What is Caleb ransomware?

Caleb ransomware – a Phobos family member that adds a malicious executable to the %AppData% or %LocalAppData% folder

Caleb virusCaleb virus - ransomware that comes from the Phobos family

Caleb ransomware is considered to be a family member of Phobos malware. When this malicious strain lands on your machine, it places a bogus .exe file in the %AppData% or %LocalAppData% directories that scans the entire system for encryptable files and documents. Afterward, Caleb virus appends the .[].Caleb or just the .Caleb extension to each file that is locked by using symmetric[1] or asymmetric encryption algorithms. However, the aim of this threat is to carry ransom demands that are provided in the info.txt Notepad message and the info.hta pop-up. The criminals might be greedy and urge between $500 to $2000 in BTC. Also, these people provide the email address as their contact details where victims can send 5 small files that do not take more than 4 MB of space if they want to receive proof of the decryption key's existence and discuss all ransom-related conditions.

If you have been dealing with this lately, make sure to eliminate the hosts file, otherwise, you will remain blocked from antivirus-based websites.

Caleb ransomwareCaleb ransomware is a dangerous malware form that can modify the Windows hosts file

Nevertheless, Caleb ransomware might insert bogus entries into the Windows Registry. Malicious keys are most likely to be found in these typed of directories:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run;
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce;
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run;
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce.

Various entries and processes allow Caleb ransomware to run different types of modules. For example, the file-encrypting threat might be able to avoid antimalware detection and also boot up automatically every time when the user turns on his/her computer or laptop.

Before you opt for Caleb ransomware removal, you need to boot your computer in Safe Mode with Networking or use System Restore to discard all malicious changes that have been recently made by the cyber threat. After you do this, scan the entire machine with FortectIntego and look for infected software or files.

After you remove Caleb ransomware and malicious processes are no longer active on your Windows computer system, it is time to start thinking about data recovery possibilities. Even though .Caleb files remain barely decryptable at the moment, you still have a slight chance at restoring at least some data files by using the tools that are provided down below.

Facts why paying ransom might be dangerous and why hackers often ask for Bitcoin currency

Cyber threats such as Caleb ransomware are developed for collecting money from their victims by providing them with particular ransom demands. Some crooks are less greedy and urge for just a few hundred to be paid while others might be overloaded with greed and demand for more than a thousand dollars.

However, neither of these ransom demands should be fulfilled! There is a big risk to get scammed by people who distribute malware such as Caleb ransomware as they often just collect the money and runoff. This way you are left with no decryption option at all and an empty bank account.

Besides, cybercriminals often urge for some type of cryptocurrency (Bitcoin most of the time) as these types of currency transfers do not require entering any personally-identifiable information so the hackers can remain in secret and uncaught by authorities as they are not requested to reveal their identity during payment transactions.

Ransomware distribution happens through email spam or RDP mostly

Security experts from[3] notify all users what type of sources they should be aware in order to avoid possible ransomware attacks. Most commonly, this malware disguises as an email message from a reputable shipping company like DHL or FedEx and tends to send random victims false order information.

The malicious payload usually resides in a fake confirmation link which users are encouraged to click in order to confirm some type of non-existing order or comes planted in an attachment of a certain executable, word, ppt, zip, rar, dll, or other files. Do not open any questionable attachments before scanning them with antimalware!

Continuously, hackers are known to have the ability to attack certain RDP, mostly the TCP port 3389 and forcibly connect to the targeted machine. Last but not least, some ransomware-related payload can be discovered on peer-to-peer networks such as The Pirate Bay and its downloading links that included cracked software/videos.

Learn to protect your data

Almost everyone less or more has some valuable documents (paid bills, agreements, online transfers) stored on their computers and laptops. However, there are many bad actors who are very likely to capture that kind of information, lock it up and urge for big ransomware demands in order to release the files.

Regarding this fact, you need to know that keeping only original variants of important documents only on your computer might be not safe. You should make at least one copy of your files (multiple copies would be even better) and store them in different locations, remotely would be the best option.

Nowadays we have a lot of different options on how to keep our data safe. First of all, you can purchase and USB drive and copy your files to this device. Just make sure that you keep the USB unplugged when it is out of usage, otherwise, if a ransomware attack occurs and the device is plugged, files that are stored there might also get affected.

In addition, you can use remote services such as Dropbox or iCloud to keep copies of data there also. However, the best variant would be to keep multiple copies in a remote drive, remote server, and in another computer. This way you will slightly decrease the chances of getting your data permanently lost during a malware incident.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
