File-based attacks are a growing concern in cybersecurity. These attacks involve tampering with files to gain unauthorized access, steal information, or cover up malicious activities. In this post, we’ll break down what file-based attacks are, look at some real-world examples, and walk through a typical attack scenario. What Are File-Based Attacks? File-based attacks exploit how […]

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 […]

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 […]
