New Quark Rules For GoldDream
New Quark rules (#00234 - #00237) are now available. These rules target GoldDream, a malware family that monitors SMS messages and phone calls and uploads them to remote servers. Check here for the rule details.
With these rules, Quark is now able to identify the GoldDream malware family as high-risk. In our experiment, Quark achieved 100% accuracy and 100% precision. Please check here for the APKs we tested.
Below is a summary report of a GoldDream sample (
ECA3A3666B0FD72028431431E7FAE6774A8CA692E35AE3CB44FD8F2AA418F746). The report shows that Quark identified the sample as high-risk, with a list of behaviors as evidence.Identified Well-Known Threats
With Quark’s rule classification feature, analysts can generate behavior maps and see how behaviors are related. This feature helps identify 2 well-known threats from GoldDream, as shown below.
1. Monitor SMS messages and phone calls
The behavior map shows that the
Lcom/sjhi/client/zjReceiver;onReceivefunction monitors SMS messages and phone call activity. It also calls theLcom/sjhi/client/zjReceiver;afunction to collect the data into files.Behaviors detected by Quark:
2. Upload SMS messages and phone calls to remote servers
The behavior map shows that the
Lcom/sjhi/client/e;afunction connects to a URL and writes a file to an output stream. If the output stream is from the URL, this indicates the function uploads a file to a remote server.Behaviors detected by Quark:
