This report analyzes ongoing malvertising campaigns that deliver fake ‘converter’ apps which install .NET-based remote access trojans; it identifies the typical infection chain (malicious ad → downloader → scheduled task → updater → C2), enumerates extensive IOCs (delivery domains, file hashes, and code-signing thumbprints), and provides practical detection and mitigation guidance including scheduled-task auditing, AppLocker/WDAC rules, and THOR scanning configurations.
