The biggest ISP globally, AT&T said its network was persistently being attacked, with 30bn-and-more malicious scans occurring daily. According to Vice-President for Security Solutions Jason Porter at AT&T, the majority of these scans are investigative campaigns where miscreants hunt to find feeble entry points. AT&T was able to stop just 5bn of the scans during 2015, says the organization.
The attacks happen in an astounding number; however, the majority is connected to scripts, implying that rather than human error, the attacks show an immense scale of automation.
