This analysis examines how threat actors abuse Keitaro, an advertising performance tracker, for various malicious purposes. The report covers a wide range of threats, including malware delivery, phishing, scams, and illegal content distribution. Key findings include the use of Keitaro for cloaking and traffic distribution in malvertising campaigns, spam operations leveraging Keitaro for cryptocurrency wallet draining, and the abuse of Keitaro in investment scams. The report also highlights specific threat actors and their tactics, such as domain hijacking for adult content delivery and the use of fake arrests as clickbait for investment scams. Overall, the analysis demonstrates how Keitaro's features make it attractive to cybercriminals seeking to maximize their reach with minimal effort.
EtherRAT, a Node.js-based backdoor linked to a North Korean APT group, was detected in a retail customer's environment. It allows arbitrary command execution, extensive system information gathering, and asset theft. The malware uses 'EtherHiding' to store C2 addresses in Ethereum smart contracts, making infrastructure resilient to takedowns. It communicates using CDN-like beaconing to blend with normal traffic. Initial access varied, including ClickFix and IT Support scams via Microsoft Teams. A SYS_INFO module performs comprehensive host fingerprinting for target selection. The malware checks for CIS languages and self-destructs if found. It collects detailed system information, including hardware, software, and network details.
This is the first update to the TeamPCP supply chain campaign threat intelligence report, "When the Security Scanner Became the Weapon" (v3.0, March 25, 2026). That report covers the full campaign from the February 28 initial access through the March 24 LiteLLM PyPI compromise. This update covers developments since publication.

Elastic Security Labs analyzes VoidLink, a sophisticated Linux malware framework combining Loadable Kernel Modules (LKMs) and eBPF for persistence. The rootkit, developed by a Chinese-speaking threat actor, evolved through four generations, targeting kernels from CentOS 7 to Ubuntu 22.04. VoidLink employs advanced techniques like delayed initialization, runtime key rotation, and a hybrid LKM-eBPF architecture for comprehensive stealth. Notable features include an ICMP-based covert channel, process protection, and memfd-aware boot loading. Evidence suggests AI-assisted development, lowering the barrier for kernel-level rootkit creation. Detection strategies and defensive recommendations are provided to counter this emerging threat.

Spammers are disguising fraudulent links within legitimate survey platforms — emails containing these links easily bypass standard spam filters. We analyze the scheme, highlight the red flags, and provide defensive strategies.
Insikt Group identified five distinct clusters using the ClickFix social engineering technique for initial access. These clusters impersonate various services like Intuit QuickBooks and Booking.com, demonstrating operational variance but similar core techniques. ClickFix manipulates victims into executing malicious commands within native system tools, bypassing traditional security controls. The methodology has become a standardized template for cybercriminals and APT groups. Campaigns target diverse sectors and use sophisticated obfuscation and living-off-the-land tactics. Defenders are advised to implement aggressive behavioral hardening and user awareness training to mitigate these threats.

TeamPCP has launched a supply chain attack targeting LiteLLM, an open-source Python library used in 36% of cloud environments. Malicious versions 1.82.7 and 1.82.8 were published on PyPI, employing sophisticated techniques for payload delivery and persistence. The compromised packages exploit Python's .pth mechanism for stealthy execution across any Python process. The malware collects sensitive data including API keys, cloud credentials, and CI/CD secrets, encrypting and exfiltrating them to attacker-controlled domains. This attack follows TeamPCP's previous compromises of Aqua Security's Trivy and Checkmarx tools, highlighting an ongoing campaign against the open-source ecosystem. The incident underscores the potential for widespread impact and the need for vigilance in software supply chain security.
