- 6Tbps DDoS Attack on Gcore Among World’s Largest Incidents
- Gcore’s defenses absorbed the flood using over 210 global points of presence
- More than half of malicious traffic came from unsecured networks in Brazil
A gaming hosting provider has reportedly been hit by one of the largest distributed denial of service (DDoS) attacks on record.
The attack ranks among the top ten DDoS incidents in history, revealing the growing risks faced by online service providers and gaming infrastructures.
The blockbuster company, Gcore, claims the event was a “short-lived volumetric flood” lasting between 30 and 45 seconds and peaking at 6 Tbps with 5.3 billion packets per second.
A short but powerful DDoS attack
The attack primarily used the UDP protocol, a common choice for overwhelming targets with traffic.
Gcore’s analysis found that 51% of malicious data came from Brazil and almost 24% from the United States, suggesting widespread exploitation of insecure networks in these regions.
The attack was consistent with activity from the AISURU botnet, which has been linked to several recent high-profile cyberattacks.
The scale and regional distribution reflect a worrying evolution in the capacity of botnets, capable of launching high-intensity, short-duration strikes.
While this particular attack was successfully mitigated, the incident reflects a broader trend in which cybercriminals deploy short DDoS bursts to test the resilience of hosting and enterprise networks.
These preliminary attacks are often the precursors to more complex operations that may involve malware infiltration or attempts to circumvent ransomware protection systems.
Gcore said its global DDoS protection system absorbed the 6 Tbps flood without interruption, using more than 210 PoPs worldwide and filtering capacity of more than 200 Tbps.
Its data also shows a 41% increase in DDoS activity in a single quarter, with the technology and gaming sectors among the most frequently attacked.
However, experts warn that this event demonstrates a dangerous shift in cyberwarfare tactics, where the goal is not only to disrupt but also to probe and exploit infrastructure weaknesses.
For web hosting providers, the implications go beyond downtime and bandwidth saturation.
Increasingly, DDoS attacks are part of multi-vector campaigns that can involve data theft, malware evasion, and ransomware protection issues.
“This incident highlights a continued escalation in the scale and sophistication of DDoS attacks,” said Andrey Slastenov, chief security officer at Gcore.
“Without strong, adaptive protection, organizations in the technology, hospitality and enterprise sectors remain at risk. »
