Understanding Kubernetes Identities, Part 1

When it comes to Kubernetes, managing identities is pivotal for ensuring secure and efficient cluster operations. These identities can be human users or machines, each requiring specific permissions to perform their tasks. In our latest research, we have explored what Kubernetes identities are, the default identities, the permissions they can have, how to configure these…

regreSSHion: RCE in OpenSSH’s Server on glibc-based Linux Systems (CVE-2024-6387)

OpenSSH is widely known for managing secure shell connections (SSH). However, a recently discovered vulnerability in OpenSSH's server (sshd), known as regreSSHion, has been identified. If a client does not authenticate within the LoginGraceTime (120 seconds by default, 600 seconds in older versions), sshd's SIGALRM handler is called asynchronously. This signal handler calls functions that…

Evaluating Microsoft’s Cyber Hack

Russian state-sponsored threat actor Nobelium recently attacked Microsoft and hacked numerous accounts using a password-spray attack. This allowed them to access a test account and gain access to Microsoft corporate email accounts, including senior leaders. After gaining access, they were able to operate within Microsoft’s infrastructure for more than two months before being discovered. This…
