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

Malware campaigns distributing the RondoDox botnet have expanded their targeting focus to exploit more than 50 vulnerabilities across over 30 vendors

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

In the past, the vulnerability was exploited to drop Mirai botnet malware. Today, it's being used once more for another botnet campaign with its own malware.

Unpatched TP-Link Archer routers have become the target of a new botnet campaign dubbed Ballista, according to new findings from the Cato CTRL team

Threat actors are exploiting an unspecified zero-day vulnerability in Cambium Networks cnPilot routers to deploy a variant of the AISURU botnet called AIRASHI to carry out distributed denial-of-service (DDoS) attacks

Cybersecurity researchers have warned of a new large-scale campaign that exploits security flaws in AVTECH IP cameras and Huawei HG532 routers to rope the devices into a Mirai botnet variant dubbed Murdoc_Botnet

A newly identified Mirai botnet exploits over 20 vulnerabilities, including zero-days, in industrial routers and smart home devices

A Mirai botnet variant has been found exploiting a newly disclosed security flaw impacting Four-Faith industrial routers since early November 2024 with the goal of conducting distributed denial-of-service (DDoS) attacks

Mirari and Kaiten Botnet Variants Exploit Unpatched RoutersAttackers exploiting nearly decade-old D-Link router vulnerabilities drove a sharp rise in botnet activity in 2024 through variants of the Mirari and Kaiten taking advantage of unpatched devices. Operators of botnets known as Ficora and Capsaicin exploit nearly decade-old flaws.

A new Mirai-based malware campaign is actively exploiting unpatched vulnerabilities in Internet of Things (IoT) devices, including DigiEver DS-2105 Pro DVRs. [...]

Attackers Exploit Old Flaw, Hijack TP-Link Archer RoutersHalf a dozen different botnets are prowling the internet for TP-Link-brand Wi-Fi routers unpatched since last summer with the goal of commandeering them into joining distributed denial-of-service attacks. Chinese router manufacture TP-Link in June patched a command injection vulnerability.

A new Mirai-based malware botnet named 'InfectedSlurs' has been exploiting two zero-day remote code execution (RCE) vulnerabilities to infect routers and video recorder (NVR) devices. [...]
