Best Ransomware Protection 2026: Tested and Ranked

Ransomware protection is best approached as a layered strategy rather than relying on a single solution. The effectiveness of software is significantly enhanced by maintaining a well-managed backup that is disconnected during an attack. Five tools were evaluated based on their default settings, focusing on behavioral detection, protected folders, file rollback, and real-time protection. 1. Norton 360: Rated as the best overall ransomware protection, it offers comprehensive features including behavioral monitoring, protected folders with dual alert modes, and 50 GB of cloud backup within a single subscription. It has a perfect score in advanced threat assessments. 2. Bitdefender: Recognized for its file rollback and remediation capabilities, it provides an effective "undo" feature that restores files, although this feature is turned off by default. 3. Avast One Free: The best free ransomware protection option, it includes a dedicated shield on the free Windows tier and has achieved a perfect score in advanced threat assessments. 4. NordVPN Threat Protection Pro: Best for blocking the delivery route of ransomware, it prevents downloads before encryption starts but cannot stop the process once it has begun. 5. McAfee: Best for protecting multiple devices simultaneously, it offers unlimited device coverage on most plans with integrated ransomware defense in its scanning engine. Modern ransomware protection software has shifted from signature matching to focusing on monitoring the behavior of processes interacting with files. The four essential layers of protection include behavioral monitoring, protected folders, automatic file rollback, and backup. Most users do not need a separate anti-ransomware product, as these features are typically included in main antivirus suites, with the key consideration being whether these features are activated. The rankings of the tools were based on whether the ransomware protection layer is enabled by default, the extent of file recovery when intervention occurs, and the frequency of false positives during normal use. - Norton 360: Best overall, with protection enabled by default and a perfect score in advanced threat testing. - Bitdefender: Best for file rollback, but the rollback feature is disabled by default. - Avast One Free: Best free option, with a perfect score in advanced threat assessments but lacks rollback capabilities. - NordVPN Threat Protection Pro: Effective at blocking malware downloads but does not provide rollback or backup features. - McAfee: Suitable for families with multiple devices, offering automatic backup of flagged files but lacks user-configurable protected folder options. The effectiveness of ransomware protection tools is primarily assessed through behavioral responses rather than library matching. Backup remains a critical layer of defense, functioning even when other layers fail.

Automated PII redaction for Amazon RDS for PostgreSQL audit logs

The article discusses a serverless pipeline for creating an irreversibly redacted and queryable archive of Amazon RDS for PostgreSQL audit logs. It sanitizes sensitive information, such as Social Security numbers, credit card details, and email addresses, before storing the clean logs in Amazon S3, which can be queried using Amazon Athena. The deployment process is facilitated by a single AWS CloudFormation template. The challenge is that pgAudit logs sensitive data in cleartext to Amazon CloudWatch Logs, which poses compliance risks under regulations like GDPR and HIPAA. While CloudWatch Logs Data Protection offers reversible masking of PII, this is insufficient for compliance needs requiring permanent separation of PII from audit evidence. The proposed pipeline creates an irreversibly redacted copy stored in Amazon S3, ensuring original values cannot be restored. The deployment requires an active AWS account with specific permissions, AWS CLI v2, a compatible AWS region, and confirmation of service quotas. The CloudFormation template has four main parameters for deployment, including ProjectName, DBInstanceClass, DBAllocatedStorage, and EnvironmentType, with sensible defaults provided. Three deployment options are available: via the AWS console, AWS CLI, or a deploy script. After deployment, users can generate test data, trigger the redaction pipeline, and verify results in Athena. The process includes steps to create a PostgreSQL table, insert records with PII, run queries, and monitor the execution of the redaction pipeline. The article emphasizes that unredacted PII remains in the source CloudWatch Logs, recommending enabling CloudWatch Logs Data Protection for added security. To clean up resources and avoid charges, users must empty the S3 buckets and delete the stack. Cost considerations for the pipeline include infrastructure costs and the expense of achieving irreversibility.

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.

Active Exploitation Alert: Fake Bahrain Alert App Deploys Advanced Android Surveillance Malware Targeting Gulf Region Users

A cyber-espionage campaign has been identified involving a counterfeit Bahrain Alert Android application designed to surveil individuals in Bahrain and the Gulf region. The app masquerades as an official civil defense tool and employs social engineering tactics to compromise Android devices, extract sensitive data, and maintain remote access. It targets high-value individuals such as activists and journalists, particularly during civil unrest and missile alerts, leveraging trusted government branding to increase infection rates. The malware features a complex, multi-stage architecture with advanced evasion techniques and is distributed through phishing links and malicious websites. It initiates a four-stage infection process, ultimately installing a remote access trojan (RAT) that enables covert surveillance and encrypted communications. The malware can monitor device activity, capture credentials, and intercept communications, while also employing mechanisms to avoid detection and maintain persistence. The campaign primarily targets Bahraini citizens, exploiting fear during crises to encourage app installation. Although there are indications of Russian-speaking developers involved, there is no definitive attribution to a specific nation-state or APT group. Mitigation strategies include monitoring for suspicious app installations, user education on verifying app authenticity, and blocking known malicious domains.

Simplify AI agent orchestration with Lakebase Postgres

The auditing process has traditionally been labor-intensive, requiring extensive document reviews. CLA (CliftonLarsonAllen LLP) partnered with the Databricks Forward Deployed Engineering team to develop a document processing application that reduces extraction time from hours to minutes while maintaining quality. The application is built on the Databricks platform, utilizing technologies like Lakebase Postgres, Databricks Apps, Lakeflow Jobs, MLflow, and Unity Catalog Volumes. The application addresses challenges in document parsing, including unpredictable per-task latency, rate-limit-aware throttling, workload prioritization, cost attribution per task, and real-time progress visibility. It eliminates the need for multiple specialized systems by integrating components such as a web application for user interaction, Lakebase for state management, an orchestrator for task management, and AI agents for document processing. The task queue is supported by two Postgres tables in Lakebase, tracking task status and execution attempts. Concurrency safety is ensured through a locking mechanism, and crash recovery is facilitated by lease-based locking. The orchestrator implements rate-limit-aware throttling and idempotent webhook callbacks to manage task processing effectively. An operator dashboard provides real-time metrics on task status, agent performance, and workload costs, with live updates through Postgres LISTEN/NOTIFY events. Cost attribution is managed at the application level, allowing for detailed monitoring of expenditures. Lakebase enhances the orchestration process with features like autoscaling compute, OAuth-rotated authentication, Unity Catalog integration, and support for branching and snapshots.

Advanced Threat Protection: How AI Transforms Enterprise Security

An attacker is testing stolen passwords against a company with inadequate firewall protection, highlighting the flaws in traditional security measures. Modern attacks, including ransomware and phishing, have evolved, necessitating advanced threat protection (ATP) that incorporates artificial intelligence (AI) for improved threat detection and response. AI-driven ATP identifies attacks that conventional tools miss, such as fileless malware and targeted phishing, by learning normal operating patterns and flagging deviations. Traditional security relies on known malware signatures, which are ineffective against zero-day attacks and polymorphic malware that changes its identity. Cloud misconfigurations and hybrid security gaps further complicate security. AI enhances detection by focusing on malicious behaviors rather than just file signatures, allowing for rapid identification of threats. Automated incident response can isolate affected endpoints and terminate malicious processes quickly. Behavioral analytics and threat intelligence integration improve ATP effectiveness by understanding user behavior and recognizing attack patterns. AI-powered ATP significantly reduces breach containment time and false positives, shifting the focus from reactive cleanup to proactive prevention. Best practices for maximizing ATP include integrating it into existing security operations, keeping machine learning models updated, and regularly testing defenses against real-world threats.

Advanced Threat Protection: How AI Transforms Enterprise Security

An attacker is testing stolen passwords against a company that incorrectly believes its firewall is sufficient protection. Traditional defenses have become inadequate due to the speed and sophistication of modern attacks, including ransomware groups renting tools and phishing kits being easily accessible. Advanced threat protection (ATP) was designed to address these challenges, especially with the integration of artificial intelligence (AI). AI-powered ATP identifies attacks that conventional tools overlook, such as fileless malware and targeted phishing attempts, by learning the normal behavior of an organization’s environment and flagging anomalies. Traditional security relies on identifying known malware through established fingerprints, which fails against novel threats like zero-day attacks and polymorphic malware. The rise of remote work and cloud services has introduced new risks due to misconfigurations and inconsistent security rules. AI enhances threat detection by focusing on malicious behavior rather than matching files against known threats, allowing for rapid detection and automated incident response. Behavioral analytics establishes a baseline for users and devices, flagging deviations that may indicate insider threats or credential theft. Integrating threat intelligence provides insights into emerging threats and helps prioritize alerts. AI-driven ATP can contain breaches faster, significantly reducing the financial impact and dwell time of attackers. Best practices for maximizing ATP include integrating with security operations, ensuring comprehensive coverage, updating models regularly, conducting real-world testing, securing AI systems, and maintaining human oversight.
