Repp ransomware – the 203rd version of Djvu ransomware that is currently undecryptable
Repp ransomware is a file-locking virus that uses the AES-256 encryption cipher to lock up individual files and documents by adding the .repp appendix to each filename
Repp ransomware, discovered by Michael Gillespie, appears to be one of the newest Djvu ransomware versions that have emerged at the start of 2020. This malicious variant acts exactly the same as its other siblings and aims to target English-speaking people who are using Windows computers. The extension that the ransomware virus appends is .repp and is added to each file's name after the AES-256 cipher performs its encryption task. Furthermore, Repp ransomware drops the _readme.txt message in a Notepad blank that is placed on the desktop and in each folder that holds encrypted documents and files.

Cybersecurity experts from LosVirus.es claim that ransomware infections are most commonly spread through email spam. The crooks often pretend to be from reliable companies such as FedEx and DHL and deliver legitimate-looking attachments that come in forms of executables, word documents, and other formats.
Once the user opens the infected file, he/she receives the malicious payload straight on the Windows operating system. you should be aware of email messages that fall in the Spam section and avoid opening any emails that look questionable to you. Always identify the sender, check the letter's text for grammar mistakes and do not open any attachments that look suspicious to you. If you have already downloaded the file, scan it with an antivirus product.
Furthermore, file-encrypting cyber threats are delivered through cracked software that is included in peer-to-peer networks such as The Pirate Bay, eMule, and BitTorrent. You should use only original downloading sources for your wanted products and services. P2P sites and other untrusted websites should be avoided as they lack the required security and can easily be misused by malware developers for their own malicious purposes.

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.
