat transkript 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 s\u00e5rbarheter som hittas av Claude Mythos<\/a>, vilket understryker b\u00e5de modellens potential inom s\u00e4kerhetsforskning och de risker som skapas av d\u00e5ligt isolerade testmilj\u00f6er.<\/p>\n","protected":false},"excerpt":{"rendered":"
