What is Velso ransomware? And how does it implement its attack?

Velso ransomware is a file-encrypting threat discovered on January 15, 2018. This crypto-malware is classified as a generic crypto-threat that is programmed to apply a customized AES 256 encryption algorithm on the targeted files. According to security experts, it is designed to encrypt files with the following extensions:
.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
As pointed out earlier, Velso ransomware uses AES 256 cipher in encrypting the targeted files listed above. It also obfuscates the decryption key using the RSA 1024 cipher. Once it’s done with the encryption process, it drops a file called “get_my_files.txt” which reads:
“Hello. If you want to return files, write me to e-mail
[email protected]
Your userkey: {KEY}”
Developers of Velso ransomware claims to offer a decryption program as long as you are willing to pay a few hundred dollars in Bitcoins – this is something you must not do no matter how much the cost is as you will only end up losing that money for nothing. And even if Velso ransomware deletes the shadow volume copies of the encrypted files that still shouldn’t make you resort to paying them as it would be futile. The best thing you could do for now is to wait until a free decryptor is released by security experts and use whatever backup copies you have of the affected files.
How does Velso ransomware proliferate?
Velso ransomware is found to be proliferating using malicious spam emails. This kind of spam emails usually contains an infected attachment which may be a malicious executable file (.exe) or a document with macro scripts or even a link that could redirect you to the downloader of Velso ransomware. To avoid such occurrences, you have to be very careful when opening emails, especially those that are in the spam folder. Cybercrooks tend to disguise these emails to make them look like their invoices, receipts, and other important documents to catch your attention so you have to beware of such tactics.

Step 10: Delete the registry keys and sub-keys created by Velso ransomware.
Step 11: Close the Registry Editor.
Step 12: Empty your Recycle Bin.
To make sure that Velso ransomware is completely removed and that nothing is left behind, use the following antivirus program. To use it, refer to the instructions below.
Perform a full system scan using SpyRemover Pro. To do so, follow these steps:
