Technology from FireEye was used to perform the analysis of both outbound and inbound network communications of 14 organisations, both public and listed, with an average size of 5000 employees.
Out of 15 586 security incidents recorded during the period of the analysis, 49% were related to unknown threats.
For 11 of these organisations, callbacks were initiated by the same hosts that were previously identified as infected by a malware object or browser exploit, within an interval of a few minutes after the infection.
It was found that each organisation was in average subject to 43 security incidents per day. It was also discovered that organisations were averaging two new infected devices each day and 30 exfiltrations of data per day.
The ability to reduce the time spent to discover and respond to an ongoing attack is primordial for organisations to scale down the window of exposure to unknown threats.
