.encry Files Virus – Propagation

There is one main strategy which is used by the cyber-criminals to infect computers with Maktub Locker. This is to use an exploit kit which is often inserted as a result of a drive-by attack. These attacks can be spread when malicious objects, like URLs or files are introduced to victims. These may be spread in a couple of ways over the web, such as:

  • Spam e-mail messages that may pretend to be original ones. Those usually pose as e-mails from big companies and pretend to be invoices or receipts.
  • Posted URLs on social media chats or other e-mail spam messages that make them appear as if they were legitimate activation buttons that lead to the infection script.

The exploit kit is not only one object however. It is actually a set of obfuscated infection objects that check your system and antivirus before infection. Then, the kit runs the appropriate obfuscation in order to cause an unnoticed infection, leaving the victim no way of knowing that an infection is ongoing, until it’s too late and the files are already encrypted. One good method to stop such infection is to check your e-mails before opening them, using free services, such as ZipeZip (zipezip.com).

In addition to this, the malicious files, can also be spread in a more passive manner. You may encounter them to be uploaded online as game patches, software activators, cracks and other similar executables that pretend to be the ones you have downloaded online.
