About this ransomware

.Calum files ransomware will lock your files and request that you make a payment in exchange for their decryptor. Having a system infected with ransomware could have highly severe consequences, which is why it is categorized as such a dangerous threat. Ransomware does not lock every single file but actually scans for specific file types. It’s likely that all of your photos, videos and documents were locked because those files are the most vital. The key necessary to unlock files is in the hands of crooks are to blame for this malware. If the ransomware is decryptable, malware specialists might be able to release a free decryptor. If backup is not available and you have no other option, your best option may be to wait for that free decryption tool.

On your desktop or in folders with encrypted files, a ransom note will be placed. If it’s yet to be clear, the note should clarify what happened to your files, and offer a decryption tool for a price. It should not surprise you but paying crooks anything isn’t encouraged. We would hardly be surprised if crooks just take your money without you getting anything. They might guarantee to send you a decryption tool but who will guarantee they keep that promise. We would suggest you purchase backup with some of that money. In case you have made copies of your files, simply eliminate .Calum files ransomware.

The spread methods used will be explained more thoroughly later on but the short version is that you probably fell for a false update or opened a malicious spam email. Those methods are very common among cyber criminals.

Ransomware distribution ways

You likely got the ransomware through spam email or fake software updates. Since malicious spam campaigns are pretty common, you need to learn what dangerous spam look like. Always attentively check the email before you open an attachment. It’s also rather usual to see hackers pretending to be from known companies, as a familiar name would make people less cautious. For example, they could claim to be Amazon and say that they have added a receipt for a recent purchase to the email. Whether it’s Amazon or whichever other company, you should be able to easily check whether it’s true or not. Simply locate the actual email addresses used by the company and see if your sender’s is among them. You should also scan the attached file with a malware scanner to ensure that it will not cause damage to your system.

The malware could have also used bogus updates to enter. Oftentimes you may run into fake update alerts when on questionable websites, pushing you into installing something very annoyingly. It is also pretty common for those fake update notifications to pop up as adverts or banners. Still, for those who knows that no real updates will ever be pushed this way, it will immediately become obvious. You ought to never download updates or software from sources like ads. If you’ve set automatic updates, you will not even be alerted about it, but if manual update is required, the application will notify you.

How does this malware behave

We probably do not need to explain that your files have been encrypted. The encryption process was launched soon after you opened the malicious file and you might not have even noticed, seeing as the process is pretty quick. All files that have been affected will now have an unusual extension. Your files have been locked using a complicated encryption algorithm, so don’t bother attempting to open them as there will be no use. A ransom note will clarify what happened to your files, and how you can restore them. The ransom notes usually tend to threaten users with file deletion and encourage victims to pay the ransom. Even if the crooks have the only decryptor for your files, paying the ransom isn’t a suggested option. The people accountable for locking your files will not feel bound to recover them even if you pay. If you give into the demands now, hackers could think you would pay again, therefore may target you specifically again.

Before even thinking about paying, check if you’ve uploaded some of your files anywhere. Our recommendation would be to store all of your encrypted files somewhere, for when or if specialists specializing in malicious software make a free decryptor. In any case, you have to eliminate .Calum files ransomware from your computer.

It is rather important that you begin backing up your files, and we expect you will learn from this experience. You may end up risking losing your files again if you do not. Backup prices vary based on in which backup option you opt for, but the purchase is certainly worth it if you have files you want to guard.
