Hetzner Robot был заражен, возможна утечка данных.

Пару минут назад получил письмо от Hetzner-а, с информацией, что они (инфраструктура) были заражены каким-то новым вирусом, который атакует данные в оперативной памяти. Были инфицированы их система мониторинга Nagios, а так же панель управления выделенными серверами Robot..

Все довольно серьезно, так как Hetzner-ы даже обратились к внешней конторе по it-безопасности для расследования этого инцидента. Пока говорят о том, что была утечка паролей. Пароли хранились с добавлением соли, и шифрованием посредством алгоритма SHA256. Однако они не исключают возможность расшифровки, поэтому просят пользователей сменить пароли от аккаунтов (например Robot-а).

Финансовые данные, такие как данные по кредитным картам, возможно так же были похищены, однако Hetzner-ы утверждают, что это не так. Они хранят только часть информации, а именно последние 3и цифры номера, тип карты и её дату истечения. По их информации, эти данные не были скомпрометированы.

Так же они обратились в Federal Criminal Police Office, для расследования инцидента.

Ну, что же: все массово идем менять пароль, а Hetzner-ам, желаю побыстрее справиться с этой ситуацией с наименьшими потерями.

Вот полный текст письма:

Dear Client

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
as compromised.

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
been affected.

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.

A special FAQs page has been set up at to assist you with further

Kind regards
