[CRITICAL] Mirai DDoS malware variant expands targets with 13 router exploits
## Mirai DDoS malware variant expands targets with 13 router exploits
## Bill Toulas
A Mirai-based DDoS (distributed denial of service) malware botnet tracked as IZ1H9 has added thirteen new payloads to target Linux-based routers and routers from D-Link, Zyxel, TP-Link, TOTOLINK, and others.
Fortinet researchers report observing a peak in the exploitation rates around the first week of September, reaching tens of thousands of exploitation attempts against vulnerable devices.
IZ1H9 compromises devices to enlist them to its DDoS swarm and then launches DDoS attacks on specified targets, presumably on the order of clients renting its firepower.
## Extensive IoT targeting
The more devices and vulnerabilities targeted by a DDoS malware increased the potential to build a large and powerful

IZ1H9 Campaign Enhances Its Arsenal with Scores of Exploits
By Cara Lin | October 09, 2023
Affected Platforms: Linux
Impacted Users: Any organization
Impact: Remote attackers gain control of the vulnerable systems
Severity Level: Critical
In September 2023, our FortiGuard Labs team observed that the IZ1H9 Mirai-based DDoS campaign has aggressively updated its arsenal of exploits. Thirteen payloads were included in this variant, including D-Link devices, Netis wireless router, Sunhillo SureLine, Geutebruck IP camera, Yealink Device Management, Zyxel devices, TP-Link Archer, Korenix Jetwave, and TOTOLINK routers.
Based on the trigger counts recorded by our IPS signatures, it is evident that peak exploitation occurred on September 6, with trigger counts ran
