Zbtlink routers are shipped with a factory-implanted backdoor named ENDLESSDOORS, which establishes unauthenticated root shells by connecting to command-and-control servers. The backdoor, based on the 'rctl' tool, runs as a disguised kernel thread with root privileges and contacts C2 infrastructure every 35 seconds. It allows remote attackers to execute arbitrary commands or spawn interactive root shells without authentication, enabling full device takeover. The backdoor is present in at least 20 router models, all of which initiate connections to a shared set of C2 endpoints.

Attackers exploited a SQL injection vulnerability in a public-facing web application to gain access to an Oracle database, then leveraged Oracle's embedded Java Virtual Machine to compile and execute malicious Java code within the database itself. This post-exploitation toolkit, tracked as khunt by Huntress, allowed the attackers to achieve SYSTEM-level privilege escalation on the underlying Windows server without writing files to disk. The toolkit consists of multiple Java classes and PL/SQL wrappers that enable command execution, credential theft, file system access, and registry hive extraction. The malicious activity was traced to a single IP address, and detection requires hunting for specific object names and SQL patterns due to the in-memory nature of the attack.

Two trojanized npm packages, 'bianira-ui' and 'fluid-type-ui', have been identified as part of a malicious campaign leveraging a novel blockchain-based command-and-control (C2) technique dubbed NullReceiver. This method, attributed to North Korean threat actors, encodes the C2 server IP address within the recipient address of zero-value Ethereum transactions, eliminating the need for smart contracts or calldata payloads. The malware decodes the IP address from the first four bytes of the transaction's destination address and connects to it, with the decoded IP being 166.88.134[.]62. The technique improves stealth and resilience by using throwaway addresses and minimizing on-chain footprint.

A memory corruption vulnerability in the Linux kernel's Open vSwitch (OVS) datapath, tracked as CVE-2026-64531 and dubbed OVSwrap, allows local users to escalate privileges to root. The flaw stems from a 16-bit length field wraparound when processing Netlink attributes in OVS flow installation, which can be triggered without requiring existing OVS bridges or daemons. A public proof-of-concept exploit achieves reliable local privilege escalation by chaining kernel pointer leaks, arbitrary reads, and targeted decrements to modify credentials and gain root access. The exploit supports around 800 kernel builds and leaves behind modified sudoers files and persistent root shells. Default installations of numerous Linux distributions are vulnerable if Open vSwitch is enabled and unprivileged user namespaces are allowed.

Attackers exploited an authentication bypass vulnerability (CVE-2026-18577) in N-able's N-central remote monitoring and management platform to gain remote administrative access to customer servers. The initial fix for CVE-2026-18556 was incomplete, allowing attackers to exploit an alternate path, later tracked as CVE-2026-18577, affecting N-central builds prior to 2026.3.1.7. After compromising N-central servers, attackers used Take Control for lateral movement and deployed Cloudflare tunnels as persistent services on managed endpoints, enabling remote access without inbound firewall rules. N-able identified six malicious IP addresses used in the attacks, and Huntress observed exploitation at one partner account, leading to access across nine downstream organizations. Post-compromise activity included process enumeration, but no data exfiltration was confirmed. Customers are advised to upgrade to build 2026.3.1.7 and hunt for malicious indicators such as suspicious svchost.exe instances and Cloudflared services.
