Lumen mitigates 14% more DDoS attacks in Q2 than in Q1
August 17, 2021
Potential attack surface is growing as criminals look to disrupt, profit off DDoS and Ransom DDoS attacks

DENVER, Aug. 17, 2021 /PRNewswire/ -- The second quarter of 2021 was particularly active for cybercriminals, and many high-profile events dominated the headlines. To help businesses, government, clients and the industry better understand the security landscape, Lumen Technologies (NYSE: LUMN) today released its quarterly Distributed Denial of Service (DDoS) report for Q2 2021.

Experience the interactive Multichannel News Release here:


"We are witnessing a rise in ransom DDoS attacks, where cybercriminals threaten to execute a DDoS attack unless a ransom is paid," said Mike Benjamin, Lumen vice president of security and Black Lotus Labs. "The threat actors aren't just looking to disrupt – they are frequently running criminal campaigns looking to make a profit. Some businesses are purely digital, and that makes them more vulnerable, because when the potential attack surface increases, this also increases the opportunity for threat actors. The best defense is a DDoS mitigation service that stops these attacks before they happen."

22 ….. Percentage increase in unique C2s tracked across Gafgyt and Mirai
