New variant of the Samas ransomware has been reported to demand the sum of 1.7 bitcoins after it uses RSA encryption to encipher files of infected computers, adding the .iloveworld file extension to them. The ransomware then drops a PLEASE_READ_FOR_DECRYPT_FILES_{number}.html file which contains a long ransom note with instructions on how to pay 1.7 BTC to the cyber-criminals behind the virus. In case you have been infected by this virus, it is strongly inadvisable to conduct any ransom payoff since this may help cyber-criminals further replicate Samas ransomware. Instead we recommend following the instructions after this article to remove this virus and try to restore your files.

Samas Ransomware’s Distribution Technique
The Samas virus may use different techniques to be spread. It may use pen testing deployment sent out from a remote server to cause infection. Such software gives an opportunity for cyber-crooks to discover vulnerabilities and select the correct exploit kit or obfuscator that will allow a successful infection.
Samas Ransomware – More Information
Similar to the previous variant of Samas ransomware virus, this one may also take advantage of activities which it has copied from a variety of other viruses in its code. One particular tool that has been reportedly associated with Samas ransomware is called PsExec, and it’s primary file is pre-programmed to remotely execute programs on the infected computer.
Not only this, but the Samas virus may also use other features from a Trojan horse, also known and detected as Samas, which was most likely created by the same developers.
The main executable of Samas ransomware is reported to be named gotohelldr.exe and it may include scripts such as the one that deletes the shadow copies on the infected computer with the following vssadmin command in quiet mode:
Such commands might be used by the Samas virus to get rid of all the backups and file history on the affected device.
In addition to this, the virus may also download other malware on the infected computer, such as an MSIL trojan and other ransomware as well.
Samas Virus’s Encryption Process
To encrypt files the Samas ransomware may scan your computer for a wide variety of file types, for example:
→ “PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML. DOC .DOCX .LOG .MSG .ODT .PAGES .RTF .TEX .TXT .WPD .WPS .CSV .DAT .GED .KEY .KEYCHAIN .PPS .PPT .PPTX ..INI .PRF Encoded Files .HQX .MIM .UUE .7Z .CBR .DEB .GZ .PKG .RAR .RPM .SITX .TAR.GZ .ZIP .ZIPX .BIN .CUE .DMG .ISO .MDF .TOAST .VCD SDF .TAR .TAX2014 .TAX2015 .VCF .XML Audio Files .AIF .IFF .M3U .M4A .MID .MP3 .MPA .WAV .WMA Video Files .3G2 .3GP .ASF .AVI .FLV .M4V .MOV .MP4 .MPG .RM .SRT .SWF .VOB .WMV 3D .3DM .3DS .MAX .OBJ R.BMP .DDS .GIF .JPG ..CRX .PLUGIN .FNT .FON .OTF .TTF .CAB .CPL .CUR .DESKTHEMEPACK .DLL .DMP .DRV .ICNS .ICO .LNK .SYS .CFG” Source:fileinfo.com
As soon as it detects the files it is pre-programmed to encrypt, the virus scrambles portions of their source code which are enough to render the files unusable. The portions of code are replaced with a very sophisticated RSA-2048 encryption algorithm, which is also reported to be classified as a Suite.B cipher used by the DoD for secret files.
Encrypted files by this variant of Samas contain the .iloveworld file extension after their names and may look like the picture below:
In addition to the encryption process, the Samas virus also drops a ransom note in the form of a .html file. The note is named PLEASE_READ_FOR_DECRYPT_FILES_{victimID} and has notification and instructions.
Samas Ransomware – Removal and Restoration of .iloveworld Files
Since Samas is also believed by malware researchers to be a part of a RaaS scheme (ransomware as a service) and it may come in different variants with the same source code, malware researchers strongly advise for affected users to wait for a decrypter.
Samas Ransomware should be removed manually by following the instructions after this article. In case you do not feel sure that you will fully remove it manually, malware researchers strongly advise using an advanced anti-malware program that will delete all files associated with Samas automatically.
In case your files have the .iloveworld file extension, this means they are encrypted. At this point, there is no official decryption solution for free. However, it is strongly inadvisable to pay the 1.7 BitCoin ransom money to criminals. Besides this, we have also offered alternative solutions to decrypt your files in case they have been encrypted by this virus. They are not 100% guarantee you will decrypt your files, but if you are in luck, you may restore some of your files this way. The instructions may be found in step “2. Restore files encrypted by Samas” below.

Step 2: Uninstall Samas and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Samas on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Samas there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Samas
Step 5: Try to Restore Files Encrypted by Samas.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Samas aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
