RustDuck is a small, evolving DDoS botnet migrating to Rust. It uses advanced encryption, anti-analysis evasion, and exploits known IoT flaws. Since February 2026, researchers at QiAnXin’s XLab have been tracking a new malware family, called RustDuck, that hijacks routers, cameras, Android set-top boxes, and exposed servers, then uses them to flood targets with junk […]

C0XMO is a new Gafgyt botnet variant exploiting old router flaws, spreading across IoT devices, killing rivals, and enabling large-scale DDoS attacks. In March 2026, FortiGuard Labs discovered a new variant of the Gafgyt botnet, dubbed C0XMO, which is noticeably more capable than its predecessors. The malware spreads through CVE-2021-27137, a stack buffer overflow in […]

DOJ Says KimWolf Powered Massive DDoS-for-Hire OperationsU.S. prosecutors charged a Canadian man accused of operating the KimWolf botnet, alleging the DDoS-for-hire platform compromised nearly two million IoT devices and powered attacks that reached record traffic volumes worldwide.

Cybersecurity researchers have exposed a new Mirai-derived botnet that self-identifies as xlabs_v1 and targets internet-exposed devices running Android Debug Bridge (ADB) to enlist them in a network capable of carrying out distributed denial-of-service (DDoS) attacks

Cybersecurity researchers have lifted the curtain on a stealthy botnet that's designed for distributed denial-of-service (DDoS) attacks

Millions of hijacked devices powered traffic floods targeting defense systems and beyond The US government has moved to disrupt a cluster of IoT botnets behind some of the largest DDoS attacks ever recorded, including traffic bursts topping 30 terabits per second.…

Authorities from the United States, Germany, and Canada have taken down Command and Control (C2) infrastructure used by the Aisuru, KimWolf, JackSkid, and Mossad botnets to infect Internet of Things (IoT) devices. [...]

The U.S. Department of Justice (DoJ) on Thursday announced the disruption of command-and-control (C2) infrastructure used by several Internet of Things (IoT) botnets like AISURU, Kimwolf, JackSkid, and Mossad as part of a court-authorized law enforcement operation

The U.S. Justice Department joined authorities in Canada and Germany in dismantling the online infrastructure behind four highly disruptive botnets that compromised more than three million hacked Internet of Things (IoT) devices, such as routers and web cameras. The feds say the four botnets -- named Aisuru, Kimwolf, JackSkid and Mossad -- are responsible for a series of recent record-smashing distributed denial-of-service (DDoS) attacks capable of knocking nearly any target offline.

A new Internet-of-Things botnet called Kimwolf has spread to more than 2 million devices, forcing infected systems to participate in massive distributed denial-of-service (DDoS) attacks and to relay other malicious and abusive Internet traffic. Kimwolf's ability to scan the local networks of compromised systems for other IoT devices to infect makes it a sobering threat to organizations, and new research reveals Kimwolf is surprisingly prevalent in government and corporate networks.

PLUS: New kind of DDOS from the Americas; Predator still hunting spyware targets; NIST issues IoT advice; And more! Infosec in Brief The Apache Foundation last week warned of a 10.0-rated flaw in its Tika toolkit.…

Aisuru, the botnet responsible for a series of record-smashing distributed denial-of-service (DDoS) attacks this year, recently was overhauled to support a more low-key, lucrative and sustainable business: Renting hundreds of thousands of infected Internet of Things (IoT) devices to proxy services that help cybercriminals anonymize their traffic. Experts says a glut of proxies from Aisuru and other sources is fueling large-scale data harvesting efforts tied to various artificial intelligence (AI) projects, helping content scrapers evade detection by routing their traffic through residential connections that appear to be regular Internet users.

The world's largest and most disruptive botnet is now drawing a majority of its firepower from compromised Internet-of-Things (IoT) devices hosted on U.S. Internet providers like AT&T, Comcast and Verizon, new evidence suggests. Experts say the heavy concentration of infected devices at U.S. providers is complicating efforts to limit collateral damage from the botnet's attacks, which shattered previous records this week with a brief traffic flood that clocked in at nearly 30 trillion bits of data per second.

FastNetMon says 1.5 Gpps deluge from hijacked routers, IoT kit nearly drowned scrubbing shop A DDoS mitigation provider was given a taste of the poison it tries to prevent, after being smacked by one of the largest packet-rate attacks ever recorded – a 1.5 billion packets per second (1.5 Gpps) flood that briefly threatened to knock it off the internet.…

KrebsOnSecurity last week was hit by a near record distributed denial-of-service (DDoS) attack that clocked in at more than 6.3 terabits of data per second (a terabit is one trillion bits of data). The brief attack appears to have been a test run for a massive new Internet of Things (IoT) botnet capable of launching crippling digital assaults that few web destinations can withstand. Read on for more about the botnet, the attack, and the apparent creator of this global menace.

Threat actors have been observed actively exploiting security flaws in GeoVision end-of-life (EoL) Internet of Things (IoT) devices to corral them into a Mirai botnet for conducting distributed denial-of-service (DDoS) attacks

Cybersecurity researchers are warning of continued risks posed by a distributed denial-of-service (DDoS) malware known as XorDDoS, with 71.3 percent of the attacks between November 2023 and February 2025 targeting the United States

A new botnet malware named 'Eleven11bot' has infected over 86,000 IoT devices, primarily security cameras and network video recorders (NVRs), to conduct DDoS attacks. [...]

Web infrastructure and security company Cloudflare on Tuesday said it detected and blocked a 5.6 Terabit per second (Tbps) distributed denial-of-service (DDoS) attack, the largest ever attack to be reported to date

Two separate campaigns are targeting flaws in various IoT devices globally, with the goal of compromising them and propagating malware worldwide.
