Threat Intelligence Report Shows Massive Uptick in DDoS Attacks
Threat Intelligence Report Shows Massive Uptick in DDoS Attacks
NETSCOUT recently released its semi-annual Threat Intelligence Report with deep insights into the notably distributed denial-of-service (DDoS) and cyber activity during the second half of 2021. The report contains troves of valuable information about the ongoing threat posed to organizations across the public and private sectors, including government agencies and other public sector organizations.
As always, this latest edition of the report is chock-full of DDoS attack statistics, trends, and insights from the elite NETSCOUT ATLAS Security Engineering and Research Team (ASERT). And the data from this most recent report tells a simple and somewhat frightening story; DDoS attacks continue to be a major threat and are becoming more sophisticated.
While there are numerous, useful findings and insights into the current threat landscape included in the report, there are seven findings that truly stand out and that every cybersecurity professional should be aware of. Each raises a significant concern and should be part of any discussion around how to bolster the cybersecurity posture of organizations across the public sector.
Here are what we consider the seven most imperative findings from the latest Threat Intelligence Report.
- DDoS attacks continued to exceed pre-pandemic levels. During the second half of 2021, cybercriminals launched approximately 4.4 million DDoS attacks, bringing the total number of DDoS attacks in 2021 to 9.75 million. These attacks represent a 3 percent decrease from the record number set during the height of the pandemic but continue at a pace that’s 14 percent above pre-pandemic levels.
- DDoS extortion and ransomware operations increased. Three high-profile DDoS extortion campaigns simultaneously operating worldwide is a new high. Ransomware gangs including Avaddon, REvil, BlackCat, AvosLocker, and Suncrypt were observed using DDoS to extort victims. The number of triple extortion attacks consisting of DDoS, data theft, and ransomware also increased in 2021.
- VoIP services were targets of DDoS extortion. Worldwide DDoS extortion attack campaigns from the REvil copycat were waged against several Voice over Internet Protocol (VoIP) services providers, costing millions of dollars of damage.
- DDoS-for-hire services made attacks easy to launch. NETSCOUT ASERT examined 19 DDoS-for-hire services and their capabilities that eliminate the technical requirements and cost (e.g., some are free) of launching massive DDoS attacks.
- Server-class botnet armies arrived. Cybercriminals have not only increased the number of Internet of Things (IoT) botnets but also have conscripted high-powered servers and high-capacity network devices, as seen with the GitMirai, Meris, and Dvinis botnets.
- Direct-path attacks are gaining in popularity. Adversaries inundated organizations with TCP- and UDP-based floods, otherwise known as direct-path or non-spoofed attacks.
- Attackers targeted select industries. Those hardest hit include software publishers (606% increase); insurance agencies and brokers (257% increase); computer manufacturers (162% increase); and colleges, universities, and professional schools (102% increase).
With DDoS activity increasing, government cybersecurity professionals and cyber warriors need to have an understanding of DDoS attack trends and bad-actor tactics, techniques, and procedures. This level of understanding and knowledge is essential for preparing an adequate cyber defense. This knowledge is particularly important now amid the Russian-Ukrainian conflict when DDoS attacks are being leveraged as a form of geopolitical protest and cyberwarfare.

Every year, there are more and more security breaches, and it gets harder and harder to spot them. According to a leading cybersecurity vendor1, it takes almost seven months for organizations to find breaches, which gives malicious attackers plenty of time to get what they want.
Most often, system misconfigurations like default settings or credentials leave the door wide open for exploitation, resulting in these breaches. As organizations grow, this problem only gets worse because quick changes frequently result in skipped steps.

The Ukraine-Russia conflict began when the Russian military invaded Ukraine on February 24.
Yet the cybersecurity and cyber warfare elements of this conflict began before initial combat action. Ukraine was hit with numerous cyberattacks against its government and banking systems in the lead-up to the conflict, with experts blaming Russia for the cyberattacks. And within the first 48 hours, multiple U.S. agencies noted that cyberattacks from suspected hackers in Russia increased by over 800%.

There has been an increased focus among U.S. government agencies on adapting to modern IT environments and enhancing cybersecurity solutions. This increased focus on security government networks, data, and critical infrastructure is a result of ongoing digital transformation initiatives that are resulting in more mission-critical connected systems and more data for agencies to secure. It’s also a result of the increased number of cyberattacks and more sophisticated cyber-criminals that are targeting our nation’s networks.

With another busy year behind us, it’s time to look ahead to fiscal year (FY) 2022. The official information technology (IT) budget request is $97B, a 4% increase over FY21, which would be a new record. Of course, those numbers undercount all the IT spending that goes unreported. Furthermore, remaining provisions in the American Rescue Plan, the Technology Modernization Fund and IT provisions in the Infrastructure Bill will represent additional pockets of opportunity worth billions for channel partners and technology vendors.

Zero Trust is an approach to network security which assumes that just because something is on your network, doesn’t necessarily mean it is trustworthy. Zero Trust allows organizations to apply security controls to network traffic within the perimeter, not just at the edge.

Current IT modernization initiatives are challenging federal agencies to implement significant changes to their infrastructure at a breakneck pace. As they look to keep pace with an increasingly sophisticated cyber threat environment and accommodate workflows shifting to the cloud, the federal government is looking to zero trust as a solution. Zero trust is a security model that maintains secure access to data and applications based on dynamic security policies reacting to access request specifics, as opposed to the network from where access originates.

The Zero Trust (ZT) architecture is a modern concept shaping cybersecurity in the public and private sectors. The growing use of SaaS applications, migration to cloud-based architecture, a rising number of remote employees, and bring-your-own-device (BYOD) have rendered perimeter-based security obsolete. The concept of a network perimeter where those outside of the enterprise's control are malicious and insiders are trustworthy — is no longer a viable approach to cybersecurity.
