Utviklerne av Packj-plattformen, som analyserer sikkerheten til biblioteker, har publisert et \u00e5pent kommandolinjeverkt\u00f8y som identifiserer risikable konstruksjoner i pakker som kan v\u00e6re knyttet til implementering av ondsinnet aktivitet eller tilstedev\u00e6relse av s\u00e5rbarheter som brukes til \u00e5 angripe prosjekter som benytter de aktuelle pakkene (\u00bbsupply chain\u00ab). Pakker p\u00e5 spr\u00e5kene Python og JavaScript som er plassert i katalogene PyPi og NPM st\u00f8ttes, og det planlegges ogs\u00e5 \u00e5 legge til st\u00f8tte for Ruby og RubyGems denne m\u00e5neden. Verkt\u00f8yets kode er skrevet i Python og distribueres under AGPLv3-lisensen. <\/p>\n

I l\u00f8pet av analysen av 330 000 pakker ved hjelp av det foresl\u00e5tte verkt\u00f8yet i PyPi-repoet, ble 42 ondsinnede pakker med bakd\u00f8rer og 2 400 risikable pakker identifisert. Under inspeksjonen utf\u00f8res en statisk kodeanalyse for \u00e5 identifisere API-funksjoner og vurdere tilstedev\u00e6relsen av kjente s\u00e5rbarheter, merket i OSV-databasen. For API-analyse brukes pakken MalOSS. Koden til pakkene analyseres for typiske m\u00f8nstre som ofte brukes i ondsinnet programvare. M\u00f8nstrene er utarbeidet basert p\u00e5 studier av 651 pakker med bekreftet ondsinnet aktivitet. <\/p>\n

Det identifiseres ogs\u00e5 attributter og metadata som kan f\u00f8re til \u00f8kt risiko for utilsiktet bruk, som utf\u00f8relse av blokker via \u00bbeval\u00ab eller \u00bbexec\u00ab, generering av ny kode under kj\u00f8ring, bruk av teknikker for koding og skjulingsmetoder (obfuscated), manipulasjon med milj\u00f8variabler, utilsiktet tilgang til filer, tilgang til nettverksressurser i installasjonsscenarier (setup.py), bruk av type-squatting (navngiving av variabler som ligner p\u00e5 navnene til popul\u00e6re biblioteker), identifisering av utdaterte og forlatte prosjekter, angivelse av ikke-befinnende e-postadresser og nettsteder, samt frav\u00e6r av offentlig kode-repositorium. <\/p>\n

I tillegg kan det nevnes at andre sikkerhetsforskere har identifisert fem ondsinnede pakker i PyPi-repoet som sendte ut server<\/a> innholdet i milj\u00f8variablene med det form\u00e5l \u00e5 stjele tokens til AWS og systemer for kontinuerlig integrasjon: loglib-modules (presentert som moduler til det legitime biblioteket loglib), pyg-modules, pygrata og pygrata-utils (presentert som tillegg til det legitime biblioteket pyg) og hkg-sol-utils. <\/ul>\n
