Once more unto the breach

DEFENCE companies have been left defenceless. A prominent internet giant has found itself the target of an online plot that allowed outsiders to read some of its users’ emails. And a media organization has hit the headlines after its own website was vandalized by digital intruders. 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. In a statement, the group said it had accessed details of a million customer accounts, including email addresses and dates of birth. Sony’s executives are investigating the group’s claim. If it turns out to be true, it will be a huge embarrassment for the company, which is only just recovering from another recent attack that forced it to shutter its high-profile PlayStation network for several weeks, costing it millions of dollars.

LulzSec claims it is behind the hacking of PBS’s website too. Here the hackers stole passwords and other sensitive data, as well as posting a false story claiming that Tupac Shakur, a rapper who died in 1996, was in fact alive and kicking in New Zealand.” LulzSec also separately posted a message justifying its attack on Sony, saying the company’s approach to handling sensitive data was “disgraceful and insecure”.

The rise of “hacktivism”, which involves groups of hackers not necessarily driven by financial gain, poses a growing challenge to companies and governments. Often the motive is revenge. LulzSec claimed its attack on PBS was motivated by the media organization’s decision to air an investigative report that included criticism of WikiLeaks, the organization 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 organizations, 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.

Other hackers are launching what many reckon are government-backed intrusions over the internet. This week it was revealed that a cyber attack originating from China had used a technique known as “spear phishing” to extract Gmail passwords from unwary users. This was used to read the emails of senior American officials, journalists, Chinese political activists and government officials in several Asian countries, most notably South Korea. The Chinese government denied it had anything to do with the attacks, but some experts note that Chinese hackers often operate independently, but with the silent approval of the state.
