Vulns in Azure Linux VMs being actively exploited
Security researchers from Wiz.io found vulnerabilities in Microsoft Open Management Infrastructure (OMI)project that can trivially be exploited and used to remotely execute code on Linux virtual machines running in Microsoft’s Azure cloud.
By not providing an authentication token, the OMI agent on the VM would simply not perform an authentication check and default to running the commands as root. Oops.
The OMI agent is installed when selecting other Azure monitoring and log management services. Some users may not realise it has been installed when selecting those options: those with port 5986, 5985, or 1270 externally exposed are vulnerable.
The four vulnerabilities involved range from CVSS scores of 7.0 to 9.8/10 and user’s need to manually update the OMI agent (version 220.127.116.11 onwards is not vulnerable).
It hasn’t taken cybercriminals long to pick up on the issue and, from Thursday this week, they have used a public proof-of-concept to enlist computer and bandwidth into mining cryptocurrency and participating in DDoS attacks.
“Astonishingly” sloppy work from Microsoft and one to check and patch immediately!

OWASP Top 10 rankings updated
The Open Web Application Security Project (OWASP) has released a draft update to the ‘top 10’ vulnerabilities introduced by developers into software for the first time since 2017. Injection (such as SQL or XSS) falls from the top spot to third, while Broken Access Control is up five to take the crown.
The list is a good reference for software engineering and security teams to use as a benchmark for things that really shouldn’t be getting through to production environments.
Microsoft goes passwordless
Microsoft announced this week that users will soon be able to go ‘passwordless’ on their accounts, relying on security keys, multi-factor codes and an authenticator app to login instead of a string of letters, numbers and special characters.
In Redmond’s post, they highlighted that they believe there are 579 attacks using passwords event second, or 18 billion annually and that 15% of people use their pets’ names as inspiration for passwords.
For their ubiquity, passwords are one of the major things that ‘security has got wrong’ especially given the huge number of accounts and services that form part of our modern lives. So expect the trend to continue as other large players begin to phase them out in favour of other authentication mechanisms.

If accounting were like cyber security
There are lots we can learn from other, more established professions and this fun, sarcastic take highlights some of the bizarre things cyber does as a profession and the things we could learn from accounts.
