The guilty plea entered into federal court last week, by a contract IT worker, for disrupting a computer system used to monitor off-shore oil platforms shows that illegal hacking is likely to increasingly danger the physical world.In March of this year, the contractor was indicted for allegedly damaging computer systems, after Long Beach-based Pacific Energy Resources, Ltd. (PER) declined to offer the worker a full-time position.

According to a statement issued by the U.S. Department of Justice, the man consulted on the implementation of a system used by PER to electrically communicate and monitor for potential platform leaks.

Then, allegedly disgruntled, the consultant accessed the system without authorization and "caused damage by impairing the integrity and availability of data," according to the indictment. There is no indication of any environmental harm.

In a blog, last month, we covered the warning, from the research team SINTEF Group, an independent Norwegian think tank, to oil companies worldwide that offshore oil rigs are making themselves particularly vulnerable to hacking as they shift to unmanned robot platforms where vital operations are remotely managed. (Read: Hacking Oil Rigs).

And, earlier this year, a number of stories surfaced that highlighted the security dangers surrounding smart meters and the smart grid. As Thomas Claburn wrote in Black Hat: Smart Meter Worm Attack Planned -- smart meters being installed in consumers' homes are susceptible to the same types of attacks as PCs. So are, to some extent, medical devices. And The New York Times reported in March of 2008 in A Heart Device Is Found Vulnerable to Hacker Attacks:

The threat seems largely theoretical. But a team of computer security researchers plans to report Wednesday that it had been able to gain wireless access to a combination heart defibrillator and pacemaker.

They were able to reprogram it to shut down and to deliver jolts of electricity that would potentially be fatal - if the device had been in a person. In this case, the researcher were hacking into a device in a laboratory.

As I either worked in, or covered IT systems as a journalist, since the late 1980s -- one thing has been certain: security efforts lag system usage. It was true with the PC, which had viruses spread by diskettes. It was true with LANs, which saw its share of access control and system vulnerabilities. And those same types of vulnerabilities were only amplified with the advent of the Internet and Web-based applications. Unfortunately, I've little doubt we will see the same trend as "cyber" and physical systems converge.
