The relationship between TOR and ransomware

During your travels around the World Wide Web (or if you’re a House of Cards fan), you may have heard the TOR (The Onion Router) network of servers mentioned. This network was initially developed by the U.S. Navy as a way to anonymously browse the Internet. When used in that manner, the TOR network is a great concept and a lifeline for some users.

10 Questions Answered About Ransomware

In Q4 of 2015, Hewlett-Packard released research showing cybercrime costs U.S. firms an average of $15 million each year – double the global average. That figure is an increase of 19%, and digital criminal activity is only expected to grow. With the “Internet of Things” on the horizon, millions of new IP-enabled devices will soon be online, each one representing a potential target.

These powerful Trojans leave both consumers and businesses at their mercy, locking access to critical files and then extorting large cash payments to restore them.

How to configure Kaspersky's System watcher

In this post we would like to give you a good idea what the system watcher from Kaspersky can do for you and how you can configure it yourself.  Sometimes you don't find the time to do it due to other tasks and responsabilities, don't hesitate to call our help desk at that moment. 

The first question is of course, why would we use or configure the system watcher feature.

Kaspersky System Watcher scans the most relevant system event data. The monitor tracks information about the creation and modification of files, the work of system services, any changes made to the system registry, system calls and data transfers over the network. System Watcher also processes information about operations with symbolic links containing references to files or directories, modifications of the master boot record where the loader for the installed operating system is stored and interception of OS reboots. Moreover, it analyses the contents of the packets transmitted via TCP, the main Internet transport layer protocol, in search of any evidence of criminal activity. The data collection process is automated and does not require user interaction.
