What is Cales ransomware?

Cales ransomware is the cryptovirus that keeps user form accessing the system with administrative rights and makes other system changes

Cales ransomwareCales ransomware is the virus that infects the system and marks files with .[].cales extension when data gets encoded. Cales ransomware is a version of one of the more persistent and dangerous threats – Phobos ransomware.[1] This virus is set to target victims on a global scale and since this old threat family, hackers behind the threat seem to be experienced and dangerous. This is why we don't recommend paying or even contacting them. Once your files get marked using a file extension with .cales, other commands can be executed behind your back. There are many actions that follow after the initial encryption process. This threat loads svchost.exe file and other scripts to keep you from altering the settings, sometimes you cannot even enter the administrative mode due to the threat, so you should react to this infection as soon as the ransom demand is displayed before you.

Various campaigns of the Cales ransomware virus can be set to run commands on the infected machine that affect the performance, particular programs and even can damage the machine, interfere with file recovery later on. Although the virus is set to target particular file extensions when encrypting data, system folders, programs, and other functions get altered behind your back, so ransomware is more persistent than you can think. Criminals behind the threat are focusing on blackmailing their victims, so you should avoid paying the decryption fee since there is no real guarantee that you will get your data recovered by them.

Elimination For thorough Cales ransomware removal, you need a professional anti-malware tool that can clean the system fully from threats and fix virus damage

Cales ransomware is the file-encryption based threat that spreads on the machine without any permission and once the encoding is done it delivers the ransom note which demands victims to pay to get their files allegedly restored. Unfortunately, instructions and the message displayed in infro.txt or info.hta files are pre-determined and only contains general information about the ransomware attack.

Once you go to the site Cales ransomware redirects you to or contact the criminals via emails, you get to the payment system where particular amount shows up and Bitcoin wallet address belonging to the criminals is showed. Those instructions provide a few addresses where you can buy a cryptocurrency and pay the ransom.

Although criminals claim to have the only solution for your files, those malicious people may disappear after the transfer and your data remains locked. So no experts[2] in cybersecurity world will recommend paying the ransom for Cales ransomware or any other virus developers.

When info.hta program window shows typical instructions for Phobos ransomware family, a text file with the same info name is more unique for the particular Cales ransomware because it is the file that provides contact emails unique for the creators of this specific version. The message reads:

!!!All of your files are encrypted!!!
To decrypt them send e-mail to this address:
If we don't answer in 24h., send e-mail to this address:

You need to stay away from contacting these criminals because, in most cases, criminals behind such threats like Cales cryptovirus may be gready and ask for more money once you transfer the initial amount. This is how you can lose your files and money permanently. .[].cales virusCales ransomware is the malware written in codes, so various files get scattered in the system to keep the malicious script running. You should focus on Cales ransomware removal immediately after noticing the suspicious activity and receiving the ransom demand, but there are a few things you should do to protect your files. Firstly, when you think about the future of your encrypted files, you need to asses if you have any file backups stored on a different device or cloud database. If so, you can remove the threat without thinking twice and recover those files this way.

However, for the people that have no backups, we recommend waiting before terminating Cales ransomware. Firstly, you should look for a particular decryption tool provided by researchers:

When you know that this version has a decryption tool, before you remove Cales ransomware with all the traces and files, you should store encoded files, other data regarding the infection on a different device and clean your machine. For the proper job, you should go for the anti-malware tool like FortectIntego.

When you remove all core files, the virus is terminated, but when you do that with Cales ransomware files and still want to use the decryption tool it may be difficult. Anti-malware tools are disabling autorun entries pointing to the threat and that is okay. But once the AV tool quarantines the infection, it is important not to delete malware from quarantine or delete files without backing them up. These malware samples help with decryption later on. We have a few other tips below the article for file recovery without any backup or decryption options. Cales ransomware virusCales ransomware is the cryptovirus that makes files unopenable, so people feel more scared and eager to pay up.

Hackers are experienced enough to use different techniques of virus spreading

This virus family is known for a while, but each version appears to be modified just slightly and the base code is made custom to keep the malware persistency up. Previous versions in the family are known for being distributed different, but the most common methods include malicious files either planted in phishing campaigns or included on file-sharing networks.

Pirated software, free downloads from unofficial sources and torrent files can carry more than you think or expect because malicious actors pack executables and files containing malicious scripts. Once you download the needed software crack or a cheat code package for the video game the encryption starts immediately because the infected file is executed once loaded on the PC.

If you want to avoid such infections, go for legal sharing sites, official providers, restrain from torrent services. Also, pay attention to received emails and files attached to the suspicious email sent fro unknown sender. Malicious actors can disguise as anyone or anything, so even use the familiar name of a company in such emails. Delete anything you didn't expect to get and don't open files from unfamiliar emails.

Terminate Cales ransomware as soon as you can to avoid permanent damage to your device

Since Cales ransomware virus belongs to a family of malicious threats, there is additional possibility that script includes additional security bypass module and this malware dan disable your antivirus tools, security features of the device itself. This is why you should get a different anti-malware program and use it to delete the virus.

The proper Cales ransomware removal results can be achieved when you scan the machine fully and follow the detection[3] results, suggestions of what to eliminate. Automatic system scan shows all intruders and virus damage, the possible danger for the system.

Then you need to remove Cales ransomware, check for anything leftover with FortectIntego, SpyHunter 5Combo Cleaner, or Malwarebytes again and you can focus on data recovery. The best method is to replace encrypted files with copies from the cloud database or external device, but some third-party program can also work.

If your files are encrypted by Cales, you can use several methods to restore them:

Data Recovery Pro is the third-party program capable of restoring your data after Cales ransomware virus

When you need an alternate method for file backups Data Recovery Pro can help with accidentally deleted or encrypted files

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Cales ransomware;
  • Restore them.

Windows Previous Versions is the feature helpful for your encrypted files

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
