SkyName Ransomware – Infection Spread

SkyName ransomware could spread its infection by utilizing various methods. One of these ways is with spreading the payload as an executable file. When that .exe file is executed, the malicious script inside it will infect your computer machine. The executable might be presented as a one for a useful, free program. There have been multiple detections of one such file with its original name being ”blablabla.exe”. You can view the analysis of one of the executables with that name which contain the payload script, from the screenshot of the VirusTotal website right here:

SkyName ransomware could be spreading that payload file on social media networks and services for file-sharing. The script with the malware might be hidden inside the installation setup of programs presented as legitimate. Do not blindly open files you have just downloaded from the Internet, especially ones which come from suspicious sources, like links and e-mails. Beforehand, scan them with a security tool and check their size and signatures for anything that seems unusual. You should give a read to the ransomware preventing tips given in a topic in the forum section.

SkyName Ransomware – In Detail

The SkyName virus is ransomware that is written in the Czech language and is still in development. Thus, it doesn’t encrypt files or at least the samples that malware researchers have analyzed do not encrypt. SkyName is a variant of the open-source ransomware project HiddenTear.

SkyName ransomware could place multiple entries in the Windows Registry to achieve some a higher level of persistence. The registry entries can make the ransomware launch automatically with every boot of the Windows operating system and show its ransom note on startup.

If you get infected by this ransomware threat, its ransom message will appear in a window, while the ransom note will be saved on your computer’s desktop as a file called INFOK1.txt. Those messages will contain the instructions for payment. You can preview the ransom message from the snapshot provided right here:

The ransom note reads the following:

Vas pocitac byl hacknut a vaše soubory zašifrovaný tak, abyste k nim nemel i přistup!
Pošlete 1000 korun v bitcoinech na adresu
a pote si napište e-mail na adresu:
[email protected], do e – mailu uvedte id:
[Redacted] a dostanete desifrovaci klic a program, kterým soubory zase odemknete.
Tato zprava je dostupná na plose v souboru INFOK1.txt

This is how the INFOK1.txt file looks like:

The following addresses are left for contacting the cyber criminals:

The ransom that the criminals want you to pay is 1,000 Estonian Kroons which amounts to around 85 US dollars. The addresses given above and other data about the ransom demands are written in this article for informative purposes only. You should NOT in any circumstances consider contacting the crooks or paying them. That may only result in the cyber crooks being motivated to continue making viruses or pursue other criminal activities.

The SkyName ransomware might encrypt files using the AES encryption algorithm which is known to be used by viruses which are variants based on the HiddenTear open-source project. Some of the extensions of files which those virus variants usually search to encrypt are the following:

→.doc, .docx, .pdf, .db, .jpg, .png, .ppt, .pptx, .txt, .xls, .xlsx

The SkyName virus is entirely likely set to erase all Shadow Volume Copies from the Windows operating system by utilizing the command given here:

→vssadmin.exe delete shadows /all /Quiet
