How to trace a drive-by download? I was using the default Android browser and I noticed a drive-by download.

The file is sexplay-r8.apk MD5 (sexplay-r8.apk) = 61ec2c6dab14c53ca323ee0dbcad112e 

It looks very much like a malware to me:



What should I do now ? How can I find what triggered the download of this file ?

I'm interested in triggering the download again, but I can't find a way to consult the history of the browser. Android isn't very forensics friendly.
To access the browser history, tap the "tabs" menu. (Looks like the tabs of a file folder and is next to the overflow menu, which itself looks like three vertical dots.)

Once you can see your open tabs plus the blank one to add a new one, tap the overflow menu.

You should see four options


New incognito tab
History
Saved pages
Settings


(I think you know what to do.)

This is on a Galaxy Nexus with Android 4.1.1.
