BROWSER-PLUGINS -- Snort has detected suspicious browser plugin traffic, likely targeting the ActiveX plugin in Internet Explorer, though this could apply to any browser. Attackers have refined techniques to smuggle extensions into the Chrome Web Store, which they can then modify remotely once downloaded to add or activate malicious or spyware features. This can be similar to a Potentially Unwanted Application, as valuable data and network access is often allowed on a phone or browser without proper investigation. Some extensions also mimic more well-known and trusted ones (AdBlock, etc.)
