Dirty App Removal: HLAS Ransomware

Hlas is a form of ransomware from the infamous Djvu family. Once it infects your computer, it encrypts your files and adds the “.hlas” extension to them. For example, a file originally named “1.jpg” will be renamed “1.jpg.hlas.” In addition to this, the ransomware creates a ransom note called “_readme.txt,” which instructs the victim on how to decrypt their files by paying a ransom.

Djvu ransomware, including the Hlas variant, is often bundled with other dangerous malware such as information stealers like RedLine and Vidar, making it even more dangerous.

What to Expect with the Hlas Ransom Note

In the ransom note, the attackers explain that your files—such as pictures, databases, and documents—have been encrypted with strong encryption algorithms. To get the decryption tool and unique key required to restore your files, they demand a payment of $999. However, they offer a 50% discount if contacted within 72 hours, lowering the price to $490.

As a gesture of “good faith,” the criminals offer to decrypt one file for free, provided it doesn’t contain any valuable data. Victims are directed to contact the attackers through various email address that victimized computer users should avoid at all costs.

The Mechanics of Hlas Ransomware

Hlas ransomware employs a series of advanced tactics to encrypt your files and evade detection. One of its key methods is the use of process hollowing, where the ransomware disguises itself as a legitimate process. Additionally, it resolves APIs dynamically and loads malicious libraries like msim32.dll to further hide its actions.

These techniques make it challenging to detect and remove Hlas ransomware manually, reinforcing the need for advanced anti-malware tools.

How Does Hlas Infect Your Computer?

Hlas ransomware can infiltrate your system in various ways:

• Pirated Software and Cracking Tools: One of the most common delivery methods is through illegal downloads of software or key generators.
• Email Attachments: Cybercriminals often send harmful attachments or links in phishing emails that appear legitimate.
• Exploiting Vulnerabilities: Outdated operating systems and software can provide an entry point for ransomware.
• Malicious Ads and Websites: Fake ads or deceptive websites can also spread ransomware, especially when using peer-to-peer (P2P) networks or third-party downloaders.

How to Remove Hlas Ransomware Safely

If your system is infected with Hlas ransomware, immediate action is critical. Follow these steps to remove the threat:

1. Disconnect from the Internet: This can prevent the ransomware from communicating with its command-and-control servers.
2. Use a Trusted Anti-Malware Program: We recommend using SpyHunter or another reliable anti-malware tool to automatically detect and eliminate the ransomware.
3. Avoid Paying the Ransom: There’s no guarantee that paying the attackers will result in the decryption of your files. In many cases, victims are left with no decryption key even after payment.

Protecting Yourself From Ransomware Infections

Prevention is always better than cure when it comes to ransomware. Here are some best practices to avoid getting infected:

• Download Only from Official Sources: Stick to legitimate websites and app stores for downloading software.
• Beware of Phishing Emails: Don’t open unexpected email attachments or click on suspicious links, especially from unknown senders.
• Keep Software Updated: Ensure your operating system and software are regularly updated to close any security vulnerabilities.
• Use Anti-Malware Software: Regularly scan your system with trusted security tools like SpyHunter to detect and remove malware before it causes damage.
