Eine Sicherheitsl\u00fccke in Ivantis Connect Secure (ICS), einer VPN-Software, wurde im Januar entdeckt und von Angreifern ausgenutzt. Die US-Beh\u00f6rde CISA fand auf betroffenen Systemen die Malware \u201eResurge\u201c, eine Weiterentwicklung der Schadsoftware \u201eSpawn-Chimera\u201c. Sie \u00fcbersteht Neustarts, kann Webshells einrichten und Integrit\u00e4tspr\u00fcfungen umgehen.<\/p>\n

Die Malware besteht aus mehreren Komponenten, darunter ein SSH-Tunnel zu Command-and-Control-Servern, ein Tool zur Manipulation von Ivanti-Logs sowie eine Sammlung von BusyBox-Applets. Diese erm\u00f6glichen das Extrahieren und Nachladen weiterer Schadsoftware. CISA liefert Erkennungsregeln und Empfehlungen zur Erkennung infizierter Systeme. Ivanti hat Software-Updates bereitgestellt, um die Schwachstelle zu schlie\u00dfen.<\/p>\n
