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 LosVirus.es 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.
