Large scale UDP attacks: How to combat the new cyber attack trend

ENISA has today issued an information Flash Note, ‘Large scale UDP attacks: the 2014 trend and how to face it’ that analyses and tracks recent UDP attacks and provides recommendations on how to face them.

Published on February 26, 2014

The Agency has followed the latest news that show an increase of large scale attacks exploiting specific vulnerabilities of the Internet core protocols. In the latest cases, the Network Time Protocol (NTP), which allows synchronizing devices to the coordinated universal time (UTC), has been misused.

More specifically, in December 2013, a vulnerability in this UDP protocol became mainstream and started to be exploited for large scale reflection attacks leading to a dramatic increase of the size of denial of services.

ENISA looks into the new trend and  issues a series of recommendations to network providers, which they can already put in place to mitigate these threats.
