Zyxel fixes zero-day exploited to hack nearly 1,000 network switches
Zyxel has patched a zero-day vulnerability in its GS1900 series network switches that hackers exploited to compromise nearly 1,000 devices worldwide and steal configuration files and credentials. The vulnerability, tracked as CVE-2026-107441, is an out-of-bounds write flaw in the switches’ web management interface that allows an unauthenticated attacker with network access to execute operating system […]
D-Link warns of max severity zero-day bug in DIR-822A routers
D-Link warned customers of a maximum-severity vulnerability (CVE-2026-86296) with public proof-of-concept (PoC) exploit code and no patch, affecting legacy DIR-822A dual-band Wi-Fi routers. This security flaw stems from a stack-based buffer overflow and improper data handling in the DHCP server component and can be exploited without authentication or user interaction. Attackers without valid credentials on […]
Hackers exploit new MikroTik RouterOS flaws to hijack routers
Hackers are exploiting a chain of two recently disclosed vulnerabilities in MikroTik routers to take control of devices with SSH services exposed to the internet. One of the security issues, tracked as CVE-2026-67276, is an SSH authentication bypass flaw in MikroTik RouterOS caused by incomplete validation of RSA public keys. An attacker who knows a […]
Chinese Fire Ant hackers turn Cisco routers into spying platforms
The researchers discovered Fire Ant’s new tactic after finding an active GRE (Generic Routing Encapsulation) tunnel interface on a Cisco IOS XR router that could not be explained by a running configuration or commit history. According to incident response company Sygnia, the threat actor switched from targeting VMware hypervisors to compromising Cisco routers, TACACS authentication servers, […]
Unpatched Calix flaw lets hackers bypass NAT to expose internal devices
An unpatched vulnerability in Calix GS7 XGS (GS5239XG) residential routers used by multiple U.S. broadband providers allows remote, unauthenticated attackers to create port-forwarding rules that can expose local network devices to the public internet. The flaw is tracked as CVE-2026-75501 and is described as a missing authentication issue that affects devices running EXOS/6.6.47 firmware. Security […]
New Dysphoria DDoS botnet spreads to 200k devices worldwide
A botnet called Dysphoria has compromised around 200,000 devices across the world and is using them for distributed denial of service (DDoS) attacks and traffic relay operations. According to QiAnXin XLab cybersecurity researchers, Dysphoria evolved from the ‘jackskid’ and ‘fbot’ malware by adding a covert blockchain-based command-and-control (C2) resolution mechanism. Specifically, the botnet uses Ethereum […]
US and allies warn of Russian critical infrastructure attacks
Cybersecurity agencies from the United States and eight other countries have issued a joint warning that Russian state hackers are targeting vulnerable and poorly configured routers to infiltrate critical infrastructure networks. The joint advisory, co-authored by the NSA, FBI, and CISA, along with 15 other agencies from Australia, the United Kingdom, Canada, New Zealand, Estonia, Finland, France, […]
AryStinger botnet infected thousands of D-Link routers worldwide
A previously undocumented malware botnet named AryStinger has compromised more than 4,000 outdated routers to turn them into proxies for malicious traffic. Researchers at Qianxin’s XLab threat intelligence team say that the malware converts infected devices into remotely controlled “executors” that can perform scanning, proxying, tunneling, command execution, and other activities on behalf of the […]
Acer working to patch max severity zero-days in Wave 7 routers
Acer confirmed that it’s working to address two maximum-severity zero-day vulnerabilities affecting its Wave 7 mesh routers. According to a Friday security advisory, the two security flaws were reported by security researcher Gergo Pap and affect Wave 7 routers running firmware version T7c_GBL_1.01.000055 or earlier. The first zero-day, a broken access control vulnerability tracked as CVE-2026-49200, can […]
New Mirai campaign exploits RCE flaw in EoL D-Link routers
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. CVE-2025-29635 allows an attacker to execute arbitrary commands on remote devices by sending a POST request to a vulnerable endpoint, triggering remote command execution (RCE). Akamai’s SIRT, which detected the Mirai campaign in March […]
