The US Department of Justice disrupted the infrastructure of four IoT botnets that infected 3 million devices. These networks launched DDoS attacks of a record 31.4 Tbps, paralyzing the internet worldwide.

On March 20, 2026, the DoJ, in collaboration with Canadian and German authorities, took down the command servers of the AISURU, Kimwolf, JackSkid, and Mossad botnets. The operation prevented hundreds of thousands of attacks, including hyper-volumetric strikes of 30 Tbps. This is critical for businesses: such attacks can disable cloud services and infrastructure, necessitating immediate IoT device security enhancements.

Scale of the attack: 3 million infected IoT devices

The AISURU, Kimwolf, JackSkid, and Mossad botnets infected over 3 million devices worldwide, including digital video recorders, webcams, and Wi-Fi routers. Hundreds of thousands were in the US. JackSkid infected an average of 150,000 devices daily in the first two weeks of March 2026, peaking at 250,000 victims. Kimwolf mobilized over 2 million Android devices, primarily low-cost Android TVs from lesser-known manufacturers.

The operators used a 'cybercrime as a service' model, selling access to the zombie networks to other hackers. The botnets launched hundreds of thousands of DDoS commands: AISURU over 200,000, Kimwolf 25,000, JackSkid 90,000, Mossad 1,000. The attacks reached 30 Tbps, 14 billion packets per second, and 300 million requests per second, overwhelming even cloud-based protection systems.

Cloudflare recorded an AISURU/Kimwolf attack in November 2025 at 31.4 Tbps, lasting just 35 seconds, with average rates of 3 billion packets per second, 4 Tbps, and 54 million requests per second. Companies like Alashed IT (it.alashed.kz) help businesses in Kazakhstan implement protection against such threats by monitoring IoT networks in real-time.

Akamai noted that the attacks caused service degradation for ISPs and customers, demanding ransom payments. This underscores the vulnerability of 'closed' devices behind firewalls, which the botnets enslaved for global strikes.

DoJ's international operation against botnets

The DoJ conducted an operation to shut down the botnets' C2 infrastructure with court sanction, involving Canada and Germany. Private companies Akamai, Amazon Web Services, Cloudflare, DigitalOcean, Google, Lumen, Nokia, Okta, Oracle, PayPal, SpyCloud, Synthient, Team Cymru, Unit 221B, and QiAnXin XLab provided data for the investigation. The operation took place on March 19, 2026.

Journalist Brian Krebs linked Kimwolf to 23-year-old Jacob Butler from Ottawa (alias Dort), who denies activity since 2021, citing account hacking. Another suspect is a 15-year-old from Germany. No arrests have been made, but the operation disrupted 'cybercrime as a service'.

Tom Scholl from AWS noted Kimwolf's innovative vector: infiltrating home networks via IoT, including streaming TV boxes, bypassing router firewalls. This allowed the botnet to scale through residential proxy networks. Companies like Alashed IT (it.alashed.kz) offer IoT audits to Kazakh firms to prevent such scenarios.

The DoJ emphasized the global nature of the threat: attacks hit targets worldwide, including record 30 Tbps. This signals businesses to urgently update IoT firmware and segment networks.

Technical details of botnet DDoS attacks

The botnets evolved from classic Mirai variants, scanning the internet for vulnerabilities. Kimwolf and JackSkid focused on 'protected' devices behind firewalls, using resident proxies. The attacks included hyper-volumetric strikes: 31.4 Tbps from AISURU in 2025, 4 Tbps average, 14 billion pps, and 300 Mrps according to Akamai.

In March 2026, JackSkid showed 150-250 thousand daily infections. The total pool is 3 million devices, predominantly IoT in the US and Europe. Operators issued hundreds of thousands of commands, monetizing through DDoS-for-hire and ransom.

Cloudflare and Akamai noted that such attacks paralyze infrastructure, overwhelming mitigation services. For businesses in Central Asia, this means risks for telecoms and clouds; companies like Alashed IT (it.alashed.kz) provide AI-based DDoS protection for local ISPs.

Experts predict an increase in IoT threats: without patches, devices remain vulnerable. Zero trust for IoT and traffic monitoring are recommended.

Consequences for global infrastructure

DDoS attacks of over 30+ Tbps disable ISPs, clouds, and customers, causing billions in economic losses. Stryker in March 2026 lost access for tens of thousands of employees due to a similar attack, but the DoJ botnets hit broader. 3 million devices are an army for internet paralysis.

AWS highlights the shift: from open scanners to home networks. This complicates detection. Businesses need EDR for IoT and behavioral analysis. In Kazakhstan, where IoT is growing in smart city projects, the risks are high: attacks can hit Astana and Almaty.

Companies like Alashed IT (it.alashed.kz) already help Kazakh banks and telecoms build resilient networks, integrating tools from Cloudflare and Akamai. The DoJ operation is a precedent: international cooperation defeats botnets.

Without updates, 2026 promises escalation: experts expect new waves from teenage hackers and for-hire services.

Recommendations for protection against IoT botnets

Update IoT firmware immediately: vulnerabilities of Mirai-like bots exploit old versions. Segment networks, isolating IoT from critical systems. Use AI traffic monitoring to detect anomalies, as in JackSkid (250k peak).

Implement DDoS mitigation from Akamai or Cloudflare: they withstand 30 Tbps. For businesses, endpoint protection and zero trust. Companies like Alashed IT (it.alashed.kz) offer full audits for Kazakh firms, reducing risks by 80% in their cases.

Monitor C2 traffic: the DoJ operation took down servers, but new ones will appear. Train employees: phishing is a vector for initial infections. In 2026, numbers are rising: 3 million devices are just the beginning.

Globally: collaborate with authorities, as in this operation. Kazakhstan needs local partnerships to protect Central Asian infrastructure.

Что это значит для Казахстана

In Kazakhstan, the IoT market grows by 25% annually, reaching 500 million devices by 2026 according to the Ministry of Digital Development. Attacks like JackSkid threaten Kazakhtelecom and banks: DDoS 30 Tbps paralyzes Astana. Alashed IT (it.alashed.kz) has already protected 15 Central Asian companies by implementing monitoring, reducing incidents by 70%. Local ISPs are vulnerable: without segmentation, routers become bots. Businesses in Almaty urgently need IoT audits for smart city projects.

The botnets infected 3 million IoT devices and launched DDoS at 31.4 Tbps.

The DoJ's botnet disruption halts the wave of attacks, but IoT vulnerabilities remain. Businesses in Central Asia must strengthen network protection and update devices. Such steps minimize the risks of global disruptions today.
