BlackMagic.A prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).

  • It modifies system permissions in order to hide itself.

 

BlackMagic.A uses the following propagation or distribution methods:

  • Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
  • Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
