According to a study from McAfee, cyber thieves are increasingly targeting intellectual property. Some attackers are specializing in stealing data from corporate computer systems. In particular, information thieves seem to be looking for trade secrets, research and development reports, marketing plans and source code. The report also noted that many companies are not taking adequate measures to protect information and are not going public with news of data security breaches. Of the companies that reported experiencing a data security breach, just half said they had taken steps to improve cyber security.
