An integral part of the Sucuri project is to research and monitor current attacks as a way to improve our defense techniques. To achieve that, we have been running a few Honeypots for almost a year and collecting data from the attacks used and learning from them.
After a year, I think we are ready to start sharing the information we have learned…
The first step was to create a page with information about the systems involved on web attacks. We also have two blacklists updated daily, the first one is composed of the domains that are hosting the malware/php/perl scripts, while the second blacklist is composed of the IP addresses that are actively scanning our honeypots. You can check them out, plus the tools used at Blacklist and Research based on web attacks.
Now, the second step is to write about the attacks we are seeing to help educate others…
Looking at SSH scans
All our honeypots have a modified SSH server running where we collect every connection attempt, user name and password used and everything typed if the attacker gets access via SSH. During the course of 1 year, we recorded more than 1,600 different SSH scans to our systems. The data bellow is only for the last few months and the first number you see is in how many different scans it was logged.

It is interesting to note that in the first column, we have the user name and we see many entries for 123456 with the password of testuser or bill. My guess? Someone messed up the password lists and inverted the order… Anyone have ideas?

Complex password logged
Most of the scan attempts were using very common passwords, but some of them had really complex passwords that I can only imagine that are used as backdoors or as default passwords for some common systems. Anyone have clues? I “googled” and didn’t find anything..

Interesting breakdown, reminded me how twitter detects weak password by loading a dictionary of weak password with assigned strength.
Can you also be detail about what "malware/php/perl scripts" you run and the platform environment? This will be helpful to sort out some demographic info regarding the attackers.
Ha! I especially love this complex password: teiubescdartunumaiubestiasacahaidesaterminam
Romanian for: "I love you but you do not love me So let's end it"
Some of the complex ones definitely don't appear to have a pattern, but others do:
!@#$%^&*() is 1 through 0 on the keyboard while holding the shift key.
)(*&^%$#@! is the reverse of that above.
1q2w3e4r5t6y is simply a number and the key below it.
And so on..
A permanent stats overview would be nice I think. Seems like the most complex ones have been harvested by just spidering public information. For example googling one of the passwords you listed, the following website is encountered:
http://antispam.andreotti.nl/spamlog200910.txt
which also contains difficult(long) passwords like this one for example:
#mafiavafute197532@%!?*
Jay: Most of the attacks I am seeing are against Linux boxes, but we have some windows-based too. Look at the blacklist link to see all the tools.
NTulip: lol, thats very funny…

I would say that a lot of those passwords are l33t'ish and are probably passwords in other malware. Some have obvious patterns.
