Bitdefender offers a free, universal decryption tool for victims of the devastating REvil (also known as Sodinokibi) ransomware. Developed in collaboration with a trusted, international law enforcement partner, this master decryptor allows individuals and organizations to safely restore their encrypted files without paying millions of dollars to cybercriminals.

If your business or personal devices were compromised by REvil, you can download the tool immediately to reclaim your digital assets. What is REvil Ransomware?

REvil operates under a Ransomware-as-a-Service (RaaS) model and stands as one of the most prolific cybercrime operations in history. The group gained global notoriety by targeting high-profile technology providers, managed service providers (MSPs), and retailers, demanding massive extortion payments reaching up to $70 million.

REvil employs a “double extortion” tactic. They do not just encrypt local system data; they also steal confidential information and threaten to publish it on the dark web if the victim refuses to pay. Tool Compatibility and Scope

Before deploying the utility, verify if your data fits the criteria for recovery:

The Target Window: The Bitdefender REvil Decryptor is a universal master tool that successfully unlocks files encrypted by REvil prior to July 13, 2021.

The Core Mechanism: The tool leverages master keys obtained via law enforcement operations to bypass the ransomware’s cryptographic lock.

Limitations: Some specialized or altered strains deployed after the threat group’s infrastructure reemerged may not be fully decryptable with this specific version. Step-by-Step Decryption Guide

Why UDPRun is Changing Low-Latency Data Delivery UDPRun is fundamentally reshaping low-latency data delivery by resolving the historic compromise between networking speed and data reliability. For decades, developers and network engineers operating in high-stakes environments had to choose between two transport pillars: the Transmission Control Protocol (TCP), which ensures error-free, orderly delivery at the cost of high latency, or the User Datagram Protocol (UDP), which strips away handshakes and acknowledgments for rapid, “fire-and-forget” data streams.

By eliminating the structural bottlenecks traditional architectures face, UDPRun delivers sub-millisecond, highly resilient throughput tailored for modern, real-time industrial ecosystems. The Architecture Behind UDPRun

Traditional network optimization frequently focuses on raw bandwidth, yet bandwidth cannot offset poor systemic latency. In a standard UDP environment, the application layer remains vulnerable to packet loss, out-of-order delivery, and severe operating system scheduling jitter. UDPRun changes this dynamic through several core technological architectural shifts:

The Ultimate Guide to Using a Password Generator Safely Using a password generator is the single best way to protect your online accounts from hackers. Humans are notoriously bad at creating random passwords, often falling back on predictable patterns like birthdays, pet names, or sequential numbers. A password generator eliminates human bias by using mathematical algorithms to create completely random, unguessable strings of characters.

However, generating a strong password is only half the battle. If you generate a flawless password but handle it incorrectly, your accounts remain vulnerable. To ensure your digital security, you must understand how to use these tools without compromising your data. How Password Generators Work

Password generators use algorithms called Pseudorandom Number Generators (PRNGs) or Cryptographically Secure Pseudorandom Number Generators (CSPRNGs).

PRNGs use mathematical formulas to produce sequences of numbers that appear random. While sufficient for casual use, they can theoretically be predicted if a hacker determines the starting seed value.

CSPRNGs draw randomness from physical sources within your computer, such as unpredictable thermal noise or precise mouse movements. This makes the resulting passwords completely impossible for malicious software to anticipate.

When you click “generate,” the software uses this randomness to select characters from a pool of uppercase letters, lowercase letters, numbers, and symbols based on your custom criteria. The Risks of Online Generators

Many people use free, web-based password generators found through search engines. While convenient, web-based generators introduce distinct security vulnerabilities.

If a website does not use local JavaScript to create the password on your device, your new password is created on a remote server. This means the password must travel across the internet to reach your screen, creating an opportunity for interception. Additionally, malicious or compromised websites can quietly log every password they generate and tie them to your IP address.

There is also the threat of browser extensions and malware. If your device is infected with spyware or a malicious browser extension, it can read the text on your screen or copy your clipboard data the moment the website displays your new password. Best Practices for Secure Generation

To maximize your security, follow these essential rules when creating new credentials:

Use Local Generation: Choose tools that generate passwords locally on your device using client-side code, meaning the data never travels over the internet.

Aim for Length: Aim for a minimum of 16 characters. Length is the most critical factor in resisting brute-force attacks.

Include All Character Types: Check the boxes for uppercase letters, lowercase letters, numbers, and special symbols to maximize complexity.

Avoid Predictable Patterns: Never use generators that create “readable” or pronounceable passwords, as these significantly reduce entropy.

Turn Off Clipboard History: Disable cloud-syncing clipboard features on your operating system so your copied passwords are not stored in a history log. Where to Safely Generate Passwords

The safest place to generate a password is inside a dedicated, reputable password manager. Applications like Bitwarden, 1Password, and KeePass feature built-in, open-source CSPRNGs.

Because these tools generate the password directly inside the encrypted vault where it will be stored, the plaintext password is never exposed to the open internet or the system clipboard. Most modern web browsers, including Chrome, Safari, and Firefox, also feature safe, built-in password generators that automatically link and save credentials to your localized account. Securing Your Generated Passwords

A secure password is useless if it is stored unsafely. Never save your generated passwords in text documents, spreadsheet files, or digital sticky notes on your desktop. These formats lack encryption and are the first targets for data-stealing malware.

Instead, rely on a dedicated password manager protected by a strong master password and two-factor authentication (2FA). By pairing randomly generated passwords with a secure storage vault, you create a robust defense system that keeps your digital identity safe from modern cyber threats.

5 Easy Ways to Automate VB.NET Backups Data loss can devastate any application. Implementing an automated backup system ensures your user data, logs, and configuration files remain safe without requiring manual intervention. Because VB.NET integrates seamlessly with the .NET ecosystem and the Windows operating system, developers have access to several straightforward approaches for automation.

Here are five easy ways to automate your backup processes using VB.NET. 1. The Built-in FileSystem Integration

The simplest way to create a backup is by using the native My.Computer.FileSystem or System.IO namespaces. You can write a short VB.NET method that copies files or entire directories from a source path to a secure backup directory.

Imports System.IO Public Sub CopyDirectoryBackup(sourceDir As String, destDir As String) Try If Directory.Exists(sourceDir) Then ‘ Create destination with a timestamped folder Dim timestamp As String = DateTime.Now.ToString(“yyyyMMddHHmmss”) Dim finalDest As String = Path.Combine(destDir, “Backup” & timestamp) My.Computer.FileSystem.CopyDirectory(sourceDir, finalDest, True) Console.WriteLine(“Backup completed successfully.”) End If Catch ex As Exception Console.WriteLine(“Backup failed: ” & ex.Message) End Try End Sub Use code with caution.

To automate this, run the compiled executable using the Windows Task Scheduler. This offloads the timing logic to the operating system, allowing you to trigger the VB.NET console app daily, weekly, or upon system idle. 2. Compressing Backups with System.IO.Compression

Raw file copies consume massive amounts of storage over time. VB.NET makes it incredibly easy to compress your backup folders into standard .zip files using the ZipFile class. This saves disk space and makes the backups easier to transfer over a network.

Ensure you reference System.IO.Compression.FileSystem in your project, then use the following logic:

Imports System.IO.Compression Public Sub CreateZipBackup(sourceDir As String, zipPath As String) Dim timestamp As String = DateTime.Now.ToString(“yyyyMMdd”) Dim finalZipName As String = Path.Combine(zipPath, $“Backup_{timestamp}.zip”) ’ Generate the compressed archive ZipFile.CreateFromDirectory(sourceDir, finalZipName) End Sub Use code with caution.

3. Utilizing a Background Worker or Timer for App-Level Automation

If you want your VB.NET desktop application (WinForms or WPF) to handle its own backups while it runs, using a standard loop will freeze the user interface. Instead, use a System.Timers.Timer or a BackgroundWorker to run the backup on a separate thread.

Set the timer interval (e.g., 86,400,000 milliseconds for 24 hours).

Handle the Elapsed event to trigger your backup code safely in the background.

This approach is ideal for local software, like point-of-sale systems, that need to back up data right before closing or at the end of a business shift. 4. Running SqlBackup Locally via ADO.NET

If your VB.NET application relies on a local or remote SQL Server database, backing up raw .mdf files while the database engine is running can cause corruption. Instead, use ADO.NET to programmatically execute a Transact-SQL (T-SQL) backup command.

Imports System.Data.SqlClient Public Sub AutomateSqlBackup() Dim connectionString As String = “Server=localhost;Database=YourDB;Trusted_Connection=True;” Dim query As String = “BACKUP DATABASE [YourDB] TO DISK = ‘C:\Backups\YourDB.bak’ WITH FORMAT, MEDIANAME = ‘SQLServerBackups’, NAME = ‘Full Backup of YourDB’;” Using conn As New SqlConnection(connectionString) Using cmd As New SqlCommand(query, conn) conn.Open() cmd.ExecuteNonQuery() End Using End Using End Sub Use code with caution.

Pairing this function with an application startup or shutdown event ensures you always have a fresh copy of the database. 5. Uploading Backups to Cloud Storage APIs

Local backups protect against user error, but they fail if the local hard drive crashes or suffers physical damage. True automation should include an offsite copy. You can use VB.NET to interact with modern cloud storage APIs like Amazon S3, Azure Blob Storage, or Google Cloud Storage.

By installing the respective SDK via NuGet (for example, AWSSDK.S3), you can write a routine that first zips your files locally, and then streams the file straight to a cloud bucket:

’ Conceptual snippet using AWS SDK Dim transferUtility As New Amazon.S3.Transfer.TransferUtility(s3Client) Await transferUtility.UploadAsync(“C:\Backups\Backup_2026.zip”, “my-secure-bucket”) Use code with caution.

Automating your VB.NET backups doesn’t require expensive third-party enterprise tools. By combining basic file operations, zip compression, SQL commands, and Windows Task Scheduler, you can build a reliable, set-and-forget data safety net tailored exactly to your application’s architecture. If you need help implementing these methods, let me know:

What type of data are you backing up? (Files, folders, or an SQL database?)

Where is the target backup location? (Local drive, network share, or cloud?) How frequently do the backups need to run?
