🔒 AWS is introducing flat-rate pricing plans for CloudFront that bundle global CDN delivery with built-in security (WAF, DDoS protection), Route 53 DNS, CloudWatch Logs ingestion, serverless edge compute, and monthly S3 storage credits. Plans eliminate overage charges so traffic spikes or attacks won’t trigger surprise fees. Tiers include Free, Pro ($15), Business ($200) and Premium ($1,000), and pay-as-you-go remains an option.

⚠️ Microsoft reported that the Aisuru botnet launched a massive DDoS attack against a public Azure IP in Australia, peaking at 15.72 Tbps and nearly 3.64 billion packets per second. The traffic originated from over 500,000 IP addresses and consisted of extremely high-rate UDP floods with minimal source spoofing. Microsoft noted the bursts used random source ports, which aided traceback and provider enforcement. Azure's mitigations absorbed the attack without a reported widespread outage.

🛡️ ENISA's study of 586 public administration incidents found DDoS attacks made up roughly 60% of events, with 63% attributed to hacktivist groups. Central government incidents accounted for 69% of the total, while data breaches (17%) and ransomware (10%) caused disproportionate disruption. ENISA warns the sector's low maturity and recent inclusion in NIS2 increase risk and recommends CDNs/WAFs for DDoS mitigation, MFA/PAM/DLP for data protection, and EDR, segmentation and backups to combat ransomware.

🔍 This post investigates why Cloudflare returned ENHANCE_YOUR_CALM for internal HTTP/2 traffic and traces the issue to an easy-to-make Go client behavior. An incorrect pattern where a response is closed without being fully read caused the Go HTTP/2 library to emit RST_STREAM and PING frames in quick succession, triggering PING-flood mitigations. The fix: always drain response bodies (for example, io.Copy(io.Discard, resp.Body)) before calling Close().

🛡️ Hezi Rash is a Kurdish nationalist hacktivist collective formed in 2023 that has escalated to coordinated DDoS campaigns targeting entities perceived as hostile to Kurdish or Muslim communities. Their public rhetoric mixes nationalism, religion, and activism, and they have claimed attacks in response to symbolic provocations such as an anime scene depicting a burning Kurdish flag. Targets reported include anime platforms, media outlets, NGOs, and government services, causing intermittent service disruptions and demonstrating growing technical sophistication.

🔒 Cloudflare patched two QUIC ACK-handling vulnerabilities (CVE-2025-4820, CVE-2025-4821) affecting its open-source quiche library and services using it. The flaws—missing ACK range validation and an Optimistic ACK attack—could let a malicious peer inflate server send rates, driving CPU and network amplification. Cloudflare implemented ACK range enforcement and a dynamic, CWND-aware skip frequency; quiche versions prior to 0.24.4 were affected.

🛡️ Cloudflare assisted the Moldovan Central Election Commission (CEC) during the September 28, 2025 parliamentary vote, rapidly onboarding election sites and deploying mitigations under the Athenian Project. On election day Cloudflare mitigated over 898 million malicious requests across multiple DDoS waves, including a peak of 324,333 rps, keeping official result reporting and civic sites online. Automated defenses and coordination with STISC ensured no interruptions to public access and authoritative information.

🛡️ Aisuru, first identified in August 2024, has been retooled from launching record DDoS assaults to renting hundreds of thousands of compromised IoT devices as residential proxies. Researchers warn the change powers a massive proxy market that is being used to anonymize large-scale content scraping for AI training and other abuses. The botnet — roughly 700,000 devices strong — previously produced multi‑terabit attacks that disrupted ISPs and damaged router hardware. Industry and law enforcement are sharing blocklists and probing proxy reseller ecosystems tied to the infections.

🌐 In Q3 2025 Cloudflare observed a wide range of Internet disruptions affecting governments, carriers, and infrastructure worldwide. Incidents included government-directed shutdowns in Sudan, Syria, Iraq, Venezuela, and Afghanistan; submarine and terrestrial cable cuts; power outages; a major earthquake; a targeted cyberattack; and technical failures such as Great Firewall anomalies and Starlink outages. The post synthesizes observed traffic losses using Cloudflare Radar metrics.

🚀 AWS Global Accelerator now supports application endpoints in two additional AWS Regions — Asia Pacific (Thailand) and Asia Pacific (Taipei) — bringing total coverage to thirty-three Regions. The service offers static IP addresses, congestion-free AWS network routing, edge DDoS protections, and continuous health monitoring to enable deterministic multi-region failover without DNS dependencies. To use the new Regions, configure endpoints such as Application Load Balancers, Network Load Balancers, Amazon EC2 instances, or Elastic IPs and review the Global Accelerator documentation.

🛡️ The German federal procurement portal was rendered inaccessible for almost a week by a sustained DDoS campaign; the service was restored Tuesday afternoon. Security analysts attribute the disruption to the pro‑Russian hacker group NoName057(16), which has previously targeted critical infrastructure, authorities and companies in Western countries. The attacks, confirmed as DDoS by observers, overwhelmed servers with a flood of requests. The Federal Office for Information Security (BSI) said it was informed of the incident. The portal, dtvp.de, is a central nationwide platform for electronic Q&A and bid submissions in public tenders.

⚠️ Aisuru, an IoT botnet derived from Mirai, generated a nearly 29.6 Tbps DDoS surge on Oct. 8, 2025, briefly disrupting major US ISPs and online gaming platforms. Logs show most attack traffic originated from compromised home routers, IP cameras and DVRs on networks operated by AT&T, Comcast, Verizon, T‑Mobile and Charter. TCPShield reported over 15 Tbps of junk traffic, and researchers warn Aisuru now operates as both a DDoS engine and a residential proxy network.

🛰️ Aisuru, now the world’s largest IoT botnet, is drawing the majority of its attack volume from compromised consumer devices hosted by U.S. ISPs such as AT&T, Comcast and Verizon. In early October the botnet briefly generated a near‑30 terabit-per-second traffic flood, underscoring its rapidly expanding scale and destructive reach. The attacks have targeted gaming-focused networks and protection providers, causing widespread collateral congestion and forcing providers to reassess outbound mitigation. Built on Mirai-derived code, Aisuru is also being marketed as a residential proxy service, complicating attribution and remediation.

⚠️ ENISA reports the EU cyber threat landscape has worsened, identifying ransomware as the single most damaging threat due to widespread encryption and costly recoveries. By frequency, DDoS incidents dominate (77% of reported cases), though they typically cause shorter-lived outages. The agency's analysis of 4,875 incidents from July 2024 to June 2025 also highlights concentrated attacks on public administration and a rapid rise in AI-assisted social engineering.

🌐 Cloudflare observed a nationwide Internet shutdown in Afghanistan on 29 September 2025 that began with a brief fixed-line interruption around 11:30 UTC and escalated to a full fiber-optic cut shortly after 12:30 UTC. HTTP requests, DNS queries (1.1.1.1) and total bytes dropped to zero at a national level, while mobile providers showed brief, partial connectivity. The outage removed the majority of announced IPv4 and IPv6 prefixes and threatens banking, customs, emergency communications, television and radio services.

🛡️ Cisco firewalls were exploited in active zero-day attacks that delivered previously undocumented malware families including RayInitiator and LINE VIPER by chaining CVE-2025-20362 and CVE-2025-20333. Infrastructure and cloud environments faced major pressure this week: Cloudflare mitigated a record 22.2 Tbps DDoS while misconfigured Docker instances enabled ShadowV2 bot operations. Researchers also disclosed Supermicro BMC flaws that could allow malicious firmware implants, and ransomware actors increasingly abuse exposed AWS keys. Prioritize patching, firmware updates, and cloud identity hygiene now.

🔒 AWS WAF's Targeted Bot Control, Fraud, and DDoS Prevention Rule Group are now available in Asia Pacific (Taipei), Asia Pacific (Bangkok), and Mexico (Central). These managed rule groups deliver detection and mitigations for sophisticated bots, application-layer DDoS, and account-takeover attacks at the web edge. Customers can deploy them to improve application resilience, reduce fraudulent activity, and limit resource consumption during attack campaigns.

🛡️ Darktrace researchers uncovered a ShadowV2 campaign that leverages exposed Docker APIs on AWS EC2 to provision containers and run a Go-based remote access trojan, converting misconfigured cloud containers into distributed DDoS nodes. The attackers create containers on victim hosts rather than importing malicious images, likely to reduce forensic traces, and use the Python Docker SDK to interact with exposed daemons. ShadowV2 operators employ advanced techniques including HTTP/2 rapid reset and Cloudflare evasion, and the platform includes APIs, a Tailwind/FastAPI UI and operator logins that turn botnet control into a commercialized DDoS-as-a-Service offering.

🛡️ The Gcore Radar Q1–Q2 2025 report shows a 41% year-on-year rise in DDoS attacks, with total incidents reaching 1.17 million and a record 2.2 Tbps peak. Attacks are getting longer, more sophisticated, and increasingly multi-vector, with technology (≈30%) overtaking gaming (19%) as the primary target. Gcore emphasizes integrated WAAP and global filtering capacity to mitigate these risks.

🛡️ Darktrace has uncovered a ShadowV2 campaign that combines a GitHub CodeSpaces-hosted Python command-and-control framework, a Docker-based spreader, and a Go-based RAT to operate a DDoS-as-a-service platform. Attackers target exposed Docker daemons on AWS EC2 to build on-victim images and deploy malware via environment variables, reducing forensic artifacts. The platform exposes an OpenAPI-driven UI and multi-tenant API enabling HTTP/HTTP2 floods, UAM bypasses, and other configurable attack options.
