DDoS Attack Frequency Grows 40%, Low Volume Attacks Dominate
The frequency of DDoS attacks have once again risen, this time by 40% year on year, according to Corero Network Security.
While frequency has increased, the duration of attacks decreased with 77% lasting ten minutes or less, of which 63% last five minutes or less. Perhaps more concerning is that, having faced one attack, one in five organisations will be targeted again within 24 hours.
“With Internet resilience coming down to a fraction of a second, it’s easy to see why DDoS attacks are considered one of the most serious threats to Internet availability today resulting in damage to a brand’s reputation, customer trust and revenue. As short duration attacks are much quicker – with 63% lasting under five minutes, many organisations are failing to identify that they’ve been hit by a DDoS attack. This lack of correlation with service lagging, or even failure, leaves organisations vulnerable as they’re neither successfully mitigating the attack nor the damage that is inflicted to the customer experience, affecting loyalty and ultimately causing revenue erosion.”

Other key highlights in the report are:
- Low volume, sub-saturating attacks continue to dominate (94% less than 5Gbps)
- Whilst still infrequent, attacks over 10Gbps have doubled
- Organisations faced an average of 8 attacks per day in Q2 2018, an increase of 40% compared to the same quarter in 2017.
