Link11 has released findings from its DDoS Report for 2020, which reveal that DDoS attacks reached a record high during the pandemic as cybercriminals launched new and increasingly complex attacks.

Key findings from analysis for the report, which was carried out by the Link11 Security Operations Center (LSOC) in combination with OSINT, include:

As the attack surfaces for companies have increased in size and complexity due to the digital transformation triggered by the pandemic, DDoS attackers have adapted to these trends. In addition to VPNs and APIs, attackers also focused on CRMs, databases, and email and web servers, which attacks extending across all layers.

The 2020 DDoS report revealed that cybercriminals began ramping up their DDoS extortion efforts in the second half of the year. Extortionists posing as Fancy Bear, Cozy Bear, Armada Collective, and Lazarus Group mainly targeted operators of critical infrastructure and providers of financial services, eCommerce, and hosting services. Often using large-volume warning attacks of over 50 Gbps, the extortionists pressured companies to pay ransoms ranging from five to 15 Bitcoins.

The report also suggests that DDoS attacks will continue to be prevalent through 2021. Digital corporate IT, cloud services and APIs will continue to experience heavy DDoS fire and companies should include the threat of DDoS extortion in their risk assessments.
