Background for this topic.
Denial of service (DoS) is an attack that makes a system, network, or application unavailable by exhausting resources or triggering failure. Floods can consume bandwidth, connection state, CPU, memory, or request-processing capacity; a software defect may instead be exploited to crash a service. A distributed denial-of-service (DDoS) attack generates traffic from many systems, increasing volume and complicating source-based blocking. The material security impact is loss of availability for users and dependent services, including websites, APIs, DNS, and operational systems.
Mitigation should match the bottleneck. Rate limits, request validation, connection protections, caching, and service isolation can reduce application and state-exhaustion attacks; volumetric traffic generally needs filtering or absorption upstream of the network. Monitoring should distinguish abnormal request patterns from ordinary load and alert on saturation, while tested failover, traffic diversion, and restoration procedures limit outage duration. Vulnerability management and timely patching reduce DoS caused by remotely triggerable crashes, but do not replace capacity planning and resilience testing.
Microsoft warns enterprises should pay attention to a new botnet used to launch DDoS attacks on private Minecraft Java servers.
A new cross-platform malware botnet named 'MCCrash' is infecting Windows, Linux, and IoT devices to conduct distributed denial of service attacks on Minecraft servers. [...]
Microsoft on Thursday flagged a cross-platform botnet that's primarily designed to launch distributed denial-of-service (DDoS) attacks against private Minecraft servers
Cops give denial-of-service sites an extra special denial of service Police around the globe have seized as many as 50 internet domains said to be involved in tens of millions of distributed-denial-of-service (DDoS) attacks worldwide. Seven people were collared during the swoop.…
Sweeping operation took down around 50 popular DDoS platforms, just one of which was used in 30M attacks, Europol says.
In DDoS Protection, Gcore uses the bundle of XDP and regular expressions (regex). This article will explain why Gcore started using this solution (regex in XDP) and how they bound them via a third-party engine and API development. [...]
Six also charged in connection with booter services
The U.S. Department of Justice (DoJ) on Wednesday announced the seizure of 48 domains that offered services to conduct distributed denial-of-service (DDoS) attacks on behalf of other threat actors, effectively lowering the barrier to entry for malicious activity
The US Department of Justice has seized 48 Internet domains and charged six suspects for their involvement in running 'Booter' or 'Stresser' platforms that allow anyone to easily conduct distributed denial of service attacks. [...]
The U.S. Department of Justice (DOJ) today seized four-dozen domains that sold “booter” or “stresser” services — businesses that make it easy and cheap for even non-technical users to launch powerful Distributed Denial of Service (DDoS) attacks designed knock targets offline. The DOJ also charged six U.S. men with computer crimes related to their alleged ownership of the popular DDoS-for-hire services.
