When I checked the log I also saw an attack called "Cloaking" could you explain this to me.
Are you sure this is an attack? Because when I did a quick search on PC-cillin and "cloaking" I got this:

The Personal Firewall also offers a variety of functions that protects your system from hackers such as the cloaking option that prevents your computer from being found when connected to the internet. The Firewall also has three different levels of blocking from low to high because some programs require that certain ports on your computer are open.
What this leads me to believe is that you can turn off the ping feature (so your machine doesn't respond to ICMP requests and appears as "alive"). The only thing I can think of is that your machine is responding to the pings but getting no response back, which would mean either the attackers have ping turned off and/or are spoofing the source (hence, it's not in Amsterdam but perhaps really somewhere else).
