Recover Netwalker ransomware files

If you have been affected by Netwalker 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. Netwalker 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.

Unlike traditional viruses, Netwalker ransomware is controlled by specialized criminal groups that use advanced encryption algorithms, such as AES-256 or RSA, to lock access to data, with the unique key kept exclusively by the attackers.
In addition, the practice known as double extortion is common, wherein besides encrypting files, hackers steal copies of sensitive data to threaten victims with public exposure.

Ransomware attacks have intensified significantly, registering an estimated increase of 5% in the last year alone. Ransom demands easily reach millions of dollars, and numerous companies, unaware of alternative solutions, end up paying, further strengthening criminal actions.

Answers from our experts

How does the Netwalker ransomware attack work?

Attacks caused by Netwalker ransomware typically follow clear and detailed stages:

  • Silent infiltration: Initially, the ransomware infiltrates through phishing campaigns, sending fraudulent emails or malicious attachments to victims. Another common approach involves exploiting existing technical vulnerabilities in outdated systems, such as software security flaws or unsecured remote connections (RDP).
  • Backup mapping and neutralization: After initial infiltration, the ransomware performs detailed mapping of the internal network, targeting strategic files and available or online-connected backups, aiming to neutralize these backups to prevent rapid recovery.
  • Mass encryption of files: Right after identifying strategic data, ransomware rapidly encrypts the information. Typically, essential files like databases, ERP systems, virtual machines, and RAID systems are affected, making information access impossible.
  • Financial extortion: Immediately after data encryption, hackers leave a note demanding ransom payment. Typically, the instructions include communication through secure platforms or dark web sites, requesting cryptocurrency payments to prevent tracing.

How much does it cost to decrypt Netwalker ransomware?

The exact value to decrypt files impacted by Netwalker ransomware is defined according to the extent and level of technical complexity of the suffered attack. Typically, the cost is directly influenced by factors such as the volume of data affected, the type of system impacted (servers, storages, virtual machines, or databases), and the availability of intact backups. If you want to quickly start recovery and obtain an accurate quote, contact our specialized team to perform a detailed initial diagnosis. Talk to our specialists now.

How long does the data recovery take?

The period required to restore files can vary significantly depending on the specifics of the attack. Usually, the process takes from a few days to a few weeks, with the exact time influenced by factors like the amount of encrypted data, the complexity of the attack, the size of the affected network, and the quality of existing backups. After receiving your contact, we perform an initial diagnosis within 24 business hours, and then our team will inform you of a clear and personalized estimate of the timeframe required to complete your data recovery.

Is there any guarantee for data recovery?

Because of the unique technical characteristics of each ransomware attack, it is impossible to guarantee 100% success in data recovery in advance. Each case has its own particularities, such as different encryption algorithms and diverse techniques used by attackers. Nevertheless, Digital Recovery relies on proprietary and advanced technologies, including the exclusive TRACER solution, capable of providing high success rates in recovering ransomware-encrypted files.

What you need to know

How to prevent a Netwalker ransomware attack?

Preventing a Netwalker 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 Netwalker 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 Netwalker 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 Netwalker 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 Netwalker 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.
