Recover Qlocker ransomware files

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

Ransomware attacks have become one of the most dangerous digital threats, significantly increasing in recent years and impacting companies across all sectors and sizes. Recent studies show that over 70% of these attacks result in full data encryption, causing about 56% of victims to give in to criminals’ demands. Fortunately, there are effective solutions to recover files without negotiating with hackers. Qlocker ransomware represents a sophisticated threat designed to completely block access to important files, whether on corporate or personal devices, through robust encryption. Recently, this type of ransomware has gained attention due to its destructive impact, seriously affecting essential sectors such as healthcare, education, industry, and financial markets.

Unlike traditional viruses, Qlocker 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.
It is also quite common for ransomware to employdouble extortion strategies, where criminals copy important files before encrypting them, using the threat of public exposure of stolen data as an additional pressure tactic on victims.

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.

We have exclusive technologies for effective decryption and recovery of ransomware-affected data.

Answers from our experts

How does the Qlocker ransomware attack work?

Usually, the Qlocker ransomware attack occurs through specific and well-structured stages:

  • Silent infiltration: The attack usually begins through phishing, by sending malicious emails or infected files to victims. Additionally, technical vulnerabilities in outdated systems, such as breaches in old software or insecure remote access via RDP, are commonly exploited.
  • Backup mapping and neutralization: After the initial entry, the ransomware conducts an internal network reconnaissance, identifying strategic files and particularly connected or online backups. The aim is also to compromise these backups, eliminating quick recovery options.
  • Mass encryption of files: Following initial reconnaissance, ransomware immediately encrypts the identified files. Critical data, databases, ERPs, virtual machines, and RAID arrays are frequently compromised, completely blocking user access.
  • Financial extortion: After encrypting the data, criminals leave a ransom note demanding payment. Usually, instructions for communication through secure platforms or the dark web are provided, requiring payments in cryptocurrencies to hinder tracing.

How much does it cost to decrypt Qlocker ransomware?

Determining the precise cost of recovering files affected by Qlocker ransomware directly depends on the scope and technical complexity of the incident. 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. To expedite the process and obtain a precise and personalized assessment, we recommend contacting our specialists directly for an initial diagnosis. Request specialized support right away.

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 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?

Due to the technical nature of ransomware attacks, no responsible company can promise a 100% upfront guarantee of full data recovery. Each attack has its own technical peculiarities, such as different encryption algorithms and methods used 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.

How to prevent a Qlocker ransomware attack?

Preventing a Qlocker 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 Qlocker 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 Qlocker 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 Qlocker 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 Qlocker 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.

If a device is affected by Qlocker ransomware that uses encryption, the encrypted data will remain inaccessible until the ransom is paid or the device is formatted.

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.
