Recently our website started to get a lot of requests for
/fqexpack url from devices with user agent, somehow connected to Android, like
Dalvik/1.6.0 (Linux; U; Android 4.0.4; GT-S5303 Build/IMM76D) Dalvik/1.6.0 (Linux; U; Android 4.0.3; M532 Build/IML74K) Dalvik/1.2.0 (Linux; U; Android 2.2; SAMSUNG-SGH-I897 Build/FROYO)
These requests has fairly uniform day time distribution.
Of course, our site doesn't have page with that address, and also we have not published any links with this substring.
Google knows nothing about it.
Our site is targeted to Russian audience, but these requests happens even when it is night in Russia.
Also we have IP-addresses of these users.
What do you think this link may mean?
Site is hosted at Amazon, it is a .NET IIS-hosted application.
