Atlassian has released software fixes to address  four critical flaws  in its software that, if successfully exploited, could result in remote code execution. The list of vulnerabilities is below - CVE-2022-1471  (CVSS score: 9.8) - Deserialization vulnerability in  SnakeYAML library  that can lead to remote code execution in multiple products CVE-2023-22522  (CVSS score: 9.0) - Remote code execution vulnerability in Confluence Data Center and Confluence Server (affects all versions including and after 4.0.0) CVE-2023-22523  (CVSS score: 9.8) - Remote code execution vulnerability in Assets Discovery for Jira Service Management Cloud, Server, and Data Center (affects all versions up to but not including 3.2.0-cloud / 6.2.0 data center and server) CVE-2023-22524  (CVSS score: 9.6) - Remote code execution vulnerability in Atlassian Companion app for macOS (affects all versions up to but not including 2.0.0) Atlassian described CVE-2023-22522...

Microsoft has disclosed details of a now-patched security flaw in Apple macOS that could be exploited by an attacker to get around security protections imposed to prevent the execution of malicious applications. The shortcoming, dubbed  Achilles  ( CVE-2022-42821 , CVSS score: 5.5), was addressed by the iPhone maker in  macOS Ventura 13 ,  Monterey 12.6.2 , and  Big Sur 11.7.2 , describing it as a logic issue that could be weaponized by an app to circumvent Gatekeeper checks. "Gatekeeper bypasses such as this could be leveraged as a vector for initial access by malware and other threats and could help increase the success rate of malicious campaigns and attacks on macOS," Jonathan Bar Or of the Microsoft 365 Defender Research Team  said . Gatekeeper is a  security mechanism  designed to ensure that only trusted apps run on the operating system. This is  enforced  by means of an extended attribute called "com.apple.quarantine" that's...

In recent years, artificial intelligence (AI) has begun revolutionizing Identity Access Management (IAM), reshaping how cybersecurity is approached in this crucial field. Leveraging AI in IAM is about tapping into its analytical capabilities to monitor access patterns and identify anomalies that could signal a potential security breach. The focus has expanded beyond merely managing human identities — now, autonomous systems, APIs, and connected devices also fall within the realm of AI-driven IAM, creating a dynamic security ecosystem that adapts and evolves in response to sophisticated cyber threats. The Role of AI and Machine Learning in IAM AI and machine learning (ML) are creating a more robust, proactive IAM system that continuously learns from the environment to enhance security. Let's explore how AI impacts key IAM components: Intelligent Monitoring and Anomaly Detection AI enables continuous monitoring of both human and non-human identities , including APIs, service acc...

Apple recently fixed a security vulnerability in the macOS operating system that could be potentially exploited by a threat actor to "trivially and reliably" bypass a "myriad of foundational macOS security mechanisms" and run arbitrary code. Security researcher Patrick Wardle  detailed  the discovery in a series of tweets on Thursday. Tracked as CVE-2021-30853 (CVSS score: 5.5), the issue relates to a scenario where a rogue macOS app may circumvent  Gatekeeper  checks, which ensure that only trusted apps can be run and that they have passed an automated process called " app notarization ." The iPhone maker, crediting Gordon Long of Box with reporting the flaw, said it  addressed the weakness  with improved checks as part of macOS 11.6 updates officially released on September 20, 2021. "Such bugs are often particularly impactful to everyday macOS users as they provide a means for adware and malware authors to sidestep macOS security mechanisms, …m...
