BAKU, Azerbaijan, Aug. 18
By Sadraddin Aghjayev - Trend:
DDoS attacks have become more intense since the beginning of 2021, Alexander Lyamin, Founder and CEO of the Russian Qrator Labs company, told Trend.
According to him, this year began in an explosive manner - with a DDoS attack with an intensity of 750 Gbps, consisting mainly of DNS-amplified traffic. This vector of attacks is one of the first and most studied, but nevertheless, it still remains popular among cybercriminals.
“In the first quarter of 2021, we saw a huge shift in the intensity of DDoS attacks: if in the fourth quarter of last year the average intensity was 4.47 Gbps, then in the first quarter of this year it was 9.15 Gbps,” Lyamin said.
“We have recorded such a leap for the first time. It is associated with the growing popularity of special services for organizing DDoS attacks - the so-called "booters". The owners of such services usually accept credit card payments and can launch an attack on any IP address set as the target. Now terabit speeds have become available through "booters", and therefore the dynamism of attacks has increased, and the time spent on it has decreased," Lyamin said.
He noted that earlier attacks of more than 1 Tbit/s intensity could last for several hours and were well prepared.
“Now you can order an attack at the same speed, but lasting for several minutes for only $100, and if it doesn't work, then you don't have to spend money on continuing the attack,” he added.
Lyamin emphasized that the bandwidth on the Internet is constantly growing, and the channels are expanding, so if earlier many attacks were less in bandwidth simply because they “hammered” the local last mile, now the last mile is fiber to each house, per gigabit to every apartment and even to every phone, as the rollout of 5G networks is taking place by leaps and bounds.
All this leads to the fact that even the most ordinary, not exceptional attacks begin to move imperceptibly from a segment with a bandwidth of 1-10 Gbps to a more serious segment - 10-100 Gbps. Today, it accounts for a third of all recorded attacks, ”Lyamin said.
