Good Morning and Happy Friday - Your weekly sip of cybersecurity news from the Cybersec Cafe: Phishing campaigns continue to be a world-wide threat. DoS attacks are distributing themselves to different vulnerable software. The “good guys” continue to find new ways to keep malicious actors out of the business of consumers.
Urgent Security Alert: XZ Utils Library Backdoored - Take Action Now!
Red Hat recently issued an urgent security alert, revealing that two versions of the XZ Utils library have been compromised with malicious code.
These compromised versions, 5.6.0 and 5.6.1, pose a severe risk of unauthorized remote access to affected systems, potentially allowing threat actors to intercept and modify data interactions, thus enabling unauthorized access via SSH under specific conditions.
This security vulnerability is critical for organizations to grasp, especially those using the impacted XZ Utils versions, as prompt action is needed to mitigate the risk of exploitation by malicious actors.
System administrators and Linux users should be particularly attentive, ensuring to downgrade to uncompromised versions of XZ Utils and closely monitor any virtual machines, especially those updated within the last week.
Stay vigilant for further developments and security advisories related to this issue to safeguard your systems effectively.

Minecraft, with its vast user base, is under significant risk from distributed denial-of-service (DDoS) attacks, jeopardizing server functionality, player experience, and the game's reputation.
DDoS attacks disrupt gameplay, causing issues such as lag, disconnections, and server crashes, leading to financial and reputational losses for server owners and operators. Understanding these risks is crucial for Minecraft players, server owners, and administrators to safeguard against potential threats.
Implementing basic protective measures like antivirus software and staying informed about DDoS tactics can help mitigate these risks, while considering advanced protective measures such as specialized DDoS protection services can ensure uninterrupted gameplay and server security
Security Flaw Found in LayerSlider Plugin for WordPress
A critical security flaw, identified as CVE-2024-2879, has been uncovered in the LayerSlider plugin for WordPress.
This vulnerability affects versions 7.9.11 through 7.10.0, allowing unauthenticated attackers to exploit SQL injection to gain access to sensitive database information.

Google Introduces Device Bound Session Credentials to Combat Cookie Theft
Google has launched a new feature in Chrome called Device Bound Session Credentials (DBSC) to address the threat of session cookie theft by malware.
DBSC, currently in testing with select Chrome Beta users, aims to disrupt the cookie theft industry by binding authentication sessions to users' devices. This approach makes stolen cookies worthless to attackers, as they are tied to specific devices, thereby thwarting attempts to hijack accounts.
Understanding DBSC's role in enhancing security against session hijacking techniques is essential for safeguarding user data and privacy. Chrome users should stay informed about DBSC's development and consider enabling Enhanced Safe Browsing to protect their online accounts from unauthorized access by malicious actors.
Beware of the HTTP/2 CONTINUATION Flood
A new vulnerability in the HTTP/2 protocol's CONTINUATION frame has been discovered, posing a serious threat of denial-of-service (DoS) attacks.
Dubbed the HTTP/2 CONTINUATION Flood, the flaw allows attackers to flood a target server with CONTINUATION frames, potentially causing it to crash or suffer performance degradation.
This vulnerability affects various projects, including amphp/http, Apache HTTP Server, Apache Tomcat, Apache Traffic Server, Envoy proxy, Golang, h2 Rust crate, nghttp2, Node.js, and Tempesta FW.
Users are urged to upgrade affected software to the latest version or consider temporarily disabling HTTP/2 to mitigate the risk of exploitation.
