Ransom:Win32/Spora.A – Initial Information
Ransom:Win32/Spora.A is a sort of file encoder program written up to stop you from using your computer or accessing saved data and asks you to pay off ransom to a malicious hacker. Unlike other ransomware, Ransom:Win32/Spora.A is released with worm capabilities. It mean the ransomware can arrive onto other computers connected to the same network. Due to having this ability, it could infect your home computers and friends computers easily when you share the same Wi-Fi connection or peer to peer network. During initial inspection we’ve seen this new variant of Spora family distributed via email as a macro-enabled document and as an HTML application (HTA) packaged in a Archive (.ZIP) file.
Ransom:Win32/Spora.A seems to be developed by Russian cyber crooks because it displays ransom note in Russian language. Indeed, the ransomware uses a highly strong RSA-1024 cipher to encode your files and generate encrypted private key and public key. Following data encryption, the ransomware stores private key (a.k.a unlock key/password or decryption) to its C&C server so that victims couldn’t access it without paying ransom. Next, the file encoder virus creates a ransom note file containing Public key as Unique ID. The note may contain information on how to get back your enciphered files and how to contact malicious hacker. Unlike other file encoder viruses, Ransom:Win32/Spora.A doesn’t change extension of encoded files to avoid generic detection. Thus, we can say that is is developed by highly skilled Russian cyber crooks.
