Organisations urged to patch Microsoft Azure

Microsoft has urged Azure users to update their systems following the discovery of a new attack campaign targeting Linux Exim email servers.

Microsoft has confirmed that the attack affects servers running Exim version 4.87 to 4.91.

Customers have been asked to observe Azure security best practices and to patch or restrict network access to VMs running the affected versions of Exim.

Security researchers at Cybereason have suggested that the vulnerability can be exploited to gain remote command execution on the target machine, search the Internet for other machines to infect, and initiate a crypto miner.
