CDNetworks Safeguards Cryptocurrency Exchange: Defying a 1.025 Tbps Blockchain DDoS Onslaught

SINGAPORE – 25/01/2024 – (SeaPRwire) – In a remarkable display of cybersecurity prowess, CDNetworks, a dominant force in the APAC region delivering edge as a service, thwarted a relentless Blockchain DDoS attack targeting a cryptocurrency exchange on January 9, 2024, reaching a staggering peak of 1.025Tbps. Coincidentally, this assault unfolded on the eve of a groundbreaking moment as the U.S. SEC granted approval for the first U.S.-listed Bitcoin Exchange-traded funds (ETFs). This audacious attack, directed at a specific cryptocurrency exchange with exceptionally high peak volumes, has heightened global awareness for organizations in the cryptocurrency sector regarding potential threats.

The assailants employed over 400,000 IP addresses and a significant botnet network arsenal to launch an offensive on the API interface of the cryptocurrency exchange. This strategic assault, synchronized with the approval of the first U.S.-listed ETFs by the U.S. SEC, signifies a pivotal moment in the landscape of blockchain cybersecurity threats.

In a statement, Doyle Deng, Head of Global Marketing and Product at CDNetworks, emphasized, “The probability of an attack was notably high, especially considering the timing on the eve of the US SEC’s approval of Bitcoin ETFs. Collaborating with us to implement our Expert Emergency Response services or Major Event Support could have entirely averted the situation.” He lauded the service team for their vigilant monitoring and collaborative efforts with clients, ensuring a swift and effective response to the DDoS attack.
