- A major NHL incident recently revealed a large -scale DDOS attack.
- The attack increased from 67GBPS to about 1Tbps in twenty minutes
- Multistory strikes used UDP, SYN, IP and TCP flood techniques
Cyber security firm Qurator Labs has claimed that it has successfully reduced the largest DDOS attack so far recorded in 2025.
The April 3 attack targeted an anonymous online betting organization, which was going on for about 90 minutes, which started from 11:15, with a jump of 67GBPS, below 1TBPS on 965GBPS by 11:23, and by 11:36.
The activity then gradually decreased to 549GBPS, until 12:41, ended shortly after the attack. The DDOS attack was polymorphic in nature, with a peak of 965GBPS in the UDP flood, 229GBPS in SYN Flood, 214GBPS in IP floods, and 169GBPS in TCP floods.
Sports organizing are the major goals
Quator noted that the attack took place on the same day when NHL Star Alexander Ovechin scored his 892nd goal by tying the record of Ven Greatzaki for a long time. Ovechin’s achievement was likely to trigger for the attack as the online betting field is particularly weak during major sports events.
A similar attack pattern was seen during the 2024 UEFA European Football Championship held in Germany, where Spikes also targeted online betting sites in DDOS activity.
“This new phenomenon is a clear reminder that major industry-specific events can be exploited by malicious actors. Companies working with them, such as online betting platforms, should prepare them in advance to protect their digital infrastructure, when attention is at its peak,” said the main technology officer of the curator labs.
Betting platforms remain a major goal for such coordinated attacks, with large -scale audiences online with major sports moments.
Other notable sports programs to be held this year, which may prove to be a target for similar DDOS strikes, include the FIFA Club World Cup in the United States and the World Athletics Championship in Tokyo.
