.Osiris is a malicious encryption program. It belongs to the notorious strain of ransomware dubbed Locky.
The latter is widely known for its using a good deal of names derived from mythology. It used to rely chiefly on Scandinavian pantheon. Locky itself is a name of a divine thing praised by the Vikings.
.Osiris is a piece of ransomware. It encrypts your computer data and does not let you decrypt it back unless the ransom it claims settles to the bitcoin wallet of the crooks. The amount claimed by the crooks is easily adjustable, yet currently, most of the cases demand you to part with 0.5 BTC to the benefits of the invaders. The bitcoin rate of exchange to fiat currencies is nothing but stable. It is now around 1 BTC per USD 750 with overall tendency to grow.
.Osiris (Locky) “decryption console”
Leaping up ahead, the last things the victims should do is paying even a dime to the crooks. Removal of .Osiris may be critical but is done best with encryption-free workarounds.
Ransomware may sound like no other software, its impacts ominous. However, just like any kind programs, be those benign or malign, .Osiris ransomware needs to infiltrate the computer systems to be victimized. In doing so, the extortion virus in question exploits a number of schemes. The prevailing vector is only one, though. It leverages a variety of spamming scheme. That eventually aims at introducing .xls file into the system. It is basically an Excel spreadsheet with macros. The recipient needs to ‘enable the content’, that is to say, execute the macros. That would trigger the .Osiris virus installation.
files with .osiris extension
The installed instance of the rogue would first need to scan the computer memory. As a result, some files would not undergo the encryption. The reason why such a piece of malware would spare any items has nothing to do with the charity. It is just because the system cannot run; hence users cannot read the ransom note and pay the amount claimed, where its critical files become unavailable. That is to say, the only files which are likely to remain as is are the critical system files.
Modern encryption algorithms are deadly strong. To aggravate the situation, the virus applies two encryption systems at once, RSA and AES. Besides, the encryption extends to the filenames, too. The victims are unable to tell one item from another.
Again, the encryption is deadly strong. Moreover, any payments transferred to the crooks would not ensure you get the data decrypted as promised. Follow the guidance below to get rid of .Osiris ransomware and remedy the affected data.
Automated cleanup to remove .Osiris 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 .Osiris 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 .Osiris 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 .Osiris files 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
.Osiris 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 .Osiris 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 .Osiris ransomware, 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.
