Malicious content delivered over SSL/TLS has more than doubled in six months

Threats using SSL encryption are on the rise. An average of 60 percent of the transactions in the Zscaler cloud have been delivered over SSL/TLS.

An internet-connected fish tank let hackers into a casino’s network

A high-tech, internet-connected fish tank in a North American casino has been used to exfiltrate data from the company’s network.

In addition, almost three quarters (71%) of the attacks mitigated by Corero lasted 10 minutes or less. Due to their small … More ?
