What Is LucKY_Gh0$t Ransomware?

LucKY_Gh0$t is a type of ransomware, a malicious program designed to encrypt a victim's files, rendering them inaccessible until a ransom is paid. In this case, the ransomware is based on the Chaos ransomware, a well-known strain in the cybercriminal community. Once installed, LucKY_Gh0$t encrypts files on the victim’s system, renaming them with random extensions, which can make recovery difficult or impossible without the decryption key.

Upon completing the encryption process, LucKY_Gh0$t changes the victim's desktop wallpaper and drops a ransom note, "read_it.txt," which explains the situation and demands payment. Typically, the attackers demand payment in cryptocurrency (often Bitcoin), which makes tracking payments difficult. The ransom note also instructs the victim to contact the attackers through the Session messenger app, providing a unique decryption ID for the victim.

Symptoms of LucKY_Gh0$t Ransomware Infection

When a system is infected with LucKY_Gh0$t, victims experience the following symptoms:

• File Inaccessibility: Files stored on the computer cannot be opened, and attempting to do so will result in an error message.
• Renamed Files: The extension of each encrypted file is changed, often with four random characters added to the original extension. For example, a document like "1.jpg" might be renamed to "1.jpg.1pbx."
• Ransom Note Displayed: The ransomware drops a file named "read_it.txt" on the infected system, which contains the ransom message explaining that the victim’s files have been encrypted and how to pay for decryption.
• Modified Desktop Wallpaper: The desktop wallpaper is changed to inform the victim about the attack, increasing panic and pressure to pay the ransom.

Ransom Note Content

The ransom note delivered by LucKY_Gh0$t reads as follows:

How Did LucKY_Gh0$t Get On My Computer?

LucKY_Gh0$t is typically distributed through malicious means, including:

• Infected Email Attachments: Cybercriminals often send phishing emails with malicious attachments. These emails may look legitimate, but opening the attachment can trigger the ransomware download.
• Torrent Websites: Downloading pirated software or media from torrent websites can result in the installation of ransomware.
• Malicious Ads: Exploiting vulnerabilities in web browsers, malicious ads (malvertising) can lead to an automatic ransomware download.

How To Remove LucKY_Gh0$t Ransomware

Step 1: Disconnect From the Network

Immediately disconnect your computer from the internet and any local network. This prevents the ransomware from communicating with its command-and-control server and spreading to other devices.

Step 2: Boot Into Safe Mode

Reboot your computer in Safe Mode to prevent the ransomware from running when the system starts. Safe Mode limits the execution of non-essential processes, making it harder for the malware to operate.

Step 3: Use SpyHunter to Scan for and Remove LucKY_Gh0$t

SpyHunter is an effective tool for detecting and removing ransomware like LucKY_Gh0$t. Follow these steps:

1. Download and Install SpyHunter.
2. Run a Full System Scan: Open SpyHunter and run a full system scan to detect any malware, including LucKY_Gh0$t.
3. Remove Detected Threats: After the scan, SpyHunter will list any threats found. Select all items related to LucKY_Gh0$t and remove them.
4. Restart Your Computer: Once the malware has been removed, restart your system to ensure no remnants remain.

Step 4: Restore Files

If you have backups of your files, you can restore them now that the malware is removed. If you don’t have backups, unfortunately, you will need to rely on third-party decryption tools (if available) or contact a cybersecurity expert for further assistance.

Preventive Methods Against LucKY_Gh0$t Ransomware

To avoid future infections by LucKY_Gh0$t or similar ransomware, consider implementing the following preventive measures:

• Use Robust Anti-Malware Software: Install reputable anti-malware software like SpyHunter to detect and block ransomware before it can do damage.
• Regularly Backup Your Files: Maintain regular backups of your critical files, either via cloud storage or external drives, to ensure you can recover your data in case of a ransomware attack.
• Exercise Caution with Email Attachments: Never open attachments from unknown or untrusted sources. Verify email senders before clicking on links or downloading files.
• Update Your Software: Ensure that your operating system and all installed software are up to date with the latest security patches.
• Use Strong Network Security: Employ firewalls and secure your network to prevent ransomware from spreading across multiple devices.

Conclusion

LucKY_Gh0$t ransomware is a significant threat to both individuals and businesses, encrypting files and demanding ransom for their release. It is crucial to act quickly to contain the infection and avoid paying the ransom. Using SpyHunter to remove the ransomware and following preventive measures can safeguard your system against future attacks.
