cbrace said:I am pretty happy now with my VPS at tilaa.nl, but I ran into a really bizarre problem with the clock freezing, which I detailed here. Upgrading to two CPUs seem to have fixed it (as Tilaa support suggested), at the cost of a few more euri per month (No longer a Low End Box). Still wondering though whether anyone else has seen this problem with single-core FreeBSD VPSs.
At the end of last week, Hetzner technicians discovered a "backdoor" in one
of our internal monitoring systems (Nagios).
An investigation was launched immediately and showed that the administration
interface for dedicated root servers (Robot) had also been affected. Current
findings would suggest that fragments of our client database had been copied
As a result, we currently have to consider the client data stored in our Robot
To our knowledge, the malicious program that we have discovered is as yet
unknown and has never appeared before.
The malicious code used in the "backdoor" exclusively infects the RAM. First
analysis suggests that the malicious code directly infiltrates running Apache
and sshd processes. Here, the infection neither modifies the binaries of the
service which has been compromised, nor does it restart the service which has
The standard techniques used for analysis such as the examination of checksum
or tools such as "rkhunter" are therefore not able to track down the malicious
We have commissioned an external security company with a detailed analysis of
the incident to support our in-house administrators. At this stage, analysis
of the incident has not yet been completed.
The access passwords for your Robot client account are stored in our database
as Hash (SHA256) with salt. As a precaution, we recommend that you change your
client passwords in the Robot.
With credit cards, only the last three digits of the card number, the card type
and the expiry date are saved in our systems. All other card data is saved
solely by our payment service provider and referenced via a pseudo card number.
Therefore, as far as we are aware, credit card data has not been compromised.
Hetzner technicians are permanently working on localising and preventing possible
security vulnerabilities as well as ensuring that our systems and infrastructure
are kept as safe as possible. Data security is a very high priority for us. To
expedite clarification further, we have reported this incident to the data
security authority concerned.
Furthermore, we are in contact with the Federal Criminal Police Office (BKA) in
regard to this incident.
Naturally, we shall inform you of new developments immediately.
We very much regret this incident and thank you for your understanding and
trust in us.

Crest said:Sounds like a professional response to discovering compromised systems. They stored their password databases as salted hashs, didn't keep too much credit card data around and informed their customers by mail.
How about bank data (debit note)? Is this compromised?
Bank details are encrypted (two-way) in the database. However, it cannot be excluded that the attacker/s have also been able to obtain access to the key.
I can do better than that; I simply replaced the G with a T. This way hopefully no one will notice. Oh wait...OH said:You should add a threesome of zero's to that.
