Recover GhostLocker ransomware files

If you have been affected by GhostLocker ransomware, it is essential to act immediately to recover your files.

Ransomware has become a critical threat to companies of all sizes and industries due to the significant increase in attacks in recent years. Studies indicate that in over 70% of cases, data is completely encrypted, leading about 56% of victims to pay criminals the ransom. Fortunately, there are effective technical alternatives to recover data without making any payment to attackers.

GhostLocker ransomware is an advanced form of malware specifically designed to encrypt essential files on business and personal systems, making them completely inaccessible to their owners. This ransomware has become widely known for its ability to cause significant disruptions to critical operations, particularly affecting sectors such as healthcare, manufacturing, education, and finance.

While common viruses generally aim to cause general damage, GhostLocker ransomware is executed by specialized hackers who use advanced encryption techniques, such as AES-256 or RSA, to permanently block access to information, releasing it only upon possession of the specific key under the criminals’ control.

Additionally, hackers often apply the double extortion method, encrypting files while simultaneously stealing sensitive data, and threatening to publish it online to increase pressure for ransom payment.

Ransomware attacks have shown accelerated growth, increasing approximately 5% in the past year alone, with the average ransom demanded by criminals reaching millions of dollars. Many organizations, due to lack of effective recovery methods, end up yielding to the demands and funding further attacks.

We provide specialized solutions for the secure recovery of ransomware-encrypted files.

Answers from our experts

How does the GhostLocker ransomware attack work?

The GhostLocker ransomware attack typically occurs in several well-defined stages:

  • Silent infiltration: The attack starts with phishing techniques, where malicious emails or infected attachments are sent to victims. Another common method involves exploiting technical vulnerabilities in outdated systems, such as software breaches or insecure remote access (RDP).
  • Backup mapping and neutralization: Once inside the network, the ransomware carefully analyzes the environment, detecting important files and connected or online backups. The goal is to directly affect these backups, removing the possibility of quickly restoring the information.
  • Mass encryption of files: Once data is mapped, ransomware quickly starts encryption. Critical files, databases, enterprise resource planning (ERP) systems, virtual machines, and RAID systems are typically affected, making the files completely inaccessible.
  • Financial extortion: Upon completion of file encryption, criminals typically leave a ransom note demanding payment. Generally, instructions guide victims to communicate through secure channels or the dark web, specifying cryptocurrency payments to hinder financial tracking.

How much does it cost to decrypt GhostLocker ransomware?

Determining the precise cost of recovering files affected by GhostLocker ransomware directly depends on the scope and technical complexity of the incident.

The final value largely depends on elements such as the extent of compromised data, the specific types of systems involved (servers, virtual machines, storages, or databases), and the current state of existing backups.

To immediately initiate the process and receive a detailed proposal, contact our specialized team and request an initial diagnosis. Speak with one of our experts.

How long does the data recovery take?

The timeline for data recovery varies according to the specific circumstances of each attack. Generally, the process can range from a few days to several weeks, mainly depending on the volume of affected files, the extent of the impacted infrastructure, the complexity of the ransomware involved, and the condition of available backups.

After our initial diagnosis, performed within the first 24 business hours after your contact, our team will provide a clear and personalized estimate of the time required to successfully complete the process.

Is there any guarantee for data recovery?

Considering the technical complexity of ransomware attacks, no responsible company can guarantee in advance the complete recovery of files. Each incident presents unique technical aspects, such as different cryptographic algorithms and specific methods employed by criminals.

Nonetheless, Digital Recovery has specialized and exclusive technologies, such as the proprietary TRACER solution, achieving a high rate of success in recovering files encrypted by ransomware.

What you need to know

Preventing a GhostLocker ransomware attack requires a comprehensive cybersecurity framework, but that’s not all, let’s list some important points that you need to pay attention to.

  • Organization – Having documentation of the IT park helps a lot in the prevention process, in addition to the inventory of networks and computers. Develop rules so that new employees have clear company policy on the installation and use of programs on computers.
  • Strong Passwords – Passwords should be strong, containing more than 8 digits, including special ones. And do not use a single password for multiple credentials.
  • Security Solutions – Have a good antivirus installed, keep all programs up to date, especially the operating system. Besides the antivirus solution, you need a Firewall and endpoints. They will make sure that the system stays protected.
  • Beware of suspicious emails – One of the most used means for invasion used by hacker groups are spam email campaigns, so it is vital to create a security and awareness policy for employees not to download attached files sent by unknown emails.
  • Efficient backup policies – Backups are essential for any eventual incident, but even with this essential role many companies neglect it or create a backup schedule that is not effective. We have already assisted several clients that not only the data was encrypted, but also the backups. It is not recommended to keep online backups only. The best backup structure is 3x2x1, which is 3 backups, 2 online and 1 offline, in addition to creating a consistent routine of updating the backups.
  • Beware of unofficial programs – There are numerous paid programs that are made available for free on the Internet, such as Windows, Office and many others. They may appear to be free at first, but in the future can be used as a gateway for future hacker attacks. Even if official programs demand financial resources, they are a good investment and are also secure.

There are several strategies employed by GhostLocker criminals, the main ones are: downloads of infected files, malicious links, attacks via RDP, Phishing, spam email campaigns, and more. 

All of them have the same intention, to access the victim’s system without the victim’s awareness. To do so, the GhostLocker ransomware camouflages itself in the system so as not to be detected by defense systems. 

In the tactics that depend on the action of a user, phishing tactics are applied so that the victim, without realizing it, downloads the ransomware into the system.

High consumption of processing, memory and disk access are suspicious behaviors that need to be investigated thoroughly in order to assess whether an attack is underway.  

The GhostLocker ransomware uses the machine’s own resources to perform exfiltration. In order to encrypt the machine this demands the use of its own resources.

It is also possible to detect the GhostLocker attack by the changes made to the file extensions, this type of detection is a bit more complex because the encryption process will have already been started.

The data will remain encrypted, it will be necessary for the affected machine to be formatted. By doing this all stored data will be lost.

But in cases where the attacking group uses the double extortion tactic of copying and extracting all files and encrypting the original data, the stolen files will be posted on the group’s website or Dark Web forums and all original data will remain encrypted on the affected device, requiring the device to be formatted.
