Essential reading for developers and security professionals alike: a comprehensive comparison of vulnerability databases to help you cut through the noise.

Upgrade your PostgreSQL instance to the newest version with confidence! In this benchmarking blog post, we show you the performance improvements you can expect when upgrading from PostgreSQL 13 to 16.

We're gearing up with some seriously cool stuff for Black Hat! But first, a little sneak peek - not just one, but TWO of Wallarm's open-source tools will be featured in the Arsenal showcase at Black Hat USA this year. Black Hat Arsenal unites researchers and the open-source community to display their newest open-source tools and products, allowing presenters to engage directly with attendees. Its schedule is now live, so save the date to watch presentations of API Firewall and GoTestWAF.

In our interconnected online world, the security of applications and the data they process is essential. Open-Source Intelligence (OSINT) plays a critical role in enhancing application security by offering valuable insights into potential threats, vulnerabilities, and the overall security posture of an organization.

The Sysdig Threat Research Team (TRT) continued observation of the SSH-Snake threat actor we first identified in February 2024. New discoveries showed that the threat actor behind the initial attack expanded its operations greatly, justifying an identifier to further track and report on the actor and campaigns: CRYSTALRAY. This actor previously leveraged the SSH-Snake open source software (OSS) penetration testing tool during a campaign exploiting Confluence vulnerabilities.

Jay Jacobs and I recently delivered an RSA presentation called Quantifying the Probability of Flaws in Open Source. Since many people didn’t get a chance to see it, I thought I’d summarize some of the findings here for posterity. The question we investigated was simple, at least conceptually: what are the red flags of an open-source repository? Are there characteristics of a given open source library that would reliably indicate it was safer than others?

On July 1, 2024, OpenSSH released fixes for CVE-2024-6387, a vulnerability in OpenSSH’s server (sshd) on glibc-based Linux systems allowing for potential Remote Code Execution (RCE). OpenSSH is a widely-used suite of secure networking tools based on the SSH protocol, providing encryption for secure communication and file transfers, and is essential for remote management on Unix systems. CVE-2024-6387 is a signal handler race condition that allows unauthenticated Remote Code Execution (RCE) as root.
