Blizzard doing ‘a thorough scrub’ of illegitimate World of Warcraft Mythic-Plus dungeon rankings, with more changes to come

Blizzard Entertainment is reviewing World of Warcraft Mythic Plus Dungeon rankings due to concerns over players purchasing carries, following the introduction of rewards for the top 1% during the Midnight expansion. Game director Ion Hazzikostas confirmed that the team is thoroughly examining this issue and will provide updates soon. The competitive rankings have led to discussions about the rapid increase in cutoff scores and the prevalence of paid invitations for +21 level groups. Players have faced penalties for obtaining Mythic raiding mounts through real-money transactions, causing confusion over legitimate practices. The percentage-based ranking system has increased participation in Mythic Plus dungeons but resulted in lower retention rates compared to the previous season. Community feedback on the new rewards has been mixed, with some players feeling stressed by the uncertainty of the cutoff. Class balance has also become a concern, as successful teams tend to favor specific "meta" specs, potentially limiting accessibility for other players. Blizzard aims to keep dungeons accessible for all classes while considering specialization-specific cutoffs for future seasons.

Fake dating apps are being used to target Android users: How the new cyber scam works

India's cybercrime authorities have warned about the misuse of dating and adult-themed advertisements on social media platforms like Instagram and Facebook, which are being exploited by criminals to distribute malicious Android applications. These ads redirect users to external websites where they are prompted to download APK files, bypassing security measures of trusted app stores. The Indian Cybercrime Coordination Centre (I4C) has identified several malicious applications, including Night Play, Reloop, Kyss, Vimo, Rivo, Nexo, and Vixa, and cautions against installing unfamiliar applications promoted through unsolicited ads. These apps may request sensitive permissions, such as access to SMS messages, contacts, photos, device storage, and Accessibility Services, which can allow fraudsters to access valuable information. Compromised devices can lead to financial fraud by intercepting OTPs and other verification details. The I4C recommends using trusted app stores, keeping Google Play Protect active, reviewing app permissions, and being cautious with social media ads. If a suspicious app is installed, users should restart their phone in Safe Mode to uninstall it, disable its permissions if necessary, and consider a factory reset if removal fails. Users who suspect fraud are encouraged to report incidents promptly.

Researchers find way to weaponize Windows Defender’s own driver

Check Point Research revealed a technique that uses the boot-time remediation driver BTR.sys, part of Windows Defender, to execute kernel-level operations on Windows systems from Windows 7 to Windows 11 25H2. This method does not exploit software vulnerabilities but leverages BTR.sys, which is designed to remove locked malware components. Researchers reverse-engineered its undocumented protocol, leading to the creation of a proof-of-concept tool, BTR_CLI, that can install the driver as a service without standard management protocols. Once operational, BTR.sys can delete or move files, modify registry entries, and remove security binaries, including parts of Defender, during a specific period when the file system is writable. To exploit this technique, an attacker needs administrator privileges, specifically SeLoadDriverPrivilege. Although Microsoft does not consider this a critical issue due to the requirement of pre-existing administrative access, it highlights a significant potential vulnerability. There have been no documented real-world attacks using this technique.

Migrate Amazon Aurora PostgreSQL across major versions with active Debezium CDC connectors using native logical replication

Organizations using Debezium Change Data Capture (CDC) connectors on Amazon Aurora PostgreSQL-Compatible Edition face challenges during major database version upgrades. In-place upgrades require downtime, while blue/green deployments disrupt CDC event pipelines. A method using PostgreSQL's native logical replication allows migration between a source cluster (current version) and a target cluster (new major version) without a full connector re-snapshot. This approach minimizes risks of data loss and allows existing Debezium connectors to operate on the source during synchronization. The cutover process involves disabling the replication subscription, synchronizing sequences, creating a new Debezium replication slot on the target, and redirecting the connector, resulting in a brief pause for Kafka consumers. Prerequisites for this method include enabling logical replication on the source cluster, ensuring the target cluster is provisioned in the same VPC, and confirming that tables participating in CDC have primary keys. The process involves configuring parameter groups, creating publications, and establishing subscriptions for logical replication. During cutover, application writes are halted, and replication lag must be monitored to ensure it reaches zero before proceeding. After the cutover, ongoing monitoring of replication health and Kafka consumer offsets is necessary. Common failure scenarios include Aurora writer failover, Debezium connector stalls, large messages exceeding Kafka limits, DDL changes during synchronization, and long-running transactions blocking lag drain. Each scenario has specific symptoms, detection methods, and resolutions. Post-migration, organizations should establish monitoring for replication lag growth and Kafka consumer offset divergence. Automation can streamline the migration process for organizations managing multiple clusters, utilizing AWS Cloud Development Kit (CDK) constructs for cluster provisioning, schema replication, and cutover orchestration. After verifying stable operation on the target cluster, the old Debezium connector and source cluster can be decommissioned. Limitations include the absence of failover slots on Aurora PostgreSQL 17 and the need to handle TOAST columns appropriately.
