I am working on a project to identify the author of the malicious apk. To test my results I need dataset of malicious apks along with their authors. Currently I am working on a dataset which is very small. Could anyone please suggest some resources so that I can have a good amount of malicious apks along with their authors to evaluate my results ?
Another reasonably useful dataset that i've come across is:
The malware genome project manages a huge amount of malware samles that is also categorized. If combined with your data set, you might as well be able to identify authors.
You can request access here.
