Migrate self-managed PostgreSQL to Amazon RDS using the RDS console

Running PostgreSQL on Amazon EC2 requires users to manage operational tasks such as patching, backups, and security. Migrating to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition offers a fully managed service that automates these tasks, allowing development teams to focus on application development. The migration process uses the auto-migration feature in the Amazon RDS console, supported by AWS Database Migration Service (AWS DMS), which facilitates PostgreSQL-to-PostgreSQL migrations using native tools for accurate schema mapping and faster migration. The migration can be executed using various methods, including pg_dump/pg_restore, manual AWS DMS tasks, or third-party tools, with the RDS console approach being preferred for its reliability and minimal setup effort. AWS DMS supports three replication modes: full load, CDC only, and full load + CDC, with the migration duration depending on database size and network throughput. Prerequisites for migration include having a source PostgreSQL 10.4+ on Amazon EC2, a target RDS for PostgreSQL or Aurora PostgreSQL, proper IAM roles, stored credentials in Secrets Manager, and appropriate networking configurations. Considerations include unsupported objects, potential issues with sequence values, and the need to avoid schema changes during CDC. The migration involves preparing the source database, creating necessary users and permissions, and executing the migration through the RDS console. Post-migration, it is essential to verify data integrity, optimize performance by updating statistics and rebuilding indexes, and implement security best practices such as disabling the DMS user and enforcing SSL/TLS connections. Common troubleshooting errors during migration include permission issues, incorrect WAL levels, and connection refusals, each with specific resolutions. Finally, to avoid ongoing charges, it is recommended to clean up resources created during the migration process, including deleting the DMS migration task, logical replication publications, Secrets Manager secrets, and the target RDS/Aurora instance.

Your Windows Recycle Bin is a privacy risk—here’s how to actually delete your files

The Recycle Bin in Windows, introduced in 1995, serves as a temporary storage for deleted files rather than permanently removing them. When a file is deleted, it is moved to the Recycle Bin, which requires manual emptying or activation of a Storage Sense policy to clear its contents. This can lead to reduced hard drive space for users unaware of its behavior. The Recycle Bin can contain sensitive information, and if someone gains access to a Microsoft account, they can view its contents. Even after emptying the Recycle Bin, data can be recovered unless overwritten, with different recovery processes for solid-state drives (SSDs) due to maintenance routines like the TRIM command. Risks extend beyond physical access, as compromised accounts or malware can access deleted files. To securely delete sensitive files, users can use the Shift + Del shortcut, file shredding applications, and consider encrypting their drives with BitLocker. Specialized shredders for SSDs exist, and users can optimize drives through Windows settings to manage data recovery risks.

How I stopped being my parents’ emergency IT hotline — The complete list of Windows Security settings I made them fix once and for all

A family member inquired about the necessity of a password manager, reflecting growing cybersecurity concerns. A parent received a suspicious "tech support" message, indicating potential security risks. Windows Hello allows users to log in with a PIN, fingerprint, or facial recognition on Windows 11 PCs. Users can set it up via Settings > Accounts > Sign-in options. Regular updates through Windows Update are essential for security, and users can check their status in Settings > Windows Update. Windows Defender is the built-in antivirus for Windows 11, typically enabled by default, but users should verify its status in Settings > Privacy & security > Windows Security > Virus & threat protection. The 'Find My Device' feature can be enabled in Settings > Privacy & security > Find my device to track and lock a lost or stolen laptop. Switching from a local account to a Microsoft account with two-factor authentication (2FA) enhances security, accessible via Settings > Accounts > Your info. Device encryption can protect sensitive data, available in Settings > Privacy & security > Device encryption for Home versions and BitLocker for Pro versions. Using a Standard account instead of an Administrator account reduces malware risks, managed through Settings > Accounts > Family. Password managers like NordPass, 1Password, and Bitwarden help generate strong, unique passwords for accounts. Users should learn to spot phishing scams, be cautious of unsolicited tech support calls, and avoid installing software suggested by unknown callers to maintain cybersecurity.

Microsoft is using TPM chips to crack down on pirated Windows activations

Microsoft has mandated the inclusion of the Trusted Platform Module (TPM) as a standard feature in all new motherboards and CPUs to enhance the Windows activation process. The company has introduced an enhancement to its Key Management Service (KMS) that leverages TPM's security capabilities to authenticate the legitimacy of KMS servers. This new "TPM-based attestation" aims to mitigate exploitation risks associated with KMS by validating the cryptographic integrity of KMS servers. Starting in August 2026, TPM-based attestation will be required for KMS activation with the next release of Windows Server. Microsoft has also closed off the "KMS38" activation method in 2025, while traditional KMS activation remains functional. The Massgrave collective has developed an Online KMS method that may be impacted by the new TPM-based attestation.

Amid youth protests, Centre directs blocking of messaging app that works without internet: Developer

The Union Home Ministry has requested GitHub to remove repositories related to Bitchat, a Bluetooth-based messaging app that functions without internet connectivity, due to security concerns amid protests in central Delhi. Jack Dorsey, co-founder of Twitter, shared the directive, which aims to suppress the availability of such technologies. The Indian Cybercrime Coordination Centre has expressed worries that decentralized communication tools like Bitchat could be misused for unlawful activities. The directive, issued under Section 79(3)(b) of the Information Technology Act, 2000, requires GitHub to disable access to three Bitchat-related repositories within three hours. The Internet Freedom Foundation criticized the government's lack of transparency and argued that concerns about potential misuse do not justify banning access to the app's code. The protests, initiated by the Cockroach Janta Party, are demanding the resignation of Union Education Minister Dharmendra Pradhan over alleged mismanagement of competitive examinations, with increased support following police actions against demonstrators.

CrashStealer Mac malware steals passwords and wallets

A sophisticated new malware targeting Mac users, named CrashStealer, has been discovered by security researchers at Jamf Threat Labs. It masquerades as Apple's legitimate crash-reporting software and was first identified in May 2026, with active attacks detected by early July. CrashStealer is designed to extract sensitive information, including browser credentials, password manager data, and cryptocurrency wallet information, and can copy the Mac login Keychain. It uses native C++ programming, encrypts collected files, and employs anti-debugging features. The malware is distributed through a disk image labeled "Werkbit Setup," which features a polished installer that bypasses Mac security warnings by using a valid Apple Developer ID and notarization ticket. Once opened, it connects to GitHub for commands and downloads a script that installs a second disk image named CrashReporter.dmg, which mimics an Apple system component. CrashStealer presents a fake password prompt resembling a legitimate macOS request, verifying entered passwords locally. It targets data linked to various browsers and password managers, scanning for approximately 80 cryptocurrency wallet extensions and 14 password managers. Stolen data is stored in hidden folders, encrypted using AES-256-GCM, and packaged into hidden ZIP archives before being uploaded. Warning signs of infection include a website requiring a meeting PIN for download, unexpected password prompts, and unfamiliar apps requesting Full Disk Access. Users are advised to download apps from verified sources, avoid overriding security warnings, pause before entering passwords, review app permissions, install security updates, use antivirus software, and act quickly if they installed Werkbit Setup.
