Onion ransomware lurks in TOR, enormous extortion sum payable in cryptocurrency
Onion ransomware is one of many encryption trojans that communicates with its victims via The Onion Router (TOR). It owes its name to being one of the first encrypting plagues that leverage the TOR anonymity. In particular, it tries to aggravate the detection of its remote Command and Control server locating it in the Onion network.

The victims of its attack face a communication from the ransomware. The infection drops relevant ransom note into any folder that undergoes the decryption. It is also available on the desktop.
The communication of the scammers lays down what is going on. It says the ransomware has locked your computer. Technically, it is not quite so. The extortion trojan only blocks access to the personal data concerned. The system remains functional. The hacker’s design implies the users read the ransom note and pay the amount demanded immediately from the compromised device. Thereby, system and certain program files remain readable. To restore readability of other files, the infection demands a ransom. The amount is to be paid in bitcoins and typically ranges within 3 to 4 BTC. Converted into fiat currency, the sum is essential as 1 BTC is currently traded for over USD 1000. The crooks wait 72 hours for the executed payment details. They indicate email@example.com as an email for transferring such information.
To keep the data encoded, the Onion trojan makes use of the RSA encryption. This is the asymmetric algorithm, meaning the private and public keys do not coincide. There is no obvious link between those keys. The attackers use the public key to process the data on the host machine. This key enters the compromised device, which is never the case with the private key. Any interception of data communicated between the hacked device and the remote server cannot contain the private key.
The above shall not sound a suggestion to buy the decryptor as prompted by the crooks. Quite in contrary, any payments do not ensure the removal of Onion encryption. You rather achieve greater recovery with the ransom-free routines available below.
Automated cleanup to remove Onion encryptor
Infection vector for ransomware typically features a trojan. The one in question definitely subscribes to that routine. The trojan drops its body into target computer and proceeds with disabling the detecting functionality of any security solution installed. The antivirus is thus unable to spot introduction of virus from the remote server.
The ransomware invasion is indicative of its dropper residing in the computer memory. It also hints at other invasions. The PC can hardly be considered properly protected due to the impacts of the above trojan.
Ultimate option implies a total formatting for any drives of your PC. That is not an option for many users, for it destroys all the data hosted by the machine. The best solution to pick would be in-depth system examination with a reliable security suite.
The trojan that has installed Onion ransomware, unless removed, is to trigger its installation campaign as soon as a new strain of ransomware is available. Thereby, it is critical to kill it as soon as possible.
The technique successfully overcomes malicious software, including any ransoming threats. It deploys a reputable security suite that offers not a single chance for malicious components to avoid detection and extermination. The software is incredibly user-friendly and operates on a single-click basic.
It is good to note the removal of Onion ransomware does not recover the data affected. However, the virus is subject to compulsory extermination or else is going to introduce related infections into the machine.
1. Click the button to download the stub installer and go through several setup dialogs. Once the tool is up and running, click Start Computer Scan
2. Wait until the cleaner checks the PC for Onion malicious code. As soon as the scan is completed, the report will list all malware objects spotted in the system. Make sure the entries for detected infections are checked, and select the Fix Threats feature. This will result in malware removal and system remediation, so you should now be good to go.
Restore the encrypted files
Onion ransomware encryption is a sophisticated data modification. There is no simple and single solution to cover all the cases. Transferring the ransom as demanded by the crooks is not the way either.Kindly apply the methods outlined below as they have been carefully developed to provide a recovery help for the most severe cases of encrypting assaults.
Data recovery with automatic software
Good news is that the virus actually deals with copies of the files. The originals have been deleted. The removed data still can be restored by virtue of such tools as Data Recovery Pro.
Shadow Volume Copies
As Windows creates backups at given periods of time, a victim is advised to address relevant restore points. Unfortunately, the method cannot apply unless the System Restore had been enabled prior to the invasion. Please also note the recovery returns files as saved before the time associated with the restore point addressed.
- Previous Versions dialog to target individual files
One can open Properties for any file. The menu has a tab called Previous Versions. It indicates versions of a file that have been backed up.
To make use of the feature, right-click an affected file and choose Properties in the drop-down list. Proceed with clicking the above-mentioned tab. You can opt between the Copy or Restore procedures, the former enabling to copy the item into the location specified by the user.
Backups and removing remaining traces of Onion ransomware
Prevention is the best cure. If you stick to making regular reserve copies of your data and store those outside your operating system, the impacts by the ransomware are very limited. However, prior to copying the data from backups into the system hit by Onion encryptor, make sure the removal of this virus has completed.
Your manual removal attempts may kill the ransomware in general. In most of the cases, some remnants manage to survive and are still capable of causing a significant damage. Please apply a reliable anti-malware scanner to detect and remove, if applicable, any remaining infections.
