PoC Malware Exploits Cloud Anti-Virus for Data Exfiltration [securityweek]

Presented at BlackHat USA 2017 by Itzik Kotler and Amit Klein from SafeBreach Labs, the PoC tool relies on packing data inside an executable the main malware process creates on the compromised endpoint. Thus, if the AV product employs an Internet-connected sandbox as part of its cloud service, data is exfiltrated as soon as the AV agent uploads the newly created executable to the cloud for further inspection, although the file is executed in an Internet connected sandbox.
