Black Worm ransomware is a dangerous file locking virus that appends .bworm extension
Black Worm ransomware is a file locking virus that uses AES cipher to encrypt data and asks ransom to set it free
Black Worm ransomware is a crypto malware that derived from HiddenTear open source project. Once the virus infects the computer, it performs a scan to detect photos, videos, music, and other files. It then uses the AES encryption algorithm to encode data and adds .bworm file extension. At this point, a personal ID is generated and is sent to the remote server controlled by hackers. Victims can also view a ransom note REAT_IT.txt that is placed in every single folder where altered files are located. Users are faced with the harsh truth: they are informed that all their personal files are inaccessible and the only way to get them back is by paying $200 worth of Bitcoin. Unfortunately, there is no Black Worm ransomware decryptor available yet, and users might not be able to ever return their files.
|Ransom demand||$200 in Bitcoin|
|Infection source||Spam emails, unprotected RDP, malicious websites, fake updates, etc.|
|Elimination||Use security software like ReimageIntego or SpyHunter 5Combo Cleaner|
Cyber blackmail is one of the most prevalent illegal money-making schemes, and hackers have been using ransomware viruses for over a decade now. Up till this day, file locking malware remains one of the most devastating cyber infections. Unfortunately, Black Worm ransomware removal will not return the access to the files. Nevertheless, such a process is necessary for a normal computer operation.
Black Worm virus makes several changes to the system, including:
- Alters/adds registry keys;
- Creates ADS file to hide malicious files;
- Attempts to delete Shadow Volume Copies;
- Drops several executables;
- Launches svchost.exe string that runs the malware.
In order to revert these modifications, users need to remove Black Worm ransomware from their computers. While manual elimination is possible, it is not recommended, as only trained IT professionals can perform it. For regular users, we recommend using security software like ReimageIntego, SpyHunter 5Combo Cleaner, or any other program that can detect Black Worm virus.
Many users might be considering the possibility of paying the ransom of $200, but experts highly discourage victims from contacting crooks. Sure, it is one of the options available, but it increases the risk of losing nor only personal files, but also the paid money. Over the years, many victims ended up with nothing after transferring the money to criminals. Therefore, they cannot be trusted.
Those who keep backups are in luck – restoring files encrypted by Black Worm ransomware will be easy. Those who do not have such an option should try third-party software that might be able to help with at least partial data recovery. And, finally, security researchers are always working on creating free decryptors for malware victims, and projects like No More Ransom helped millions of users worldwide. Thus, if nothing works, make a copy of your files and wait.
Black Worm is a data locker that was first discovered in mid December 2018
Ransomware distribution techniques
In most cases, users do not know much about ransomware, let alone its distribution methods. Therefore, the vast majority of victims that gen infected are either less computer savvy or simply not attentive enough. Nevertheless, there are several precautionary measures that you can practice to avoid the dreadful infection. Here are some of the tips:
- Install reputable anti-malware software that is capable of stopping most of the malicious software from infecting the PC;
- Avoid visiting questionable sites, including file-sharing, torrent, porn, gambling, and similar;
- Beware of spam emails – that attachment or hyperlink might contain malware;
- Beware of bundled software, some installers might be modified and injected with a malicious script;
- Patch your software as soon as updates are released – they fix critical security vulnerabilities that can be exploited by malware authors;
- Use tools like VirusTotal to scan executable and other files before opening them;
- Use strong passwords for all your accounts (use password manager).
Additionally, because no security measures can prevent the malware infection completely, you should backup your files on a regular basis.

- Restore them.
Windows Previous Version Feature might help you recover files
This option is only available if you had System Restore enabled before the infection occurred.
- Find an encrypted file you need to restore and right-click on it;
- Select “Properties” and go to “Previous versions” tab;
- Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.
ShadowExplorer might get all of your data back

No decryptor is available
Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Black Worm and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
