I Turned Off All Antivirus Protection for a Week. Here’s What I Learned

The author conducted an experiment by disabling both Bitdefender and Windows Security for a week to rely solely on personal cybersecurity instincts. They took precautions by using a secondary device and backing up important data. Throughout the week, the author experienced heightened awareness while navigating online tasks, encountered a phishing email, and adapted to a more deliberate browsing rhythm. Key takeaways included exercising caution, verifying sources, being aware of URLs, and keeping software updated. The experiment highlighted the importance of both good habits and antivirus software in maintaining cybersecurity. The author concluded that while personal vigilance is crucial, antivirus software is essential for those lacking strong instincts.

PostgreSQL 18 on Amazon Aurora and Amazon RDS: Security, monitoring, and developer enhancements

PostgreSQL version 18 has deprecated MD5 password authentication in favor of SCRAM-SHA-256, with a new parameter, md5_password_warnings, enabled by default to log deprecation warnings. It has enhanced monitoring capabilities by adding columns to pg_stat_database and pg_stat_statements to track parallel worker activity, with the default max_parallel_workers_per_gather set to 0 in Aurora PostgreSQL. The pg_stat_subscription_stats view now includes new columns for tracking conflict types in logical replication. Optimizer statistics are automatically transferred during upgrades, while uuidv7() generates timestamp-ordered UUIDs. The default streaming option for CREATE SUBSCRIPTION has changed to parallel, and the idle_replication_slot_timeout parameter automatically invalidates inactive replication slots. Enhancements to the COPY command include REJECT_LIMIT for error tolerance and a silent LOG_VERBOSITY level. OLD and NEW aliases have been introduced in RETURNING clauses for various DML commands.

Rokarolla trojan uses screen overlays to hijack Android financial apps

A new banking trojan for Android, named Rokarolla, targets 217 applications, including banking and cryptocurrency platforms, to steal credentials and sensitive financial data. It operates via a command and control (C2) server and bypasses the Google Play Store by using phishing websites that mimic legitimate download portals. Users are tricked into downloading a dropper that installs the malware, which disguises itself as the Google Play Protect security tool to gain access to Android Accessibility Services. Rokarolla employs dynamic screen overlays to capture user input in targeted financial applications and can also impersonate the device's lock screen. Additionally, it uses a pseudo-VNC system to intermittently capture screenshots for data extraction and can modify clipboard contents to manipulate cryptocurrency transactions by replacing copied addresses with those controlled by attackers.

How Your Location Influences Android App Availability

The Google Play Store customizes its app offerings based on the user's location, which affects app availability and functionality. App developers often set distribution rules that vary by region, leading to differences in user experience even for identical apps. Android devices determine location through a combination of signals, including SIM card data, GPS, and Wi-Fi positioning. Connectivity issues, particularly in rural areas, can limit app usability, while social habits influence regional app demand. Developers analyze engagement data to adapt their offerings based on regional preferences, creating a feedback loop that affects app visibility and features. Users should verify app functionality based on their location and connectivity before assuming an app's absence is due to obscurity.

Why Oracle’s OCI Database with PostgreSQL matters for serious workloads

Oracle has launched the OCI Database with PostgreSQL, a managed PostgreSQL service designed for seamless deployment within the Oracle Cloud. This service includes lifecycle management, automated backups, and monitoring, allowing users to customize their database configurations easily. A key feature is the cross-region warm standby, which enhances disaster recovery by enabling users to create replica databases in secondary regions that replicate data from the primary database. The service enforces a strict 5-minute recovery point objective (RPO) and simplifies the setup process for operations teams. The OCI Database with PostgreSQL is positioned against offerings from AWS and Azure, targeting organizations that prefer a managed PostgreSQL experience. However, compliance challenges, such as the lack of FedRAMP certification, may hinder adoption for certain sectors. The product is available on OCI with usage-based pricing and is aimed at cloud teams needing managed operations and disaster recovery for PostgreSQL databases.

Xbox is porting two classic Call of Duty games to PlayStation — and they’re coming very, very soon

Treyarch announced that Call of Duty: Black Ops (2010) and Call of Duty: Black Ops 2 (2012) will be ported to PlayStation platforms, likely for PS4 and PS5, starting in July. Iron Galaxy Studios will handle the modernization of these titles. The games have been available on Xbox One and Xbox Series X|S since 2016 through Microsoft's Backwards Compatibility Program. There are uncertainties about whether existing PS3 owners will access the new versions for free or transfer their progress. The new ports are expected to integrate with the existing server network. Xbox and PC players have expressed frustration over issues with Black Ops and Black Ops 2 on Xbox, including a locked 720p resolution and hacking problems, as well as the absence of these titles on Xbox Game Pass.

Dishonored dev defends loading screens: ‘I actually have a soft spot for all that’

Raphaël Colantonio, co-creative director of Dishonored, streamed a session revisiting the game's level, Lady Boyle's Last Party, with team members including Harvey Smith, Stevan Hird, and Anthony Huso. During the session, Smith defended the inclusion of loading screens, arguing they provide a necessary transition and enhance world-building. Colantonio reflected on the challenges of revisiting the game after 14 years. The stream revealed a discarded plot point where Daud was meant to sever Corvo's hand, which would have added depth to the narrative. This concept later influenced Dishonored 2. The team has four more levels to explore in their playthrough, with fans hoping for discussions on the Knife of Dunwall and Brigmore Witches expansions.

Sony pulling back from PC also means it’s pulling back from China

Sony has shifted away from porting singleplayer PlayStation titles to PC, raising concerns about competition with Valve. Alinea Insights reported that 42% of Death Stranding 2's PC sales came from China, its largest market on Steam. Approximately 39.48% of Steam users have their language set to English, while 21.85% prefer Simplified Chinese, representing over 30 million players. Shift Up, developer of Stellar Blade, announced they will not partner with Sony for the sequel, focusing on a global market strategy. Alinea's analysis shows that releasing games on PC does not harm PlayStation sales; Death Stranding 2 saw increased PS sales following its PC launch, and Stellar Blade also experienced a rise in PS5 sales despite not being discounted. Launching games on PC broadens the player base and enhances marketing opportunities.
