The group (individual?) that was behind the Nertra Ransomware which is now working as partner with Reveton has a TDS using almost all features :

If you land on it with Internet Explorer :
Angler EK --> Reveton.
Landing on Nertra Guys TDS redirecting to their Angler EK Thread dropping Reveton
Payload for instance :
d88c3f56565b18e95cf9bd0ebbd86d97

If you land on it with another Browser on Windows/Linux or Mac you get a Browlock :

Landing on Nertra Guys TDS redirecting to their Browlock  (By Reveton Team) Thread
Note that this one is going the awfull way in US (cf my last tweet) :


If you land on it with Android then you'll be redirected to a website that will push the download of the APK to the mobile without interaction. Note : no installation. User has to do an action. So it's Social Engineering.

Same TDS from Nertra actors pushing you on a Fake porn website (hosted on same IP as the TDS btw) which will drop an apk on the device.

The apk : fb14553de1f41e3fcdc8f68fd9eed831



Manually installing the dropped apk.
(Note the : prevent phone from sleeping :) )


Next step.
And here is what you'll get on reboot or if you manually launch this application from France :

Say Hello to Mr. Hollande and "Reveton" team on your mobile.
From United States :

Now Classic Ransomware Design in the US
(I checked to see if their was some CP for US there too. No)
Payment :
When you scroll down
(Note on Tablet this part will be on the Right as the page AutoScale)


Apktools on it.
./res/values/arrays.xml
Self-explanatory
http://pastebin.com/XTTH4P9q

Webview calling the Ransomware Design for NL.
It seems they are on that range :
94.228.208.227 --> 249
47869 | 94.228.208.0/20 | NETROUTING | NL | NETROUTING.EU | NETROUTING

I didn't try to dig and understand the data sent in the get call. (maybe IMEI, Mobile model etc..)
The locker is kind of effective. You can go on your homescreen but nothing else seems to work.
Launching Browser, callings Apps, or "list of active task" will bring the Locker back.

Recorded activity while trying to see how to get rid of it


I checked the design available are indeed those announced in the advert and are not worth being gathered as they are classic. (31 countries : AT - AU - BE - BO - CA- CH - CZ- DE - DK - EC - ES - FI - FR - GB - GR - HU - IE - IT - LV - MX - NL - NO - NZ - PL - PT - RO - SE - SI - SK - TR - US)
