DDOS Attack Protection By Tether

Poor DDOS Attack Protection Led to DDOS Attack on Tether Website!

Tether CTO, Paolo Ardoino, confirmed that the Tether website is currently undergoing a DDOS attack due to poor DDOS attack protection. On Jun 18, 2022, the number of requests for the website increased from 2,000 to 8,000,000 every five minutes. The chart below represents the increase in requests.

Tether’s DDOS Attack Protection System

Paolo Ardoino confirmed that the DDOS attack is now weakened, but Tether is “leaving the ‘I’m under attack mode’ enabled” for DDOS attack protection and to diminish further risk. Tether's CTO further stated that the additional security move “won’t affect the ability to redeem.”

DDOS Attack Protection: Under Attack Mode

Cloudflare’s DNS management provides a service titled “I’m under attack mode”, and its job is to provide websites with DDOS attack protection. It does so by forcing users to complete an additional step before they can access the website. For human users viewing the website through a standard web browser, this shows as a few-second delay. Meanwhile, their browser completes a javascript challenge.

How Does DDOS Attack Protection Work?

If the user’s browser couldn’t complete the javascript challenge, the user may have to complete a captcha to access the website. However, DDOS attacks are often executed using remote servers, which make requests on the website from outside of a browser. These DDOS attack methods will fail the challenge request and get kicked before reaching the server. Cloudflare handles all this excess demand from DDOS attacks and leaves the client website free to perform tasks as usual, which is an efficient way of DDOS attack protection. 

Tether CTO Explains The DDOS Attack Situation

Tether's CTO also confirmed that the reason for the DDOS attack was that “it takes a bit of time for the auto-scale to adjust.” Regarding this, he points to the server's capability behind the website to manage resources and cope with the unexpected increase in requests. Earlier on Saturday, Tether’s CTO tweeted: “It will be a long weekend,” but it is unlikely he expected it to be due to a DDOS attack protection mechanism on Tether’s website.
