Why aren’t there antivirus apps for the iPhone?

In recent years, the belief that iOS devices are "immune" to viruses has been challenged as cybercriminals increasingly target these platforms. Apple’s security measures, including sandboxing, help isolate apps to prevent the spread of malware. The App Store is strictly controlled, with Apple reviewing apps for security compliance, resulting in few harmful applications being reported. Antivirus software available in the App Store, from companies like McAfee and Norton, operates under the same constraints as other apps and cannot directly access the operating system kernel. Users are advised to avoid jailbreaking their devices, enable automatic updates, and take precautions such as avoiding public charging stations and regularly reviewing app permissions. Utilizing a password manager or VPN can enhance security, and those who have experienced data breaches may consider identity theft protection.

How to disable the PC webcam and protect it from unauthorized access

The webcam is a crucial tool for remote communication but poses privacy risks, particularly through a threat known as CamFecting, where unauthorized access can occur via malware, malicious websites, or system vulnerabilities. Preventive measures include using antivirus software, disabling the webcam when not in use, and physically covering the camera with privacy caps or tape. Signs of unauthorized access include unexpected illumination of the webcam light, unusual camera behavior, unknown files on the system, abnormal data consumption, and decreased battery life. To deactivate the webcam, users can adjust settings in major browsers and operating systems. Maintaining digital hygiene, such as regularly updating software, using security systems like firewalls and VPNs, and being cautious of phishing attempts, is essential to minimize risks.

Data privacy firm files complaint against Ubisoft

The European Center for Digital Rights (NOYB) has accused Ubisoft of excessive data collection practices related to the game Far Cry Primal, which may violate GDPR regulations. Players reportedly connected to external servers 150 times within ten minutes of launching the game, including connections to Google, Amazon, and Datadog. Despite being a single-player game, it requires an internet connection for ownership verification.

Mystery of the vanishing seaplane: why did Windows 11 24H2 cause the vehicle to disappear from Grand Theft Auto: San Andreas?

A coding error within Grand Theft Auto: San Andreas caused the Skimmer plane to launch into the sky after the Windows 11 24H2 update. The issue was traced to an incorrect calculation for the vehicle's Z axis in the configuration file, which had gone unnoticed until the update changed how the game processed positioning values. Prior to the update, the game read values from a previous vehicle, but the update introduced a new platform that altered this behavior, resulting in the plane receiving an excessively high Z value.

Google wants to make sure you never accidentally purchase an app again

Google is introducing a new swipe gesture for confirming app purchases on its Play Store, replacing the traditional tap-to-buy button. Users will need to hold and swipe to confirm their purchase, in addition to the usual verification measures. This feature is being rolled out in version 45.8.21-31 of the Play Store. Google has also removed 2.3 million potentially risky apps from its platform, but users are advised to remain vigilant and assess developer profiles and app reviews for reliability.

Meet Xata Agent: An Open Source Agent for Proactive PostgreSQL Monitoring, Automated Troubleshooting, and Seamless DevOps Integration

Xata Agent is an open-source AI assistant designed for PostgreSQL database site reliability engineering. It monitors logs and performance metrics to identify issues like slow queries and unusual connection counts, helping to maintain database integrity and performance. The tool automates tasks such as vacuuming and indexing and provides actionable recommendations through diagnostic playbooks and read-only SQL routines. The architecture is built as a Next.js application using TypeScript, organized in a monorepo structure. Developers can set up their environment using Node, install dependencies, and configure a local PostgreSQL instance with Docker Compose. Production deployment involves using Docker images and configuring environment variables in a production file. Key functionalities include proactive monitoring, configuration tuning, performance troubleshooting, safe diagnostics, cloud integration, alerting, LLM flexibility, and playbook customization. Developers can create new tools and integrate them into playbooks for cohesive workflows. Future plans include custom playbooks, support for Model Context Protocol, evaluation harnesses, approval workflows, and a managed cloud edition. The architecture promotes extensibility and community contributions, standardizing incident response and reducing human error in database management.

Best practices to handle AWS DMS tasks during PostgreSQL upgrades

The AWS Database Migration Service (AWS DMS) provides a managed solution for migrating and replicating databases to AWS, supporting both homogeneous and heterogeneous migrations. It allows seamless data migration from PostgreSQL databases to any supported target and vice versa. Open-source PostgreSQL regularly releases new versions, and Amazon RDS aims to support these within five months. Upgrading PostgreSQL instances is essential for security and compliance. Minor version upgrades focus on security and bug fixes without adding new functionalities, while major upgrades can change system tables and data formats. AWS DMS tasks require careful management during PostgreSQL upgrades. For minor upgrades, ongoing DMS tasks should be stopped and then resumed post-upgrade. For major upgrades, replication slots must be dropped before the upgrade, which will invalidate ongoing DMS tasks. After the upgrade, a new CDC-only task should be created to resume data migration. Minor version upgrades of the target PostgreSQL database do not affect AWS DMS CDC tasks, but major upgrades require stopping the DMS task, performing the upgrade, and ensuring compatibility with the replication instance before resuming the task.

N.J. attorney general sues Discord messaging app over child predator concerns

New Jersey has filed a lawsuit against Discord, claiming the platform fails to adequately protect underage users from predators, thus breaching the New Jersey Consumer Fraud Act. The lawsuit highlights that children can easily create accounts without proper age verification, allowing adult users to contact them. New Jersey Attorney General Matthew Platkin criticized Discord's safety measures, stating they can be easily bypassed. In 2023, an NBC News investigation linked 35 cases of serious crimes to interactions on Discord. Discord’s CEO acknowledged the severity of these issues and announced updates to child safety policies, including a ban on teen dating and AI-generated child sexual abuse material.

Google hit with antitrust order in Japan over preinstalled Android apps

Japan's Fair Trade Commission (JFTC) has issued a cease-and-desist order against Google for violating the nation's anti-monopoly law by requiring smartphone manufacturers to preinstall its applications on Android devices. This practice has been in place since at least July 2020 and has hindered competition by making it difficult for rival search engines and browsers to gain a foothold on Android devices sold in Japan. The JFTC found that Google's contracts incentivized manufacturers to set Google Chrome as the default browser and not preinstall competing applications, affecting around 80 percent of Android smartphones in Japan. The JFTC classified these actions as violations of the Antimonopoly Act and mandated Google to stop these practices, develop compliance guidelines, and appoint an independent third party to oversee adherence to the order. Non-compliance could result in significant financial penalties. Google expressed disappointment but indicated a willingness to collaborate with the JFTC.
