Iranian state-affiliated cyber actors are targeting dissidents, activists, and journalists using fake AI applications, counterfeit antivirus tools, and fabricated MRI scan results, primarily through a spyware family known as CHOSEN BRICK, which is designed for Windows systems. This campaign has been active since at least 2025 and affects individuals globally, including in the UK, US, and Netherlands. The malware establishes persistence via the Windows Registry Run key and communicates through Telegram, utilizing unique Bot IDs for each victim. CHOSEN BRICK is capable of extensive data collection, including capturing screenshots, recording audio, and stealing email content. Personal information from victims has been found on pro-Iranian leak sites, increasing harassment risks. Security measures should include monitoring for suspicious Registry entries and unusual communications, while users are advised to avoid unsolicited software installations and keep their systems updated. The FBI refers to this malware family as HEAVYGRAM.

The encryption landscape has shifted significantly, with Microsoft’s BitLocker and Apple’s FileVault becoming the primary free and integrated solutions for disk encryption. Organizations are encouraged to focus on comprehensive management capabilities rather than just acquiring encryption technology. Key management, compliance proof for auditors, and consistent policy enforcement across devices are critical. Native encryption solutions do not provide fleet-wide compliance, centralized key escrow, or advanced pre-boot authentication options. Various management models exist for different organizational needs, including options from Microsoft, Sophos, ESET, Trend Micro, Check Point, Trellix, WinMagic, Broadcom (Symantec), Dell, and Kaspersky. It is essential to ensure proper key management and recovery procedures before enforcing encryption to avoid data loss. Organizations should verify claims of compatibility and effectiveness of encryption solutions, especially regarding pre-boot authentication and cryptographic standards. Native encryption solutions are free, but management layers typically incur costs. Open-source solutions like VeraCrypt lack necessary management features, making them impractical for businesses.

The landscape of encryption engines has stabilized, with Microsoft BitLocker and Apple FileVault being the primary solutions. As of 2026, the emphasis is on management rather than just acquiring encryption technology. Key management elements include audit proofing, key escrow and recovery, policy enforcement, and pre-boot options. Native encryption solutions lack features such as fleet-wide compliance proof, centralized key escrow, consistent policy enforcement, advanced pre-boot authentication, and removable-media encryption. Various management models are available for different environments, including: 1. Microsoft BitLocker with Intune: Free for Windows Pro/Enterprise, integrates with Entra ID for key management. 2. Sophos: Manages both BitLocker and FileVault from a single console. 3. ESET: Offers lightweight management and removable-media protection. 4. Trend Micro: Integrates encryption with DLP capabilities. 5. Check Point: Provides advanced pre-boot options and policy management. 6. Trellix: Comprehensive enterprise encryption suite with a complex management interface. 7. WinMagic: Focuses on cross-platform encryption and strong pre-boot options. 8. Broadcom (Symantec): Manages native engines within its broader security framework. 9. Dell: OEM-integrated encryption management for Dell hardware. 10. Kaspersky: Provides encryption management but is restricted in the U.S. Key considerations before deploying encryption include ensuring key escrow is in place, conducting recovery tests, and being mindful of removable media and server encryption. Common mistakes include using outdated freeware and not verifying key escrow. Organizations should request auditor reports for compliance verification and confirm claims of compatibility and pre-boot functionality. Native encryption engines are free, while management layers typically charge on a per-endpoint basis.

If you hold Microsoft 365 E5, you already have access to Microsoft Defender for Endpoint, which provides enterprise-grade endpoint protection at no additional cost. For organizations without a dedicated security specialist, Sophos is recommended. CrowdStrike is suitable for those with a mature Security Operations Center (SOC) and sufficient budget. Other options include SentinelOne for mid-sized organizations needing automation, ESET for older hardware and virtual desktops, Avast Business for very small businesses without IT staff, VIPRE for budget-conscious organizations, and Expel for tool-agnostic managed detection and response. It is essential to assess your organization's current situation honestly when evaluating endpoint protection options. Antivirus and EDR are now essentially the same agent, and organizations should inquire about update staging processes and review independent tests for protection rates. Coverage for servers and Linux environments is often overlooked but crucial, as Linux servers are prime targets for ransomware. Key recommendations include: - Microsoft Defender for Endpoint for organizations already on Microsoft 365 E5. - Sophos for organizations with 25-500 staff relying on IT generalists. - CrowdStrike for enterprises with a well-funded security operations function. - SentinelOne for mid-sized organizations needing autonomous operation. - ESET for organizations with older hardware or virtual desktop infrastructure. - Avast Business for micro and small businesses. - VIPRE for budget-conscious organizations. - Expel for those seeking managed detection across various environments. During deployment, avoid running two real-time agents simultaneously, ensure prevention features are activated, and test on line-of-business applications first. Verify update staging and rollback procedures with vendors, and confirm whether Microsoft licensing covers your needs to avoid unnecessary purchases.

Lakebase Postgres employs a disaggregated storage model that enhances data management through efficient caching, utilizing an object store like S3 for backups. The caching operates on two layers: within distributed storage for optimizing write and read performance, and on the Postgres compute side for ultra-fast access to frequently accessed pages. Traditional Postgres caching involves shared buffers and the OS page cache, which leads to double buffering and inefficiencies. Lakebase Postgres addresses these issues by implementing a local file cache (LFC) and larger shared buffers, allowing for more effective memory utilization without the drawbacks of the OS page cache. The shared buffers are set to a maximum of 1 GB, while the LFC can utilize up to 75% of DRAM. The introduction of huge pages reduces memory management overhead and improves performance, resulting in significant throughput increases and reduced latency in production environments. Recent enhancements have shown up to 2× throughput improvements and substantial reductions in CPU usage. The focus is now on extending these benefits to autoscaling Postgres computes, with plans to implement dynamic shared buffers and autoscaling huge pages.

Microsoft BitLocker and Apple FileVault are free, integrated encryption solutions within their respective operating systems. As of 2026, the focus is on investing in management solutions that provide compliance proof, key escrow, recovery options, and policy enforcement across devices. Native encryption solutions lack certain management features, prompting the need for additional management layers from various vendors. Legacy freeware like TrueCrypt is no longer maintained, posing risks for business use, while VeraCrypt is a credible open-source alternative but lacks centralized management. Management options include Microsoft Intune for Windows, Sophos for mixed fleets, and specialized providers like Check Point and WinMagic for advanced needs. Organizations should ensure proper key management before enforcing encryption to avoid data loss and regularly test recovery processes. It is crucial to verify claims regarding compatibility and pre-boot options when selecting encryption solutions. Native engines are free, but management layers typically charge per endpoint annually.
