Corporate Monday blues as malware strikes perimeters

Corporate networks report massive increase in malware detections on Monday mornings.

By CBR Staff Writer

Corporate networks are most vulnerable to malware attacks on Monday mornings when users reconnect their devices to the corporate network.

The pattern hints that the security perimeter within organisations are dissolving with the increasing use of devices both inside and outside the corporate security perimeter.

The revelation was made in the annual NTT 2015 Global Threat Intelligence Report, which said that Finance is the most targeted sector, representing 18% of all detected attacks.

It also highlighted that 56% of the attacks targeted towards NTT’s clients came from US based IP addresses.

The report added that the vulnerabilities are not new, as 76% of all identified issues throughout the systems were more than two years old, and 7-10% of exposed vulnerabilities were discovered with user systems.

Dimension Data group executive Matthew Gyde said getting access to malware is becoming easier through the dark net which reaps huge returns on investment for cybercriminals.

Gyde added: "It appears that ssuccessful exploits occurs over the weekend when end users – and their devices – are outside the security controls of the corporate network.

"Controls that address this trend must focus on the user and their devices, regardless of location, and points out that seven of the top 10 vulnerabilities identified were on end-user systems.

"End-users become a liability and that’s because their devices often have many unpatched vulnerabilities."
