Sicherheitsforscher von Apiiro haben Aktivit\u00e4ten von Angreifern identifiziert, die modifizierte Klone von Repositories verschiedener Projekte auf GitHub ver\u00f6ffentlichen. Diese Repositories enthalten kleine \u00c4nderungen, die auf b\u00f6swillige Handlungen abzielen. In der Regel wird das b\u00f6sartige Repository unter demselben Namen, jedoch an eine andere Organisation angeh\u00e4ngt (\u201egithub.org\/org1\/proj\u201c -> \u201egithub.org\/org2\/proj\u201c), oder es tr\u00e4gt einen leicht abweichenden Namen (Typo-Squatting), in der Annahme, dass das Opfer die Unterschiede nicht bemerkt und den Code mit den b\u00f6sartigen \u00c4nderungen nutzt. Um Benutzer anzulocken, werden Links zu den b\u00f6sartigen Repositories aktiv in verschiedenen sozialen Netzwerken, Foren und Chats geteilt. <\/p>\n
Es wird berichtet, dass \u00fcber 100.000 solcher Repositories identifiziert wurden, jedoch vermuten die Forscher, dass die Gesamtzahl der ver\u00f6ffentlichten Repositories mit b\u00f6sartigen \u00c4nderungen in die Millionen gehen k\u00f6nnte, da der \u00fcberwiegende Teil der automatisch erstellten Repositories von GitHub innerhalb weniger Stunden nach ihrer Ver\u00f6ffentlichung gel\u00f6scht wird. Unter den Masken, die verwendet werden k\u00f6nnen, um das Vorhandensein b\u00f6sartiger Einf\u00fcgungen in hochgeladenen Repositories zu erkennen, werden folgende genannt: exec(Fernet exec(requests exec(__import exec(bytes exec(\"\"\"\nimport exec(compile __import__(\"builtins\").exec( <\/p>\n
Der angeh\u00e4ngte sch\u00e4dliche Code ist eine modifizierte Version von BlackCap-Grabber, die nach dem Start nach sensiblen Daten sucht, wie z.B. Kontodaten, Token, im Browser gespeicherte Passw\u00f6rter und Cookies, und diese an Server<\/a> die Angreifer sendet. Der sch\u00e4dliche Code unterst\u00fctzt au\u00dferdem das Ersetzen von Kryptow\u00e4hrungsadressen, die \u00fcber die Zwischenablage \u00fcbertragen werden, kann Screenshots erstellen und Befehle von einem Command-and-Control-Server (C&C) annehmen.
