🚨 The U.K.'s National Cyber Security Centre (NCSC) warns of sustained disruptive DDoS activity from pro‑Russian hacktivists, notably NoName057(16), which operates the crowdsourced DDoSia platform that mobilises volunteers and offers rewards. Despite arrests and server takedowns during Operation Eastwood, the group has re-emerged and continues to target critical infrastructure, local government and OT systems. The NCSC advises strengthening upstream ISP/CDN protections, designing for rapid scaling, rehearsing response plans for graceful degradation, and continuous testing to reduce downtime and recovery costs.

⚠️ The UK National Cyber Security Centre (NCSC) has issued an alert about ongoing disruptive cyber activity by Russian-aligned hacktivist groups targeting UK organisations, with local government and critical national infrastructure singled out. The campaigns mainly use denial-of-service (DoS/DDoS) attacks to overwhelm websites and online systems, taking services offline. The advisory highlights groups such as NoName05716, their coordination via Telegram and the hosting of tooling on GitHub, and urges organisations to review DoS protections, strengthen resilience and engage with NCSC threat collection.

⚠️ The controversial ICE List doxxing site, launched after an alleged DHS whistleblower provided details on thousands of ICE and Border Patrol officials, has been taken offline by a sustained DDoS attack. Founder Dominick Skinner reported that overwhelming traffic appears to originate from Russian IP addresses routed through proxies, complicating attribution. Skinner and his team are attempting server migrations to restore access but expect the site to remain a target.

🚨 Black Lotus Labs said it null-routed traffic to more than 550 command-and-control nodes tied to the AISURU/Kimwolf botnet after detecting rapid growth beginning in early October 2025. Researchers attribute the expansion to a malicious ByteConnect SDK delivered to unsanctioned Android TV devices and proxy services that expose Android Debug Bridge (ADB). The botnet, leveraged for DDoS and residential proxy leasing, has infected more than two million devices and has been linked to hosting providers and proxy marketplaces where compromised nodes were offered for sale.

🔍 This analysis traces how the Aisuru and Kimwolf botnets turned millions of unsecured Android TV streaming boxes into residential proxies and DDoS participants. Investigators linked proxy traffic and control infrastructure to a Utah hosting firm, Resi Rack, a Discord marketplace (resi.to), and vendors including Plainproxies/ByteConnect and Maskify. Operators hardened control with the Ethereum Name Service to evade takedowns. Owners of affected TV boxes are urged to disconnect and replace them.

🛡️ Researchers report the Kimwolf Android botnet — an Aisuru variant — has grown to nearly two million infected hosts by abusing residential proxy services to reach devices on internal networks. The malware scans for unauthenticated Android Debug Bridge (ADB) endpoints on ports such as 5555 and delivers payloads via telnet/netcat, often targeting low-cost Android TV boxes. Affected devices are used for DDoS, proxy resale, and ad-fraud via third-party SDKs; mitigation includes wiping compromised boxes and preferring Google Play Protect-certified hardware from reputable OEMs.

🔒 NETSCOUT's Arbor Edge Defense (AED) complements CDN-based DDoS mitigation by providing inline, on-premises protection for attacks that cloud scrubbing can miss. AED uses AI/ML-driven stateless packet processing and ATLAS threat intelligence to address application-layer, TCP state-exhaustion, and outbound threats. Together, CDN protections and AED form a layered, adaptive defense-in-depth strategy that preserves bandwidth and safeguards availability.

🛡️ DDoS attacks are widespread and varied, yet persistent myths can lead organizations to underprepare. This article debunks five common misconceptions — that attacks only hit large companies, that DDoS is always high-volume flooding, that NGFWs or cloud-only solutions are sufficient, and that AI/ML is unnecessary — and explains modern multivector and application-layer tactics. Defenders are advised to deploy hybrid, AI-enabled, and stateless mitigation to protect availability.

⚠️ Taiwan's National Security Agency reported that Chinese cyberattacks targeting the island's critical infrastructure rose 6% in 2025, averaging 2.6 million attacks per day. The assaults mainly focused on the energy sector, hospitals, banks and emergency services, and extended to the semiconductor industry, including TSMC. Attackers employed large-scale denial-of-service and man-in-the-middle techniques to disrupt operations and exfiltrate data. Many incidents reportedly coincided with Chinese military exercises and high-profile political events, while Beijing denies involvement.

🛡️ Synthient reports the Kimwolf Android botnet has compromised more than two million devices by tunneling through residential proxy networks and embedded SDKs. The campaign, active since August 2025 and linked to AISURU by QiAnXin XLab, exploits exposed Android Debug Bridge (ADB) services—67% of infected devices had unauthenticated ADB enabled. Operators monetize infections via app installs, selling residential proxy bandwidth and DDoS services; the main payload listens on port 40860 and connects to 85.234.91[.]247:1337 for commands.

🛡️ Synthient and other researchers describe the explosive growth of the Kimwolf botnet, which has infected more than two million devices globally, concentrated in Vietnam, Brazil, India, Saudi Arabia, Russia and the United States. Kimwolf abuses residential proxy services — notably China-based IPIDEA — to tunnel back into home networks and compromise devices such as unofficial Android TV boxes and digital photo frames. The malware leverages weak proxy DNS handling and factory-enabled Android Debug Bridge (ADB) to gain unauthenticated administrative access, then installs proxy and DDoS-capable payloads. Researchers advise removing suspect TV boxes, isolating guests on a Guest Wi‑Fi network, and preferring reputable brands to reduce exposure.

🔴 La Poste's main website and multiple digital services were taken offline by a major DDoS attack on Monday, and access remained impaired as of Wednesday morning. While email (laposte.net) and Digiposte reportedly stayed operational, online banking, the La Poste app and digital identity services were described as "temporarily inaccessible." The incident also disrupted physical operations, with some Paris post offices turning customers away. La Poste says teams are fully mobilized while analysts warn the timing suggests possible state-sponsored or hacktivist motives.

⚠️ France’s national postal service, La Poste, experienced a widespread network outage lasting more than twelve hours that affected its website, mobile app, digital document service Digiposte, and a digital ID service. Counter services remained operational, but the banking arm, Banque Postale, saw its app and online services go offline. Payments and SMS verification reportedly continued to function. Officials have not confirmed a cause; Le Monde Informatique has cited a suspected DDoS attack.

French media cited a suspected DDoS attack; La Poste has not provided a restoration timeline.

🔒 The Danish Defence Intelligence Service (DDIS) publicly attributed two separate cyber operations to Russian-linked actors. It said a pro-Russian group known as Z-Pentest carried out a destructive intrusion against a Danish water utility in 2024, while NoName057(16), an actor with ties to the Russian state, mounted disruptive DDoS attacks against Danish websites ahead of municipal and regional elections in November. Danish authorities characterized the incidents as part of a broader pattern of state-aligned cyber coercion and disruption.

🛡️ The Danish Defence Intelligence Service (DDIS) said on December 18, 2025 that Russian-aligned actors were responsible for recent destructive and disruptive cyber activity against Denmark. The agency named pro‑Russian hacktivist groups Z‑Pentest for a destructive 2024 intrusion at a water utility and NoName057(16) for DDoS campaigns targeting websites ahead of the 2025 municipal and regional elections. DDIS assessed both groups have links to the Russian state and are being used as instruments of a hybrid campaign to create insecurity and penalise countries supporting Ukraine. The statement followed a global advisory, co-signed by 23 law enforcement and intelligence bodies, which catalogued related TTPs.

🛡️ Researchers at QiAnXin XLab disclosed a large-scale NDK-compiled botnet dubbed Kimwolf that has infected at least 1.8 million Android-based TVs, set-top boxes, and tablets across multiple countries. The infrastructure issued an estimated 1.7 billion DDoS commands over a three-day period in November 2025 and supports 13 UDP/TCP/ICMP attack methods while also offering proxy forwarding, reverse shell, and file management functions. Operators responded to repeated C2 takedowns by moving to ENS domains and deploying an EtherHiding technique that resolves C2 IPs via a smart contract.
