- UAC-0099’s ASHVEIN RAT hides commands in HTML to target Ukrainian officials. It’s a .NET infostealer, not magic. Stop kidding yourself if you think government servers are immune to basic phishing. This isn’t war; it’s bad OPSEC with a Russian accent. We're threadbare when we let simple trojans slip through the cracks. Check the seals on your digital cargo before it gets hijacked. For serious readers: audit your .NET environments and strip unnecessary HTML parsing permissions. Don't be the meat wallet that leaks state secrets because you clicked a pretty link.
