At the same time several distribution techniques can be used, the most popular ones are the following:
- Phishing Strategies — The criminals will send out phishing email messages and create websites that impersonate well-known companies or services. The hackers will use stolen or fabricated content that appear to the victims as the real and authentic notifications and landing pages of these famous sites. They can directly cause the infection by presenting malware code or provide links from where the infection can be contacted.
- Malware Payload Carriers — There are certain files that are being used to lead to the infection. They can be documents across all popular formats: text documents, spreadsheets, presentations and databases. When they are opened by the victims a prompt will appear asking them to enable the built-in scripts (macros). If this is done the virus will be launched. The other popular method is to create malware application installers of popular programs which are often installed by en users: creativity suites, productivity and system utilities and even computer games.
