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.

Also: How AI May Democratize Cybercrime and How Everyday Routers Enable EspionageIn this week's ISMG panel, four ISMG editors discussed big shifts in cybersecurity: Anthropic's "dangerous" new AI model that can uncover thousands of zero-days, growing concerns about a surge in AI-driven flaws, and the FBI disrupting a Russian espionage campaign targeting everyday routers.

Juniper Tells Customers to Tune Their FirewallA critical vulnerability in Juniper Networks' primary operating system could give threat actors root level privileges to execute code on Juniper’s PTX Series routers. Successful exploitation would give attackers full command and control over devices without the need for authentication.

Black Duck Researchers Discover Flaw in Widely Used Broadcom ChipsetA flaw in Broadcom chipsets commonly used in wireless routers allows attackers to repeatedly knock offline the 5 gigahertz band, no matter how strong the security settings, say researchers.

Murdoc Botnet Uses Over 100 Distinct C2 Servers to Manage Infected DevicesA new variant of the Mirai malware is exploiting vulnerabilities in cameras and routers to infiltrate devices, download payloads and integrate them into an expanding botnet. Qualys tracked over 1,300 active internet protocol addresses linked to the Murdoc Botnet since its emergence in July 2024.

Flaws Enable Privilege Escalation and Remote ExploitationTaiwanese industrial computing firm Moxa Technologies is warning customers about two high-severity vulnerabilities affecting its routers and network appliances, posing significant security risks to operational technology environments.

Attackers Exploiting OS Command Injection VulnerabilityHackers are exploiting a high-severity command injection vulnerability in Chinese-manufactured Four-Faith industrial routers. Typical customers of Four-Faith use the routers for remote monitoring, control systems, supervisory control and data acquisition networks.

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.

Exploits Could Allow Remote Command Execution and AccessThe Taiwanese NAS maker QNAP Systems on Saturday patched multiple flaws in its operating system and applications that could allow attackers to compromise network storage devices. The patch also included multiple flaws in QNAP's router operating system QuRouter OS.

Vulnerabilities Could Lead to Unauthorized Data Access and ManipulationHalf a dozen vulnerabilities in a moderately priced Netgear router could allow attackers to bypass authentication, putting home users and small businesses at risk. The flaws could cause unauthorized access, network manipulation and exposure of sensitive data.

Unsanitized Inputs Leads to Remote Code ExecutionA gaming Wi-Fi router contained a zero-day that allowed a remote unauthenticated attacker to execute arbitrary code - a flaw that a static analysis cybersecurity firm attributed to insecure coding practices. Routers are a perennial source of risk to enterprises and home users alike.

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.
