Hi,

vorneweg: Ich nutze Windows 8 Pro und habe meinen PC 2 mal neuaufgesetzt. Das letzte mal am 25.12.2012.

Seit längerer Zeit beobachte ich mehrere DOS-Attacken in den Logs meines NETGEAR-Routers. Eigentlich nutze ich nur ein Programm, was solche Verbindungen rechtfertigt, Spotify. Ansonsten läuft Trillian, Steam oder auch mal WoW.

Der Log sieht folgendermaßen aus:

Zu bedenken ist, dass mein Bruder auch noch Spotify nutzt, aber solche Einträge nur vorkommen wenn auch mein PC gerade im LAN aktiv ist (Ab 3 Uhr nachts dann nicht mehr, daher auch keine Logs). Heute um ca. 17 Uhr habe ich mich wieder eingewählt, aber ohne Spotify. Bis 19 Uhr kamen dann keine Logs. Dann habe ich Spotify angemacht und kurz darauf gab es wieder einen PortScan von 58.218.199.250. Ob das wirklich mit Spotify zusammenhängt, kann ich nicht bestätigen und würde gerne wissen, was ich tun soll... Die IP wurde um ca. 17 Uhr von mir resettet, daher gibt es keinen Zusammenhang mit den Attacken von 3 Uhr nachts.

Was mir noch aufgefallen ist, ist dass WireShark folgende IP gemessen hat: 84.63.133.145

Diese hat zwar 3 mal versucht zuzugreifen, aber keine Antwort erhalten. Erst danach habe ich den Router reconnectet, sprich die IP der alten Session um 2-3 Uhr nachts war noch aktiv, war also mit dieser IP schonmal 15h davor in Trillian, Steam und Spotify. Anders kann ich mir diesen Zugriff nicht erklären, da ansonsten KEIN Programm aktiv war und keine anderen IP-Adressen zugegriffen haben,

nun nochmal was aufgetaucht:

Und, die Frage?
 
Ist das normal und wenn ja, wodurch wird es ausgelöst? Was ist, wenn gefährlich?

Ein DoS ist das nicht (einen richtigen DoS wuerdest du bei einer Heim-DSL-Verbindung daran merken dass du nicht ins Internet kommst...). Das ist irgendein Botrechner der IP-Ranges mit allen moeglichen Exploits durchprobiert. Port 80 und 443, eh klar, Webserver. Absolut kein Grund zur Panik, das ist vollkommen normal und ungefaehrlich.

MfG
 
Erstens: das ist kein DoS, das sind nichtmal 30 kleine IP-Pakete - die wirft deinRouter innerhalb von einem Augenzwinkern weg.

Der Traffic der etwa um 02:59:19 losgeht sieht mir stark nach Bittorrent aus (fast alle Pakete kommen von Endkunden Anschlüssen, alle von verschiedenen 5 stelligen Ports). Vermutlich einfach ein Fehlrouting.

Der Portscan kam aus China, Portscan auf Consumer IPs Europäischer User sind absolut normal, da hat wohl einfach ein Scriptkiddie nach offenen/verwundbaren Diensten gescannt

Es ist nicht gefährlich, der Router verwirft die Dinger einfach.
 
Zuletzt bearbeitet:
Ich nutze kein Bittorrent. Spotify nutzt aber p2p. Wie aber erwähnt hat das mein Bruder auch und diese Einträge kamen nur als auch ich im LAN war. Ich habe zwar GrabIt für Usenet aber das ist ja kein p2p und läuft nur bei Bedarf. Sind das wohl einige Fehllogs von zu vielen Zugriffen auf meine Lieder? Spotify shared tw. mit fast 20 versch. IPs in einem Time-Out. Aber auch nur, wenn man selbst in einer Session viele Songs anhört,
Danke und mfg
 
Seit ich nun Spotify nicht mehr nutze, kommen auch keinerlei DoS-Attacken mehr vor. Leider habe ich habe folgendes im Log festgestellt:

172.31.33.205 redirected vom Skypeport. Diese Adresse ist aber leider privat und kann nicht per WhoIs zugeordnet werden. Es ist zwar Skypeport und so aber naja...

hier kam eine ähnliche Nummer vor, ansonsten weiß ich nicht ob das legitim ist:
