If you’re a platform engineer or SRE, you know that managing infrastructure and efficiently managing it are two very different things. You’ve been able to run virtual machines (VMs) alongside containers in Red Hat Advanced Cluster Management for a while now. But as your fleet grows, finding that one specific VM acting up in a haystack of clusters can feel like a scavenger hunt you didn't sign up for.Red Hat Advanced Cluster Management for Kubernetes 2.15 redefines your daily workflow instead of just adding features. We’ve taken the capabilities you rely on and made them easier to use so

Researchers have discovered VoidLink, a sophisticated new Linux malware framework designed to infiltrate AWS, Google Cloud, and Azure. Learn how this Chinese-affiliated toolkit uses adaptive stealth to stay hidden.

Researchers discovered a modular, "cloud-first" framework that is feature-rich and designed to maintain stealthy, long-term access to Linux environments.

Microsoft on Tuesday rolled out its first security update for 2026, addressing 114 security flaws, including one vulnerability that it said has been actively exploited in the wild. Of the 114 flaws, eight are rated Critical, and 106 are rated Important in severity. As many as 58 vulnerabilities have been classified as privilege escalation, followed by 22 information disclosure, 21 remote code

### Summary The user-provided string `depName` in the `hermit` manager is appended to the `./hermit install` and `./hermit uninstall` commands without proper sanitization. ### Details Adversaries can provide a maliciously named hermit dependency in conjunctions with a tweaked Renovate configuration file to trick Renovate to execute arbitrary code. All values added to the `packagesToInstall` and `packagesToUninstall` variables in [lib/modules/manager/hermit/artifacts.ts](https://github.com/renovatebot/renovate/blob/41e8b99f86a6e2a56f80f7aa1a08a59d76f2358c/lib/modules/manager/hermit/artifacts.ts) are not being escaped using the `quote` function from the `shlex` package. This lack of proper sanitization for installing packages has been present in the product since the introduction of the hermit manager in version 32.135.0 (https://github.com/renovatebot/renovate/commit/b696abb3c2741508fbb4029f39153140a3722e1e), released on July 30 of 2022. In version 37.199.1 (https://github.com/renovate...

## Vulnerability Summary **Title:** Time-of-Check-Time-of-Use (TOCTOU) Symlink Vulnerability in SoftFileLock **Affected Component:** `filelock` package - `SoftFileLock` class **File:** `src/filelock/_soft.py` lines 17-27 **CWE:** CWE-362, CWE-367, CWE-59 --- ## Description A TOCTOU race condition vulnerability exists in the `SoftFileLock` implementation of the filelock package. An attacker with local filesystem access and permission to create symlinks can exploit a race condition between the permission validation and file creation to cause lock operations to fail or behave unexpectedly. The vulnerability occurs in the `_acquire()` method between `raise_on_not_writable_file()` (permission check) and `os.open()` (file creation). During this race window, an attacker can create a symlink at the lock file path, potentially causing the lock to operate on an unintended target file or leading to denial of service. ### Attack Scenario ``` 1. Lock attempts to acquire on /tmp/app.lock 2. ...

Cybersecurity researchers have disclosed details of a previously undocumented and feature-rich malware framework codenamed VoidLink that's specifically designed for long-term, stealthy access to Linux-based cloud environments According to a new report from Check Point Research, the cloud-native Linux malware framework comprises an array of custom loaders, implants, rootkits, and modular

Researchers detailed a souped-up version of the GoBruteforcer botnet that preys on servers with weak credentials and AI-generated configurations.

Secure container images are now essential for modern apps. These five options help teams reduce risk, cut patching effort, and improve long-term security.

This week made one thing clear: small oversights can spiral fast. Tools meant to save time and reduce friction turned into easy entry points once basic safeguards were ignored. Attackers didn’t need novel tricks. They used what was already exposed and moved in without resistance. Scale amplified the damage. A single weak configuration rippled out to millions. A repeatable flaw worked again and
