Zimba ransomware – a cryptocurrency demanding file-locking parasite
Zimba ransomware is a data-locking computer virus that focuses on money extortion
Zimba ransomware is yet another file-encrypting and ransom demanding computer virus from the infamous Dharma family. Most of the ransomware operates the same way. First, it encrypts the victim's personal pics, documents, audio, and other files and appends some sort of extension (in this case, a complex triple extension, ending with .zimba). Then it creates ransom notes that could either be pop-up windows or text files, placed everywhere so that the victim would find it easily.
Following a successful encryption, Zimba virus (similarly to its versions – Sss, MUST, and R3f5s) generates a pop-up window, named email@example.com, and ransom note text files, called FILES ENCRYPTED.txt. The message is very short and consists of just an email address to contact the criminals. The pop-up window, on the other hand, is a bit more instructive. Within it, the .zimba file virus creators explain that all victim files were encrypted and that the only way to get them back is by meeting their demands.
Two emails are provided saying that the second one should be used only if they don't respond within twelve hours, but the emails are the same – firstname.lastname@example.org, and a unique user ID is appointed. Then, the cybercriminals threaten the users not to try any third-party decryption tools or rename the files, leading to permanent data loss. No more info is given, nothing about the ransom size or the preferred payment method, no free decryption of a few files guarantees the victims that they really possess the needed tools for decryption.

Even though a ransomware infection is a nightmare that users want to wake up from immediately, but don't panic. We're here to help you. Don't even consider contacting the criminals even to find out the ransom amount to satisfy your curiosity. Paying the ransom is the worst thing that any ransomware victim can do because it empowers and fuels the cybercriminals, like the developers of Zimba ransomware, to initiate more attacks and create more sophisticated, undetectable malware.
People should get rid of the virus immediately. We suggest using powerful anti-malware apps like SpyHunter 5Combo Cleaner and Malwarebytes to remove Zimba ransomware from infected systems. Virus deletion won't decrypt your files, but it's what it should be done before attempting the file recovery.
When you're done with Zimba ransomware removal, we strongly advise doing a full system check-up with a powerful tool like the ReimageIntego to locate and repair any issues that the virus might have done to system files and its settings.
Message from the cybercriminals in the pop-up window reads:
YOUR FILES ARE ENCRYPTED
Don't worry,you can return all your files!
If you want to restore them, follow this link:email email@example.com YOUR ID –
If you have not been answered via the link within 12 hours, write to us by e-mail:firstname.lastname@example.org
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.
Zimba ransomware is a crypto-malware that hails from a broad family known as Dharma
The brief message from the ransom note text files:
Malware distribution methods
There are different kinds of malware, so it also spreads in different ways. But the most common ways cybercriminals are infecting everyday computer user's devices are file-sharing platforms and spam email campaigns. Nowadays, to stay safe while browsing, people should always have a trusty anti-virus software watching their backs.
While commencing spam email campaigns, cyber thieves send out thousands of spam emails across the globe. These emails contain one of two evils – either an infected attachment or a hyperlink to a malicious site. If either of these is opened, a payload file gets access to the computer, and infection is initiated.
Lots of malware is hidden in the torrent sites because anyone can upload anything onto there. It's an ideal place for cybercriminals to hide their creations camouflaged as popular game cracks, pirated software, and so on. To stay safe on the internet, please refrain from these sites so you can evade a massive headache.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Zimba and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes
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.
