Hi,
man liest ja recht häufig dass man nichts befürchten muss sofern man nichts zu verbergen hat.
Ich betreibe ein geschütztes, privates Forum um zusammen mit einem Bekannten ein spezifisches Thema zu diskutieren.
Das Thema an sich ist harmlos bringt aber leider mit sich dass es Schlagwörter erzeugt die man auf schwarzen Listen vermuten könnte. Abseits von Terror versteht sich aber dennoch Schlagwörter.
Die Verbindung zum Forum ist SSL verschlüsselt womit erwähnte Schlüsselwörter lediglich über die Telefonverbindung abgefangen werden können.
Der Server unterliegt einer täglichen Zwangstrennung und bekommt jeden Tag eine neue IP. Das ganze läuft über DynDNS. Außer dem Partner und mir kennt niemand die Adresse.
Vor ein paar Monaten gab es einen BruteForce Angriff auf den SSH Server. Der Angriff dauerte mehrere Tage und der Angreifer kannte offensichtlich alle in dem Zeitraum zugewiesenen IPs.
Zu dem Zeitpunkt scherzten wir noch darüber das es vll. von Seiten der Regierung kommt und sie die IP vom Provider bekommen. Die einzigen Alternativen wären der Partner selbst würde sich verantwortlich zeichnen oder die Leute von DynDNS.
Nach neuerlichen Leaks scheint uns der Gedanke an eine Regierungsaktion nicht mehr so abwegig was bedeuten würde man fällt recht schnell ins Blickfeld und wenn man das Interesse geweckt hat wird aktiv versucht Zugang zu beschaffen.
Ein paar Ausschnitte aus den Logs. Das ganze zieht sich über zwei Wochen und die IPs wurden recht lange genutzt. Das PW für den SSH Account ist natürlich nicht per BruteForce zu knacken. K.a. aber 30 Zeichen hats schon.
Was sagt die Fachwelt hierzu? Woher hat der Angreifer die IPs?
