Internet insecurity

Once more unto the breach
Jun 3rd 2011, 11:02 by M.G. | SAN FRANCISCO

    DEFENCE companies have been left defenceless. The cyber attacks against Lockheed Martin and L-3 Communications, two American defence giants, as well as those against Google and America’s Public Broadcasting System (PBS) differ in their details. But they all highlight the fact that hackers are becoming ever more tenacious and creative in their attempts to get their hands on sensitive data.

    It’s not just American firms that are under attack. On June 2nd, a group of hackers calling itself “LulzSec” claimed that it had been able to get into the network of Sony Pictures. LulzSec (which also uses the moniker “The Lulz Boat”) claims it is behind the hacking of PBS’s website too.

    The rise of “hacktivism”, which involves groups of hackers not necessarily driven by financial gain (though this can be a handy by-product of their nefarious activities), poses a growing challenge to companies and governments. Often the motive is revenge. LulzSec claimed its attack on PBS was motivated by the media organisation’s decision to air an investigative report that included criticism of WikiLeaks, the organisation that has been publishing leaked diplomatic cables. Anonymous, a hacker collective that has gained global notoriety for penetrating the networks of credit-card companies and other organisations, has also justified some of its actions by saying they are protests at the way in which Julian Assange, the founder of WikiLeaks, has been persecuted by governments and courts.
