BotNet on the Rise
IUT-CERT has received some reports on suspicious link request on HTTP 404 web
server log file. All get parameters values were requested with the value of
http://babyc***b.fortunecity.co.uk/index.htm. Visiting the suspicious site, we
found a PHP malcode that was encrypted by the malicious attacker. After
decrypting the code, we found that the attacker is trying to exploit remote
file inclusion vulnerability that is why she is trying to inject the code in
web site variables. Successful exploitation of this vulnerability leads to
execution of the malcode on the vulnerable server.
After execution of the malcode, the code is trying to initialize a connection
to one of the following sockets:
homelessman.weedns.com:8080
burningman.weedns.com:8080
ballslessman.weedns.com:8080
mcar.dd.blueline.be:8080
mcarlos.opendns.be:8080
ns10.suroot.com:8080
mcarlos.dnip.net:8080
1.ns03.americanunfinished.com:8080
After the successful connection, the Bot sends a random number, password and
the nickname to bot handler and waits for commands. These Bot nets are also
used for further organized attack such as Distributed Denial of Service. It?s
recommended to all Network administrators to filter the above connections.
