I observed requests to my webserver to retrieve Bitcoin wallet files:

The files they are looking for are:

wallet - Copy.dat
wallet.dat
wallet.dat.1
wallet.dat.zip
wallet.tar
wallet.tar.gz
wallet.zip
wallet_backup.dat
wallet_backup.dat.1
wallet_backup.dat.zip
wallet_backup.zip

I've seen a couple of such request a couple of years ago, but it's the first time I see that many. The first time I observed this was late 2013, in the middle of the first big BTC price rally.

Please post a comment if you observed similar requests.
