The law and law enforcement agencies are geographically organized but the use of Internet by cyber criminal knows no boundaries, a security analyst said.

Mike Small, a senior security analyst at Kuppinger Cole, said that Cloud services are attractive to hackers as they are not only cheap to set up and easy to use but also because they usually need only a credit card to get access.

Referring to misuse of LinkedIn by hackers, Mike said, "This incident illustrates the difficulties faced in a world where the law and law enforcement is geographically organized but criminal activities using the internet cut across these boundaries."

Social network LinkedIn earlier this week filed a suit against unknown scammers who illegitimately created thousands of bogus profiles and used them to gather data about real people on the site.

The hackers allegedly used Amazon's Elastic Compute Cloud service to perform the illegitimate act, known as data scraping.

The identity of the scammer/hackers is still unknown, but the social network expects to be able to spot the hackers by serving third-party discovery on AWS as the hackers had used Amazon's Cloud service.

LinkedIn, which hosts the CVs of 259 million people, said in the complaint that the hackers had caused "ongoing and irreparable harm" to it.
