Why Anti Malware and Antivirus Solutions still matter despite Google Play Protect

Google Play Protect is a security feature integrated within the Google Play Store that scans installed applications for malicious behavior, verifies apps before download, and can disable or remove harmful software. Its primary limitation is its focus on apps from the Google Play Store, leaving users who install APK files from third-party sources at risk. Modern cyber threats include phishing links, counterfeit login pages, and social engineering techniques, which Google Play Protect does not fully address. Dedicated antivirus applications offer real-time threat detection, privacy protection, and additional features such as monitoring excessive app permissions and dark web credential leaks. For business users, mobile security platforms provide advanced capabilities like enforcing corporate policies and detecting zero-day threats. While Google Play Protect is sufficient for many users, those handling sensitive information or seeking enhanced protection should consider additional antivirus solutions. Best practices for cybersecurity include downloading apps from trusted sources, keeping software updated, and using strong passwords.

Why most AI projects fail: It’s infrastructure and people

AI technology faces significant criticism for its low success rates in delivering business results, with studies indicating a 95% failure rate for enterprise AI solutions and only 9% of organizations in Europe, the Middle East, and Africa achieving measurable outcomes from AI initiatives. Four main shortcomings hinder the transition of AI prototypes to production: 1. Deployment Flexibility: Prototyping environments often lack the necessary flexibility for large-scale production deployment, particularly in regulated sectors. 2. Data Sovereignty: Production transitions can complicate data sovereignty at enterprise and regional levels. 3. Reliability: High availability is crucial for production environments, but vendor-managed platforms may not guarantee seamless upgrades or hardware swaps without downtime. 4. Disconnect in Tool Selection: Developers often choose tools for prototyping without considering production implications, leading to difficulties in scaling. The shortage of database administrators (DBAs) is exacerbated by the increasing use of AI tools, with 84% of developers utilizing them according to a 2025 survey. To address these challenges, Merrick suggests leveraging AI DBA agents to support human DBAs and improve database management efficiency. He emphasizes the need for both robust data infrastructure and enhanced operational support to improve the success rates of AI prototypes.

Why Antivirus Alone No Longer Protects Small Businesses

Many small businesses have historically relied on antivirus software for computer security, which was effective against identifiable malware. However, the current cyber threat landscape includes sophisticated attacks such as phishing, credential theft, and ransomware that traditional antivirus solutions may not adequately address. Factors driving increased cyber threats in Kenya include phishing, weak authentication practices, delayed software updates, and the use of artificial intelligence by malicious actors. While antivirus software can detect known malware and block common threats, it falls short against tactics like stolen credentials and social engineering. The Communications Authority recommends complementing antivirus with multi-factor authentication, regular software updates, secure configurations, and user training. Endpoint Detection and Response (EDR) solutions enhance visibility into attacks by monitoring endpoint activity for suspicious behaviors, allowing for prompt investigation and response. A layered security strategy that integrates multiple protective measures is essential for effective cybersecurity, and many modern security platforms offer unified solutions to simplify management for smaller organizations. The Kaspersky SMB Cybersecurity Guide provides insights into modern attack methods and the role of endpoint protection in improving a business's cybersecurity posture.

Hackers Use Fake VLC Executable and Malicious libvlc.dll to Deploy ValleyRAT

Cybercriminals are using a sophisticated method to bypass security measures by embedding malware within the VLC media player. This campaign exploits VLC to install ValleyRAT, a remote access trojan, through phishing emails that contain links to download a seemingly harmless file. Once the file is opened, it activates a hidden backdoor that evades detection by antivirus solutions. The malware has been active since 2023, with a significant increase in activity noted through 2025 and into 2026, particularly targeting Chinese and Japanese-speaking users. The infection process begins when a victim clicks a link in a phishing email, leading to a ZIP archive containing a disguised executable and a malicious DLL (libvlc.dll). The executable mimics a legitimate VLC file, and when executed, it loads the DLL, allowing the malware to run under the guise of VLC. The malware establishes persistence by creating a registry entry and connects to a remote server to retrieve the final payload. ValleyRAT employs evasion tactics to avoid detection, such as performing checks on system behavior and using a fileless approach to inject its payload directly into memory, avoiding storage on disk. Researchers recommend training employees to recognize suspicious filenames and deploying endpoint detection tools to identify DLL sideloading behavior. For organizations affected by this campaign, isolating compromised systems and reviewing security logs are critical initial steps. Indicators of compromise include a malicious email domain, a ZIP archive containing a fake VLC executable, and a download URL for ValleyRAT.

From monolith to Lakebase to LTAP: rethinking the database from storage up

Sixteen years ago, the author began their PhD at UC Berkeley and was advised to focus on analytics rather than OLTP databases, which were considered solved. This led to the creation of Apache Spark and Databricks. However, during the development of Databricks, it was found that OLTP databases were not solved problems; they were difficult to scale and fragile. This realization led to the development of Lakebase, a serverless Postgres database designed with modern technology. Lakebase architecture separates the write-ahead log (WAL) and data files into independent, scalable services. The WAL is externalized to a service called SafeKeeper, which uses Paxos-based replication for durability, while data files are managed by PageServer, which stores them in cloud object storage. This design addresses challenges such as data loss, scaling, and performance interference between transactional and analytical workloads. Lakebase maintains compatibility with Postgres, offers unlimited storage, serverless compute, durable writes, and simpler high availability. It also introduces LTAP (Lake Transactional/Analytical Processing), which allows both transactional and analytical processing to operate on a single data copy in real time, eliminating the need for separate data copies and reducing costs. LTAP utilizes a unified storage layer that allows data to be materialized in both row and columnar formats, optimizing it for both transactional and analytical workloads. The system ensures that analytics can access the most current data without affecting transactional performance by using a log sequence number (LSN) to retrieve the latest changes. Unlike traditional CDC approaches, LTAP requires no explicit table replication, as all data is stored in a single governed copy. This architecture circumvents common issues faced by hybrid transactional/analytical processing (HTAP) systems, such as incomplete feature sets, lack of ecosystem support, and performance contention. The Lakebase architecture has unlocked capabilities like unlimited storage, elastic compute, durable writes, and instant branching, with ongoing developments anticipated in the future.

Sixteen years ago, the author began their PhD at UC Berkeley, where they were advised to focus on analytics rather than OLTP databases, which were considered a solved problem. However, upon developing Databricks, they found that OLTP databases were cumbersome, challenging to scale, and fragile. This led to the creation of Lakebase, a serverless Postgres database designed to address these issues by externalizing the write-ahead log (WAL) and data files into independent services. Lakebase architecture separates the WAL into a distributed service called SafeKeeper and data files into another service called PageServer, allowing for improved durability, scalability, and performance. This architecture eliminates data loss risks associated with disk failures and misconfigurations, simplifies high availability, and allows for elastic compute resources. Lakebase also introduces LTAP (Lake Transactional/Analytical Processing), which enables transactions and analytics to operate on a single data copy in real-time, avoiding the need for separate data copies and reducing costs. The system retains Postgres's ACID semantics while storing data in open columnar formats, making it accessible to both transactional and analytical engines without the delays and complexities of traditional replication methods. The architecture allows for unlimited storage, serverless compute, and instant branching, while ensuring that analytics can read the most current transactional data without affecting transactional workloads. LTAP aims to unify transactional and analytical processing by leveraging distinct compute engines for each workload while integrating at the storage layer.

Google swears (again) that data-sharing rules will help scammers, threaten your search history

Google is opposing the European Union's proposed amendments to the Digital Markets Act (DMA), warning that these changes could jeopardize user privacy and security. The DMA aims to reduce the dominance of major tech platforms by requiring gatekeepers like Google to share more data with competitors. Google is particularly concerned about the implications of sharing search data and granting third-party AI services access to sensitive Android features, fearing that this could lead to increased fraud and cyberattacks. The European Commission is pushing for Google to provide rival search engines with access to anonymized search data to enhance competition, but Google argues that once this data leaves its infrastructure, it becomes difficult to protect. DuckDuckGo and some researchers believe the Commission's proposals adequately address privacy risks, while others acknowledge the risks but suggest they should be balanced against technical protections. Additionally, EU regulators are advocating for deeper integration of competing AI assistants with Android, which Google warns could compromise existing security measures. Apple has shown support for some of Google's concerns regarding access to operating systems.
