⚠️ 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.

🔒 The US Secret Service has seized and dismantled a network of electronic devices across the New York tristate area that could be used to disrupt cellular service ahead of the United Nations General Assembly in New York City. Authorities recovered 300 co-located SIM servers and 100,000 SIM cards, equipment capable of enabling DoS attacks, disabling towers and facilitating anonymous encrypted communications. The operation was led by the agency’s Advanced Threat Interdiction Unit, which says early analysis identified contacts between individuals tied to the network and known nation-state threat actors; the investigation remains ongoing with multiple federal and local partners.

🚨 Cloudflare reported that it mitigated a massive volumetric DDoS attack that peaked at 22.2 Tbps and 10.6 billion packets per second, lasting roughly 40 seconds. The traffic surge equated to streaming about one million 4K videos simultaneously and generated a packet rate roughly equal to 1.3 web page refreshes per person on Earth. Such extreme packet velocities strain firewalls, routers, and load balancers even where aggregate bandwidth may be handled. Cloudflare has provided limited technical detail on this and recent record attacks.

🚨 ShadowV2 is a new botnet campaign that converts misconfigured Docker containers on AWS into a DDoS-for-hire platform. Darktrace’s analysis shows attackers exploiting exposed Docker daemons via the Python Docker SDK, building containers on victims' hosts and deploying a Go-based RAT that polls operators and launches large HTTP floods. The operation is highly professionalized, offering APIs, dashboards, operator logins and modular attack options that make DDoS easily rentable.

⚠️ Researchers at Darktrace disclosed ShadowV2, a DDoS-focused botnet that exploits misconfigured Docker daemons on AWS EC2 instances to deploy a Go-based RAT and enlist hosts as attack nodes. The campaign uses a Python spreader to spawn an Ubuntu setup container, build a custom image, and run an ELF payload that checks in with a Codespaces-hosted C2. Operators leverage HTTP/2 Rapid Reset floods, a Cloudflare UAM bypass via ChromeDP, and a FastAPI/Pydantic operator API, signaling a modular DDoS-for-hire service.

🛡️ DNS Armor is a cloud-native DNS security service from Google Cloud, built in partnership with Infoblox, that provides preemptive detection and mitigation of DNS-based threats for Google Cloud workloads. By intercepting internet-bound DNS queries and inspecting them in real time with Infoblox Threat Defense, it identifies malicious and high-risk domains, C2 activity, DNS tunneling, DGA patterns and evasive techniques such as fast-flux, and forwards detailed logs to Cloud Logging, Security Command Center, or SIEMs. Delivered as a turnkey managed service with no VMs and no impact to Cloud DNS, DNS Armor is enabled at the project level for granular protection and is available now in preview.

🚨 A European DDoS mitigation provider was hit by a massive packet-rate flood that peaked at 1.5 billion packets per second. FastNetMon detected the assault, which originated from thousands of compromised customer premises devices, including IoT units and MikroTik routers across more than 11,000 networks. The malicious traffic was primarily a UDP flood and was mitigated in real time using the customer's scrubbing facility, ACLs on edge routers, and packet inspection. FastNetMon warned this trend requires ISP-level filtering to prevent large-scale abuse of consumer hardware.

🛡️ Cloudflare said it automatically mitigated a record-setting volumetric DDoS attack that peaked at 11.5 Tbps and reached 5.1 billion packets per second; the UDP flood lasted roughly 35 seconds and reportedly originated largely from Google Cloud. The company reported it has autonomously blocked hundreds of hyper‑volumetric L3/4 attacks in recent weeks, underscoring a sharp surge in such events. Security researchers warn these massive traffic floods can be used as a smoke screen for follow-on targeted exploits.

🛡️ Cloudflare says it blocked the largest recorded volumetric DDoS attack, peaking at 11.5 Tbps. The UDP flood, which Cloudflare attributes mainly to traffic originating from Google Cloud, lasted roughly 35 seconds and was part of a broader surge of hyper‑volumetric events. The mitigation highlights Cloudflare's automated scaling and defensive capabilities against short, extremely high‑bandwidth assaults.

🛡️ Cybersecurity teams report coordinated campaigns exploiting exposed infrastructure and known flaws to monetize or weaponize compromised devices. Attackers have abused CVE-2024-36401 in GeoServer to drop lightweight Dart binaries that monetize bandwidth via legitimate passive-income services, while the PolarEdge botnet and Mirai-derived gayfemboy expand relay and DDoS capabilities across consumer and enterprise devices. Separately, TA-NATALSTATUS targets unauthenticated Redis instances to install stealthy cryptominers and persistence tooling.

🛡️ FortiGuard Labs reports the resurgence of a Mirai-derived IoT malware family, publicly known as “Gayfemboy,” which reappeared in July 2025 targeting vulnerabilities in DrayTek, TP-Link, Raisecom, and Cisco devices. The campaign delivers UPX-packed payloads via predictable downloader scripts named for product families and uses a modified UPX header and architecture-specific filenames to evade detection. At runtime the malware enumerates processes, kills competitors, implements DDoS and backdoor modules, and resolves C2 domains through public DNS resolvers to bypass local filtering. FortiGuard provides AV detections, IPS signatures, and web-filtering blocks; organizations should patch and apply network defenses immediately.

🛡️ In episode 431 of the Smashing Security podcast, Graham Cluley and guest Allan Liska examine a high-profile cloud-billing fraud in which a crypto influencer calling himself CP3O racked up millions in unpaid cloud costs through cryptomining schemes. They also highlight the growing threat of EDR‑killer tools that can silently disable endpoint protection to aid attackers. The show includes lighter segments on the Internet Archive’s Wayforward Machine and a visit to Mary Shelley’s grave, and carries a content warning for mature language and themes.
