Among these channels could be spam email campaigns, social media networks, P2P networks, forum communities and platforms for free applications.
Once the payload file of .trosak ransomware virus is loaded on your system, it initiates a long sequence of malicious operations that disrupt system security and enable the threat to locate target files.

Distribution of .trosak Ransomware Virus
The so-called .trosak ransomware is a devastating cryptovirus that has been recently released in attack campaigns against computer users worldwide. Threat actors could be utilizing widely used tactics of distribution to infect computer systems.
One of the methods that may be used by the malicious actors behind .trosak ransomware includes the coordination of SPAM email messages — they are used to spread the threat by sending out messages that pose as legitimate notifications sent by popular Internet portals or services that you may be using. The virus files can be either directly attached or linked in the body. They can also be uploaded to fake download sites which are designed to appear like any of the popular Internet portals or vendor download sites. The malicious actors may use similar sounding domain names, certificates and hijacked design and contents to coerce the victims into thinking that they are accessing the legitimate address.
Another way that the threat may spread is through infected payloads — the use of various files that are infected with virus code. A popular example is the malicious document which can take any form: presentations, rich text files, spreadsheets and databases. Once they are on your PC a notification message will pop-up asking the target users to enable the built-in scripts. If this is done the virus infection will follow. The other popular technique is the inclusion of the code in application installers. They are malicious copies of legitimate setup files of popular end-user programs that have been modified with the .trosak ransomware code.
