CAPE Sandbox exposes an HTTP endpoint (http://localhost:8000/browser_extension) used to log HTTP trafifc. You can detect CAPE by sending a dummy HTTP request to this endpoint and checking the response. You can then craft fake HTTP data and it’ll show up on VirusTotal.

For the hardcore reverse engineers and malware analysts out there, my ex-colleague just dropped a deep dive into 'Scatterbrain,' the obfuscator behind PoisonPlug malware. If you're into long technical breakdowns, this one's worth a read. cloud.google.com/blog/topics/th…
