111 0 Kommentare Adversaries Continue Cyberattack Onslaught with Greater Precision and Innovative Attack Methods according to 1H2022 NETSCOUT DDoS Threat Intelligence Report

NETSCOUT SYSTEMS, INC. (NASDAQ: NTCT) today announced findings from its 1H2022 DDoS Threat Intelligence Report. The findings demonstrate how sophisticated cybercriminals have become at bypassing defenses with new DDoS attack vectors and successful methodologies.

"By constantly innovating and adapting, attackers are designing new, more effective DDoS attack vectors or doubling down on existing effective methodologies," said Richard Hummel, threat intelligence lead, NETSCOUT. "In the first half of 2022, attackers conducted more pre-attack reconnaissance, exercised a new attack vector called TP240 PhoneHome, created a tsunami of TCP flooding attacks, and rapidly expanded high-powered botnets to plague network-connected resources. In addition, bad actors have openly embraced online aggression with high-profile DDoS attack campaigns related to geopolitical unrest, which have had global implications."

Deployed in most of the world's ISPs, large data centers, and government and enterprise networks, NETSCOUT Arbor DDoS attack protection solutions send anonymized DDoS attack statistics to NETSCOUT's Active Level Threat Analysis System (ATLAS). This data, which includes visibility into more than 190 countries, 550 industries, and 50,000 autonomous system numbers (ASNs), is then analyzed and curated by NETSCOUT's ATLAS Security Engineering and Response Team (ASERT) to provide unique insights in the report. No other vendor sees and knows more about DDoS attack activity and best practices in protection than NETSCOUT.

Key findings from the 1H2022 NETSCOUT DDoS Threat Intelligence Report include:

There were 6,019,888 global DDoS attacks in 1^st half of 2022.
TCP-based flood attacks (SYN, ACK, RST) remain the most used attack vector, with approximately 46% of all attacks continuing a trend that started in early 2021.
DNS water-torture attacks accelerated into 2022 with a 46% increase primarily using UDP query floods, while carpet-bombing attacks experienced a big comeback toward the end of the second quarter; overall, DNS amplification attacks decreased by 31% from 2H2021 to 1H2022.
The new TP240 PhoneHome reflection/amplifications DDoS vector was discovered in early 2022 with a record-breaking amplification ratio of 4,293,967,296:1; swift actions eradicated the abusable nature of this service.
Malware botnet proliferation grew at an alarming rate, with 21,226 nodes tracked in the first quarter to 488,381 nodes in the second, resulting in more direct-path, application-layer attacks.
