Utvecklarna av Packj-plattformen, som analyserar s\u00e4kerheten av bibliotek, har publicerat ett \u00f6ppet kommandoradsverktyg som m\u00f6jligg\u00f6r uppt\u00e4ckten av riskfyllda konstruktioner i paket som kan kopplas till genomf\u00f6randet av skadlig aktivitet eller f\u00f6rekomsten av s\u00e5rbarheter som anv\u00e4nds f\u00f6r att attackera projekt som anv\u00e4nder de aktuella paketen (\"supply chain\"). Kontrollen av paket p\u00e5 Python och JavaScript som \u00e4r placerade i katalogerna PyPi och NPM st\u00f6ds (den h\u00e4r m\u00e5naden planerar de ocks\u00e5 att l\u00e4gga till st\u00f6d f\u00f6r Ruby och RubyGems). Verktygskoden \u00e4r skriven i Python och distribueras under AGPLv3-licensen. <\/p>\n

I analysen av 330 000 paket med det f\u00f6reslagna verktyget i PyPi-repositories identifierades 42 skadliga paket med bakd\u00f6rrar och 2,4 tusen riskabla paket. I unders\u00f6kningsprocessen utf\u00f6rs en statisk kodanalys f\u00f6r att identifiera API-egenskaper och bed\u00f6ma f\u00f6rekomsten av k\u00e4nda s\u00e5rbarheter, som \u00e4r noterade i OSV-databasen. MalOSS-paketet anv\u00e4nds f\u00f6r API-analys. Paketens kod analyseras f\u00f6r att uppt\u00e4cka typiska m\u00f6nster som vanligtvis anv\u00e4nds i skadlig programvara. M\u00f6nstren har f\u00f6rberetts utifr\u00e5n studier av 651 paket med verifierad skadlig aktivitet. <\/p>\n

Det uppt\u00e4ckts ocks\u00e5 attribut och metadata som \u00f6kar risken f\u00f6r oavsiktlig anv\u00e4ndning, s\u00e5som exekvering av block genom \"eval\" eller \"exec\", skapande av ny kod under k\u00f6rning, anv\u00e4ndning av tekniker f\u00f6r f\u00f6rvirring och koddoldhet (obfuscated), manipulation av milj\u00f6variabler, oavsiktlig \u00e5tkomst till filer, anrop av n\u00e4tverksresurser i installationsscript (setup.py), anv\u00e4ndning av type squatting (tilldelning av namn som liknar namnen p\u00e5 popul\u00e4ra bibliotek), uppt\u00e4ckte f\u00f6r\u00e5ldrade och \u00f6vergivna projekt, angivelse av icke-existerande e-postadresser och webbplatser, samt avsaknad av offentligt kodf\u00f6rr\u00e5d. <\/p>\n

Det kan ocks\u00e5 noteras att andra s\u00e4kerhetsforskare har identifierat fem skadliga paket i PyPi-repositoriet som skickade server<\/a> inneh\u00e5llet i milj\u00f6variabler med avsikt att stj\u00e4la tokens till AWS och system f\u00f6r kontinuerlig integration: loglib-modules (presenterades som moduler till det legitima biblioteket loglib), pyg-modules, pygrata och pygrata-utils (presenterades som till\u00e4gg till det legitima biblioteket pyg) samt hkg-sol-utils. <\/ul>\n
