Small, Bit-and-Piece Cyber Attacks increase 233% in 2021, According to Nexusguard
Attackers rely on small-sized patterns to avoid detection, as predicted by Nexusguard researchers
SINGAPORE - Media OutReach - 19 October 2021 - Small bit-and-piece DDoS attacks (distributed denial of service) boomed by 233% in the first half of 2021, revealed Nexusguard researchers in the
Attackers are continuing to diversify their approaches with bit-and-piece attacks to bring down target networks and infrastructures. More than 95% of attacks were smaller than 1Gbps each, of which Nexusguard analysts believe a majority were launched using readily available and inexpensive DDoS-for-hire services. Rather than launching large bandwidth attacks against their targets, researchers noted that perpetrators chose to employ attacks using high packet-rate loads of small-sized traffic from DDoS-for-hire services, with the aim of evading DDoS mitigation detection systems.
"The high level of intricacies behind communications service provider networks causes them to generally allow all types of traffic to pass through, which leads to smaller or spoofed types of attacks to strike undetected," said Juniman Kasman, chief technology officer of Nexusguard. "Behavioral detection and mitigation approaches are strongly recommended for targeted networks since they can compare peacetime with battles and take a wider range of factors into consideration than anomalous thresholds or attack signatures."
Traffic spoofing and UDP-style attacks were popular in the first half of the year, with an 84% increase in UDP attacks compared to the previous six months. Nexusguard observed several types of UDP attacks in use, one of which can cause "Black Storm" attacks theorized in recent research. Nexusguard researchers witnessed several service providers bear the brunt of DDoS attacks, including
Nexusguard's TAP100 Program helps CSPs quickly launch anti-DDoS capabilities to protect customers. The TAP100 Program removes the hardware barriers associated with typical anti-DDoS service ramp-up, allowing CSP product teams and C-suites to capture new revenue opportunities and ensure superior customer service.
