What, me worry?

Incidents of cybercrime via malware and exploits are on the rise, but if this recent poll is to be believed, people are still too blasé about their Internet security. The Unisys Security Index: Global Summary report 1 revealed the following:

More than 8,000 people were surveyed.”

How can we stop the botnets?

Botnets are a fascinating piece of software – yes, they really are!

Although they lie deep in the “dark” stack of widespread tools that are used to perpetrate cyber-crimes, they really shine as well-engineered structures. They are forced to constantly evolve because of the current and on-going “arms-race” between security experts and cyber-criminals.
