It is well known that Internet pornography is somehow prohibited but it is extremely dangerous when it's accessed by unauthorized people. Take the example of kids that must be protected against all kinds of pornography, several security companies trying to develop powerful solutions to defend users' computers.

In the past, authorities from the every corner of the world started an impressive offensive against hack attacks, spam and other illegal activity, trying to improve the online security of every user.

Some time ago, a former teacher was arrested because his computer contained spyware infected applications that displayed pornographic content to some students. This time, a new case was reported in California where 66-year-old Ronald C Kline, a former senior judge was sentenced to 27 months in jail for owning child pornography. The case is at least interesting because it was reported that Kline's computer was hacked by Canadian hacker Brad Willman who installed a Trojan file containing images of child abuse sent to many computers. After the installation, the hacker connected to the suspected computer and started to search for potential child pornography. Ronald C Kline was one of the affected users to attract the attention of the authorities that were closely monitoring the case.

"Ronald Kline's conviction has brought to the end six years of legal arguments about whether evidence gathered by the Trojan horse was admissible," said Graham Cluley, senior technology consultant for Sophos. "Few will shed tears over Kline going to prison, but the case does raise interesting questions over whether illegal hacking and the distribution of malware can ever be justified. Some may worry that this case will be viewed as a green light for other hackers to infect computers with their malicious code," security company Sophos reported.
