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.

Threat actors are exploiting security flaws in TBK DVR and end‑of‑life (EoL) TP-Link Wi-Fi routers to deploy Mirai-botnet variants on compromised devices, according to findings from Fortinet FortiGuard Labs and Palo Alto Networks Unit 42

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.

Cybersecurity researchers have discovered five vulnerabilities in Fluent Bit, an open-source and lightweight telemetry agent, that could be chained to compromise and take over cloud infrastructures

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.

Threat actors are weaponizing exposed Java Debug Wire Protocol (JDWP) interfaces to obtain code execution capabilities and deploy cryptocurrency miners on compromised hosts

A vulnerability in the popular Python-based tool for building AI agents and workflows is under active exploitation, allowing for full system compromise, DDoS attacks, and potential loss or theft of sensitive data

Cybersecurity researchers have called attention to a new campaign that's actively exploiting a recently disclosed critical security flaw in Langflow to deliver the Flodrix botnet malware

This blog uncovers an active campaign exploiting CVE-2025-3248 in Langflow versions before 1.3.0 that deploys the Flodrix botnet, enabling threat actors to achieve full system compromise, initiate DDoS attacks, and potentially exfiltrate sensitive data.

The largest distributed denial-of-service (DDoS) attack to date peaked at 5.6 terabits per second and came from a Mirai-based botnet with 13,000 compromised devices. [...]

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

A malware botnet is exploiting a zero-day vulnerability in end-of-life GeoVision devices to compromise and recruit them for likely DDoS or cryptomining attacks. [...]

An attacker is using the tool to deploy a cryptominer and the Tsunami DDoS bot on compromised systems.

Don't Brush in Fear, as Supposed DDoS Dental Trauma Fails to Pass MusterBreathless reports claim 3 million IoT toothbrushes have been remotely compromised and used to target unsuspecting businesses via distributed denial-of-service attacks. Just one problem: This story has more holes in it than the teeth of kid with a 10-pack-a-day Gummy Bear habit.

In the latest Verizon "Data Breach Investigations Report," denial-of-service attacks are the most common type of security incident, but when it comes to breaches, nearly four-in-ten attackers compromise systems.

A new botnet called Dark Frost has been observed launching distributed denial-of-service (DDoS) attacks against the gaming industry

New samples of the RapperBot botnet malware have added cryptojacking capabilites to mine for cryptocurrency on compromised Intel x64 machines. [...]

Hyper-volumetric DDoS (distributed denial of service) attacks in the first quarter of 2023 have shifted from relying on compromised IoT devices to leveraging breached Virtual Private Servers (VPS). [...]

A new Golang-based botnet dubbed HinataBot has been observed to leverage known flaws to compromise routers and servers and use them to stage distributed denial-of-service (DDoS) attacks
