\section{Sharktech}
|
||
|
|
Sharktech is a provider that focuses on DDoS prevention, such
|
||
|
|
as for gaming servers. Has a data center in Denver.
|
||
|
|
Looks good. Manually provisions servers over a few days.
|
||
|
|
Good local speed and latency.

First login, kernel is:
|
||
|
|
\texttt{Linux debian 3.16.0-4-amd64 \#1 SMP Debian 3.16.36-1+deb8u1 (2016-09-03) x86\_64 GNU/Linux}
|
||
|
|
It isn't up-to-date. Running Debian 8.6. The \texttt{dmesg} showed the kernel had already
|
||
|
|
barfed a couple times (USB time outs and more).
|
||
|
|
|
||
|
|
IPMI http connection is in cleartext!!! Doesn't redirect to https. https has failed SSL
|
||
|
|
certificate (like every other Supermicro on the planet). IPMI requires Java junk.
|
||
|
|
Server was running for a few days before I could update it.

\begin{itemize}
|
||
|
|
\item Default IPMI connection is in cleartext http.
|
||
|
|
\item SSL certificate for Supermicro IPMI is bad (like all of them).

||
|

||
|
|
\item Root password for server and IPMI is sent via email.
|
||
|
|
\item There is an attack window between their machine imaging and first login.
|
||
|
|
\item Customer should control timing of first power on.
|
||
|
|
\item System is also possibly vuln during the ISP's initial power up and commissioning period.
|
||
|
|
\item First reboot, the system hung (.png XXX).
|
||
|
|
\item Hard reset, lots of DHCP queries at boot.
|
||
|
|
\item A \texttt{debian} user was on the system, password unknown. Check \texttt{/home}!
|
||
|
|
\item They block NTP to prevent DDoS, so you have to use their time server

|
|
\texttt{time.sharktech.net}
