Introduction A couple of months ago, our research revealed a highly sophisticated infection chain and a complex .NET assembly-loading framework built on XAML markup, which strongly indicates a supply-chain attack targeting a custom Windows build used exclusively by government entities in Asia. The malicious framework has been labeled NetamLoader; at present, no attribution to any known APT group has been established. The sample came to light in the first half of 2026, when Kaspersky Security…

According to this year’s Microsoft Digital Defense Report, government agencies and services were the sector most impacted by cyber threats in 2026, accounting for 27% of observed activity, up from 17% in 2025. Governments are also the most frequently targeted sectors for nation-state activity. They are attractive targets because they hold sensitive information, operate essential services, and sit at the center of networks of agencies, contractors, technology providers, and critical…
Cisco Talos uncovered a cluster of activity we track as UAT-11587 targeting government and policy organizations across Asia, including in Taiwan, India, the Philippines, and Cambodia, to deliver a previously undocumented backdoor referred to as “Antino” in developer artifacts.
