GandCrab v5.2 Ransomware was released just few hours before Europol, Romanian Police and Bitdefender released full-functional decryption tool for all previous versions of virus, up to GandCrab v5.1 Ransomware. Updated version of GandCrab adds .[5-6-7-8-9-10-random-letters] extension and ransom note file will get such name: [5-6-7-8-9-10-random-letters]-DECRYPT.txt and [random-letters]-DECRYPT.html. It is reported that many IT companies and managed service providers have been infected and affected by the GandCrab Ransomware. Some of the previous versions had decryptor from BitDefender, we will provide download link for this tool below. There is a possibility, that program will be updated to work with GandCrab v5.2 Ransomware. Meanwhile, we recommend you to use standard Windows functions, such as shadow copies, previous versions of files, restore point to attempt recovering your files. Using special file-recovery software often helps to restore many files, remover by the user earlier and not touched by the virus.

How to remove Dharma-ETH Ransomware and decrypt .ETH files

Standard

Dharma-ETH Ransomware is new generation of high-risk Crysis-Dharma-Cezar ransomware family, particularly, its Dharma variation. It was named after the extension it appends to encrypted files: .ETH. In fact, virus adds complex suffix, that consists of several parts: e-mail address, unique 8-digit identification number (completely random) and .ETH extension. In the end, affected files get complex suffix, that looks like this – .id-{8-digit-id}.[{email-address}].ETH. Ransom notes do not contain information about the amount users need to pay to return the files. There is also no information about encryption algorithms it uses. However, from the experience of previous infections of this type, we can say it, probably, uses AES or RSA-2048 encryption and will try to rip you off on a sum from $500 to $1500, that have to be paid in Monero, Dash or BTC (BitCoins).

How to remove Dharma-KARLS Ransomware and decrypt .KARLS files

Standard

Dharma-KARLS Ransomware is new virulent file-encryption threat, built on well-known platform of Crysis-Dharma-Cezar ransomware family. Unlike other variations, this version adds .KARLS extension to encrypted files. Actually, Dharma-KARLS Ransomware creates complicated appendix, that consists of unique user id, developer’s e-mail address and .KARLS suffix, from which it got its name. The template of filename modification looks like this: file called 1.doc will be converted to 1.doc.id-{8-digit-id}.[{email-address}].KARLS. Authors of Dharma-KARLS Ransomware can extort from $500 to $5000 ransom in BTC (BitCoins) for decryption. Using cryptocurrency and TOR-hosted payment websites makes it impossible to track the payee. Besides, victims of such viruses often get scammed, and malefactors don’t send any keys even after paying the ransom. Unfortunately, manual or automatic decryption is impossible unless ransomware was developed with mistakes or has certain execution errors, flaws or vulnerabilities.

How to remove Obfuscated Ransomware and decrypt .obfuscated files

Standard

Obfuscated Ransomware (BigBobRoss Ransomware) is dangerous encryption virus, that uses AES-128 encryption algorithm to cipher user’s files. After successful encryption it appends .obfuscated extension (latest versions also add prefix [id={8-digit-code}]). Obfuscated Ransomware creates ransom note called Read me.txt, and puts it on the desktop and in the folders with encoded data. It also modifies desktop wallpaper, placing text on white background. Malefactors allow to decrypt 1 files under 1 Mb of size for free, as a proof of operability. Obfuscated Ransomware attacks sensible files, such as photos, videos, documents, databases, etc. Virus focuses on English-speaking users, which does not prevent spread throughout the world. The first victims are from Moldova. It is currently unknown, how much they want for decryption. Of course, we do not to pay the ransom, as there are many cases when hackers don’t send master keys or decryptors. There is still a chance decryption tool will be released by antivirus companies or security enthusiasts.

How to remove Pluto Ransomware and decrypt .pluto files

Standard

Pluto Ransomware is harmful file-encrypting virus, that blocks access to user’s files by encoding them and adding .pluto extension. After encryption malware developers extort ransom to be paid in bitcoins. Pluto Ransomware creates ransom note called !!!READ_IT!!!.txt, where decryption routine and contact information are described. As our experience shows, ransom varies between $500 and $1500. Malefactors send cryptocurrency wallets to receive payment in Bitcoins or Ethereum. There are no way to track the payments, as such wallets are anonymous. Of course, we never advise to pay the ransom, as there are many cases when hackers don’t send master keys or decryptors. There is still a chance decryption tool will be released by antivirus companies or security enthusiasts.
