Description[]

A hijacked host works for somebody else, without the owner knowing it. The diagrams show examples of a hijacked machine being used as a proxy name server and proxy web server.

This occurs when a trojan has invaded the computer as a result of a security exposure. For example, the machine may have been connected to the Internet while it had a trivial password. A hijacker has broken into the system by applying the hundred most frequently used passwords to the "root" administrator ID, and one of them matched. He has installed the trojan, and it will abuse the host by using its computing resources and its bandwidth. Hijacking is an illegal, criminal act in any country.

Operating Systems - October 2010[]

In October 2010, the same hijacking process was still in use. Sample operating systems detected were

  • Apache/2.2.4 (Unix) PHP/5.2.1
  • thttpd/2.25b 29dec2003
  • Microsoft-IIS/6.0
  • WebNet Modulex Web Server (c) 1998-2004 IO Technologies A/S
  • Apache/2.2.3 (CentOS)
  • Apache/2.2.9 (Debian) PHP/5.2.6-1+lenny8 with Suhosin-Patch mod_python/3.3.1 Python/2.5.2 mod_perl/2.0.4 Perl/v5.10.0
  • Apache/2.2.9 (Ubuntu) PHP/5.2.6-2ubuntu4.1 with Suhosin-Patch

Notifying somebody about the intrusion[]

A typical example: vegasinternationalcasino.com. This is a scam that is redirected from a disposable domain.

xasisar.com 210.172.161.135 
name servers: 
NS1.NERIEMLARIS.COM 202.82.63.68 
NS2.HARTONGSHE.COM 210.115.61.211 

(if you don't know how to get these IP addresses, one way is shown in the chapter Hijacked_host#Sending)

Do a whois look-up of the IP addresses[]

You can try with dnsstuff.com, but it might not give the addresses. In most cases it is useful: put the IP address in the "IPWHOIS Lookup" field, and when you get the results, click the link to show the email addresses.

The following example uses the Unix commands.

whois 210.172.161.135

gives no email address but a code TW184JP for [Technical Contact] - so use command:

whois -h whois.nic.ad.jp TW184JP 

Let's go to 202.82.63.68 - relevant details from the whois output:

% [whois.apnic.net node-2] 
tech-c: TA114-AP 

There are also other tech-c lines later but we'll see this is enough. Use command:

whois -h whois.apnic.net TA114-AP 

And you'll get

tech-c: NOC18-AP 
tech-c: JL1059-AP 
tech-c: DL430-AP 
(and their addresses) 

Actually in this case the NOC address was already in the first reply, but that isn't always enough. Also, usually you don't have to use a specific WHOIS server - for example:

whois TA114-AP

but I used it here as a "worst case" example. In the case of TW184JP the server was absolutely necessary.

Sending[]

Send these people friendly messages that their customers should clean up the computer at that IP address immediately and make it more secure in the future, by changing administrator passwords. Sample messages follow for each type of hijack operation.

If you like, you can give them extra info:

  • In the case of WWW, give them the domain address, because most spamversites don't work with raw IP. In many cases the spammers cycle "their" servers so fast that this info will be obsolete by the time your message is read, but it gives credibility anyway. For example:
    • dig +trace kidbopcd.com
kidbopcd.com.           600     IN      A       200.170.112.252
  • in the case of name servers, add the DNS lookup that lead you to the IP, for example:
    • dig +trace kidbopcd.com
kidbopcd.com.           172800  IN      NS      ns1.obtundert.com.
kidbopcd.com.           172800  IN      NS      ns1.suffoccateter.com.
kidbopcd.com.           172800  IN      NS      ns2.excentriccod.com.
kidbopcd.com.           172800  IN      NS      ns2.terkclass.com.
    • dig ns1.obtundert.com
ns1.obtundert.com.      172422  IN      A       203.129.232.82

In October/November 2007, the image server strategy changed. Instead of being spread over up to 5 image server IPs at a time, rotating 3 or 4 times a day, there was just one fixed address for all image serving:

Sample Hijacked Name Server alert message[]


Please read this information carefully. It concerns a security breach 
on your computer

On your IP address at xxx.xxx.xxx.xxx there is a trojan proxy name server installed,
 that is being used by a pharmacy spamming gang to provide access to illegal web sites.

You can prove it with this link

https://dnsquery.org/dnstraversal/fraudsitename/A
>> ns1.dnsserver1.com [xxx.xxx.xxx.xxx] << your address
>> ns2.serverdsn2.com [xxx.xxx.xxx.xxx] << your address


DISCOVERY AND REMOVAL
To discover the name of the trojan, you need to find the user process
attached on udp port 53 (DNS)

  fuser -n udp 53

The response will contain the pid of the process, for example 1234
Use that process ID to find the name, for example using the Linux command

ps wax | grep 1234

You will find it there. You can issue the "kill" command to terminate it.

One possible name that is use by the hackers for the trojan is uirqd but it may vary.

For a trojan to be installed, there is usually a trivial password used on the root or
administrator account. 
It should be changed to a non-trivial password to avoid further break-ins,
before deleting the trojan process.

If you are not the administrator for this machine, please forward on these instructions.

Thank you from
The Pharmacy Alert Security Team

Relentless pursuit[]

You can even follow up later: if those people are alert, or if the spammers change the IP for another reason, you can repeat this with the new IP.
