Cve ransomware is malware than will encrypt files, and is part of the notorious Dharma ransomware family. The malware adds an extension to encrypted files that consists of the users’ unique ID and [email@example.com].cve. Also drops FILES ENCRYPTED.txt ransom note.
Discovered by malware analyst Marcelo Rivero, Cve ransomware is file-encrypting malware, one of Dharma ransomware newest versions. It encrypts files, adds a .unique id.[firstname.lastname@example.org].cve file extension and drops a FILES ENCRYPTED.txt ransom note. Users will be unable to open encrypted files, unless they are first decrypted. But to do that, users first need to acquire the decryptor specifically made for this ransomware. The cyber gang behind this ransomware will try to sell the decryptor to victims, but buying it is not recommended. When it comes to cyber criminals, there are no guarantees about what they’ll do, and the likelihood of them sending victims the decryptor in exchange for payment are pretty slim. Many victims in the past were left with no decryptor and lost money. Thus, paying the ransom is not recommended.
Unfortunately, there currently is no other way to decrypt files. We should mention that malware researchers do release free decryptors to help users recover files, but one for Cve ransomware is not yet available. Users should be very careful with where they download decryptors from, as there are many fake ones out there. Sources like NoMoreRansom, Emsisoft, other anti-virus programs and malware researchers are safe to download decryptors from.
File recovery should not be a problem for those who have backup. Once they delete Cve ransomware from their computers, they can immediately connect to their backup and retrieve the files. Ransomware is one of the main reasons why backup is so essential nowadays. With potential malware on every corner on the Internet, regularly backing up files is critical.
Ransomware spread methods
Ransomware uses a variety of methods to infect computers, including spam email attachments, torrents, software cracks, and malicious ads.
Users who pirate content have a significantly higher chance of picking up ransomware than those who don’t. That’s because torrent sites and forums are full of malware, mainly due to the fact that they’re not regulated properly. Malware operators have no trouble disguising malware in a torrent for popular movies, TV shows, games, software cracks, etc. Users who don’t know any better end up downloading and opening those torrents. So to greatly reduce the chances of infecting their computers with ransomware, users should stop pirating content.
Another common way users pick up ransomware is by opening malicious email attachments. Cyber criminals launch spam email campaigns using email addresses they purchase from various hacking forums. The spam emails carrying malware usually contain text that pressures users into opening the attached files by claiming they’re important documents. But if users pay attention to the emails they receive, they should be able to notice the signs that point to them being malicious. One of the most obvious signs is the email being full of grammar and spelling mistakes. Furthermore, they’re often sent from random email addresses. Overall, if users weren’t expecting an email, opening the attachment would be risky. All unsolicited email attachments should be scanned with anti-virus software or VirusTotal before they are opened.
Can victims recover Cve ransomware encrypted files?
It’s very likely that users won’t notice that their files are being encrypted by Cve ransomware until it’s already too late. Once files have been encrypted, they will have a .unique id.[email@example.com].cve extension added to them. Users will all be assigned unique IDs, which they need to mention if they were to contact the cyber criminals behind this ransomware. A ransom note FILES ENCRYPTED.txt will be dropped, and a pop-up ransom note will appear. It will contain information on how users can decrypt files, which involves users sending an email to firstname.lastname@example.org with their assigned ID.
The note does not mention the ransom sum, but it will likely be somewhere between $100 and $1000. As mentioned above, paying it is not recommended. Besides it not guaranteeing file decryption, by paying users will be supporting future malicious activities. Unfortunately, that leaves backup as the only way to recover files.
Here’s the ransom note dropped by Cve ransomware:

Cve ransomware removal
