A Trojan for Android included in SDK 呀呀云 (Ya Ya Yun). It is used in software development. This SDK provides users with an opportunity to exchange text, voice and video messages. The main purpose of Android.RemoteCode.127.origin is a covert download and launch of additional malicious modules.
Launch of Android.RemoteCode.127.origin depends on the method used by a developer to initialize SDK in their application. Usually it happens when the program is launched either in the Application class, or in any of its Activities. Once launched, the Trojan sends a request to the C&C server https://hs.***bao.com/get (in some modifications it is http://hs.***vv.info:9800/get) which looks the following way:
{
"operatorType":"",
"model":"Philips_S307",
"osVersion":"4.4.2",
"appId":"1001305",
"vendor":"Philips",
"imei":"********0006551",
"androidId":"********743b4627",
"connectionType":"WIFI",
"mac":"**:**:**:81:77:dc",
"requestType":"jar",
"osType":1,
"ip":"***.***.137.136",
"sdkVersion":"1.0.3",
"appVersion":"1.8",
"longitude":"",
"latitude":"",
"imsi":"",
"uuid":"************4807a86dac9556ff07de",
"idfa":""
}
In addition, if an application with the Trojan SDK has privileges to determine coordinates, the request gets an indication of the last known location of the infected device.
In return, the server can send to the malicious program a task which looks the following way:
{
"result":0,
"msg":null,
"tasks":[
"tasks":[
{
"id":356,
"scriptType":null,
"type":0,
"binUrl":" " https://v.***aya.cn/core_xd_356 ,
"md5":"92801af38f6dfe38fbb8b63748006deb",
"className":"com.x.d.core.service",
"function":"main",
"functionParam":null,
"shell":"",
"pkage":"",
"exeDelay":0,
"scheduleTime":null,
"cancel":null,
"partnerId":null,
"countLimitType":2,
"binNumber":"leyou",
"taskType":1,
"activity":null,
"taskFlag":0,
"msgId":"********f6a7f20cbe2499cf"
}
]
}
It has a link to download one of the malicious modules, for example Android.RemoteCode.126.origin. After the download, the module is launched using the DexClassLoader class.
