Botnet Operators Execute First Known Exploit of Nearly Decade-Old FlawOperators behind a botnet picked up on a nearly decade-old flaw in Asus routers allowing an unauthenticated attacker to achieve remote code execution as a root user. VulnCheck began observing exploitation of the Asus vulnerability on May 17.

A new Mirai-based malware campaign is actively exploiting CVE-2025-29635, a high-severity command-injection vulnerability affecting D-Link DIR-823X routers, to enlist devices into the botnet. [...]

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

Thursday. Another week, another batch of things that probably should've been caught sooner but weren't

An active campaign has been observed targeting internet-exposed instances running ComfyUI, a popular stable diffusion platform, to enlist them into a cryptocurrency mining and proxy botnet

In early January 2026, KrebsOnSecurity revealed how a security researcher disclosed a vulnerability that was used to assemble Kimwolf, the world's largest and most disruptive botnet. Since then, the person in control of Kimwolf -- who goes by the handle "Dort" -- has coordinated a barrage of distributed denial-of-service (DDoS), doxing and email flooding attacks against the researcher and this author, and more recently caused a SWAT team to be sent to the researcher's home. This post examines what is knowable about Dort based on public information.

Check Point Research has reported a surge in attacks on a vulnerability in HPE OneView, driven by the Linux-based RondoDox botnet

The Kimwolf botnet, an Android variant of the Aisuru malware, has grown to more than two million hosts, most of them infected by exploiting vulnerabilities in residential proxy networks to target devices on internal networks. [...]

The Campaign Compromises Open-Source Vulnerability to Hack IoT Devices at ScaleSecurity firm CloudSEK has uncovered a botnet campaign that is exploiting the React2Shell vulnerability in the Meta-developed, open-source React framework across a variety of devices since December. The security firm attributed the campaign to RondoDox.

The story you are reading is a series of scoops nestled inside a far more urgent Internet-wide security advisory. The vulnerability at issue has been exploited for months already, and it's time for a broader awareness of the threat. The short version is that everything you thought you knew about the security of the internal network behind your Internet router probably is now dangerously out of date.

The RondoDox botnet has been observed exploiting the critical React2Shell flaw (CVE-2025-55182) to infect vulnerable Next.js servers with malware and cryptominers. [...]

A critical security flaw in the Sneeit Framework plugin for WordPress is being actively exploited in the wild, per data from Wordfence
