in unseren Log-Protokollen habe ich heute ein neues Muster eines Angriffsversuches erkannt. Hierbei wird in diversen Wellen versucht, Informationen über eventuelle *.rar und *.zip Dateien zu erlangen. Details im nachfolgenden Quelltext:

Alles anzeigen
vorstehend ist nur ein Auszug des Gesamtprotokolls zu sehen. Die IP-Adresse ist einem chinesischen Provider zuzuordnen, die Sperrung erfolgt über folgenden Eintrag in der .htaccess:
# Beginn Aussperrung nach IP-4-Adressen
order allow,deny
allow from all
deny from 120.25.153.19
Da dieses Angriffsmuster erheblich von den üblichen /GET wp-*,php , /GET dump.sql oder /GET Administrator.. abweicht, haben wir diesen unauthorisierten Zugriff direkt an das BSI gemeldet. Falls Ihr in eurem Log ebenfalls Zugriffsversuche von der IP-Adresse 120.25.153.19 gehabt habt, die diesem Muster ähneln, zeigt dies bitte bei meldestelle@bsi.bund.de an.
Nachtrag: Da das Backup von Zeta-Projekten wahlweise auch im Root-Verzeichnis des Servers gespeichert wird in der Form ***.zip gespeichert wird, besteht hier zumindest theoretisch eine Schwachstelle. Ich suche mal nach einer entsprechenden Sperranweisung für die .htaccess. Falls spontan ein anderer User diese schon griffbereit hat, bitte posten.
