Experiment reveals that dark web has become cheaper, busier and faster

Bitglass, a cloud security firm, has reported its findings on a study it performed in which researchers posed as a hacker on the dark web offering stolen credentials. The data offered, however, contained watermarks that allowed them to track the speed at which the information circulated. Data indicates that the information spread 11 times faster than a 2015 study revealed. The posts also received 13 times more views than those posted in the previous study. Collected data indicates that the dark web has become more heavily trafficked and much faster in recent years. Read more.

Researchers discover that hacking group is infiltrating mobile carriers

Cybersecurity researchers at Crowdstrike have been compiling data on a mysterious hacking group that has been quietly breaking into the systems of global telecommunications companies. Crowdstrike believes that these hackers, once embedded, can spy on anyone connected to the network with no need to break into anyone’s individual device. At this point in time, so little is known about those responsible for the hacking that, instead of attributing the activity to a specific group, the incidents are falling under “Light Basin,” an umbrella term used to describe the activity.
