According to this link (https://blog.appriver.com/threat-alert-microsoft-azure-malware), attacks have escalated to malware being hosted on the Azure service. Not only is Azure hosting malware, it is also functioning as the command and control infrastructure for the malicious files.
Roy Rashti, Cybersecurity Expert at BitDam:
“Cloud providers own their servers, meaning they have full access to the data. However, they’re in a tough spot because nobody wants them to scan the traffic or files they pay to host, but doing so is probably the most effective way to protect against malware.
Many attackers can be very quickly blocked by companies blacklisting their servers. However, when operating under a cloud service domain such as Amazon, Google, Microsoft or any other, the domain is hosted by those companies and should not be blacklisted.
Mitigating the threat along with its various forms and variants is a fight harder to win.”
