GS1900-10HP hacked :\

GabrieleMax

When I try to connect to my GS1900-10HP it sends me a file named

Yq2b40+w, when I open it I have:

Index of /mnt/web/

modules.tar.lzma

pkg_clean.sh

unpkg.sh

The first file is a compressed file and inside of it I have a lot of files with *.ko extension something like codec.ko and decoder.ko, really strange

In the second file I have:

if [ -f /mnt/web/modules.tar.lzma ];then
    rm -rf /lib/modules/*
    umount /lib/modules/
fi

In the third file I have:

if [ -f /mnt/web/modules.tar.lzma ];then
    mount -t ramfs /dev/mem3 /lib/modules/
    cp /mnt/web/modules.tar.lzma /lib/modules/
    cd  /lib/modules/
    unlzma modules.tar.lzma
    tar -xvf modules.tar
    rm modules.tar
    cd -
fi

After a port scan I have:

[email protected]:/home/gabriele# nmap -sS -P0 -sV -O 192.168.1.230

Now how can I fix it?|

Hello @GabrieleMax

I'm curious how you found the problem.
Did you try to remove all other devices connected firstly and then connected PC with GS1900? 
I suspect if it is possible that the files were actually coming from other devices, for example, one of other servers, instead of GS1900. 
Could you have a try to remove all other devices connected with GS1900 and then connect PC again (only one PC) to see if there is still the same problem?
