A newly discovered Windows loader, OXLOADER, is being distributed via malicious Google Ads impersonating Node.js to deliver the CASTLESTEALER infostealer. The loader utilizes advanced evasion techniques, including control-flow flattening, anti-sandbox checks, and staging shellcode within the .reloc section of a copied system DLL, to maintain low detection rates across static engines.
A malvertising campaign is leveraging a fake Claude AI website to distribute a malicious MSI installer. The infection chain employs DLL sideloading via a legitimate G DATA executable to execute DonutLoader, which ultimately deploys a novel backdoor dubbed 'Beagle' for remote command execution and file manipulation.
Cybercriminals are increasingly abusing the Keitaro adtech platform to optimize the distribution of malware, phishing, and scams. By leveraging Keitaro's built-in tracking, cloaking, and traffic distribution capabilities, actors can efficiently target victims, evade detection, and scale operations across multiple threat types including wallet drainers and infostealers.
