Botnet / DDoS Attack
Cybersecurity experts are alerting to a rise in malicious activity that leverages outdated D-Link routers, involving two distinct botnets: a Mirai variant known as FICORA and a Kaiten variant referred to as CAPSAICIN. “These botnets are often propagated through well-documented vulnerabilities in D-Link devices, enabling remote attackers to execute harmful commands via GetDeviceSettings on the HNAP (Home Network Administration Protocol) interface,” noted Vincent Li, a researcher at Fortinet FortiGuard Labs, in a Thursday analysis. “This HNAP flaw was first revealed nearly ten years ago, affecting multiple devices across various CVE identifiers, including CVE-2015-2051, CVE-2019-10891, CVE-2022-37056, and CVE-2024-33112.” According to telemetry data from the cybersecurity firm, attacks linked to FICORA have been globally dispersed, while those involving CAPSAICIN have predominantly targeted East Asian countries like Japan and Taiwan.
