For over 25 years, a technology utilized for vital data and voice radio communications globally has remained under wraps, preventing in-depth testing for potential vulnerabilities. However, a small group of researchers in the Netherlands has now shed light on it, uncovering significant flaws, including a deliberate backdoor.

A new flaw in AMD's Zen 2 processors is detailed in this blog post (archive.org snapshot) today, July 24, 2023. The 'Zenbleed' flaw affects the entire Zen 2 product stack, from AMD's EPYC data center processors to the Ryzen 3000 CPUs, and can be exploited to steal sensitive data stored in the CPU, including encryption keys and login credentials.

The ISO 27000 series is an industry standard that has long defined and dictated base-level requirements for organizations’ information security management systems (ISMS). Through more than a dozen standards, the framework helps organizations demonstrate management commitment to their ISMS as they regularly review and improve their systems and procedures.

ModSecurity is an open-source Web Application Firewall (WAF) engine maintained by Trustwave. This blog post discusses an issue with four transformation actions that could enable a Denial of Service (DoS) attack by a malicious actor. The issue has been addressed with fixes in v3.0.10. ModSecurity v2 is not affected.

Kroll has identified two different file exfiltration methodologies leveraged by threat actors, primarily CLOP, during recent engagements involving the exploitation of the MOVEit vulnerability (CVE-2023-34362) throughout May and June 2023. In the vast majority of Kroll’s global MOVEit investigations, the primary data exfiltration method consisted of utilizing the dropped web shell to inject a session or create a malicious account (named Method 1 for this piece).

On July 24, a group of researchers at Midnight Blue announced TETRA:BURST, a set of five new vulnerabilities affecting the TETRA standard for radio communication.

Vulnerability disclosure programs (VDPs) are structured frameworks or processes for organizations to document, submit, and report security vulnerabilities to all other relevant organizations. Being ready and able to address vulnerabilities before they become problems is an essential part of any cybersecurity strategy. While VDPs are not currently required by law, the U.S. government encourages vulnerability disclosure programs as a proactive approach to cybersecurity.
