  • Защита на WordPress от Bruteforce

    Много ботово се опитват да се логнат с brutforce и ето едно просто решение (не е 100% гаранция, но е втора бариера един вид…)
    # Protect wp-login
    <Files wp-login.php>
    AuthUserFile /www/.htpasswd
    AuthName „Private access“
    AuthType Basic
    require user amri
    </Files>

  • Voice recognition

    Разпознаване на глас, чрез гугъл: https://github.com/amsehili/gspeech-rec

  • Обратен ssh тунел (reverse ssh)

    Клиента се свързва с машината която има реално IP(DOMAIN.bg) и прави отворен порт 19999

    ssh -R 19999:127.0.0.1:22 [email protected] -oPort=33

    Когато на DOMAIN.bg се вържем през ssh на 19999 ще се свържем директно със ssh-а на машината с нереално IP

    Пример
    На машината с реално ИП (DOMAIN.bg):
    ssh [email protected] -p 19999

    Свързваме се директно към машината с нерелно IP

  • Подслушване на пароли, чрез tcpdump (ftp, http и т.н.)

    Проблема беше, че има фтп потребител на машината който влиза, но се знае паролата и за да не се променя затова се реши да се пусне tcpdump и така да се прослуша с каква парола влиза потребител в съответната машина:

    tcpdump -l -A src IP_CLIENT and port ftp

    tcpdump port http or port ftp or port smtp or port imap or port pop3 -l -A | egrep -i ‘pass=|pwd=|log=|login=|user=|username=|pw=|passw=|passwd=|password=|pass:|user:|username:|password:|login:|pass |user ‘ –color=auto –line-buffered -B20
