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

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you thought you knew about the security of the internal network behind your Internet router probably is now dangerously out of date.

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

No formal attribution made but two separate probes hint at the same suspect Thousands of Asus routers are currently ensnared by a new botnet that is trying to disable Trend Micro security features before exploiting vulnerabilities for backdoor access.…

The FBI also issued a list of end-of-life routers you need to replace Earlier this week, the FBI urged folks to bin aging routers vulnerable to hijacking, citing ongoing attacks linked to TheMoon malware. In a related move, the US Department of Justice unsealed indictments against four foreign nationals accused of running a long-running proxy-for-hire network that exploited outdated routers to funnel criminal traffic.…

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.
