Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading Restoro to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is SkyStars ransomware? And how does it implement its attack?
SkyStars ransomware is a new file-encrypting virus discovered as of late. It is designed to leave files corrupted and inaccessible to victims by locking them and then demands ransom from its victims. It adds a “.SKYSTARS” extension in every file it encrypts. Based on the analysis done by security experts, it appears that SkyStars ransomware is a new variant of the BlackMoon banking Trojan.
The instant it infects a computer, SkyStars ransomware will drop a Trojan executable file which is used to initiate the attack. This dangerous file is then used to perform a series of tasks in the system which allows the crypto-malware to stay invisible from any antivirus programs. Aside from that, they also make some modifications in some registry entries so that SkyStars ransomware can run every time a victim starts the computer, the crypto-malware can run automatically. It then begins to look for the 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
Once the aforementioned files are found, SkyStars ransomware will begin the encryption by employing the AES encryption algorithm. After the encryption is completed, it appends the .SkyStars extension on every affected file. It also drops a file named “SKYSTARSRANSOMWARE.txt” which reads:
“YOUR FILES ARE ENCRYPTED !!!
As you can see, there are no further details provided in the ransom note of SkyStars ransomware except for the email address you have to contact in order to decrypt your files. However, reaching out to the crooks behind this crypto-virus is definitely not recommended as crooks tend to demand a huge ransom. And besides, even if you pay the ransom, there really is no guarantee that these crooks will give you the encryption key or the decrypter used for file recovery.
How is the payload file of SkyStars Ransomware distributed online?
The payload file of SkyStars ransomware may be disseminated using various methods but it could mostly spread via malicious spam email campaigns. Typically, cyber criminals will attach an infected file in emails. This malicious file may be a PDF file, ZIP file or a document with macro scripts used to run SkyStars ransomware in the system. This is why before you download and open any attachment, you must double check the email first to verify if it’s safe to open.
