A campaign of 148 npm packages disguised as student web proxies turned visitors' browsers into a distributed denial-of-service botnet for roughly two weeks in May, according to new research from JFrog

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 […]

A new two-stage malware family called RustDuck is hijacking home routers, IP cameras, Android boxes, and poorly secured servers, then stitching them into a network built to knock websites and online services offline

Cybersecurity researchers have flagged half a dozen vulnerabilities in protobuf.js, a JavaScript and TypeScript implementation of Protocol Buffers (Protobuf), that, if successfully exploited, could result in remote code execution (RCE) and denial-of-service (DoS) attacks

Cybersecurity researchers have discovered a remote denial-of-service exploit that affects major web servers, including NGINX, Apache HTTPD, Microsoft IIS, Envoy, and Cloudflare Pingora

Cybersecurity researchers have discovered four new npm packages containing information-stealing malware, one of which is a clone of the Shai-Hulud worm open-sourced by TeamPCP

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

Cybersecurity researchers have warned of a surge in retaliatory hacktivist activity following the U.S.-Israel coordinated military campaign against Iran, codenamed Epic Fury and Roaring Lion

'Expect elevated activity for the foreseeable future' Iranian hackers have launched spying expeditions, digital probes, and distributed denial of service (DDoS) attacks in the wake of the US and Israel launching missile strikes over the weekend, and security researchers urge organizations to expect more cyber intrusions as the war continues.…

Security news rarely moves in a straight line. This week, it feels more like a series of sharp turns, some happening quietly in the background, others playing out in public view. The details are different, but the pressure points are familiar

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.

The Black Lotus Labs team at Lumen Technologies said it null-routed traffic to more than 550 command-and-control (C2) nodes associated with the AISURU/Kimwolf botnet since early October 2025

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

Cybersecurity researchers have disclosed details of a new botnet that customers can rent access to conduct distributed denial-of-service (DDoS) attacks against targets of interest

Researchers had to notify over 100 vendors of flaw that builds on 2023's Rapid Reset with neat twist past usual mitigations Security researchers Gal Bar Nahum, Anat Bremler-Barr, and Yaniv Harel have published details of a "common design flaw" in implementations of the HyperText Transfer Protocol 2 (HTTP/2) allowing those with ill intent to create "massive Denial of Service attacks".…

A novel attack technique could be weaponized to rope thousands of public domain controllers (DCs) around the world to create a malicious botnet and use it to conduct power distributed denial-of-service (DDoS) attacks

Cybersecurity researchers are calling attention to a malware campaign that's targeting security flaws in TBK digital video recorders (DVRs) and Four-Faith routers to rope the devices into a new botnet called RondoDox

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