ZeroDay und noch was komisches
 
Guten Tag, seit kurzem scheint mein Server sehr beliebt zu sein und NGINX spuckt mir sehr verdächtige LOGS aus.

Zur Sicherheit hab ich mal gleich meinen Server runtergefahren aber naja ich würde jetzt gerne herausfinden ob die feindlichen Angriffe geglückt sind oder nicht :heulen: Aus manchen Zeilen in den Logs werde ich nämlich nicht schlau.

Ich würde gerne z.B den Code von gerne 180.97.106.37 decodieren. Ich weiß nur peinlicherweiße nicht in was der Code codiert wurde xd

Auf dem Server läuf Debian 7, nginx 1.2.1 und PHP 5.6.24-1~dotdeb+7.1 (fpm-fcgi) (built: Jul 21 2016 23:28:37)

Zero-Day sollte mir also nichts anhaben aber beim Rest :/?

Das sieht besonders unschön aus.

Da sind Angriffsversuche.
Ganz einfacher Hinweis: mach dich zB mit der /etc/hosts.deny vertraut
Dienste, die das über diese Datei nicht regeln können musst du über deren Konfigdatei entsprechend einschränken. Oder hast du chinesische Kunden als Zielgruppe?

Wenn du diesen Host allein dastehend hast, d.h. ohne "externe" Firewall (reverse proxy), solltest du darüber nachdenken das noch nachzuholen. Oder versuch dein Glück mit NFtables.

Erstmal danke für die Antwort :)

Mittlerweile hab ich übrigens herausgefunden wozu fast alle Angriffsversuche gehören.

Siehe hier: https://debianforum.de/forum/viewtopic.php?f=8&t=161953

Hab mir mittlerweile aus der Situation einen Spaß gemacht und mir ein C++ Programm geschrieben das herausfindet aus welchen IP Bereichen die meisten Angriffe stammen, sofern eine Datei mit verschiedenen IP vorhanden ist.

cosinus 07.09.2016 08:45

Ok wenn du meinst :D
Ich würde ja die Zugriffe einschränken. So mach ich das zB mit denyhosts oder fail2ban um nach einer bestimmten Anzahl von fehlgeschlagenen SSH-Logins automatisch die IP des Angreifers in die /etc/hosts.deny einzutragen

Mit einem IPS wie fail2ban soll man auch Angriffsmuster auf andere Dienste als nur SSH erkennen können. Ich weiß abernicht, ob er auch deinen nginx unterstützt. nginx soll ja auch keine .htaccess files verarbeiten :wtf:
