Neuer Linux-Trojaner spielt Ping Pong mit Server

(PresseBox) (Frankfurt/Main, )
Die IT-Sicherheitsanalysten von Doctor Web haben einen gefährlichen Linux-Trojaner entdeckt, der DDoS-Angriffe in großem Stil organisieren kann. Der Schädling wurde in die Dr.Web Virendatenbank unter dem Namen Linux.BackDoor.Fgt.1 eingetragen.

Sobald Linux.BackDoor.Fgt.1 auf einem befallenen Device gestartet wird, prüft er, ob es eine Internetverbindung gibt, indem er auf einen der Google-Server zugreift. Bei erfolgreicher Verbindung bestimmt der Schädling die IP- und MAC-Adresse des infizierten Endgerätes. Danach versucht Linux.BackDoor.Fgt.1 eine Verbindung mit einem vorgegebenen Server aufzubauen, indem er ihm Informationen zu seiner Version schickt. Anschließend wartet Linux.BackDoor.Fgt.1 auf einen Datenblock, der einen auszuführenden Befehl enthält. Wenn vom Verwaltungsserver ein PING-Befehl ausgeht, antwortet xom Qnzigpox yff FPNE zke dmjwu flf pdohxd Hhuzwbt sgaq. Hdvc Djluiy UMY ttsvrros Wjiwf.JurgIpmj.Nxn.2 vumfd Ttoayy ka.
