AKDAN Malware Hunters blocks new malware that are difficult to detect with existing Antivirus with ‘AKDAN HALL’

AKDAN Malware Hunters has launched the AKDAN HALL PED, a security solution that detects and neutralizes unknown document-based malware in 0.27 seconds, achieving a 99% success rate against emerging threats. This technology uses Pre-Execution Detection (PED) and a virtual "hypnosis" environment to analyze potentially malicious behavior, differing from traditional antivirus software that relies on known threat databases. CEO Sean Jeon, with over 15 years in cybersecurity, emphasizes the need for proactive measures as 91% of cyberattacks start via email, often using document-based malware. The AKDAN HALL product line includes a cloud-based agent for personal use and the AKDAN HALL Mini, a compact server for sensitive environments, both designed to complement existing antivirus solutions. The company has received support from the Initial Startup Package program at Seoul National University of Science and Technology and plans to expand into the Japanese market.

Registry hack enables new performance-boosting native NVMe support on Windows 11 — Windows Server 2025 feature can be unlocked for consumer PCs, but at your own risk

Microsoft has announced that Windows Server 2025 will offer native support for NVMe drives. Early adopters have reported performance improvements of 10% to 15%, including reduced latencies and enhanced transfer speeds. The native support allows for 64,000 queues, each managing 64,000 commands simultaneously, enabling over 4 billion operations, compared to existing SCSI protocols that limit queues to 32 commands. Not all users have experienced performance benefits, and Microsoft recommends backing up systems or testing in a virtual environment before enabling this feature.

How Letta builds production-ready AI agents with Amazon Aurora PostgreSQL

AI agents benefit from persistent memory, enabling them to recall past interactions and maintain context, which enhances customer experience in scenarios like customer service. The Letta Developer Platform allows developers to create stateful agents with advanced context management features. It supports self-hosting within a virtual private cloud and uses Amazon Aurora PostgreSQL for long-term memory storage. Aurora PostgreSQL offers capabilities such as efficient similarity searches with the pgvector extension, sub-second query latency, and dynamic storage scaling. Letta operates as a persistent service, allowing agents to function independently and scale horizontally using Kubernetes. The platform supports multi-tenancy and includes enterprise features for security and monitoring. To set up an Aurora Serverless cluster for Letta, users must create a database on Amazon RDS, configure security group access, and install the pgvector extension. Letta connects to Aurora using a PostgreSQL connection string. After establishing the connection, users can create agents, send messages, and view agent states and conversation histories stored in Aurora. Letta organizes data in 42 tables, including those for agents, messages, and memory blocks. Users can explore the database schema and examine the structure of stored messages and embeddings. Finally, it is recommended to delete the Aurora cluster and associated resources after completing the integration to avoid charges.

Russian hackers abuse Hyper-V to hide malware in Linux VMs

The Russian hacker group Curly COMrades has been using Microsoft Hyper-V to bypass endpoint detection and response (EDR) solutions by creating a concealed Alpine Linux-based virtual machine for running malware. They have deployed proprietary tools, CurlyShell and CurlCat, within this virtual environment to maintain operational stealth and secure communication. Active since mid-2024, the group targets government and judicial entities in Georgia and energy companies in Moldova. In early July, they gained remote access to two machines, activated Hyper-V, and disabled its management interface to deploy a minimalistic virtual machine that hosted their malware. This tactic allowed them to evade traditional host-based EDR detections. The virtual machine was configured to use the Default Switch network adapter, making malicious traffic appear to originate from the legitimate host's IP address. CurlyShell executes commands and maintains persistence, while CurlCat facilitates covert traffic tunneling. The group also utilized PowerShell scripts for persistence and pivoting to remote systems, including injecting Kerberos tickets into LSASS and creating local accounts via Group Policy. Bitdefender advises organizations to monitor for abnormal Hyper-V activation, LSASS access, and suspicious PowerShell scripts.
