Protect sensitive data with dynamic data masking for Amazon Aurora PostgreSQL

Amazon Aurora PostgreSQL-Compatible Edition has introduced a dynamic data masking feature that provides column-level protection, enhancing security alongside PostgreSQL’s row-level security. This feature is available for Aurora PostgreSQL versions 16.10 and higher, as well as 17.6. Dynamic data masking allows organizations to maintain a single copy of their data while applying role-based access controls, ensuring sensitive information is protected in real-time without data duplication. The pg_columnmask extension enables policy-based masking and runtime query rewriting, allowing different users to see varying levels of data based on their roles. For example, customer service representatives may see only the last four digits of account numbers, while executives see full details. The feature supports compliance with regulations such as GDPR, HIPAA, and PCI DSS. Users can create masking policies using standard SQL commands, and the policies can be defined to utilize built-in or custom functions for data masking.

Percona Brings Transparent Data Encryption to Postgres

Percona introduced an open-source Transparent Data Encryption (TDE) extension for its PostgreSQL distribution at KubeCon+CloudNativeCon North America, addressing the demand for data protection solutions, particularly among financial institutions concerned about vendor lock-in. The TDE extension, named pg_tde, operates transparently, allowing users to input and query data without changes to interactions or schemas, while unauthorized access reveals only encrypted information. It supports all major key management services and is included in Percona's PostgreSQL distribution without additional licensing fees. The TDE solution helps organizations comply with standards like GDPR, HIPAA, SOX, and PCI DSS v4.0, offering benefits such as open-source readiness, stronger data protection, user-controlled encryption, seamless integration, centralized key management, effortless online encryption, and trusted support. Percona also offers solutions for MySQL and MongoDB and supports emerging technologies like Valkey.

Why Your Apple Device Isn’t as Invincible as You Think

Many Apple users believe that their devices are nearly impervious to malware and cyber threats, but this is a misconception. While macOS has built-in protections like Gatekeeper and XProtect, no system is completely foolproof. Cybercriminals are increasingly targeting Macs, and users can fall victim to phishing schemes, ransomware, and other malware. Antivirus software for Mac provides an additional layer of defense, detecting malware and blocking phishing attempts. It can also protect sensitive information and offer features like secure browsing and Wi-Fi protection. Regular software updates and cautious behavior are essential for security, but relying solely on these measures is risky. Integrating antivirus into security routines is a practical step to minimize risks.

How to implement Dynamic SQL in PostgreSQL 10

Dynamic SQL in PostgreSQL allows developers to streamline querying processes and reduce repetitive tasks. It is implemented using the EXECUTE statement, which evaluates a string input. Dynamic SQL can be used for executing DDL statements, such as analyzing tables within a schema, and for DML statements, enabling interactive data manipulation, like filtering results in a billing application. PL/pgSQL caching can lead to inefficiencies in dynamic SQL scenarios where execution plans vary. Security risks, particularly SQL injection vulnerabilities, are associated with dynamic SQL. Recommended practices to mitigate these risks include using the USING clause for parameterized statements, employing the format function for query construction, and utilizing functions like quote_ident() and quote_literal() for proper formatting.

Windows Is Becoming An Operating System For AI Agents

Microsoft Windows is evolving to incorporate AI agents that act autonomously, resembling digital coworkers. This shift is facilitated by the Model Context Protocol (MCP), which standardizes agent interactions with tools and data sources, ensuring secure access to system resources. Windows introduces an on-device registry of "agent connectors" for functionalities like file access and system settings, managed through an OS-level proxy that oversees identity, permissions, consent, and audit logging. The initial connectors focus on File Explorer and System Settings, defining clear capabilities and restrictions for agents. A transparent consent model allows users to manage permissions easily, promoting a user-friendly experience. The introduction of an Agent Workspace provides a dedicated environment for agents, ensuring they operate independently and with least-privileged access. Security measures include signed connectors and a standardized proxy for authentication and auditing, enabling visibility into agent actions. Windows is also expanding on-device AI processing with APIs for various functionalities, allowing agents to leverage local models securely. While Windows is not becoming an agent-first operating system, it is establishing a framework for human and agent interactions, positioning itself as a safe environment for AI operations. The foundational elements for this evolution include standard interfaces, clear permissions, isolated environments, and system-level observability.

JSON services hijacked by North Korean hackers to send out malware

The Lazarus Group, a North Korean state-sponsored hacking organization, has been using JSON storage services like JSON Keeper, JSONsilo, and npoint.io to host malicious software. They lure victims through deceptive LinkedIn job offers to deploy malware such as BeaverTail, InvisibleFerret, and TsunamiKit, the latter being a multi-stage toolkit that can act as an information stealer or cryptojacker by installing XMRig to mine Monero. Additional malware variants like Tropidoor and AkdoorTea have been deployed through the BeaverTrail framework, targeting software developers for sensitive data and crypto wallet information. The group's use of legitimate websites and code repositories aims to blend malicious activities with normal internet traffic, increasing their chances of success and posing a significant cybersecurity threat.

Warning Issued As Hackers Give Microsoft Windows The Finger: Report

Cybercriminals are using a tactic called ClickFix, which exploits the finger command to target Microsoft Windows users. This method involves social engineering, tricking users into interacting with a fraudulent captcha that prompts them to enter commands into the Windows run dialog. The execution of the finger command can provide attackers with sensitive information such as login names, home directory details, phone numbers, and user activity logs. Currently, this trend appears to be driven by a single threat actor, but the potential for widespread victimization is significant. Users should be cautious if a captcha requests them to enter commands, as this is not a standard practice.

UK’s £312M Windows 10 Fiasco: Upgrading to Obsolescence on EOL’s Doorstep

The UK’s Department for Environment, Food and Rural Affairs (Defra) has allocated £312 million to upgrade its IT systems to Windows 10, just months before Microsoft ends support for the operating system on October 14, 2025. Defra faces challenges in migrating thousands of devices, with 24,000 outdated machines incompatible with newer systems. A survey indicates that 90% of UK finance firms also struggle with outdated IT infrastructure, increasing cybersecurity risks. The National Cyber Security Centre has warned organizations to prepare for migrations to Windows 11. Defra's £312 million expenditure includes software licenses, consulting fees, and hardware refreshes, but additional risks such as increased downtime and regulatory fines could lead to significant consequences. The department's outdated devices do not meet Windows 11’s TPM 2.0 requirements, complicating the upgrade process. Experts advocate for an upgrade to Windows 11, but extensive compatibility testing and user training are necessary. Government oversight bodies are scrutinizing Defra’s expenditures, and discussions suggest alternatives like Windows 10 IoT Enterprise LTSC, which offers updates until 2032. The financial implications of Microsoft’s Extended Security Updates pricing add strain, as costs double in subsequent years. The urgency for upgrades is emphasized by the potential cybersecurity risks, with experts warning of vulnerabilities affecting national food security and environmental initiatives.
