Security researchers have documented a resurgence of malicious Windows installer files that use embedded imagery as part of their attack delivery mechanism. The technique involves encoding malicious payloads within image data, likely using base64 encoding to evade detection systems. This represents an ongoing evolution in how threat actors package and distribute malware through seemingly legitimate installation files.

Why it matters in Western Canada: Organizations across Western Canada relying on Windows-based infrastructure and third-party software installations face increased risk from this technique. Educational institutions and government bodies managing large software deployments should be particularly vigilant about MSI file sources.
