being traced is not a big fear, it is unlikely you can actually trace back to the actual ip address for any but the most dumb.
and I believe that this opinion held by the hacker is our greatest advantage if used correctly.
As you know the web is a great place for storing data and great for long term storage of forensic data. Sure, today we may not be able to trace the activities but tomorrow we may be able to.
The hacker may get a surprise visit in 10- 20 years time from his hack or sooner and wonder how he was found...
Imagine: a central attack data registry that kept all relevant data indefinitely
and add to that a central "stollen data use" registry etc ....
who knows how IT forensics will develop in 5 years or so... it certainly is gaining momentum even now as the world gears up for the anticipated hacker onslaught against mobile phones and other portable devices. esp. regards online banking - ecommerce etc.
Possibly the weakest link [IP address allocation] could also be to our advantage.
An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there."
The designers of the Internet Protocol defined an IP address as a 32-bit number and this system, known as Internet Protocol Version 4 (IPv4), is still in use today. However, due to the enormous growth of the Internet and the predicted depletion of available addresses, a new version of IP (IPv6), using 128 bits for the address, was developed in 1995. IPv6 was standardized as RFC 2460 in 1998, and its deployment has been ongoing since the mid-2000s.
IP addresses are binary numbers, but they are usually stored in text files and displayed in human-readable notations, such as 172.16.254.1 (for IPv4), and 2001:db8:0:1234:0:567:8:1 (for IPv6).
The Internet Assigned Numbers Authority (IANA) manages the IP address space allocations globally and delegates five regional Internet registries (RIRs) to allocate IP address blocks to local Internet registries (Internet service providers) and other entities.
so the world wide web regulates IP address allocation better...registry of machines and owners of some sort... hmmmmm...would be so easy when you think about it
