The threat level is increasing! In 2014 alone, approximately 131,000 new types of malware were discovered daily – an increase of 250% when compared to the year before. This trend is continuing unabated: 9 million samples have already been discovered in the first quarter of 2015. It is not just the quantities that are rising at a staggering rate. The methods and types of malware are becoming increasingly sophisticated and harder to detect.
For example, the current trend is moving away from malware that is distributed in the form of email attachments (e.g. trojans) towards the distribution of links to websites that are infected with malware. This makes it more difficult to detect the source, since it is no longer directly connected to the user’s email. The malware is downloaded when a link is clicked. A hacker may infiltrate a trustworthy site with the goal of planting malware on it. To the user, it is difficult to recognize a link to a trusted site as a threat. Further, the developer of the malware can put another version online at any time as soon as the previous version is detected by antivirus software.
