Malicious DDoS attacks have risen by 150%
Radware, a leading provider of cyber security and application delivery solutions, released its 2022 Global Threat Analysis Report. The full-year report leverages intelligence provided by network and application attack activity sourced from Radware’s Cloud and Managed Services, Global Deception Network and threat research team.
“‘The operative word for the global threat landscape in 2022 is ‘more,’” said Pascal Geenens, director of threat intelligence for Radware. “Compared to 2021, there were not only more DDoS attacks in terms of sheer number, but they were also more powerful, frequent and complex, spanning more attack vectors.”
“The surge can be attributed in part to digitalization, the war in Ukraine, and a long-tail of new vulnerabilities and exposed services driven by work-from-home remote access during Covid. The ongoing tensions between major world powers have also led to a rise in state-sponsored cyberattacks and espionage activities.”
Global attack trends: the unrelenting rise of DDoS
The global DDoS landscape is rapidly evolving. The report notes that, in 2022, DDoS attack profiles were redefined by gains in number, frequency, volume, power, duration and complexity.
Number of attacks: In 2022, the number of DDoS attacks grew 150% on a global basis compared to the previous year. The number of attacks in the Americas rose even faster, increasing 212% compared to 2021. More than half of the attacks were aimed at organizations in EMEA. The Americas accounted for 35% of the attacks while 7% of the attacks targeted APAC organizations.
Attack frequency: The frequency of DDoS attacks also saw a significant and concerning uptick. Globally, organizations mitigated an average of 29.3 attacks per day during the fourth quarter of 2022, 3.5 times more compared to 8.4 attacks per day at the end of 2021. Attacks in EMEA grew even faster than the global average and outpaced both the Americas and APAC. Organizations in EMEA averaged 45 attacks per day in the fourth quarter of 2022, four times more compared to 11.3 attacks per day during the same period in 2021.
Attack volume: While the total global attack volume recorded in 2022 was 4.44PB, an increase of 32% compared to 2021, the Americas faced the heftiest increases. Last year, attack volumes in the Americas outpaced global volumes, growing 110% compared to 2021. While EMEA topped the Americas in frequency of attacks, it saw total attack volume decline.
Attack power: Globally, the largest recorded attack in 2022 was 1.46Tbps, which is 2.8 times larger than the largest attack recorded in 2021.
Attack duration: The longest attacks in 2022 ranged between 100 and 250Gbps on a global basis, where on average the attacks lasted 66 hours or 2.75 days.
Attack complexity: DDoS attacks continue to increase in complexity. Attackers typically leverage multiple and dissimilar vectors to increase the impact and make attack mitigation harder. On a global basis in 2022, attacks above 1Gbps on average had more than two dissimilar attack vectors per attack, which doubled in complexity for attacks above 10Gbps. Attacks above 100Gbps had, on average, more than nine dissimilar attack vectors with the most complex attacks leveraging 38 dissimilar attack vectors.
“In 2023, the democratization of DDoS and patriotic 'hacktivism' will continue to drive an increase in smaller, more frequent attacks – a trend we are already seeing in the increased frequency of lower volume attacks in EMEA,” said Geenens.
“At the same time, expect the cybercrime underground to become even better organized and funded in its pursuit of hard-hitting attacks. Attackers are always looking for new more sophisticated ways to advance their cyber agendas. As a result, organizations find themselves in an escalating state of risk, trying to defend themselves against next-generation threats.”
Most attacked industries
On a global basis, the report discovered that finance was the most attacked industry in 2022, with 53% of the overall attack activity, followed by technology (20%) and healthcare (11%). Even on a geographic distribution, finance and technology were among the industries shouldering the brunt of the DDoS activity.
In America, finance represented 32% of the attack activity, followed by healthcare (24%) and technology (17%).
In EMEA, finance (71%) also topped the list as the most-attacked industry, followed by technology (16%) and government (4%).
In APAC, technology was the most attacked industry, with 70% of the attack activity, followed by finance (9%) and government (8%).
Web application attacks
Web application and API attacks grew exponentially in 2022. Web application and API attacks increased 128% year over year, significantly out pacing the 88% increase in attacks between 2020 and 2021. Predictable resource location attacks accounted for almost half of the attack activity. Together, code injection (14%) and SQL injection (11%) attacks represented another quarter of the web application attacks.
The most attacked industries were retail and wholesale trade (25%), followed by high-tech (20%), and carriers (15%), together accounting for 60% of blocked web application attacks.
